Claim 6:
7. A data processing device with a monitor for evaluating a degree of severity of a lesion in an organ from a plurality of images of a living tissue in the organ, comprising:
an image evaluation value calculation unit configured to calculate an image evaluation value indicating the value of the intensity of a parameter of the lesion of the living tissue in each of the plurality of captured images of the living tissue inside the organ;
an imaging position information processing unit configured to associate each of the images with information of an imaging position in the organ in which each of the images is captured;
a lesion evaluation unit configured to calculate a representative evaluation value of the image evaluation values of the plurality of captured images of the living tissue for each of a plurality of sections in which a captured image of a region in the organ is divided using the information of the imaging position so as to evaluate the length of the lesion which is continuously extends in a depth direction of the organ; and
a monitor configured to display an evaluation result of evaluating the extent of lesion on a screen, wherein
the lesion evaluation unit is configured to determine the presence or absence of a lesion portion in which the lesion continuously extends in the depth direction of the organ for each section based on the representative evaluation value,
the evaluation unit includes a lesion position calculation unit which is configured to obtain a section where the lesion portion is located among the sections based on information of the imaging position so as to obtain a start position and an end position of a region of the lesion portion,
the lesion evaluation unit is configured to calculate the length of the lesion portion from the start position and the end position of the lesion portion, and
the monitor is configured to display at least one of the start position of the region of the lesion portion, the end position of the region of the lesion portion, and the length of the lesion portion on the screen.
