Signal processing circuit and imaging apparatus

An imaging apparatus, comprising:

• a plurality of camera modules;
• and
• a signal processing circuit including
• an image segmentation unit that segments a plurality of photographic images, which are acquired by a plurality of camera modules such that each of the plurality of photographic images includes an overlapping region in a photographic range of each of the plurality of camera modules, into an image of the overlapping region, an image of a direct-transformation region that is a non-overlapping region, and an image of a buffer region provided between the overlapping region and the direct-transformation region, and
• a stitching unit that stitches the images of the overlapping regions, stitches the images of the direct-transformation regions, and stitches the images of the buffer regions, the images of the overlapping regions, the images of the direct-transformation regions, and the images of the buffer regions being segmented by the image segmentation unit.

A signal processing circuit, comprising:

• a storage unit that stores
• a plurality of photographic images, which are acquired by a plurality of camera modules such that each of the plurality of photographic images includes an overlapping region in a photographic range of each of the plurality of camera modules, and
• an image of the overlapping region, which has a resolution higher than a resolution of each of the photographic images;
• a composition-condition estimation unit that estimates the composition condition by the use of the image of the overlapping region;
• and
• a stitching unit that stitches the plurality of photographic images on the basis of the composition condition estimated by the composition-condition estimation unit.
