Freely configurable image processing apparatus

An image processing apparatus, comprising:

• a plurality of processing sections each executing a specified type of processing on a digital image signal;
• and
• a controller coupled to said plurality of processing sections and configured for setting a sequence of processing on an image signal by said plurality of processing sections, according to a signal indicative of said sequence of processing;
• wherein said controller comprises:
• a plurality of buses connecting said plurality of processing sections and carrying image signals,
• an input selector coupled to the plurality of buses and a processing section of the plurality of processing sections and configured for selectively fetching an image signal from one of the plurality of buses into said processing section,
• an output selector coupled to the plurality of buses and a processing section of the plurality of processing sections and configured for selecting one of the plurality of buses to which an image signal from said processing signal is output, and
• a selector control section coupled to said input selector and said output selector and configured for selecting one of the plurality of buses by means of switching said input selector and said output selector.
