The projection part 112 is a component that projects an image to the outside. The projection part 112 according to the one or more embodiments of the disclosure may be implemented in various projection types (e.g., a cathode-ray tube (CRT) type, a liquid crystal display (LCD) type, a digital light processing (DLP) type, a laser type, etc.). As an example, the CRT method has basically the same principle as a CRT monitor. In the CRT method, an image is enlarged to a lens in front of a cathode-ray tube (CRT), and the image is displayed on a screen. According to the number of cathode-ray tubes, the CRT method is divided into an one-tube method and a three-tube method, and in the case of the three-tube method, the method may be implemented while cathode-ray tubes of red, green, and blue colors are separated from one another.
As another example, the LCD method is a method of displaying an image by making a light output from a light source pass through a liquid crystal display. The LCD method is divided into a single-plate method and a three-plate method, and in the case of the three-plate method, a light output from a light source may be divided into red, green, and blue colors in a dichroic mirror (a mirror that reflects only lights of specific colors, and makes the rest pass through), and pass through a liquid crystal display, and then the lights may be gathered in one place.
As still another example, the DLP method is a method of displaying an image by using a digital micromirror device (DMD) chip. A projection part by the DLP method may include a light source, a color wheel, a DMD chip, a projection lens, etc. A light output from the light source may show a color as it passes through the rotating color wheel. The light that passed through the color wheel is input into the DMD chip. The DMD chip includes numerous micromirrors, and reflects the light input into the DMD chip. The projection lens may perform a role of enlarging the light reflected from the DMD chip to an image size.
As still another example, the laser method includes a diode pumped solid state (DPSS) laser and a galvanometer. As lasers outputting various colors, lasers wherein three DPSS lasers are installed for each of R, G, and B colors, and then their optical axes are overlapped by using a special mirror are used. The galvanometer includes a mirror and a motor of a high output, and moves the mirror at a fast speed. For example, the galvanometer may rotate the mirror at 40 KHz/sec at the maximum. The galvanometer is mounted according to a scanning direction, and in general, a projector performs plane scanning, and thus the galvanometer may also be arranged while being divided into x and y axes.
The projection part 112 may include light sources of various types. For example, the projection part 112 may include at least one light source among a lamp, light emitting diodes (LEDs), and a laser.
The projection part 112 may output an image in a screen ratio of 4:3, a screen ratio of 5:4, and a wide screen ratio of 16:9 according to the use of the electronic device 100 or the user's setting, etc., and 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), Full HD (1920*1080), etc. according to screen ratios.
The projection part 112 may perform various functions for adjusting an output image by control by the processor 111. For example, the projection part 112 may perform functions such as zoom, keystone, quick corner (four corner) keystone, lens shift, etc.
For example, the projection part 112 may enlarge or reduce an image according to its distance (i.e., a projection distance) to the screen. That is, a zoom function may be performed according to the distance to the screen. Here, 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 an image, or the like. When the zoom function is performed, it is necessary to adjust a focus of an image. For example, a method of adjusting a focus includes a manual focusing method, an electric focusing method, etc. The manual focusing method may be a method of manually adjusting the focus, and the electric focusing method may be a method in which a projector automatically adjusts the focus by using a built-in motor when the zoom function is performed. When performing the zoom function, the projection part 112 may provide a digital zoom function through software, and may provide an optical zoom function in which the zoom function is performed by moving the lens through the driver 120.
In addition, the projection part 112 may perform a keystone correction function. When a height does not match 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, when a distortion of an image occurs in a left-right direction of the screen, the screen may be corrected by using a horizontal keystone, and when a distortion of an image occurs in an up-down direction, the screen may be corrected by using a vertical keystone. The quick corner (four corner) keystone correction function is a function of correcting a screen in case the central area of the screen is normal but the corner areas are out of balance. The lens shift function is a function of moving a screen as it is in case the screen is outside a screen area.
The projection part 112 may provide the zoom/keystone/focusing functions by automatically analyzing a surrounding environment and a projection environment without a user input. For example, the projection part 112 may automatically provide the zoom/keystone/focusing functions based on the distance between the electronic device 100 and the screen, information about a space where the electronic device 100 is currently positioned, information about an amount of ambient light, etc. detected through a sensor (e.g., a depth camera, a distance sensor, an infrared sensor, an illumination sensor, etc.).

