发明名称 IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND IMAGE PICKUP APPARATUS
摘要 There are provided an image processing apparatus and method capable of providing a good image whose overexposure and underexposure are suppressed by holding information about saturation and contrast at the time of performing a dynamic range compression. In the image processing apparatus, a level information calculating circuit calculates the level information of each pixel from R, G and B image signals for each pixel, a gain calculating circuit refers to a gain table based on the level information of each pixel calculated by the level information calculating circuit and calculates a gain by which the R, G and B signals of each pixel are multiplied, and a multiplying circuits multiply the R, G and B signals by the gain.
