The processor 214 may perform an overall control operation of the electronic device 200. For example, the processor 214 may control the overall operation of the electronic device 200.
The processor 214 may detect a change in the projection environment through the sensor 213. The processor 214 may determine whether the image needs to be corrected based on a change in the projection environment. The processor 214 may determine whether focus correction for an image is required. For example, the processor 214 may perform focus correction based on the projection distance and the projection angle. The processor 214 may determine whether keystone correction is required for the image. For example, the processor 214 may perform keystone correction based on the projection distance and the projection angle. The processor 214 may control the projection assembly 211 to output the corrected image on the projection surface. For example, the processor 214 may determine movement information about the projection lens based on the projection distance and the projection angle and perform correction of the image based on the movement information.
The processor 214 may obtain the detection data for measuring the distance between the projection surface and the electronic device 200 through the sensor 213. The processor 214 may obtain distance information between the projection surface and the electronic device 200 based on the obtained the detection data.
The processor 214 may obtain output size information about the image based on the distance information to the projection surface. Here, the output size information associated with the image may mean an actual size of the image output on the projection surface. Accordingly, even if an image having the same resolution is output, output size information about the image may be different based on distance information.
The processor 214 may obtain projection surface information based on the detection data obtained through the sensor 213. The projection surface may mean a space on which an image is to be output, and the projection surface may mean a wall, a screen, or the like.

