Abstract
An image processing apparatus, for an image recording and reproducing system, comprises a means for writing a given field image signal in a field memory, and a means for reading out the field image signal written in the field memory. The reading means reads out individual lines in sequence in a first field of the field image signal and also reads out a plurality of lines in a second field of the field image signal concurrently.
Claims6
An apparatus for producing an image, comprising:
- a producing unit, arranged for producing an image signal which sequentially includes a plurality of fields, the image signal being composed from a luminance component signal and a chrominance component signal;
- a memory, arranged for storing the produced image signal produced by said producing unit, on an each signal component basis;
- a detector, arranged for detecting whether or not a field of the produced image signal coincides with a field of the image signal read out from said memory;
- and
- a controller, arranged for controlling a timing for storing the produced image signal into said memory, so as to attain coincidence of the field of the produced image signal and the field of the image signal read out from said memory in a case that said detector detects that those two fields do not coincide with each other.

A method of producing an image, comprising:
- a producing step of producing an image signal which sequentially includes a plurality of fields, the image signal being composed from a luminance component signal and a chrominance component signal;
- a storing step of storing the produced image signal produced in said producing step, in a memory on an each signal component basis;
- a detection step of detecting whether or not a field of the produced image signal coincides with a field of the image signal read out from said memory;
- and
- a control step of controlling a timing for storing the produced image signal into said memory in said storing step, so as to attain coincidence of the field of the produced image signal and the field of the image signal read out from said memory in a case that said detection step detects that those two fields do not coincide with each other.
