ABSTRACT:
An image communication apparatus is operable in a reception mode for received coded image data and detecting a communication error by checking specific information in the received image data. The coded data is received in a reception operation and stored in a memory in a storing operation, and a control circuit controls both operations. Specifically, the control circuit effects the storing operation in response to a manual instruction during the reception mode, and checks the specific information without decoding the received image data. The control circuit effects both the reception and storing operations in parallel during the reception mode.
