  • Computer implemented method for temporally stabilizing white point information in an auto white balance process, a data processing apparatus, a computer program product, and a computer-readable storage medium
    Patent number: 11457191
    Abstract: A method, apparatus, and a non-transitory computer-readable storage medium for temporally stabilizing White Point (WP) information in an Auto White Balance (AWB) process. The method may include receiving lux level, AWB statistics, and input WP. The method also include generating a histogram of the AWB statistics. The method may also include generating, from the histogram, a confidence value for the input WP. The method may also include determining a major colour count. The method may also include determining a threshold value based on the major colour count and the lux level. The method may also include setting an update state to locked when the confidence value is below the threshold value and otherwise setting it to unlocked. The final WP information is obtained from a previous frame when the update state is locked and otherwise from the input WP information.
