Signal processing apparatus, signal processing method, program and recording medium

A signal processing method comprising the steps of:

• receiving a first image generated by a first camera that captures a subject included in a predetermined range at a first angle of view, and receiving 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;
• detecting a similar portion between part of the subject included in the first image and a subject included in each of the second images;
• pasting the second images at positions corresponding to the detected similar portions within the first image to generate a synthesized image;
• detecting 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
• changing 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.

A program for causing a computer to execute a process comprising the steps of:

• receiving a first image generated by a first camera that captures a subject included in a predetermined range at a first angle of view, and receiving 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;
• detecting a similar portion between part of the subject included in the first image and a subject included in each of the second images;
• pasting the second images at positions corresponding to the detected similar portions within the first image to generate a synthesized image;
• detecting 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
• changing 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.
