Patent ID: 8077214

Claim:
A signal processing apparatus comprising: an input unit that receives a first image generated by a first camera that captures a subject included in a predetermined range at a first angle of view, and that receives a plurality of second images that are higher in resolution than the first image and generated by a plurality of second cameras, each of which captures part of the subject included in the predetermined range at a second angle of view that is narrower than the first angle of view; a similar portion detecting unit that detects a similar portion between part of the subject included in the first image and a subject included in each of the second images; an image synthesizing unit that pastes the second images at positions corresponding to the detected similar portions within the first image to generate a synthesized image; an imaging area detecting unit that detects an area, for which image information is insufficient in the first image and is difficult to complement by the second cameras, as a non-imageable area from the synthesized image; and a camera parameter calculation unit that changes a camera parameter for controlling the second camera that captures the second image by which the image information insufficient in the first image is complemented.
