ABSTRACT:
A still image transmitting device including a control unit, a demodulating unit for converting 25-bit data reproduced from a video tape into 24-bit data, an error correction unit that receives the 24-bit image data and corrects errors caused by the video tape, a data restoring unit for restoring original data by performing an inverse discrete cosine transform, variable length decoding, run length decoding, and de-quantization with compressed data and storing the restored data in a shuffle memory before de-shuffling. A sync signal insertion and over sampling unit is provided for converting the de-shuffled image data into a composite video broadcasting signal to output to a monitor or for converting the de-shuffled image signal into luminance and color signals. A still image transmitting unit transmits still image data according to control signals transmitted by the control unit, and an interface unit transmits control signals from the personal computer to the still image transmitting unit, and also transmits an image signal produced by the still image transmitting unit to the personal computer.
