Brightness sensing obtains the corresponding ambient color temperature. In an embodiment of the invention, the color temperature sensing module 110 can include a photographic element 115 (or a network photographic element), and the photographic element 115 can be used to acquire an environmental image and process the acquired environmental image. To obtain the corresponding ambient color temperature. In practice, the photographic element 115 can be a webcam or other imaging component that is commonly found on computer or portable devices. The network camera generally has the basic functions of video photography/propagation and still image capture. After the image is captured by the lens, the image can be processed and converted into a computer by the photosensitive element circuit and the control component in the network camera. The digital signal that can be recognized is then input to the computer through the transmission interface, and then the image is restored by the software. Therefore, the user can obtain the brightness of the surrounding light with time or weather through the instant image sensing process through a webcam or other camera component commonly used in a general computer or a portable device. Corresponding ambient color temperature. The color temperature determination module 120 is coupled to the color temperature sensing module 110 and configured to obtain a corresponding one of the display color values according to the ambient color temperature calculation obtained by the sensing. In an embodiment of the invention, the color temperature determination module 120 can be a processor (eg, a central processing unit, a microprocessor, etc.), and the processor processes the induced ambient color temperature and obtains the calculated color temperature. The corresponding display color value is used for subsequent processing, so that the ambient color temperature can be calculated by the processor set in the general computer or the portable device, and the corresponding display color value can be obtained. The display module 130 is coupled to the color temperature determination module 120 and has a current display color temperature when the image is displayed. In practice, the display module 130 can be implemented by different types of displays such as a liquid crystal display, a plasma display, an organic light emitting display, etc. in 201223294. When the brightness of the ambient environment changes with time or weather, the display module 130 displays the color value according to the above calculation in the state of displaying the image, and has the current display. The color temperature is adjusted to have a relative display color temperature. In an embodiment of the invention, the display color value calculated by the color temperature determination module 120 may be a white balance value or a gamma correction value, and the display module 130 is based on the white balance value or The gamma correction value performs white balance processing or gamma correction processing on the displayed image signal, so that when the brightness of the surrounding environment changes, the display module 130 can automatically adjust the displayed image display color temperature according to the change of the ambient color temperature.

[s] 8 201223294 FIG. 2 is a flow chart showing a method of automatically adjusting the display color temperature according to an embodiment of the invention. It should be noted that the steps mentioned in this embodiment can be adjusted according to actual needs, except for the order of the sequence, and can be performed simultaneously or partially simultaneously. The process shown in FIG. The drawings are only one embodiment and are not intended to limit the invention. First, an ambient color temperature is obtained by sensing the surrounding environment (step S202), that is, regardless of whether the location is indoors or outdoors, the brightness of the ambient light in the room or outdoors is first sensed to obtain the corresponding ambient color temperature. This step S202 can be performed by a photographic element, which in practice can be a network camera or other imaging element commonly found on a computer or a portable device. In another embodiment of the present invention, the step S202 of obtaining the ambient color temperature by the sensing may further comprise: first acquiring an environmental image, and then performing image processing on the environmental image, thereby obtaining an ambient color temperature. Similarly, the above-described steps of obtaining an environmental image and then performing image processing to obtain an ambient color temperature can be performed by a webcam or other imaging element commonly used in a computer or a portable device. After step S202, a corresponding one of the display color values is obtained according to the obtained ambient color temperature calculation (step S204), wherein the step S204 can be set by a processor (eg, a general computer or a portable device) The central processor, microprocessor, etc.) to execute. In an embodiment of the invention, the display color value may be a white balance value or a gamma correction value. Then, according to the calculated display color value, a current display color temperature is adjusted to a relative display color temperature (step S206), wherein the current display 201223294 color temperature and the relative display color temperature can be a liquid crystal display, a plasma display, an organic light emitting display. .. display color temperature of images displayed by different forms of display.

Or gamma correction value), and then image processing the displayed image according to the displayed color value (such as white balance processing or gamma correction processing), so that the current display color temperature of the displayed image can be automatically adjusted to the relative display accordingly. The color temperature is used to make the displayed image more in line with the user's actual viewing needs. In the case of an electronic device generally having a display, the display color temperature of the display is usually set to a preset value only at the time of production and shipment, and then the display is displayed by the preset display color temperature, and the display cannot be displayed on the image. The process is adjusted according to the conditions of the environment. In addition, even if the person skilled in the art has proposed many related technologies for adjusting the color temperature of the display, most of them are limited to the color temperature setting process performed by the display at the time of production and shipment; in other words, the color temperature of the display is still not available to the user during actual operation or It is an automatic adjustment during the process of viewing images, which is not conducive to the actual needs of users. In contrast, the application of the aforementioned electronic device with automatic color temperature adjustment mechanism and the method of automatically adjusting the display color temperature not only allows the color temperature of the display device to be adjusted during the image display process, but also automatically adjusts according to the condition of the environment, so that The picture viewed by the user is more in line with the current color of the surrounding environment, and more in line with the needs of the human eye. 201223294 The present invention has been disclosed in the above embodiments, but it is not intended to limit the invention, and any person skilled in the art can make various changes and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
