    Abstract: PROBLEM TO BE SOLVED: To provide a device for detecting a prescribed space pattern with high precision, regardless of variance in the sensitivity or characteristics of respective light detectors, or a long-term fluctuation in signal strength. SOLUTION: This detecting device is provided with a plurality of light detectors 11, 11,... disposed on a light-intercepting surface 102, a means for initiating a movement between the light irradiated onto the light-intercepting surface 102 and the light-intercepting surface 102, a change strength detector 22 for outputting a signal corresponding to a time change in the output signal of the light detector, and position detecting means 32, 42, 51, 61 for detecting the position of a space pattern P2 based on the output signals of the change strength detector 22, 22,... corresponding to a combination of the light detectors 11, 11,... placed at a disposing relation correlated to an assumed position where the presence of the edge part of the space pattern P2 to be detected is assumed.

    Abstract: PROBLEM TO BE SOLVED: To provide an image processor which suppresses erroneous detection of a rectangle object when detecting a target object from images. SOLUTION: The image processor 1 which detects a target object from images is equipped with; an evaluation means 11b which evaluates a degree of similarity of patterns between lines of images; and a discrimination means 11c which discriminates an object based on a degree of similarity evaluated by the evaluation means 11b. Further, the evaluation means 11b evaluates a degree of similarity of patterns between lines using the amount of characteristics of phase invariance of each line of the image.

    Abstract: PROBLEM TO BE SOLVED: To provide an image transforming device capable of compressing a dynamic range without painting out a dark part black, without making noise of the dark part conspicuous and without graying a white large object (or the area). SOLUTION: By a luminance Y1 of respective pixels of a source image, the luminance Y2 of the pixel of a low frequency image and functions C1 and C2 of the luminance Y2 , the luminance Y3 of the pixel of a transformed image is obtained by Y3 =C1 Y1 +C2 Y2 . Since C1 +C2 is fixed at Y2