The projection assembly 211 may be a component for projecting an image to the outside. The projection assembly 211 according to an embodiment of the disclosure may be implemented in various projection methods (e.g., a cathode-ray tube (CRT) method, a LCD method, a DLP method, a laser method).
For example, the CRT method may be basically the same as a projection method by a CRT monitor. The CRT method may magnify an image with a lens in front of a CRT and display the image on the screen. Depending on a number of cathode-ray tubes, the CRT method may be divided into a single-tube type and a three-tube type, and in a case of the three-tube type, cathode-ray tubes of red, green, and blue (RGB) may be implemented separately.
For example, the LCD method may be a method of displaying an image by transmitting light from a light source to liquid crystal. The LCD method may be divided into a single plate type and a three plate type, and in a case of the three plate type, light from the light source may be separated into red, green, and blue by a dichroic mirror (a mirror that reflects only light of a specific color and passes the rest), and then light may gather in one place again after passing through the liquid crystal.
For example, the DLP method may be a method of displaying an image using a DMD chip. A DLP projection unit may include a light source, a color wheel, a DMD chip, a projection lens, and the like. Light output from the light source may be colored while passing through a rotating color wheel. The light transmitted through the color wheel may be input to the DMD chip. The DMD chip may include numerous micromirrors. The DMD chip may reflect light input to the DMD chip using the micromirrors. For example, the projection lens may serve to magnify light reflected from the DMD chip to the size of the image.
For example, the laser method may include a diode pumped solid state (DPSS) laser and a galvanometer. As a laser outputting various colors, three (3) DPSS lasers may be installed for each RGB color, and then laser beams, whose optical axes overlap, may be used using a special mirror. The galvanometer may include a mirror and a high-output motor and move the mirror at high speed. For example, the galvanometer may rotate the mirror at up to 40 KHz/sec. The galvanometer may be mounted according to a scan direction, and in general, the projector may perform planar scanning, and galvanometers may be disposed separately in x-axes and y-axes.
The projection assembly 211 may include various types of light sources. For example, the projection assembly 211 may include at least one light source among a lamp, an LED, and a laser.
The projection assembly 211 may output an image, for example, in a 4:3 aspect ratio, a 5:4 aspect ratio, and a 16:9 wide aspect ratio according to the use of the electronic device 200 or user settings and may output an image in various resolutions such as WVGA (854*480), SVGA (800*600), XGA (1024*768), WXGA (1280*720), WXGA (1280*800), SXGA (1280*1024), UXGA (1600*1200), and full HD (1920*1080) according to the aspect ratio.
The projection assembly 211 may perform various functions for adjusting the output image under the control of the processor 214. For example, the projection assembly 211 may perform functions such as zoom, keystone, quick corner (e.g., four (4) corner) keystone, and lens shift.
In an embodiment, the projection assembly 211 may magnify or reduce the image according to the distance (e.g., projection distance) to the screen. In other words, the zoom function may be performed based on the distance from the screen. In this case, the zoom function may include a hardware-wise method of adjusting the screen size by moving (e.g., shifting) the lens and a software-wise method of adjusting the size of the screen by cropping the image.
When the zoom function is performed, it may be required to adjust the focus (e.g., focus correction) of the image. For example, the method of adjusting the focus may include a manual focusing method, an electric method, and the like. The manual focusing method refers to a method of manually performing focusing, and the electric method refers to a method of automatically performing focusing using a motor having a built-in projector when the zoom function is performed. When performing the zoom function, the projection assembly 211 may provide a digital zoom function through software and may provide an optical zoom function of performing the zoom function by moving the lens through a driving unit (e.g., driver).
Further, the projection assembly 211 may perform a keystone function (e.g., keystone correction). If a height of the electronic device 100 (e.g., the projection lens) does not match a front projection, the screen may be distorted up or down. The keystone function refers to a function of correcting the distorted screen. For example, if distortion occurs in a left-right direction of the screen, the distortion may be corrected using horizontal keystone, and if distortion occurs in an up-down direction, the distortion may be corrected using vertical keystone. The quick corner (e.g., four (4) corner) keystone function may be a function of correcting the screen if a central area of the screen is normal but corner areas are not balanced. The lens shift function may be a function of moving a screen if the screen is out of a normal screen area.
The projection assembly 211 may perform at least one of zoom correction, keystone correction, and focus correction by automatically analyzing the surrounding environment and the projection environment without a user input. In an embodiment, the projection assembly 211 may automatically perform at least one of zoom correction, keystone correction, or focus correction based on the distance between the electronic device 200 and the screen detected through a sensor (e.g., a depth camera, a distance sensor, an infrared sensor, or an illuminance sensor), information about the space in which the electronic device 200 is currently positioned, information about an ambient light amount, or the like.
The projection assembly 211 may provide a lighting function using a light source. In particular, the projection assembly 211 may provide a lighting function by outputting light using an LED. For example, the projection assembly 211 may include at least one LED. For example, the projection assembly 211 may output light using a surface light emitting LED. Here, the surface light emitting LED may refer to LEDs having a structure in which an optical sheet is disposed above the LEDs to evenly disperse and output light. In an embodiment, light output from the LEDs may be evenly dispersed through the optical sheet and be incident on the display panel.
The projection assembly 211 may provide a dimming function for adjusting the intensity of the light source. For example, if a user input for adjusting the intensity of the light source is received through the user interface 215 (e.g., a touch display button or a dial), the projection assembly 211 may control the LED to output the light of the intensity corresponding to the received user input. As another example, the projection assembly 211 may provide a dimming function based on content analyzed by the processor 214 without a user input. In an embodiment, the projection assembly 211 may control the LED to output light of the intensity based on information (e.g., content type, or content brightness) about the currently provided content.
The projection assembly 211 may control color temperature under the control of the processor 214. For example, the processor 214 may control the color temperature based on content of an image. In an embodiment, if the content is output as an image, the processor 214 may obtain color information about each frame of the content determined to be output. The processor 214 may control the color temperature based on the obtained color information for each frame. Here, the processor 214 may obtain at least one main color of the frame based on the color information for each frame. The processor 214 may adjust the color temperature based on the obtained at least one main color. For example, the color temperature adjustable by the processor 214 may be classified into a warm type or a cold type. Here, it is assumed that the frame to be output (hereinafter, referred to as an output frame) includes a scene in which a fire breaks out. The processor 214 may identify (or obtain) that the main color is red based on the color information included in the current output frame. The processor 214 may identify the color temperature corresponding to the identified main color-red. Here, the color temperature corresponding to red may be the warm type. The processor 214 may use an artificial intelligence model to obtain the color information or the main color of the frame. For example, the artificial intelligence model may be stored in the electronic device 200 (e.g., the memory 212). As another example, the artificial intelligence model may be stored in an external server capable of communicating with the electronic device 200.
The electronic device 200 may control the lighting function in conjunction with an external device. In an embodiment, the electronic device 200 may receive lighting information from the external device. Here, the lighting information may include at least one of brightness information or color temperature information set by the external device. Here, the external device may refer to a device connected to the same network as the electronic device 200 (e.g., an IoT device included in the same home/company network) or a device (e.g., a remote control server) that is not the same network as the electronic device 200 but is capable of communicating with the electronic device. For example, it is assumed that an external lighting device (e.g., IoT device) included in the same network as the electronic device 200 outputs red light at a brightness of 50. The external lighting device (e.g., IoT device) may directly or indirectly transmit lighting information (e.g., information indicating that red light is output at a brightness of 50) to the electronic device 200. Here, the electronic device 200 may control the output of the light based on the lighting information received from the external lighting device. For example, if the lighting information received from the external lighting device includes information indicating outputting of the red light at a brightness of 50, the electronic device 200 may output the red light at a brightness of 50.
The electronic device 200 may control the lighting function based on biometric information. In an embodiment, the processor 214 may obtain biometric information. Here, the biometric information may include at least one of a body temperature, heart rate, blood pressure, respiration, and electrocardiogram. Here, the biometric information may include various information other than the above-described information. For example, the electronic device may include a sensor for measuring biometric information. The processor 214 may obtain biometric information through the sensor and control the output of the light source based on the obtained biometric information.

