Image processing device and image processing method

Abstract

An image processing device includes signal processors, a second-control-signal generator that generates second control signals in accordance with first control signals generated by the signal processors, and an image synthesizer. Each signal processor includes a first digital processor for performing image adjustment and a second digital processor. The second digital processor includes a defect detector that detects a defective pixel and a defective pixel adaptation processor that generates, in accordance with the result of defective pixel detection, the first control signal specifying a synthesis coefficient to the second-control-signal generator. In accordance with synthesis coefficients indicated by the second control signals, the image synthesizer synthesizes images that have undergone the image adjustment by the first digital processors of the signal processors. When the defective pixel is detected, the defective pixel adaptation processor generates the first control signal for enabling the images to include an image in which the defective pixel remains.
