    摘要: An image signal encoding apparatus for encoding an image signal in which image of one picture plane consisting of a plurality of pixel data are divided into a plurality of blocks each consisting of a predetermined number of pixel data. For each of the blocks, a pair of reference value data regarding the maximum and minimum values of the levels of the pixel data constructing the block are formed. On the basis of the formed reference value data, encoded date is formed by encoding each of the pixel data of the block. Decoded data is formed by decoding the encoded data formed on the basis of the reference value data. By comparing each of the pixel data of the block with the decoded data, errors are detected. The reference value data are corrected in accordance with the result of the detection. Thus, the encoding errors are reduced and it is possible to perform the encoding with less deterioration in picture quality of the image signal.

    摘要: An image information transmission apparatus of this invention encodes and transmits image information. An image information signal of one frame consisting of a plurality of pixel data is divided into a plurality of blocks each consisting of a predetermined number of pixel data. At least two reference value data associated with a dynamic range of levels of the pixel data constituting each of the divided blocks, and distribution state data associated with a distribution state thereof are formed. Each pixel data constituting the block is encoded on the basis of the formed reference value data and the formed distribution state data to obtain encoded data. A transmission data series is formed and transmitted using the formed reference value data, the formed distribution state data, and the encoded data as transmission units. Therefore, the image information signal can be highly effectively transmitted with minimum image quality degradation caused by encoding.

    摘要: An image recording playback apparatus which, when recording moving image data, performs image capture at high-speed read time Dt, records all the captured images, and records a playback rate Ft (Vt), the read time Dt and image valid time St, with the image data, on a recording medium. Then upon playback of moving image data, the image recording playback apparatus plays back the recorded image data within the image valid time St in accordance with the playback rate. The image recording playback apparatus having this configuration can perform playback intended by a user. Further, when sharpness is to be changed, a playback image with different sharpness can be obtained by changing the image valid time St upon playback.
