Abstract:
1. A picture phone apparatus comprising: an image picking section which picks up a picture data; a display section; a substitution picture storage section which stores a substitution picture data; an image processing section which checks whether said picked-up picture data is valid or invalid based on at least one of brightness data of said picked-up picture data and spatial frequency of said picked-up picture data, retrieves said substitution picture data from said substitution picture storage section to output as transmission picture data when it is determined that said picked-up picture data is invalid, sets said picked-up picture data as said transmission picture data when it is determined that said picked-up picture data is valid, and encodes said transmission picture data; and a communication processing section which multiplexes said encoded transmission picture data and transmission audio data into transmission data and transmits said transmission data to a counter station.