As shown in (a) of
In an embodiment, the sensor of the electronic device 100 may include an image sensor that detects intensity and color information about light in a projection environment. For example, the image sensor may include at least one of a camera or a depth camera. The electronic device 100 may detect a change in the projection environment based on a change in light intensity and color information about the projection environment. For example, the electronic device 100 may detect a change in the projection distance and a change in the intensity and color information about light in the projection environment in combination of the distance sensor and the image sensor. For example, the electronic device 100 may detect a change in the projection angle and a change in the intensity and color information about light in the projection environment in combination of the tilt sensor and the image sensor. Further, the electronic device 100 may detect various projection environments in combination of an image sensor with at least one of an infrared sensor, an ultrasonic sensor, a laser sensor, and a LiDAR sensor.
In an embodiment, the electronic device 100 may determine a change in a projection environment based on the detection data detected by the sensor. In an embodiment, the electronic device 100 may identify a change in a projection environment based on at least one of a projection distance change, a projection angle change, and a change in light intensity and color information about the projection environment detected based on at least one of the distance sensor, the tilt sensor, and the image sensor. For example, if a change in the projection environment exceeds a pre-stored reference change threshold (or limit), the electronic device 100 may classify the projection environment change as a first environment change. For example, the first environmental change may include at least one of a fall of the electronic device 100, a drop of the electronic device 100, or a change in the physical position of the electronic device 100. For example, if a change in the projection environment is less than or equal to the pre-stored reference change threshold (or limit), the electronic device 100 may classify the projection environment change as a second environment change. For example, the second environmental change may include a slight change in the position of the electronic device 100 due to vibration of the electronic device 100 or an external physical force.
The reference change amount may include a projection distance threshold and a projection angle threshold. For example, if a change in the projection distance exceeds the projection distance threshold, the electronic device 100 may classify the projection environment change as the first environment change, and if a change in the projection distance is less than or equal to the projection distance threshold, the electronic device 100 may classify the projection environment change as the second environment change. For example, if the projection angle change exceeds the projection angle threshold, the electronic device 100 may classify the projection environment change as the first environment change, and if the projection angle change is less than or equal to the projection angle threshold, the electronic device 100 may classify the projection environment change as the second environment change. For example, the projection distance threshold and the projection angle threshold may be values set by the user.
The electronic device 100 may determine a correction operation to be performed on the image based on the classification of the projection environment change. In an embodiment, if the projection environment change of the electronic device 100 is classified as the first environment change, the electronic device 100 may perform both focus correction and keystone correction. For example, in a case of the first environment change, the electronic device 100 may perform keystone correction after performing focus correction. For example, in the case of the first environment change, the electronic device 100 may perform focus correction after performing keystone correction. In an embodiment, if the projection environment change of the electronic device 100 is classified as the second environment change, the electronic device 100 may perform only one of focus correction and keystone correction. For example, in a case of the second environment change, the electronic device 100 may perform only focus correction on the image. For example, in the case of the second environment change, the electronic device 100 may only perform keystone correction on the image. As another example, in the case of the second environment change, the electronic device 100 may determine that correction (e.g., the focus correction and the keystone correction) of the image is not required and may determine to not perform the correction of the image.
Further, the electronic device 100 may determine whether the change in the projection environment is due to a physical action of the user based on the the detection data detected by the sensor. For example, the electronic device 100 may determine whether the electronic device 100 is moved in a vertical direction based on the detected data. For example, the electronic device 100 may determine whether the electronic device 100 is moved in the horizontal direction based on the detected data. For example, the electronic device 100 may determine whether the electronic device 100 is moved in a first direction based on the detected data. Here, the first direction may include a direction (e.g., a diagonal direction) other than the horizontal direction and the vertical direction. For example, the electronic device 100 may determine whether the electronic device 100 is tilted in the horizontal direction based on the detected data. For example, the electronic device 100 may determine whether the electronic device 100 is tilted in the vertical direction based on the detected data. For example, the electronic device 100 may determine whether the electronic device 100 is tilted in the first direction based on the detected data. Here, the first direction may include a direction (e.g., a diagonal direction) other than the horizontal direction and the vertical direction. According to an embodiment, in operation 320, the electronic device 100 may determine whether focus correction is required based on a change in the projection environment. For example, after detecting the projection environment change, the electronic device 100 may determine whether the focus correction on the image output on the projection surface is required based on the change in the projection distance and the projection angle. In particular, the electronic device 100 may first determine whether focus correction is required, and then determine whether keystone correction is required. For example, if the focus of the image output on the projection surface is changed based on the change in the projection distance and the projection angle, the electronic device 100 may determine that focus correction is required. For example, if the focus of the image output on the projection surface is not changed based on the change in the projection distance and the projection angle, the electronic device 100 may determine that focus correction is not required.

