    摘要： The present invention enables processing results which are more accurate and which have higher precision as to events of the real world to be obtained. A non-continuity component extracting unit 201 detects discontinuity portions of pixel values of multiple pixels in an input image. A peak detecting unit 202 detects a peak of change of pixel values from a discontinuity portion. A monotonous increase/decrease detecting unit 203 detects monotonous increase/decrease regions wherein pixel values increase or decrease monotonously from the peak. A continuousness detecting unit 204 detects a monotonous increase/decrease region where another monotonous increase/decrease region of the monotonous increase/decrease regions exists at an adjacent position on the screen, as a continuity region having data continuity. A data continuity direction detecting unit 301 detects the direction of continuousness of the continuity region. An actual world estimating unit estimates real world lights signals by estimating the continuity of the real world light signals, based on the continuity region and the direction of the continuousness of the continuity region. The present invention can be applied to an image processing device for generating images with high resolution.

    摘要： With the present invention, data continuity is used at the time of converting an input image into high-quality image data with higher quality than the input image data, to obtain processing results which are more accurate and have higher precision. A class tap extracting unit (902) and prediction tap extracting unit (906) extract a class tap and prediction tap based on data continuity of multiple perimeter pixels corresponding to a pixel of interest in the input image, detected by a data continuity detecting unit (901). An image synthesizing unit (909) selectively outputs a prediction value of a first pixel of interest and a prediction value of a second pixel of interest, based on the relation between a prediction value, predicted by a pixel value predicting unit (907), of the first pixel of interest, and a second prediction value of the second pixel of interest temporally or spatially adjacent to the first pixel of interest, and the pixel value of a corresponding pixel in the input image situated at a position encompassing at least the first pixel of interest and the second pixel of interest in the temporal direction or spatial direction, which is detected by an integration property determining unit (908).

    摘要： The present invention provides a mechanism for preventing quality degradation of decoded data during the decoding of encoded data. In one embodiment, error propagation is detected and corresponding data is flagged. An error recovery process is then applied to the flagged data. In an alternate embodiment, scores for hypotheses are calculated for lost/damaged data. A score distribution is used for detection of the false hypotheses. The data are flagged if their score distribution is within a range defined by a threshold and an error recovery process is applied to recover those data having associated error flags set.

    摘要： 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.
