[0004] However, the signal processing for estimating the first signal from the second signal has not taken into account the fact that the lower dimensional A second signal of a second dimension in which partial continuity of the real-world signal is lost has a data continuity corresponding to the stability of the real-world signal that has been lost

specific example

[0983] In FIG. 122, the X direction and the Y direction represent the X direction and the Y direction of the sensor 2 (FIG. 121).

[0984] A portion 2301 of the optical signal of the real world 1 (hereinafter, the portion refers to an area) represents an example of an area having predetermined continuity.

[0985] Note that region 2301 is part of the continuity optical signal (continuity region). On the other hand, in FIG. 122 , the area 2301 is shown as being actually divided into 20 small areas (square areas). This is for illustration, the size of the area 2301 is equal to the size of four detection elements (pixels) of the sensor 2 arranged in the x direction, and five detection elements (pixels) of the sensor 2 in the y direction. That is, every 20 small areas (virtual areas) in the area 2301 is equal to one pixel.

[0986] In addition, the white portion in the area 2301 represents the optical signal corresponding to the thin line. Therefore, the region 2301 has continu...

Abstract

It is possible to obtain a processing result of an event of the real world with a high accuracy. A non-constant component extraction section (201) detects a discontinuous portion of the pixel value of a plurality of pixels of the input image. A vertex detection section (202) detects a vertex of the pixel value change from the discontinuous portion. A monotonous increase / decrease detection section (203) detects a monotonous increase / decrease region where the pixel value monotonously increases or decreases from the vertex. A continuity detection section (204) detects a monotonous increase / decrease region containing another monotonous increase / decrease region at an adjacent position on the screen in the monotonous increase / decrease region, as a constant region having data constancy. A data constancy direction detection section (301) detects the direction of continuity of the constant region. According to the constant region and the direction of the continuity of the constant region, the real world estimation section estimates constancy of the optical signal of the real world, thereby estimating the optical signal of the real world. The present invention can be applied to an image processing device for generating an image of high resolution.

Description

technical field [0001] The present invention relates to an image processing device, method and program, and more particularly to an image processing device, method and program considering the real world from which data is acquired. Background technique [0002] A technique of detecting phenomena in the real world (real world) using sensors and processing sampled data output from the sensors is widely used. For example, image processing techniques are widely used in which the real world is imaged with an imaging sensor and sampled data as image data is processed. [0003] In addition, Japanese Unexamined Patent Application Publication No. 2001-250119 discloses obtaining a second dimension lower than the first dimension by using a sensor to detect a first signal which is a real world signal having the first dimension obtaining a second signal comprising distortion relative to the first signal; and performing signal processing based on the second signal to produce a third sign...
