According to an embodiment of the disclosure, the main body 103 may include a heat dissipation fan provided therein, and in case that the heat dissipation fan is operated, air or heat in the main body 103 may be discharged through the plurality of openings. Accordingly, the electronic apparatus 100 may discharge heat occurring due to the driving of the electronic apparatus 100 to the outside and prevent overheating of the electronic apparatus 100.
The connector 105 may connect the electronic apparatus 100 with an external device to transmit or receive electronic signals or receive power from the external device. The connector 105 according to an embodiment of the disclosure may be physically connected with the external device.

When being coupled to a conventional socket positioned on a ceiling, the electronic apparatus 100 may perform the projection top to bottom (vertically). Accordingly, by socket coupling, the electronic apparatus 100 cannot be rotated, and in this case, the screen cannot be rotated either. Accordingly, the electronic apparatus 100 may project or rotate the screen to the desired position while being socket-coupled to a stand on the ceiling by allowing the head 102 to swivel on one surface of the main body 103 to have an adjusted projection angle for the electronic apparatus 100 to be rotated even when being socket-coupled and receiving power.

The processor 111 may control overall operations of the electronic apparatus 100. The processor 111 may control overall operations of the electronic apparatus 100.
The processor 111 may be implemented as a digital signal processor (DSP), a microprocessor, or a time controller (TCON). However, the processor 111 is not limited thereto, and may include at least one of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a graphics-processing unit (GPU), a communication processor (CP), or an advanced reduced instruction set computer (RISC) machine (ARM) processor, or may be defined by these terms. In addition, the processor 111 may be implemented as a system-on-chip (SoC) or a large scale integration (LSI), in which a processing algorithm is embedded, or may be implemented in the form of a field programmable gate array (FPGA). In addition, the processor 111 may perform various functions by executing computer executable instructions stored in the memory 113.
The projecting part 112 may be a component that projects the image to the outside. The projecting part 112 according to an embodiment of the disclosure may be implemented in various projection types (e.g., cathode-ray tube (CRT) type, liquid crystal display (LCD) type, digital light processing (DLP) type, or laser type). As an example, the CRT type has basically the same principle as the principle of a CRT monitor. The CRT type may display the image on the screen by enlarging the image by using a lens in front of a cathode-ray tube (CRT). The CRT type may be divided into a one-tube type and a three-tube type based on the number of cathode-ray tubes, and in the three-tube type, the cathode-ray tubes of red, green, and blue are separated from one another.
For an example, the LCD type may display the image by allowing light emitted from a light source to pass through a liquid crystal. The LCD type may be divided into a single-panel type and a three-panel type. When the three-plate type, the light emitted from the light source may be separated into red, green and blue in a dichroic mirror (which is a mirror that reflects only light of a specific color and allows the rest to pass therethrough), may then pass through the liquid crystal, and may then be collected into one place again.
For still an example, the DLP type may display the image by using a digital micromirror device (DMD) chip. The DLP type projecting part may include a light source, a color wheel, the DMD chip, a projection lens, etc. Light emitted from the light source may be colored as passing through a rotating color wheel. Light passed through the color wheel may be input into the DMD chip. The DMD chip may include numerous micromirrors and reflect light input to the DMD chip. The projection lens may expend light reflected from the DMD chip to the image size.
For yet an example, the laser type may include a diode pumped solid state (DPSS) laser and a galvanometer. The laser type that outputs various colors may use a laser in which three DPSS lasers are respectively installed for red, green, and blue (RGB) colors, and their optical axes overlap each other by using a special mirror. The galvanometer may include a mirror and a high-power motor and move the mirror at a high speed. For example, the galvanometer may rotate the mirror at up to 40 KHz/sec. The galvanometer may be mounted in a scanning direction, and in general, a projector performs planar scanning, and the galvanometer may thus also be disposed by being divided into x and y axes.
The projecting part 112 may include light sources of various types. For example, the projecting part 112 may include at least one light source of a lamp, a light emitting diode (LED), and a laser.
The projecting part 112 may output the image in a screen ratio of 4:3, a screen ratio of 5:4, and a wide screen ratio of 16:9, based on a purpose of the electronic apparatus 100, the user's setting or the like, and may output the image having various resolutions such as wide video graphics array WVGA (854*480 pixels), super video graphics array SVGA (800*600 pixels), extended graphics array XGA (1024*768 pixels), wide extended graphics array WXGA (1280*720 pixels), WXGA (1280*800 pixels), super extended graphics array SXGA (1280*1024 pixels), ultra extended graphics array UXGA (1600*1200 pixels) and full high-definition HD (1920*1080 pixels), based on the screen ratio.
The projecting part 112 may perform various functions for adjusting the output image under the control of the processor 111. For example, the projecting part 112 may perform a zoom function, the keystone function, a quick corner (or four corner) keystone function and a lens shift function, or the like.
