摘要： The resolution, frame rate, or both can be improved when imaging moving subjects in an imaging apparatus using a CMOS image sensor. 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： The decoding apparatus enabling high-speed arithmetic decoding in decoding data coded using CABAC is an arithmetic decoding apparatus which receives, as input, coded data obtained by converting multivalue information of syntax into binary data then performing Context-based Adaptive Binary Arithmetic Coding on the binary data, and which decodes the coded data into the original multivalue information. During the reconstruction of the current binary data, the arithmetic decoding apparatus, parallelly calculates, in the same cycle, “next-next identifier code” candidates and “context index” candidates corresponding to the “next-next identifier code” candidates, and, in the next cycle, parallelly calculates, in the same cycle, a “next identifier code”, context index candidates corresponding to the next identifier code, and “probability variable” candidates corresponding to the “context index” candidates, and, when the current binary data reconstruction result is known, selects the respective calculation results according to the reconstruction result.

摘要： A first table stores operand data for translation of operand virtual address into a physical address. A second table stores instruction data for translation of instruction virtual address into a physical address. The first and the second tables are formed in one memory. If operand access and instruction access are generated simultaneously, the operand access is executed with priority and the instruction virtual address is held in a wait register after that the instruction access is executed after finishing the operand access based on a wait instruction virtual address.

摘要： A higher TLB that stores TLB data required for translating a virtual address into a physical address. A higher address translator performs address translation based on the TLB data according to an access. If address translation is not possible, the higher address translator requests a lower address translator to carry out the address translation. The lower address translator performs address translation based on a lower TLB. A shift register outputs a write prohibit signal to prohibit writing of the TLB data to the higher TLB, when write data that is the same as the write data has already been written in the higher TLB.
