DISPLAY BRIGHTNESS ADJUSTMENT METHOD AND RELATED APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17917392 titled 'DISPLAY BRIGHTNESS ADJUSTMENT METHOD AND RELATED APPARATUS
Simplified Explanation
The patent application describes a method for adjusting the display brightness of an electronic device based on the average pixel level (APL) of the image being displayed. This ensures that the contrast is maintained when the brightness is turned down at a low APL, while also ensuring a high contrast effect for HDR displays.
- The electronic device obtains the image to be displayed and calculates the APL of the image.
- Based on a third light adjustment curve, the device determines the actual display brightness value corresponding to the APL of the image.
- The device then adjusts the display brightness of the image based on the actual display brightness value.
Potential applications of this technology:
- Mobile devices: This method can be implemented in smartphones and tablets to automatically adjust the display brightness based on the content being viewed, providing a better viewing experience.
- Televisions: HDR displays are becoming increasingly popular in televisions, and this method can ensure that the image brightness maintains a high contrast effect while adjusting the brightness based on the content.
Problems solved by this technology:
- Maintaining contrast: By adjusting the display brightness based on the APL of the image, this method ensures that the contrast is not compromised when the brightness is turned down at a low APL.
- High contrast effect: For HDR displays, this method ensures that the image brightness maintains a high contrast effect, enhancing the viewing experience.
Benefits of this technology:
- Improved viewing experience: By automatically adjusting the display brightness based on the content, this method provides a more comfortable and visually appealing viewing experience.
- Energy efficiency: By dynamically adjusting the display brightness, this method can help conserve battery life in mobile devices and reduce power consumption in televisions.
Original Abstract Submitted
This application discloses a display brightness adjustment method, including: an electronic apparatus obtains a to-be-displayed image and calculates an average pixel level APL of the to-be-displayed image. The electronic apparatus determines, based on the third light adjustment curve, an actual display brightness value corresponding to the average pixel level of the to-be-displayed image. The electronic apparatus adjusts display brightness of the to-be-displayed image based on the actual display brightness value. In this way, impact exerted on contrast when brightness is turned down at a low APL can be ensured, and a high contrast effect of image brightness of an HDR display can be ensured.
