摘要:
The present invention relates to a data structure, a reproducing apparatus, a reproducing method, and a program which are applicable to various types of display and which facilitates signal processing performed in the displays. In a 3D video format according to the present invention, a base signal BS of a side-by-side image SbSP and an optional signal OS of a sub-image SuP obtained by collectively arranging three images described below regarding an L image LP of the side-by-side image SbSP are used. That is, the sub-image SuP includes a Depth image of the L image, an image hidden behind an object included in the L image, and a Depth image of the mage hidden behind the object. The present invention is applicable to 3D displays.

In an image pickup apparatus, a level compensator compensates the level of an image xL (i, j) sensed by an image sensor by exposure for a long time on the basis of the exposure of the image to produce a compensated image xL′ (i, j), while another level compensator compensates the level of an image xS (i, j) sensed by the image sensor by exposure for a short time on the basis of the exposure of the image to produce a compensated image xS′ (i, j). The image pickup apparatus also includes an image synthesizer to synthesize these compensates images xL′ (i, j) and xS′ (i, j) to produce a single synthetic image x (i, j). A dynamic range compressor also included in the image pickup apparatus compresses the synthetic image x (i, j) to produce a compressed image y (i, j) for delivery to outside.

An image capturing apparatus and a method therefor are proposed for the production of a natural composite image corresponding to an object to be imaged. A misregistration amount (d) of each image (xS1) except for a reference image (xL1) is detected with respect to the reference image, misregistration of each image except for the reference image with respect to the reference image is corrected on the basis of the misregistration amount, and then the reference image and each misregistration corrected image (xS4) except for the reference image are composed, thereby making it possible to avoid a degraded image quality which would otherwise be produced when a plurality of images are composed without correction, and consequently produce a natural composite image corresponding to an object to be imaged.

A picture is divided into either one of three types of macroblocks and then encoded in such a manner that block distortion, mosquito noise and ringing are reduced while picture coding efficiency is improved.
摘要:
An image encoding method and apparatus, an image decoding method and apparatus, and an image recording medium are provided for suppress the diffusion of the quantizing noise components of the wavelet coefficient or the subband coefficient caused by the band division with the wavelet filter or the subband filter and the quantization, thereby narrowing the area where the ringing takes place. The image encoding method is arranged to detect a motion vector from an input image signal, derive a difference between the input image signal and a predicted image signal, detect a meaningless area from the difference image signal and output information about the meaningless area; subband-convert the difference image signal for outputting a subband coefficient, quantize the subband coefficient, de-quantize the quantized subband coefficient, invert the decoded subband coefficient for outputting a decoded difference image signal, smooth the decoded difference image signal based on the information about the meaningless area, add the predicted image signal to the smoothed difference image signal for producing a decoded image signal, motion-compensate the decoded image signal with the motion vector for outputting the predicted image signal, and output the quantized subband coefficient, the information about the meaningless area, and the motion vector as encoded data. The decoding method takes the substantially reverse operation as the encoding method.
