Problems solved by technology

[0005] Although the image can be adjusted to the optimum state according to the brightness and color temperature of the environment, it is difficult to obtain a high-quality image because this adjustment is realized with a look-up table
In particular, this automatic adjustment based on predetermined data does not take into account user preferences or set values, which will lead to differences between adjusted values ​​and actual environmental conditions

Abstract

A device and method for automatically adjusting an image condition in a display is disclosed. The present device and method optimizes the image condition of a display according to individual preferences by taking into account the brightness and color temperature set initially by a user. Particularly, the present invention includes a photo sensor to detect the environmental illumination and a micro processor utilizing the detected data to appropriately adjust the image condition with respect to a user preference.

Description

technical field [0001] The invention relates to a display device, in particular to a device and method for automatically adjusting the image state of a display. The invention automatically adjusts the image state according to the state originally set by the user when the brightness and color temperature around the display change. Background technique [0002] The continuous development of display image state automatic adjustment technology has brought convenient and comfortable visual effects to users. The image automatic adjustment technology can be used in various displays such as televisions, computer monitors, etc., and can be implemented in various forms. For these displays, image states such as brightness, contrast, and color temperature can be automatically adjusted based on ambient illumination and color temperature using pre-built lookup tables. [0003] The look-up table is established from the experimentally obtained image state, ie, the output of the detected c...
