Abstract: In order to achieve a processor that does not require processing time for branching processing and is ensured the flexibility of the processing content, an adder adds a start address stored in start address parts and selected by a selector and a stored content (relative address) of a program counter to output a current execution instruction address. An execution unit executes an instruction of the address of a program storing part. A comparator compares the address with an end address stored in end address storing parts and selected by a selector. When the addresses are matched, the selectors are switched, and the program counter is reset, so that branching can be performed without requiring an instruction cycle. The start address storing parts are rewritten by a supervisory processor, where appropriate.

Abstract: A camera of the type in which a rotary filter having color filter sections formed for three different colors is rotated between an image pickup and an object and the image pickup repeatedly stores one frame of a video signal therein. The camera comprising a rotation controller, a memory and an output controller. The rotation controller controls the rotation of the rotary filter in such manner that the image pickup scans by at least two frames of the video signal for a certain residence time during which each of the color filter sections is disposed between the image pickup and the object. The output controller controls the outputting of the video signal from the image pickup into the memory. The output controller inhibits the image pickup from outputting into the memory the first frame of the video signal during residence time.