The projecting part 112 may enlarge or reduce the image based its distance (i.e., projection distance) to the screen. That is, the projecting part 112 may perform the zoom function based on its distance to the screen. The zoom function may include a hardware method of adjusting a screen size by moving a lens, and a software method of adjusting the screen size by cropping the image, or the like. In case that the zoom function is performed, it is necessary to adjust a focus of the image. For example, a method of adjusting the focus may include a manual focusing method, an electric focusing method, etc. The manual focusing method may indicate a method of manually adjusting the focus, and the electric focusing method may indicate a method in which the projector automatically adjusts the focus by using a motor built therein when performing the zoom function. When performing the zoom function, the projecting part 112 may provide a digital zoom function through software or may provide an optical zoom function in which the zoom function is performed by moving the lens by using a driving part 120.
In addition, the projecting part 112 may perform the keystone correction function. When a height is not correct for a front projection, the screen may be distorted up or down. The keystone correction function may be a function of correcting a distorted screen. For example, in case that the distortion occurs on the screen in a horizontal direction, the distortion may be corrected using a horizontal keystone, and in case that the distortion occurs on the screen in a vertical direction, the distortion may be corrected using a vertical keystone. The quick corner (or four corner) keystone correction function may be a function of correcting the screen in case that a balance between corner areas of the screen is not appropriate while a central area of the screen is normal. The lens shift function may be a function of moving the screen as it is in case that the screen is outside a screen area.
The projecting part 112 may provide the zoom/keystone/focusing functions by automatically analyzing a surrounding environment and a projection environment without the user input. The projecting part 112 may automatically provide the zoom/keystone/focusing functions, based on the distance between an electronic apparatus 100 and the screen, information about a space where the electronic apparatus 100 is currently positioned, information about an amount of ambient light, or the like, detected by the sensor (e.g., depth camera, distance sensor, infrared sensor, or illumination sensor).
In addition, the projecting part 112 may provide an illumination function by using the light source. In particular, the projecting part 112 may provide the illumination function by outputting the light source by using the LED. In various embodiments, the projecting part 112 may include one LED, and in various embodiments, the electronic apparatus 100 may include the plurality of LEDs. The projecting part 112 may output the light source by using a surface-emitting LED in an implementation example. The surface-emitting LED may be an LED in which an optical sheet is disposed on an upper side of the LED for the light source to be evenly dispersed and output. When the light source being output through the LED, the light source may be evenly dispersed through the optical sheet, and the light source dispersed through the optical sheet may be introduced into a display panel.
The projecting part 112 may provide the user with a dimming function for adjusting intensity of the light source. The projecting part 112 may control the LED to output the intensity of the light source that corresponds to a received user input when receiving the user input for adjusting the intensity of the light source from the user through the manipulation interface 115 (e.g., touch display button or dial).
In addition, the projecting part 112 may provide the dimming function, based on the content analyzed by the processor 111 without the user input. The projecting part 112 may control the LED to output the intensity of the light source, based on information (e.g., content type or content brightness) on the currently-provided content.
The projecting part 112 may control a color temperature by the control of the processor 111. The processor 111 may control a color temperature based on the content. In case that it is identified that the content is to be output, the processor 111 may obtain color information for each frame of the content whose output is determined. The processor 111 may then control the color temperature based on the obtained color information for each frame. The processor 111 may obtain at least one main color of the frame based on the color information for each frame. The processor 111 may then adjust the color temperature based on the obtained at least one main color. For example, the color temperature that the processor 111 may adjust may be divided into a warm type or a cold type. The frame to be output (hereinafter, output frame) may include a fire scene. The processor 111 may identify (or obtain) that the main color is red based on the color information included in the current output frame. The processor 111 may then identify the color temperature corresponding to the identified main color (red). The color temperature corresponding to the red color may be the warm type. The processor 111 may use an artificial intelligence model to obtain the color information or main color of the frame. According to an embodiment of the disclosure, the artificial intelligence model may be stored in the electronic apparatus 100 (e.g., memory 113). According to an embodiment of the disclosure, the artificial intelligence model may be stored in an external server capable to communicate with the electronic apparatus 100.

