Abstract

Image data photographed by a video camera 20 are compressed by a compression and decompression circuit 5, the compressed image data are recorded in an incorporated type semiconductor memory 6 or disk-type memory 13 fixed in the video camera 20 and the recorded image data are transferred to an external recording device 23. Further, the external recording device 23 records the transferred image data in a data storage while they are being compressed. The video camera 20 receives, decompresses and converts into a television signal the compressed image data read by the external recording device 23 in reproducing them. A video camera system capable of recording and reproducing long hours of image data by using a video camera having an ultra small size comparable to that of an 8 mm video cassette can be realized by using such a construction.
