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： A MOS image sensor and an imaging apparatus using this image sensor enable controlling sensor driving with a high degree of freedom using a simple control circuit design and minimal wiring lines. The light reception unit of the image sensor in this imaging apparatus is segmented into a plurality of areas and conventional shift registers are constructed in multiple layers, thus enabling controlling the multiple sensor areas by means of a relatively simple circuit design. The imaging apparatus can thus locally change exposure and imaging conditions in parts of a single frame. Problems due to underexposure and overexposure are thus suppressed, and images with a wide dynamic range can be captured.

摘要： A device is provided for taking high resolution still pictures while recording video without pausing video recording. Plural channels are provided for reaching pixel values from a CMOS sensor, and the output of each channel is input to a corresponding A/D conversion circuit. The channels are configured so that the pixels that are added together are read simultaneously. The data added by the pixel value adder is used as the video data for video recording. When a still picture is captured during video recording, the pixel data is stored in memory with capacity to store one frame, and is sequentially output from the image sensor as the still picture data.

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.

摘要： An image coder with a pre-record function includes a coding unit (11) which codes a motion-picture signal to generate closed GOPs or open GOPs, a buffer unit (14) in which at least one of the GOPs generated by the coding unit (11) is stored in a first-in first-out manner, a user I/F unit (12a) which receives instructions to start or stop capturing a moving picture, and a recording control unit (12b) which, before the user I/F unit (12a) receives an instruction to start capturing a moving picture, establishes a non-recording status and causes the coding unit (11) to start and continue coding the motion-picture signal so as to generate a GOP sequence including a closed GOP, and when the user I/F unit (12a) receives the instruction, switches from the non-recording status to a non-recording status and causes the coding unit (11) to generate a GOP sequence including only open GOPs.
