Embodiment Construction

[0064] In the following, reference will be made to Figure 1 to Figure 28 Embodiments of the present invention will be described. In this embodiment, an example will be described in which the signal processing device 10 according to the embodiment of the present invention is applied to the image processing system 1 to capture a subject of high contrast ratio in a wide range and then generate high resolution and high Composite image of contrast ratio.

[0065] Configuration example of image processing system 1

[0066] figure 1 A configuration example of the image processing system 1 is shown. The image processing system 1 includes a first camera 2 and second cameras 3a to 3c. The first camera 2 captures a predetermined range from a first viewing angle to generate a first image 5 . The second cameras 3a to 3c photograph parts in the predetermined range at a second angle of view narrower than the first angle of view, and generate second images 6a to 6c. The first image 5 ...

Abstract

The invention discloses a signal processing apparatus, a signal processing method, a program and a recording medium. The signal processing apparatus includes: an input unit receiving a first image generated by a first camera and higher-resolution second images generated by a plurality of second cameras; a similar portion detecting unit detecting a similar portion between part of a subject included in the first image and a subject included in each of the second images; an image synthesizing unit pasting 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 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 a camera parameter calculation unit 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.

Description

technical field [0001] The present invention relates to a signal processing device, a signal processing method, a program, and a recording medium that are suitably applied to, for example, obtaining a wide-range high-contrast ratio image. Background technique [0002] In the prior art, in order to photograph landscapes and the like with a wide angle of view, a panoramic imaging method, a multi-camera imaging method in which multiple cameras are placed in multiple positions, an imaging method in which a low-resolution dynamic image is combined with a high-resolution still image, Multi-focal imaging methods using cameras with multiple focal points, among others. Here, the "angle of view" refers to the range in which a subject can be photographed through the lens of the camera. Hereinafter, the above imaging method will be briefly described. [0003] In the panoramic imaging method, images captured by multiple cameras are stitched together to generate a wide-area image. Pano...
