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.

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.

An image processing apparatus includes a determining unit, a converter, and a display unit. The determining unit receives image data for three-dimensional display as input, and determines the three-dimensional display format corresponding to the input data. The converter converts the input data in accordance with the determination results from the determining unit. The display unit displays the converted results from the converter.
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.

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.