For example, after determining whether focus correction is required, the electronic device 100 may determine whether the keystone correction is required for the image output on the projection surface based on the projection distance and the projection angle. For example, if the keystone of the image output on the projection surface is changed based on the projection distance and the projection angle, the electronic device 100 may determine that the keystone correction is required. For example, if the keystone of the image output on the projection surface is not changed according to the projection distance and the projection angle, the electronic device 100 may determine that the keystone correction is not required.

For example, the electronic device 100 may identify the correction result, and if it is determined that the correction is completed, the electronic device 100 may end the correction operation. For example, the electronic device 100 may identify the correction result, and if additional correction is required, the electronic device 100 may perform an additional correction operation on the image.

For example, after performing the correction on the image, the electronic device 100 may rewind (e.g., go back) the reproduction of the image output on the projection surface to the time when the correction is started and reproduce the image again. For example, if the electronic device 100 performs correction on the image, the electronic device 100 may select whether to pause or rewind the image based on a user input.

Accordingly, the electronic device 100 may output an image to only one area (e.g., PS1) of the projection surface. The electronic device 100 may determine the projection area occupying the largest portion of the projection surface as the output area based on the detected data L1, L2, and V_sen. For example, the electronic device 100 may determine a projection area (e.g., PS1) including the largest number of unit blocks on the projection surface as an output area.

The first support side (e.g., surface) 108a-1 may support the main body 105 if the electronic device 100 is mounted such that the outer side (e.g., surface) of the main body 105 touches the bottom surface, e.g., if the projection lens 110 is disposed to face the front side (e.g., surface). In an embodiment including two or more supports 108a, the emission angle of the projection lens 110 and the head 103 may be adjusted by adjusting the distance between the two supports 108a or the angle at which the hinge is opened.
The second support side (e.g., surface) 108a-2 may be a side (e.g., surface) in contact with the user or an external mounting structure if the support 108a is supported by the user or the external mounting structure and may have a shape corresponding to the grip structure of the user's hand or the external mounting structure not to slip off when the electronic device 100 is supported or moved. The user may fix the head 103 with the projection lens 110 directed toward the front side (e.g., surface), hold the support 108a and move the electronic device 100, and use the electronic device 100 like a flashlight.
The support groove 104 may be provided in the main body 105 to receive the support 108a if the support 108a is not used and may be implemented as a groove structure corresponding to the shape of the support 108a in the outer circumferential side (e.g., surface) of the main body 105. If the support 108a is not used, the support 108a may be stored (e.g., positioned) on the outer circumferential side (e.g., surface) of the main body 105 through the support groove 104, and the outer circumferential side (e.g., surface) of the main body 105 may be maintained seamlessly.
Alternatively, the support 108a may have a structure in which the support 108a is stored (e.g., positioned) inside the main body 105 and, if the support 108a is required, the support 108a may be pulled out (e.g., extracted) of the main body 105. In this case, the support groove 104 may be a structure of being recessed into the main body 105 to receive the support 108a, and the second support side (e.g., surface) 108a-2 may be brought in tight contact with the outer circumferential side (e.g., surface) of the main body 105, or a separate door (not shown) for opening/closing the support groove 104 may be included.
Although not shown in the drawings, the electronic device 100 may include various types of accessories that help to use or store the electronic device 100. For example, the electronic device 100 may include a protective case (not shown) to protect and easily carry the electronic device 100 or may include a tripod (not shown) for supporting or fixing the main body 105 or a bracket (not shown) coupled to an outer side (e.g., surface) to fix the electronic device 100.

The support 108b according to one or more example embodiments may be a handle or a ring provided to grip, hold, or move the electronic device 100, or the support 108b may be a stand that supports the main body 105 to face at an arbitrary angle while the main body 105 is laid down in the lateral direction (e.g., laid down on a flat surface).
In an embodiment, as illustrated in
Referring to
According to an embodiment of the disclosure, because the two supporting members 108c-2 have the same height, the respective cross-sections of the two supporting members 108c-2 may be coupled to or separated from each other by a groove provided in one outer circumferential side (e.g., surface) of the main body 105 and a hinge member 108c-3.
The two supporting members may be hinged to the main body 105 at a preset point (e.g., 1/3 to 1/2 of the height of the main body) of the main body 105.
When the two supporting members and the main body are coupled by the hinge member 108c-3, the main body 105 may be rotated about a virtual horizontal axis formed by the two hinge members 108c-3, such that the emission angle of the projection lens 110 may be adjusted.
Referring to
The cross section of the one supporting member 108d-2 may be coupled to or separated from a groove provided in one outer circumferential side (e.g., surface) of the main body 105 by a hinge member (not shown).
If the one supporting member 108d-2 and the main body 105 are coupled by one hinge member (not shown), the main body 105 may be rotated about a virtual horizontal axis formed by the one hinge member (not shown) as shown in
