摘要： An image signal processing apparatus performs gradation control on respective pixels. Specifically, the image signal processing apparatus includes an image signal processing unit which controls light emission and non-light emission of respective subfields so as to provide a field having a level of brightness. Here, the field is a unit display period of the pixels and divided into the subfields which have different light emission periods and are arranged in a predetermined sequence. In the predetermined sequence, the subfields are arranged in a manner such that a subfield having the shortest light emission period among the subfields is in the first place, one of a subfield having the longest light emission period and a subfield having the second longest light emission period among the subfields is in the second place, and the other one is in the third place.

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： A transcoder reduces the processing amount when a coded stream to which at least intra prediction is applied is transcoded into a coded stream to which intra prediction and inter prediction are applied. The transcoder converts a first coded stream to at least part of which intra prediction is applied, into a second coded stream to which intra prediction and inter prediction are applied. The transcoder includes a decoding unit that decodes the first coded stream to generate decoded image data; a prediction mode obtaining unit that obtains a prediction mode of intra prediction applied in decoding; and a coding unit that codes the decoded image data by applying the intra prediction or inter prediction to generate the second coded stream. A control unit controls causes the coding unit to use the prediction mode obtained by the prediction mode obtaining unit when the coding unit applies intra prediction.
