  • Patent number: 10574961
    Abstract: Disclosed is an image processing apparatus and a control method thereof that can correct the brightness of a pixel in an image. Reflection characteristics of environment light when the image is captured are estimated by applying smoothing to the image. The brightness of the pixel is corrected by computing a correction value for correcting the brightness of the pixel based on the reflection characteristics of the environment light and adding the correction value to the pixel. The brightness can be corrected while suppressing an amplification of noise and a loss of details of a subject.

  • Patent number: 10440339
    Abstract: A reflection correction processing unit extracts at least color information from a peripheral area of a processing target pixel having a high luminance in an input image, and performs control, to the processing target pixel, to reduce the luminance of the processing target pixel and to bring a chrominance signal of the processing target pixel close to a predetermined chrominance signal ratio. In a case where a chrominance signal ratio based on the color information is close to the predetermined chrominance signal ratio, the reflection correction processing unit increases an intensity of the correction to the processing target pixel.
