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： An image recording/reproducing device of this invention includes the following units. An image signal processing unit generates second captured image signals according to a second method. A first compression unit generates first compressed image data by compressing first image information that is image information included in the second captured image signals and that is equivalent to the first captured image. A second compression unit generates second compressed image data by compressing second image information that is image information included in the second captured image signals except at least a part of the image information included in the first image information. A recording unit creates first and second folders, records the first compressed is image data and first control information for reproducing the first compressed image data in association with the first folder, and records the second compressed image data in association with the second folder.
