A communication apparatus includes a main unit and a communication control unit. The communication control unit informs the main unit of an incoming call. The main unit makes a judgement on whether the incoming call should be accepted. In accordance with this judgement, the main unit instructs the communication control unit to respond to the incoming call. The communication control unit responds to the incoming call in accordance with the judgement by the main unit. In accordance with the state of a memory for storing received signals or with the called party number, the main unit makes a judgement on whether the incoming call should be rejected or ignored.

Communication apparatus

A facsimile apparatus includes a reading unit for reading an original, a discrimination unit for discriminating red images in the image representation provided by the reading unit, a conversion unit for converting, into black images, images discriminated as red images by the discrimination unit in the image representation, and for converting black images into images having a predetermined repeating pattern which look gray, and a transmission unit for performing fascimile transmission of the images converted by the conversion unit.

Facsimile apparatus capable of reading an original having a two-color

A decoding processing is executed in a multiple processing at high speed with a simple construction or control in a manner such that the image memory 11 stores an input compressed code, the multiplexer 14 selects the compressed code shift circuit 12 or 13 where the compressed code is shifted, and the decoder 15 decodes the shifted compressed-code.

Apparatus for processing multiple images in alternating fashion

This invention provides an image processing method and apparatus. Two types of edge emphasis processing operations having different degrees of edge emphasis are performed for image data of a read original. When paper quality of the original instructed by an operation unit is recycle paper, the edge emphasis processing having a smaller degree of the two types of edge emphasis processing operations is selected. The selected (multi-value) image data is binary-converted, and the binary-converted image data is output, thereby obtaining good image quality with respect to the read original regardless of the paper quality of the read original.
