ABSTRACT:
Successively transmitted images are stored in frame memories the contents of which are displayed. The user can freeze a desired image in order to view it for a prolonged period of time. When the image thus frozen is released from the freeze mode, the content of the frame memory storing it continues to be displayed until anew image is stored in this frame memory. When a new image has been written in the frame memory and a stage is reached in which the image is to be displayed, display-setting information pertaining to this image is read out and the image is displayed in accordance with this information. In a case where the display-setting information indicates that the image is to be displayed in combination with a designated image transmitted earlier and it is determined that the storage destination of the designated image had previously been placed in the freeze mode, this means that an unrelated image is presently being stored at this storage location. Accordingly, the image at this location is not displayed in combination with the first-mentioned image, and therefore only the first-mentioned image is displayed.
