摘要： There is provided code amount control in which information data are input in predetermined units and a code amount is estimated in each of a plurality of stages, including a final stage. A calculation result is obtained based on a target code amount and the estimated code amount, for each stage.

摘要： A CCD converts an optical image of an object formed on its image sensing surface into electrical charges, and sequentially outputs the electrical charges of all of the light receiving pixels in one scanning operation in non-interlaced form. The outputs from the CCD are converted to the digital image signals by an analog-digital converter. A camera signal processing unit processes the digital image signals, thereby generating two streams of signals; one is digital video signals SV1 which are standard digital video signals in interlaced form, and the other is signals SV2 which are not outputted as the digital video signals SV1 out of the digital image signals of all of the light receiving pixels. These two streams of signals, SV1 and SV2, are processed differently depending upon a mode selected by a switch.

摘要： A video signal recording and reproducing system enables recording and reproducing of a video signal with high quality. The system includes a recording system for recording the video signal on a record medium by a median filter and a reproducing system for reproducing the video signal from the record medium. The recording system separates a brightness signal and a color signal from an interlaced scanning signal. The recording system divides picture elements of each line into two phases by sorting the elements such that an element is put into one phase and the next element into the other. The recording system then carries out two-dimensional subsampling to the brightness signal and the color signal to reduce the amount of data. Then, the recording system compresses and time-division multiplexes the brightness signal and the color signal to provide a video signal to be recorded onto a record medium. The reproducing system separates the brightness signal and the color signal from a video signal read out from the record medium, and then interpolates picture elements into the two signals to obtain sequential scanning RGB signals for 525 scanning lines.
