    摘要: An image processing apparatus for effecting a series of processes for capturing an image and scrutinizing the captured image is disclosed. Each process in series of processes is selected from different modes of processes. Selector selects a mode of process for each of the series of processes. A preselected number of parameters are set for each of the selected mode of processes, and the set parameters are stored in a parameter memory sequentially. Mode data indicative of the selected modes for the series of processes are stored in the mode memory. A parameter number table informs the number of parameters necessary for each mode in each of the series of processes. When the parameters and the mode data are read from the parameter memory and said mode memory, respectively, parameter allocator allocates and produces proper parameters to corresponding modes of processes with reference to the parameter number table.
