Information terminal

Abstract

The embodiment of the invention relates to an information terminal. The information terminal comprises a display screen, a camera, a photo detecting and imaging unit, a photo grayscale analyzing unit,an output unit, a display screen parameter adjusting unit and a background illuminating lamp parameter adjusting unit; the photo detecting and imaging unit is used for converting the photo analog signals acquired by the camera into digital photo data; the photo grayscale analysis unit is used for performing gray analysis on the photo data to generate a state parameter of a background environmentof a user visual angle range; the background illuminating lamp parameter adjusting unit generates a control signal according to the state parameters and outputs the control signal to an external lighting device through the output unit, so that the lighting parameters of the external lighting device can be adjusted, and the lighting state of the background environment can reach the preset parameters; the display screen parameter adjusting unit is used for adjusting display parameters of the display screen based on the preset corresponding relation according to the state parameters, so that thedisplay parameters of the display screen are matched with the lighting state of the background environment in the visual angle range of the user.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an information terminal. Background technique [0002] Today, with the development of Internet electronic products such as mobile phones and tablets, more and more people stare at video terminals such as mobile phones for a long time, causing visual fatigue of human eyes, which leads to vision loss and affects visual health. [0003] At present, most smartphones come with an automatic brightness adjustment mode. The brightness sensor located near the earpiece recognizes the surrounding light environment to detect the brightness of the surrounding environment, and then calculates the brightness of the screen display according to a preset algorithm. [0004] However, users often still encounter the situation that the display of screen brightness in this automatic adjustment method does not conform to their own visual perception during use. This is due to the error between the brig...

Problems solved by technology

[0004] However, users often encounter the situation that the display of screen brightness in this automatic adjustment method does not conform to their own visual perception during use. Only caused by the limitation of adjusting the brightness

At the same time, for scenes with relatively dark ambient brightness, even if the brightness of the display screen is adjusted, it still cannot fully adapt to the brightness of the surrounding environment and at the same time take into account the normal visualization needs of users.

At present, there is no good way to solve the above problems in the industry.
