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 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 signal compression coding device is disclosed which divides digital picture data constituting a single picture into a plurality of blocks and codes the picture data block by block by two-dimensional orthogonal transformation. An orthogonal transforming section transforms the digital picture data divided into the plurality of blocks by two-dimensional orthogonal transformation. A normalizing section normalizes the transformed data, while a coding section codes the normalized data. A block activity calculating section calculates an activity of the picture data block by block. An activity summing section sums the block-by-block activities to produce a total activity. A coded data distributing section calculates an amount of coded data to be distributed to each of the blocks on the basis of the ratio of the block-by-block activity to the total activity. A coded output control section limits the amount of coded data to be distributed to each of the blocks from the coding section in response to an output of the coded data distributing section. The block activity calculating section has a subdividing section for subdividing each of the blocks of picture data into a plurality of subblocks, a subblock activity calculating section for calculating the activity of the picture data subblock by subblock, and a difference calculating section for determining a difference between nearby ones of the subblocks with respect to the mean value of subblock-by-subblock picture data.

摘要： An image signal recording apparatus achieves an orthogonal transform and a compression coding on image data so as to record the resultant data in a recoding medium. There is disposed a selector to select a compression ratio for the compression coding of the data, namely, the compression ratio is selectable. The selected compression ratio data is recorded in the recording medium together with the image data. A playback apparatus reads from the recording medium the compression ratio data together with the image data undergone the compression coding so as to decode the image data by use of the compression ratio data. In consequence, according to these apparatuses, the compression ratio can be arbitrarily set. In addition, the image signal recording apparatus generates recording codes associated with the amounts of the image data and the audio data so as to write the codes in the recording medium. The recording codes are read from the recording medium, so that the remaining amount of the recording medium available for the recording operation is displayed.
