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.

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.
