Apparatus for and method of recording high resolution image, and apparatus for and method of reproducing the same

An apparatus for recording high resolution image data, which is successively inputted from the external at a predetermined timing, to a recording medium of random access type, comprising:

• a memory for storing one entire portion of a plurality of contiguous portions of the high resolution image data corresponding to one picture plane at a timing based on a record control signal, which is cyclically inputted, and not storing any part of any other portion of said plurality of contiguous portions of the high resolution image data following said one portion and corresponding to another picture plane, during a predetermined time interval based on a cycle of the record control signal;
• a converter coupled to said memory, for dividing and converting said one portion of the high resolution image data stored in said memory into a plurality of standard image data corresponding to a standard television system one after another;
• a recording device coupled to said converter, for recording the plurality of standard image data to the recording medium by a unit of field or frame;
• and
• a control device for generating the record control signal by the cycle which prescribes said predetermined time interval to be enough for said memory, said converter and said recording device to respectively perform storing, converting and recording operations with respect to said one portion of the high resolution image data.

A method of recording high resolution image data, which is successively inputted from the external at a predetermined timing, to a recording medium of random access type, comprising the steps of:

• successively storing into a memory one high resolution image data by a unit of picture plane at a timing based on a record control signal, which is cyclically inputted, such that said one high resolution image data is held by said memory for one cycle of the record control signal;
• dividing said one high resolution image data stored in said memory into N portions corresponding to N contiguous divided areas of one picture plane, and entirely converting only one of the N portions to standard image data corresponding to a standard television system and not converting any part of the remaining portions, such that said converted one of the N portions is sequentially shifted each time when said one high resolution image data is held, and that N standard image data, which are successively converted during a time interval corresponding to N cycles of the record control signal, cover one picture plane in a time divisional manner;
• recording the standard image data to the recording medium by a unit of field or frame;
• and
• generating the record control signal by the cycle which prescribes said predetermined time interval to be enough for said memory, said converter and said recording device to respectively perform storing, converting and recording operations with respect to said one portion of the high resolution image data.
