Screen brightness analysis system and method connected with imaging brightness meter and illuminometer

By integrating an imaging luminance meter and an illuminance meter into a screen brightness analysis system, the correlation between screen brightness and ambient illuminance on the physiological effects on the human eye is quantified. This solves the problem of insufficient correlation between photometric parameters and visual health in existing technologies, and enables quantitative assessment of visual fatigue risk and health assessment.

Abstract

The invention discloses a screen brightness analysis system and method connected with an imaging brightness meter and an illuminometer. The system comprises a screen brightness data transmission module for receiving screen brightness measured by an imaging brightness meter; the illumination environment illumination data transmission module is used for receiving the illumination environment illumination measured by the illuminometer; and the screen brightness human eye physiological effect parameter calculation module is used for receiving the screen brightness transmitted by the screen brightness data transmission module and the illumination environment illumination transmitted by the illumination environment illumination data transmission module, and calculating the human eye physiological effect parameter according to the received screen brightness, illumination environment illumination and the like. According to the invention, when the user uses the imaging brightness meter to measure the screen brightness and uses the illuminometer to measure the illumination environment illumination, the physiological effect of the screen brightness can be synchronously calculated, and the risk of asthenopia caused by the screen brightness can be evaluated, so that the user can adjust the eyes in time.
