To provide an image processor that can mutually be utilized by an image input device and an environment using commands used for an IIP protocol or the like and to provide an image processing method and a memory read by a computer.

An image input section 111 inputs a picture. An image resolution conversion circuit 112 converts resolution of the received picture. Furthermore, an image form conversion circuit 113 converts a form of the received picture. Then an IIP protocol interpreting section 114 interprets a request including a command requesting a partial picture of a transfer object and its resolution at least. Then a communication control section 118 transfers the partial picture to an external device on the basis of the decoded command.
