摘要： A device for coding picture data by compression, and a method thereof. By preprocessing, the device calculates a picture activity of one frame of picture data. A quantizing table circuit selects a particular quantizing step matching the picture activity and sets it in a quantizing circuit 32. On a first path, one frame of picture data is fed to a discrete cosine transform (DCT) circuit to be thereby subjected to orthogonal transform. The quantizing circuit sequentially quantizes DC components, low frequency components and high frequency components of the resulting output of the DCT circuit in ascending order of frequency block by block according to a quantizing step set therein. The picture data from the quantizing circuit are coded by Huffman coding while a code counter counts the coded data. The quantizing step set in the quantizing circuit is updated on the basis of the amount of coded data and a target amount of codes. On a second path, the same one frame of picture data is again fed to the DCT circuit to undergo orthogonal transform and compression, as on the first path. The coded picture data are sent to a memory card or similar picture data storing means. A bit distributing circuit produces a bit distribution value block by block. When the output count of the code counter associated with one block reaches the bit distribution value, the DCT circuit, quantizing circuit and Huffman coding circuit are disenabled while an EOB (End Of Block) code is added to the end of the block of coded picture data.

摘要： A digital electronic still-video camera is capable of performing rapid-sequence photography at high speeds. When a rapid-sequence photographic mode has been set, each of a plurality of frames of image data obtained by such photography is compressed. Image data which forms a single multiple-frame picture is constructed by a set of image data composed of the compressed plurality of frames. Thinning out is performed in order to compress the image data. The image data is successively stored, while being thinned out, at corresponding addresses of an image memory in such a manner that a multiple-frame picture is constructed in the image memory. After photography in the rapid-sequence mode ends, the image data in the image memory is subjected to data compression and then recorded on a memory card.

摘要： A device for coding color picture data by compression maintains compressed data in a predetermined length and prevents the amount of DC signal component data to be allocated from becoming short. A luminance signal and chrominance signals Cr and Cb are compressed independently of each other and recorded as discrete DC components and AC components. When the amount of data of DC components of the chrominance signal Cr or Cb is greater than the total amount of data assigned to the signal Cr or Cb, the amount of data assigned to the signal Cr or Cb is increased to equal the amount of data of DC components of the signal Cr or Cb while the shortage is subtracted from the allocation of AC component data of the luminance signal Y. This insures the allocation of a sufficient amount of data to the coded data of DC components at all times.

摘要： A device for coding a picture signal by compression produces, when detected that the amplitude of data which has undergone two-dimensional orthogonal transform and then normalized has overflown, data specifying the normalized data in addition to coded data of the normalized data. A decoding device, therefore, is capable of accurately decoding original picture data despite the overflow. When a block of picture data lies in a predetermined range which occurs with relatively low probability, the picture data is transformed into coded data which includes a predetermined code. When the block of picture data does not lie in such a range, the picture data is converted into Huffman-coded data. This reduces the required capacity of a look-up table for coding.

摘要： A picture recording apparatus includes a first storage having storing units, or clusters, each of which has a predetermined capacity for accommodating video data, and thereby writing video data in the first storage on a cluster basis. An inputting section receives video data to be stored in the first storage. A second storage stores in a predetermined order address data each designating, from among the clusters of the first storage, a particular unoccupied cluster. A controller searches, before writing video data in the first storage, for unoccupied clusters and writes in the second storage first address data which designate clusters necessary for accommodating the video data. A data amount determining section determines the amount of video data outputted by the inputting section and outputs, when the amount of video data matches a single cluster, a first signal for commanding the writing of the video data to the next cluster and a second signal for inhibiting the outputting operation of the inputting section. An address generating section is responsive to the first signal for reading address data representative of the next storing unit out of the second storage, generates a real address on the basis of the address data, and feeds the real address to the first storage. A selecting section selects either one of the output signals of the address generating section and inputting section and selectively feeds either one of the selected output signals and the address data outputted by the controller to the first storage.
