Light environment adaptive regulating system for screen display equipment

Abstract

The invention discloses a light environment adaptive regulating system for screen display equipment. The adopted technical scheme is as follows: screen display parameters are adjusted according to a video signal source and a surrounding light environment: an optical sensing system acquires an optical signal in the environment in which the screen display equipment is located according to a certain time frequency and then transmits the signal to a threshold judgment unit in real time; the threshold judgment unit calculates the difference between ambient light parameters before and after two-time optical signal acquisition and compares the difference with a preset threshold; if the selected parameter exceeds the preset threshold, the display signal sent by the screen display signal source is processed so that a display terminal works to display the brightness, contrast ratio, color, saturation degree and font size of screen information which is adjusted in real time so as to reduce and even eliminate the influence on visual identification caused by the change of ambient light; and if the difference between the optical signal parameters is less than the preset threshold, the original screen display signal is not processed. The light environment adaptive regulating system can be widely applied to a visual display terminal in the case of change of the light environment.

Description

technical field [0001] The invention belongs to the field of screen display control equipment manufacturing. Background technique [0002] In production operations and daily life, people often come into contact with various display devices. Changes in the brightness and color of the ambient light can easily interfere with the display parameters of the display device, reduce the readability of the display content, distort the information display, bring inconvenience to the operation and even cause misoperation. The greater the change value of the ambient light signal, the more difficult it is for the human eye to read and process the displayed information. Therefore, a set of screen display device light environment adaptive system is designed to adjust the display parameters of the screen display device when the external light environment changes, so that the visual recognition efficiency can be restored to the level before the change, thereby reducing or even eliminating th...

Problems solved by technology

This method is limited to the adjustment of brightness and contrast, and does not consider factors that affect visual recognition such as color saturation and font size, nor does it consider the interaction between human eyes, ambient light, and screen display.
