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.
Meanwhile, 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.

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. Meanwhile, 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 mean a method of manually adjusting the focus, and the electric focusing method may mean 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 means a function of correcting a distorted screen. For example, if 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 if 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.

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.).
Meanwhile, 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.
