  • Publication number: 20060098893
    Abstract: The present invention takes into consideration the real world where data was acquired, and enables obtaining of processing results which are more accurate and more precise as to phenomena in the real world. A data continuity detecting unit 101 detects the continuity of data of second signals, having second dimensions that are fewer than first dimensions had by first signals which are real world signals and are projected whereby a part of the continuity of the real world signals is lost, wherein the continuity to be detected corresponds to the continuity of the real world signals that has been lost. An actual world estimating unit 102 estimates a real world image by estimating the continuity of the real world image that has been lost, based on the continuity of the data detected by the data continuity detecting unit 101.

  • Patent number: 7024050
    Abstract: An object of the present invention is to make it possible to adjust the amount of motion blur contained in a blurred image. A unit-of-processing determining portion 901 determines the unit of processing which is formed of pixel data located on a straight line. An equation generator 903 generates simultaneous equations consisting of a plurality of relational expressions based on the unit of processing. A calculator 904 generates foreground object components in which the amount of motion blur is adjusted by solving the simultaneous equations. The present invention can be applied to an image processing apparatus in which a difference between a signal detected by a sensor and the real world is taken into consideration.

  • Publication number: 20050259870
    Abstract: An object of the present invention is to enable the detection of a mixture ratio indicating the mixture state of a plurality of objects, such as a background image and a moving object image. A normal-equation adder 541 extracts mixed pixel data according to a motion, and also extracts background pixel data corresponding to the mixed pixel data so as to generate relational expressions for a designated pixel. A normal-equation calculator 542 detects the mixture ratio indicating the mixture state of the objects based on the relational expressions. The normal-equation adder 541 generates the plurality of relational expressions based on a first approximation in which foreground object components change substantially linearly, and a second approximation in which the mixture ratio changes substantially linearly. The present invention is applicable to a signal processing apparatus for processing images.

  • Publication number: 20050200723
    Abstract: An image signal generated by a CCD image sensor is processed by the block-generating section 28 provided in an image-signal processing section 25. A class tap and a prediction tap are thereby extracted. The class tap is output to an ADRC process section 29, and the prediction tap is output to an adaptation process section 31. The ADRC process section 29 performs an ADRC process on the input image signal, generating characteristic data. A classification process section 30 generates a class code corresponding to the characteristic data thus generated and supplies the same to an adaptation process section 31. The adaptation process section 31 reads, from a coefficient memory 32, the set of prediction coefficients which corresponds to the class code. The set of prediction coefficients and the prediction tap are applied, thereby generating all color signals, i.e., R, G and B signals, at the positions of the pixels which are to be processed.

A signal processing unit 107 detects pixel components on the basis of a model for separating first pixel values obtained in a processing unit time by the CCD 102 into a plurality of the pixel components corresponding to detection positions of the object being detected, and generates second pixel values corresponding to the detection positions of the object being detected on the basis of the detected pixel components. The present invention is applicable to scanners.

  • Publication number: 20040201753
    Abstract: A signal processor 12 acquires a second signal obtained by detecting a first signal, as a signal of the real world, having a first dimension. The second signal is of a second dimension lower than the first dimension and has distortion relative to the first signal. The signal processor 12 performs signal processing which is based on the second signal to generate a third signal alleviated in distortion as compared to the second signal.

  • Publication number: 20040081335
    Abstract: An object of the present invention is to make it possible to detect an area in which mixture occurs. An object extracting unit 251 extracts a foreground object from an input image to generate an area-specified object which is formed of a foreground image object and a value indicating that the object belongs to a background area. A motion compensator 252 compensates for the motion of the area-specified object based on the supplied motion vector and positional information thereof. A subtracting unit 254 subtracts the pixel value of a pixel belonging to a foreground area of the area-specified object in frame #n−1 supplied from frame memory 253 from the pixel value of a pixel belonging to a foreground area of the area-specified object in frame #n supplied from the object extracting unit 251, in which the pixels are at the corresponding position, so as to obtain a frame difference between the pixels belonging to the foreground area.

  • Publication number: 20040075749
    Abstract: The present invention makes it possible to process at high speed the foreground component image and the background component image of picked up images on a network platform. A client computer 27 outputs information specifying image data desired to separate to a separation server 11. The separation server 11 obtains the specified image data from a storage server 18 and outputs it to a motion detecting server 12 to perform motion detection processing. Thereafter, the image data, motion vector and positional information are output to an area specifying server 13. The area specifying server 13 generates area information of the image data and outputs the area information to a mixture ratio calculating server 14 in addition to the image data, the motion vector and the positional information.
