    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: In order to thin an input signal a second multiplexer is switched to output an output of a first adder and a third multiplexer is switched to output an output of a second adder, and a first multiplexer is alternatively switched at every line. A delay circuit memorizes the sum of the two preceding input signals, and the second adder outputs at every other line the sum of image data of a present line and the two preceding lines. To interpolate an input signal, the second multiplexer is switched to output the output of the delay circuit, the first multiplexer is alternatively switched to output either the input signal or the output of the second multiplexer, and the second multiplexer is alternatively switched to output either the output of the first adder or the output of the delay circuit. Thus, the delay circuit outputs at every other line the sum of the two preceding input signals. Because only one delay circuit is needed the size of the perpendicular thinning/interpolation circuit for an image signal is reduced.

    摘要: In a video signal digital magnetic recording and/or reproducing apparatus, an input image data array is rearranged into a different data array appropriate for data compression and then subjected to a data compression by variable length coding. The resulting data are rearranged after the data compression and then recorded sequentially onto a video track of a magnetic tape in the same order as that in the frame. In a high-speed playback mode, only the lower frequency component data is decoded every sync block, so that the data reproduced from one video track adjoin each other in the playback picture on the screen.

    摘要: Provided is a motion estimation device in which an amount of pixel data transferred from an external frame memory to an internal reference local memory is reduced. By the motion estimation device, it is possible to reduce a memory capacity and a size or processing of a circuit controlling the pixel transfer. In a reference memory control unit and an internal reference memory, a height of a area to be updated is set to L pixels, where L is power of 2, a logical address segments, whose size is suitable for address calculation, are allocated to picture space, and FIFO management is performs. In another application, an assistance memory is added, and another element other than the assistance memory performs the FIFO management for rectangular areas in an image of a conventional width. As a result, the address calculation is simplified, which makes it possible to reduce an embedded circuit for the reference memory control unit and the internal reference memory.

    摘要: When a method or apparatus of assuring simultaneous exposure, such as a mechanical shutter, is not provided with a MOS imaging sensor, moving subjects are distorted with a MOS image sensor when capturing a still image of a fast-moving subject because imaging and reading are not simultaneous across the MOS sensor. Changing the MOS sensor exposure sequence and reading sequence, and interpolating the read data, change and correct the read sequence line by line when imaging a high resolution moving image, and thus improve distortion in moving subjects.