Here, the processor 111 may control the driving part 120 to protrude the projecting part 112 from the main body 103.
In detail, referring to
In addition, the processor 111 may identify whether the protrusion distance of the projecting part 112 that corresponds to the projection plane matches a pre-protrusion distance of the projecting part 112 from the main body 103 (S730).
In case that the pre-protrusion distance of the projecting part 112 from the main body 103 matches the protrusion distance of the projecting part 112 that corresponds to the projection plane (S730-Y), the processor 111 may control the projecting part 112 for the projecting part 112 to project the image on the projection plane while maintaining the pre-protrusion distance from the main body 103 (S740).
In addition, in case that the pre-protrusion distance of the projecting part 112 from the main body 103 and the protrusion distance of the projecting part 112 that corresponds to the projection plane are different from each other (S730-N), the processor 111 may protrude the projecting part 112 to the protrusion distance corresponding to the projection plane. That is, the processor 111 may protrude the projecting part 112 for the protrusion distance of the projecting part 112 to be the protrusion distance corresponding to the projection plane (S750).
In addition, in case that the projecting part 112 protrudes by the protrusion distance corresponding to the projection plane, the processor 111 may control the projecting part 112 to project the image on the projection plane (S760).
Meanwhile, according to an embodiment of the disclosure, the processor 111 may protrude the projecting part 112 through the plurality of paths.
In detail, the processor 111 may protrude the projecting part 112 through the first path or the second path. Here, the first path may be the path in which the projecting part 112 is moved in the direction parallel to the ground where the electronic apparatus 100 is positioned. In addition, the second path may be the path in which the projecting part 112 is moved in the vertical or diagonal direction from the ground where the electronic apparatus 100 is positioned.
That is, the processor 111 may protrude the projecting part 112 in a first direction, or protrude the projecting part 112 in a second direction. Here, the first direction may indicate the direction parallel to the ground where the electronic apparatus 100 is positioned, and the second direction may be the vertical or diagonal direction from the ground where the electronic apparatus 100 is positioned.
Here, the processor 111 may protrude the projecting part 112 along the first path in case that the protrusion distance of the projecting part 112 is less than a predetermined distance. In addition, the processor 111 may protrude the projecting part 112 along the second path in case that the protrusion distance of the projecting part 112 is the predetermined distance or more.
For example, as shown in
In addition, the processor 111 may identify the protrusion distance of the projecting part 112 that corresponds to the projection plane based on the information on the projection plane 20. For example, the processor 111 may identify the protrusion distance of the projecting part 112 as 50 cm. In addition, the predetermined distance may be 30 cm.
Here, the processor 111 may protrude the projecting part 112 along the first path (a movement path in an y-axis direction). Here, the first path may indicate a direction horizontal to a ground 40.
Here, as shown in
In addition, in case that the projecting part 112 protrudes by the predetermined distance of 30 cm, the processor 111 may protrude the projecting part 112 along the second path (a movement path in a z-axis direction or the z-axis and y-axis directions). Here, the second path could be the path that gets further away from the ground 40.

Alternatively, as shown in
Alternatively, as shown in
As described above, in case that the projecting part 112 protrudes by the predetermined distance, the electronic apparatus 100 may protrude the projecting part 112 in the vertical, diagonal or curved direction from the ground, thereby reducing a horizontal distance by which the projecting part 112 protrudes from the main body (that is, the protrusion distance of the projecting part 112 in the y-axis direction shown in
Meanwhile, according to an embodiment of the disclosure, the electronic apparatus 100 may project the image on the projection plane and the screen 106.
In detail, the processor 111 may project the image on the projection plane 20.
Here, the processor 111 may control the driving part 120 to rotate the screen 106 in case that the operation mode of the electronic apparatus 100 is the mode for displaying the content on the projection plane. In detail, the processor 111 may rotate the screen 106 by 90 degrees while the projection plane of the screen 106 is in contact with one surface (e.g., upper surface) of the main body 103.
Alternatively, the processor 111 may rotate the screen 106 for displaying the image information in case of obtaining a user command for displaying the image information while the image is projected on the projection plane.
For example, as shown in
Meanwhile, the image information projected on the screen 106 may be different based on a type of the image projected on the projection plane 20. For example, in case that the image projected on the projection plane 20 is the sports image, the image projected on the screen 106 may be the sports score status. Alternatively, in case that the image projected on the projection plane 20 is news, the image projected on the screen 106 may be a headline or weather. Alternatively, in case that the image projected on the projection plane 20 is a music program, the image projected on the screen 106 may be a song title or song lyrics. Alternatively, in case that the image projected on the projection plane 20 is a game, the image projected on the screen 106 may be a game score. Alternatively, in case that the image projected on the projection plane 20 is a video, the image projected on the screen 106 may be a playback progress bar.
Meanwhile, according to an embodiment of the disclosure, the screen 106 may be the rollable screen that may be retracted in the main body 103 and protrude to the top of the main body 103.
Accordingly, in case that the operation mode of the electronic apparatus 100 is the mode for displaying the content on the projection plane, the processor 111 may control the driving part 120 to protrude the screen 106 to the top of the main body 103. Alternatively, the processor 111 may control the driving part 120 to protrude the screen 106 to the top of the main body 103 in case of obtaining the user command for displaying the image information while the image is projected on the projection plane.
In case that the screen 106 protrudes to the top of the main body 103, the processor 111 may project the image information projected on the projection plane to the screen 106.

In addition, the processor 111 may control the projecting part 112 to project the image on the projection plane while having the identified luminance value.
According to the above-described method, the electronic apparatus 100 of the disclosure may project the image having a constant luminance value even in case that the protrusion distance of the projecting part 112 is changed.
