The invention discloses a method and device for determining and adjusting backlight brightness, a storage medium and electronic equipment, which are applied to medical displays and relate to the technical field of display. The backlight brightness determination method includes: acquiring a period of a dimming signal used to adjust a backlight brightness signal and a plurality of integration time periods; wherein, the integration time period does not exceed the period of the dimming signal at most; determining the Multiple integration starting points with the same phase on the dimming signal; according to the multiple integration starting points and the multiple integration time periods, the backlight brightness signal is successively integrated for multiple times, and the multiple integrations are integrated. The result is determined as a plurality of candidate luminances; the maximum luminance among the plurality of candidate luminances is determined as the backlight luminance. The present disclosure can accurately determine the backlight brightness.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular, to a method for determining backlight brightness of a medical display, a device for determining backlight brightness of a medical display, a method for adjusting backlight brightness of a medical display, a device for adjusting backlight brightness of a medical display, a storage medium and an electronic device. equipment. Background technique [0002] With the development of display technology and increasingly demanding social needs, accurate and stable LCD screen backlight brightness has become a basic requirement for display, especially in scenarios such as medical display, it is necessary to ensure accurate display of medical-grade images. [0003] On the one hand, the backlight of the display will age with long-term use, causing the brightness of the display to decay over time; on the other hand, the backlight of the display will also be affected by changes in the am...
