Patent ID: 8447076

Claim:
An image processing method comprising: a clipping step of clipping respective partial images from a plurality of predetermined areas in an object image, a first calculating step of calculating difference values of pixel values between a target pixel and surrounding pixels surrounding the target pixel in the partial image clipped in the clipping step, a deciding step of deciding a parameter value for each of the surrounding pixels based on a predetermined area from which the partial image has been clipped in the clipping step, the difference value between the target pixel and the surrounding pixel, and a position of the surrounding pixel relative to the target pixel, a second calculating step of calculating a feature amount corresponding to the target pixel using the parameter values for the surrounding pixels, and a creating step of creating a feature amount image for each of the partial images by assigning the feature amount calculated with respect to each target pixel in the partial images as a pixel value of the feature amount image; wherein in the creating step, the result of adding all the parameter values decided in the deciding step for one target pixel is set as the feature amount for the target pixel.
