An image processing portion () performs binarization, segmentation, and feature extraction of a received image using a RAM (), compares the extracted feature with specific pattern data stored in a dictionary data memory (), performs recognition processing, and provides recognition results to a CPU (). The dictionary data memory is a volatile memory, in which specific pattern data held by the CPU is written by the CPU when power is turned on. Since the data stored in the volatile memory is erased when power is turned off, the dictionary data memory can be removed and the contents are analyzed when the power is turned off without causing any trouble.

Image recognition apparatus

On a circuit boardthere are provided, other than a comparison circuitmounting region, dictionary ROM mounting regionsandand microprocessor mounting regionsandwith an address busand a data buseach connected to mounting regionsandin parallel and to mounting regionsandin parallel. Initially, a dictionary ROMand microprocessorare mounted on mounting regionsandrespectively, and when the current version is to be upgraded a dictionary ROMhaving dictionary data partially changed to do so is mounted in mounting regionand a microprocessorhaving a program partially changed to do so is mounted in mounting regionConsequently, there can be provided an image processing device that can ensure a high level of mounting-strength and can also readily allow for exchanging a component thereof and upgrading its version.
