1. An image processing apparatus that performs image processing every fundamental cycle by performing a plurality of processes on data of an image picked up by a camera device, the apparatus comprising: a process setting section that constitutes the fundamental cycle, in which a series of the image processing are performed, from a plurality of unit cycles, and that selects, from the plurality of processes, the processes that are performed and sets a combination of the selected processes for each of the plurality of unit cycles constituting the fundamental cycle, in accordance with a priority of each of the plurality of processes; and a processing section that performs each of the processes in accordance with the combination set by the process setting section, wherein: a value of a counter indicative of an order and a combination of the image processing to be performed is set for each of the plurality of unit cycles; and the processing section performs each of the processing for each of the plurality of unit cycles sequentially in accordance with the priority and the set value of the counter.
