  • Patent number: 11145240
    Abstract: A method for dynamic scaling of content luminance and backlight level includes determining, using one or more processors of a display system, an ambient light level of a local environment proximate the display system. Based on the ambient light level being brighter than a first ambient light threshold, it is determined that the display system is in a normal room or a bright environment. A minimum viewable threshold representing a minimum pixel luminance value perceivable by a user in the ambient light level of the local environment is determined. The method further includes generating a modified display image by shifting the pixel luminance values of one or more pixels of an input image such that a darkest pixel value of the modified display image is equal to or greater than the minimum viewable threshold before transmitting the modified display image for display.

  • Patent number: 10923059
    Abstract: An operation method of a display device with high visibility is to be provided. The display device is an electronic device including a first display element, a second display element, an optical sensor, and a gain calculation circuit. In the electronic device, the illuminance of external light is obtained with the optical sensor, and depending on the illuminance, images displayed using the first display element and the second display element are corrected. The gain calculation circuit obtains the illuminance and calculates a gain value depending on the illuminance. In particular, the gain value is calculated for each of the first display element and the second display element. Furthermore, the gain calculation circuit performs dimming and toning on image data displayed using the first display element and the second display element by multiplying the image data by the gain values or values corresponding to the gain values.
