[0005]However, signal processing for estimating a first signal from a second signal has not considered the fact that by being a real-world signal with a first dimension A second signal of a second dimension of a lower dimension than the first dimension produced by the first signal in which part of the 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

[1981] exist Figure 221 , the X direction and the Y direction represent the X direction and the Y direction of the sensor 2 ( Figure 220 ).

[1982] 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.

[1983] Note that region 2301 is part of the continuity optical signal (continuity region). On the other hand, in Figure 221 In , 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.

[1984] In addition, the white portion in the area 2301 represents the optical signal corresponding to the thin line. Therefore, the re...

Abstract

An image processing device and method, a recording medium, and a program. A simplified angle detection section (901) detects an angle of the steady state in the simple way by using correlation from the input image. A judgment section (902) connects a switch (903) to a terminal (903a) when the angle obtained in the simple way is near to the horizontal direction or the vertical direction and outputsthe angle information detected in the simple way to a regression type angle detection section (904). The regression type angle detection section (904) detects and outputs the angle of the steady state in the regression way statistically. On the other hand, when the angle of the steady state obtained in the simple way is near 45 degrees, the judgment section (902) connects the switch (903) to a terminal (903b). Here, a slope type angle detection section (905) detects and outputs the direction of the steady state from the input image in the slope way. As a result, it is possible to detect the angle of the steady state more accurately.

Description

[0001] This application is a divisional application of the patent application with the application number 200480005243.9, the application date is February 13, 2004, and the invention title is "image processing device and method, recording medium and program". technical field [0002] The present invention relates to an image processing device and method, a recording medium, and a program, and particularly relates to an image processing device and method, a recording medium, and a program in consideration of the real world from which data is acquired. Background technique [0003] 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. [0004] In addition, Japanese Unexamined Patent Application Publication No. 2001-250119 disclo...
