Semiconductor device, image processing system, image processing method and computer readable storage medium

A semiconductor device for synthesizing first and second captured image data each including captured image data of an overlapping region, the first captured image data being data obtained by capturing an image of a first image capturing region, the second captured image data being data obtained by capturing an image of a second image capturing region, the overlapping region being a region where the first and second image capturing regions overlap each other, the semiconductor comprising:

• an image data acquisition circuit configured to acquire the first and second captured image data on which initial color adjustment processing has been performed;
• an estimation source image generation circuit configured to cancel effects of the initial color adjustment processing performed on the first captured image data and the second captured image data to generate image data of a first estimation source image and image data of a second estimation source image;
• a readjustment circuit configured to divide each of the first estimation source image and the second estimation source image into a plurality of processing region, and perform color balance readjustment processing on each of the image data of the first estimation source image and the image data of the second estimation source image for each processing region;
• and
• an image synthesis circuit configured to synthesize the image data of the first estimation source image and the image data of the second estimation source image so that a region associated with the overlapping region included in the first estimation source image and a region associated with the overlapping region included in the second estimation source image overlap each other to generate image data of a synthesized image.
