摘要： A device is provided for taking high resolution still pictures while recording video without pausing video recording. Plural channels are provided for reaching pixel values from a CMOS sensor, and the output of each channel is input to a corresponding A/D conversion circuit. The channels are configured so that the pixels that are added together are read simultaneously. The data added by the pixel value adder is used as the video data for video recording. When a still picture is captured during video recording, the pixel data is stored in memory with capacity to store one frame, and is sequentially output from the image sensor as the still picture data.

摘要： The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output.

摘要： A video data is accompanied or multiplexed with one or more flags indicating a relation between fields or frames of video data for transmission or recording. An interlace flag determines whether the video data is interlaced or not. A still image flag determines whether the video data carries a motion image, a field still image, or a frame still image. A frame change flag determines whether or not a given frame of the still image is identical to its previous frame. At least one of the three different flags is multiplexed with its relevant video data.
