  • Method and system for adjusting uniformity of image color tones by using a translucent uniformity compensated image layer
    Patent number: 10930243
    Abstract: A method for adjusting uniformity of image color tones includes setting brightness of a darkest display region as target brightness and setting color temperature coordinates of a designated display region as target color temperature coordinates of at least one part of display regions of a display, comparing the brightness and the color temperature coordinates of each display region of the at least one part of display regions with the target brightness and the target color temperature coordinates for generating a first calibrated color tone, generating a second calibrated color tone of the each display region of the at least one part of display regions according to an Alpha channel parameter and the first calibrated color tone, generating a uniformity compensated image layer according to all second calibrated color tones, and virtually overlaying the uniformity compensated image layer on the at least one part of display regions.
