IMAGE PROCESSING DEVICE AND CAMERA SYSTEM

WIPO Patent Application WO/2011/021345

A1

Disclosed is an image processing device capable of avoiding excess of the amount of code even in a case where excess of the amount of code would have occurred. Specifically disclosed is an image processing device (110) which comprises an image processing circuit (103) that generates brightness data and color difference data of images; a compression processing circuit (105) that acquires the generated brightness data and the color difference data as input images, sets an compression ratio, and performs encoding including quantization on the input images in accordance with the set compression ratio; and a control processing circuit (106) that acquires at least one of compression process information and image information generated at the compression processing circuit (105) during the last encoding from the compression processing circuit (105), performs at least one of compression state determination regarding the compression state during encoding, scene change determination regarding whether or not a scene change occurs in the input images, and scene complexity determination regarding the complexity of the input images, and sets quantization parameters for the next encoding at the compression processing circuit (105) on the basis of the determination result.
