IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

The invention provides the image processing device that can shorten a time required for setting a parameter. The invention provides the image processing device that searches an input image for a feature amount based on a feature amount included in a model image. The image processing device includes: the hardware for holding a feature amount of a feature portion of the model image; the search-range reception module for receiving a setting value indicating a size of a range of searching the input image for a feature amount corresponding to the feature amount of the model image; the search-range determination module for determining, by using the setting value, a range of searching the input image for a feature amount corresponding to a feature amount of the model image; and the display module, in superposition with the model image, a search range determined by the search-range determination module.
