IMAGE PROCESSING APPARATUS, IMAGE PROCESSING PROGRAM RECORDING MEDIUM, AND IMAGE PROCESSING METHOD
First Claim
1. An image processing apparatus comprising:
- a category area dividing unit that divides each image constituting time-series images of an object to be examined, which are captured in time series, into category areas including an examined area and an abnormal candidate area, the examined area showing the object to be examined, the abnormal candidate area being possibly an abnormal area showing an abnormal site of the object to be examined;
an optical flow calculator that calculates optical flows of the examined area and the abnormal candidate area from images constituting the time-series images; and
an abnormal area detector that compares the optical flow of the examined area and the optical flow of the abnormal candidate area, and detects the abnormal candidate area as the abnormal area according to the result of the comparison.

13. An image processing program recording medium having stored thereon instructions that causes an image processing apparatus to perform:
-
a category area dividing procedure that divides each image constituting time-series images of an object to be examined, which are captured in time series, into category areas including an examined area and an abnormal candidate area, the examined area showing the object to be examined, the abnormal candidate area being possibly an abnormal area showing an abnormal site of the object to be examined; an optical flow calculating procedure that calculates optical flows of the examined area and the abnormal candidate area from images constituting the time-series images; and an abnormal area detecting procedure that compares the optical flow of the examined area and the optical flow of the abnormal candidate area, and detects the abnormal candidate area as the abnormal area according to the result of the comparison.

14. An image processing method comprising:
-
a category area dividing step that divides each image constituting time-series images of an object to be examined, which are captured in time series, into category areas including an examined area and an abnormal candidate area, the examined area showing the object to be examined, the abnormal candidate area being possibly an abnormal area showing an abnormal site of the object to be examined; an optical flow calculating step that calculates optical flows of the examined area and the abnormal candidate area from images constituting the time-series images; and an abnormal area detecting step that compares the optical flow of the examined area and the optical flow of the abnormal candidate area, and detects the abnormal candidate area as the abnormal area according to the result of the comparison.
