Abstract
This invention provides an image processing device and an image processing method capable of implementing pattern matching based on an edge code at relatively high speed with a smaller circuit configuration. In the image processing device according to the present embodiment, an information amount of a valid zone is diffused over an entire edge code image. In other words, the amount of information used in the entire edge code image is compressed by reducing the number of bits to assign to each pixel and effectively using the number of bits assigned to each pixel as a whole. If a valid zone for an edge EDG, the following invalid zone in which the invalid edge code value continues, and the following valid zone for an edge EDGappear in a profile of the edge code value, increase/decrease information from the edge code value contained in the valid zone for the edge EDGto the edge code value contained in the valid zone for the edge EDGis assigned to the element corresponding to the invalid zone.