In particular, the projection part 112 may provide the illumination function by outputting a light source by using LEDs. According to one or more embodiments, the projection part 112 may include one LED. According to another embodiment, the electronic device 100 may include a plurality of LEDs. The projection part 112 may output a light source by using a surface emitting LED depending on implementation examples. Here, a surface emitting LED may be an LED having a structure wherein an optical sheet is arranged on the upper side of the LED such that a light source is evenly dispersed and output. For example, when a light source is output through an LED, the light source may be evenly dispersed through an optical sheet, and the light source dispersed through the optical sheet may be incident on a display panel.
The projection part 112 may provide a dimming function for adjusting the intensity of a light source to the user. For example, when a user input for adjusting the intensity of a light source is received from the user through the manipulation interface 115 (e.g., a touch display button or a dial), the projection part 112 may control the LED to output the intensity of the light source that corresponds to the received user input.
In addition, the projection part 112 may provide the dimming function based on a content analyzed by the processor 111 without a user input. In addition, the projection part 112 may control the LED to output the intensity of a light source based on information on a content that is currently provided (e.g., the content type, the content brightness, etc.).
The projection part 112 may control a color temperature by control by the processor 111. Here, the processor 111 may control a color temperature based on a content. For example, when it is identified that a content is to be output, the processor 111 may obtain color information for each frame of the content of which output has been determined. Then, the processor 111 may control the color temperature based on the obtained color information for each frame. Here, the processor 111 may obtain at least one main color of the frame based on the color information for each frame. Then, the processor 111 may adjust the color temperature based on the obtained at least one main color.

The processor 111 may identify (or obtain) that the main color is red based on the color information included in the current output frame. Then, the processor 111 may identify the color temperature corresponding to the identified main color (red). Here, the color temperature corresponding to the red color may be the warm type.

The control method may further include the steps of obtaining first metadata corresponding to the first content 11 and second metadata corresponding to the second content 12, obtaining the first luminance value based on the first metadata, and obtaining the second luminance value based on the second metadata.
In the step of obtaining the first luminance value, based on the first luminance value not being obtained on the basis of the first metadata, the first luminance value may be obtained based on an average pixel value of a plurality of frames included in the first content 11, and in the step of obtaining the second luminance value, based on the second luminance value not being obtained on the basis of the second metadata, the second luminance value may be obtained based on an average pixel value of a plurality of frames included in the second content 12.
In the step of obtaining the first luminance value, based on the first luminance value not being obtained on the basis of the first metadata, an image including the first content 11 projected on a projection surface 10 may be obtained, and the first luminance value may be obtained on the basis of the obtained image, and in the step of obtaining the second luminance value, based on the second luminance value not being obtained on the basis of the second metadata, an image including the second content 12 projected on the projection surface 10 may be obtained, and the second luminance value may be obtained on the basis of the obtained image.
In the operation S5015 of projecting the first content 11, the first content 11 may be projected on a first area corresponding to the first position information by controlling a projection angle.
The control method may further include the step of, based on identifying that the first content 11 may not be projected on the first area corresponding to the first position information by controlling the projection angle, controlling a moving element included in the electronic device to project the first content 11 on an area corresponding to the first position information.
The control method may further include the step of, based on identifying that the first content 11 may not be projected on the first area corresponding to the first position information by controlling the projection angle, changing the size of the first content 11, and in the operation S5015 of projecting the first content 11, the changed first content may be projected on the first area corresponding to the first position information.
The control method may further include the step of, based on the difference value being greater than or equal to a threshold luminance value, changing at least one of the first luminance value or the second luminance value, and in the operation S5015 of projecting the first content 11, based on the first luminance value being changed, the first content 11 may be projected based on the changed first luminance value, and in the operation S5020 of transmitting a control signal to the external device, based on the second luminance value being changed, a control signal for projecting the second content 12 based on the changed second luminance value may be transmitted to the external device.
The control method may further include the steps of obtaining first power information for a battery of the electronic device, obtaining second power information for a battery of the external device, and based on the first power information being smaller than a threshold power value, and the second power information being greater than or equal to the threshold power value, comparing the first luminance value and the second luminance value, and based on the first luminance value exceeding the second luminance value, projecting a guide user interface (UI) for projecting the first content 11 from the external device and projecting the second content 12 from the electronic device, and based on receiving a user input through the guide UI, projecting the second content 12 based on the second position information, and transmitting a control signal for projecting the first content 11 based on the first position information to the external device.
