ABSTRACT:
An image communication apparatus such as a facsimile apparatus has: a receiving device for receiving coded data, a decoder for decoding the coded data received by the receiving device and for conducting an operation for detecting a transmission error in each of plural data lines based on the decoded data; a controller for controlling the operation of the decoder and for generating data to be recorded by conducting decoding of the coded data while removing the coded data of the lines in which a transmission error has been detected; and a recording device for recording an image on a recording sheet in accordance with the data decoded by the controller. The decoding and transmission error detection operation performed by the decoder are conducted in parallel with the decoding operation performed by the controller. The control means operates to cause the decoder to execute its own decoding operation preferentially to the decoding operation for generating the data to be recorded.
