Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, PROGRAM, AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/017081
Kind Code:
A1
Abstract:
A signal processing unit 30 performs pre-processing, demosaic processing, color reproduction processing, etc. on an image signal generated by an imaging unit 22. A control unit 55 uses the image signal before undergoing reproduction processing and the image signal having undergone the color reproduction processing, to detect an image region in which a characteristic change has exceeded a prescribed amount of change. In addition, a display unit 43 performs image display on the basis of the image signal having undergone the color reproduction processing, whereas the control unit 55 makes it possible to identify an image region, in the image displayed by the display unit 43, where color reproduction processing exceeding the prescribed amount of change has been performed. The control unit 55 further associates, with the image signal having undergone the color reproduction processing, region information indicating the detection result of the image region in which the characteristic change has exceeded the prescribed amount of change, and then causes a recording unit 41 to record said region information on a recording medium, or causes a signal output unit 42 to output said region information to an external device. Thus, the present invention enables detection of an image region which exhibits an unnatural control change resulting from the color reproduction processing.
