Abstract: Image data photographed by a video camera 20 is compressed by a compression and decompression circuit 5, the compressed image data is recorded in an incorporated type semiconductor memory 6 or disk-type memory 13 fixed in the video camera 20 and the recorded image data is transferred to an external recording device 23. Further, the external recording device 23 records the transferred image data in a data storage while it is 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 a reproducing operation. 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.

Abstract: An image pickup apparatus includes: an image pickup portion for picking up a subject image to generate image data and reading out the generated one frame image data that is divided into plural fields; a storage portion for temporarily storing the image data obtained by performing predetermined processing on the image data that has been read out; and an image processing portion for generating record image data and auxiliary image data for a use other than recording, based on the image data that has been stored in the storage portion. The record image data is generated using image data of all of the fields of the one frame of the image data, and the auxiliary image data is generated using image data of a subset of the fields of the one frame of the image data. The variation of the amount of compressed data is reduced, the processing time is reduced, and the capacity requirement of the buffer memory is reduced.
