Claim:
1. A data processing apparatus comprising: a central processing unit (CPU); a dynamically reconfigurable circuit of which a circuit configuration can be configured dynamically; a memory storing first configuration data for configuring a first parameter output circuit which outputs a first parameter as a fixed value, second configuration data for configuring a second parameter output circuit which outputs a second parameter as a fixed value, and third configuration data for configuring a data processing circuit which performs data processing using the first parameter or the second parameter; and a configuration controller which configures the first parameter output circuit in the dynamically reconfigurable circuit using the first configuration data stored in the memory, and configures the data processing circuit in the dynamically reconfigurable circuit using the third configuration data stored in the memory, wherein the data processing circuit configured in the dynamically reconfigurable circuit performs data processing using the first parameter outputted from the first parameter output circuit configured in the dynamically reconfigurable circuit, wherein the configuration controller, when the data processing to be performed by the data processing circuit is changed from the data processing using the first parameter to the data processing using the second parameter, reconfigures the second parameter output circuit in the dynamically reconfigurable circuit using the second configuration data stored in the memory, without reconfiguring the data processing circuit, wherein the data processing to be performed by the data processing circuit is image processing for copying, and wherein a change by the data processing circuit from image processing using the first parameter to image processing using the second parameter is performed due to a change from color copy to monochrome copy or a change from monochrome copy to color copy.
