摘要： As an orthogonally transformed signal carries a value adjacent to zero, the output of an orthogonal transformer is coupled in series to a fixed length code encoder for converting the orthogonally transformed signal into a fixed length code signal which exhibits less bit inversion between positive and negative signals near zero. The orthogonal transformer and the fixed length code encoder constitute in combination an orthogonal transformer device.

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.

摘要： A conventional stereo image pickup device forms an appropriate stereo image by changing the stereo base in accordance with the distance to a subject, but fails to select an appropriate focal length or stereo base by simply using the subject distance without obtaining the subject size. A stereo image pickup device (1000) estimates the size of a subject in accordance with the imaging mode set in a typical two-dimensional camera, and estimates the subject distance using the estimated size of the subject and the focal length, and further calculates the stereo base that enables an optimum disparity to be achieved using the subject distance, determines the stereo base, and aligns the two imaging units (the first imaging unit (103) and the second imaging unit (104)). As a result, the stereo image pickup device forms a stereo image having an appropriate stereoscopic effect.
