Patent ID: 7656440

Claim:
A processing device mountable and integratable in an image sensing apparatus comprising: a logic circuit changeable to a plurality of configurations which implement functions corresponding to a plurality of processes performed by the image sensing apparatus; a memory that stores configuration information indicative of possible configurations of said logic circuit; a storage device that stores image data acquired by the image sensing apparatus; and a controller that changes a configuration of said logic circuit on the basis of the configuration information stored in said memory so that said logic circuit performs the plurality of processes in place of the image sensing apparatus, wherein said controller changes the configuration of said logic circuit to a first configuration suitable for a first process so that said logic circuit performs the first process on the image data in place of the image sensing apparatus, and, after an end of the first process by said logic circuit of the first configuration, automatically changes the configuration of said logic circuit to a second configuration suitable for a second process so that said logic circuit performs the second process on the image data on which the first process is performed in place of the image sensing apparatus.
