摘要： A video signal digital recording and reproducing apparatus includes: a rearranging section for rearranging a sequence of signals on a rectangular unit by rectangular unit basis formed by sectioning a group of pixel data on a screen of a digital video signal; an encoding section for subjecting the signals in the rectangular units to bit rate reduction; a block forming section for gathering plural number of the coded rectangular units to constitute a block of signals, and a recording the block of signals section for recording on a recording medium. The rearranging section divides the screen into plural regions, takes out the rectangular units by a certain number in order from each region, and carries out rearrangement so that mutually corresponding rectangular units which are contained respectively in adjacent blocks on the recording medium are mutually adjacent on the screen. The recording section is constituted so that the blocks signals are recorded simultaneously in parallel on the recording medium by using plural channels. The rearranging section may have such a constitution that the screen is divided into plural regions and the rectangular units are taken out by a certain number in order from each region, and rearrangement is carried out to that mutually corresponding rectangular units which are contained respectively in adjacent or neighboring blocks to be simultaneously recorded in parallel by the plural channels on the recording section are mutually adjacent on the screen.

摘要： A conventional device adjusts the convergence angle of its imaging unit in a manner that the left-and-right face detection areas are at the same coordinates and thus forms a stereo image that will be placed on a display screen during display, but fails to place a subject at an intended stereoscopic position. A stereo image capturing device (1000) detects a face area from a right image, detects a disparity using the left-and-right face areas, and sets the imaging parameters (the subject distance, focal length, stereo base, and convergence angle) to adjust the detected disparity to a disparity enabling the subject to be placed at an intended placement position. This device forms a stereo image having an appropriate stereoscopic effect in which a target subject is placed at an intended stereoscopic position. The device uses only a limited target area for face detection and thus requires less calculation for face detection.

摘要： An image encoding method is for obtaining, from a pixel data string containing pixel values of a plurality of pixels in a pixel array where the pixels are arrayed, a pixel data string containing a quantized representative value into which at least one of the pixel values is encoded. Encoding is performed by allocating a specific quantized representative value when a pixel value of a pixel is a specific pixel value, and by allocating a quantized representative value other than the specific quantized representative value when the pixel value is other than the specific pixel value.

The imaging apparatus has an image sensor having a two-dimensional array of pixels. Each of the pixels includes an element operable to produce an electric charge by photoelectrically converting light from an imaged subject and a part operable to accumulate the produced charge and output an accumulated charge or a signal representing the accumulated charge. The imaging apparatus also has an area control unit operable to define a specified area of the image sensor containing a plurality of pixels and an area density control unit operable to specify a density of pixels read from the specified area defined by the area control unit.

摘要： The present invention provides a video encoding device in which a capacity of a binary data storing unit is small, a size of the video encoding device is small, a video signal can be processed in real time, and reduction in quality of images generated from the eventually obtained data can be prevented. The video encoding device according to the present invention includes: a video encoding unit which encodes a video signal; a binarization unit which binarizes an encoded value obtained from the video encoding unit; and an entropy encoding unit which subjects entropy encoding to binary data obtained from the binarization unit. Here, the video encoding unit encodes the video signal based on a characteristic of the binarization performed by the binarization unit, so that an amount of binary data obtained from the binarization unit by binarizing the encoded value that is encoded based on the characteristic is less than an amount of binary data obtained by binarizing an encoded value that is encoded without being based on the characteristic.
