摘要： A moving-picture conversion apparatus includes a block generator configured to generate blocks by dividing each frame forming moving picture data into the blocks, an amount-of-movement detector configured to detect an amount of movement of a subject corresponding to each block generated by the block generator, a block processor configured to receive the blocks generated by the block generator and information concerning the amount of movement detected by the amount-of-movement detector to perform decimation processing on the blocks, and a packing processor configured to receive the blocks decimated by the block processor to generate a packed block including pixel data forming the decimated blocks. The packing processor generates a packed block by correcting positions of pixels forming the packed block substantially to relative positions of the corresponding pixels forming an original image.

摘要： A down-sampling operation is performed on moving image data to reduce a sample count of the data to 1/M times the original sample count. In the down-sampling operation, a band-limitation operation is performed on the moving image data using a low-pass filter. The low-pass filter has a stop band frequency that prevents a harmonic component having a K-th order or higher, of harmonic components generated in the down-sampling operation, from overlapping an original signal component. The down-sampling operation is then performed on the band-limited moving image data, thereby compressing the moving image data. Aliasing distortion caused by a harmonic component of a high order is controlled. The resulting compressed image is free from a substantial loss of a high-frequency component of the original signal.

摘要： In an apparatus that converts (compresses) motion image data, the amount of motion of a subject in a block of motion image data is detected, and spatial decimation is performed in a mode in which sampling point positions are fixed or in a mode in which sampling point positions are shifted, depending on the detected amount of motion. When predicted image quality corresponding to the moving speed of a subject detected by analyzing blocks is lower than a predetermined threshold level, spatial decimation is performed in the mode in sampling point positions are shifted such that the moving speed of the subject is virtually changed to a value at which a super resolution effect occurs, thereby achieving data conversion without causing significant degradation in image quality.

摘要： When an output unit is capable of operation at a frame rate F and a resolution of x×y pixels, an imaging unit or an image input unit converts an image into an imaged frame in an internal data format having the frame rate F and a resolution of ix×jy pixels. An image converter converts the resolution of the imaged frame supplied from the imaging unit or the image input unit into a resolution that can be represented by the output unit, generating an output frame having x×y pixels. At this time, the image converter carries out predetermined resolution conversion based on a moving velocity of the image by blocks each having a predetermined size. Thus, such visual effect that an observer of the image of the output frame perceives the image at a resolution exceeding the actual resolution of the output frame is achieved.
