PROBLEM TO BE SOLVED: To enable the discrimination and collection of an image not to be affected by the body action or the like of a reagent by extracting the contour information of an object from respective frame images, for which an ultrasonic moving image is partitioned at prescribed time intervals, and comparing respective pieces of that information. SOLUTION: When the moving images of the heart outputted from an ultrasonograph 100 are successively inputted to an image input part 201, an extraction part 202 extracts its contour from the respective inputted images. At an information dividing part 203, the extracted time sequential information of the heart contour is divided at every sampling time set based on the information of a heartbeat measured value inputted from the outside, for example, and temporarily stored in an information storage part 204. At a comparative discrimination part 205, respective divided pieces of heart contour information are compared so as to discriminate an image effective for diagnosis, and the image discriminated as effective is stored in the information storage part 204. An output part 206 time sequentially displays the compared results at the comparative discrimination part 205 or reads the moving image discriminated as effective out of the information storage part 204 and displays it. |
