Image signal reproducing apparatus.

摘要

The present invention provides an image signal reproducing apparatus, in which a writing operation of memory means temporarily storing the image signal is controlled such that control means prohibits said memory means from writing the same portion of the image signal that said memory means has stored, to provide the image signal reproducing apparatus which is adequate to reproduce image data compressed by the inter-frame encoding, an image signal reproducing apparatus, in which a reading operation of memory means temporarily storing the image signal is controlled such that control means changes a unit portion of an image signal repeatedly read out from said memory means according to a motion of the image signal, to maintain the vertical resolving power for still images and to prevent the motion images to become unnatural, and an image signal reproducing apparatus, in which a writing operation of memory means temporarily storing the image signal is controlled such that control means changes a condition to allow the image signal to be written in said memory means, to reproduce the image signal having as high quality as possible.
