METHOD AND DEVICE FOR IMAGE PROCESSING

PROBLEM TO BE SOLVED: To reduce the capacity of a memory, to make the response of display and processing fast, and to make it easy to grasp the whole image and improve operability by specifying feature points in an original image of high resolution and storing the coordinates of the feature points as feature point coordinate data. SOLUTION: The original image 1 and two points in two dotted-line rectangular frames 2a and 2b are specified as feature points 3a and 3b and (x1, y1) and (x2, y2) are obtained as feature point coordinate data. The respective data are shown typically as coordinate data of high precision like 'x1: xxx, xxx' and 'yl: yyy, yyy'. The coordinate data are data on the coordinate system of the original image and can be found as the row numbers and column numbers of pixels at the feature points from the product of the size of pixels while the original image is regarded as a pixel matrix. As the origin coordinates of the original image, the position of pixel data taken out of a data file of the original image for the 1st time or a specified pixel, etc., is used as the origin coordinates of the original image.
