Abstract

An image processing apparatus have a processor configured to: receive a plurality of images of a tissue including a lesion portion, the plurality of images being received from an endoscope; judge, based on a signal from the endoscope, whether or not to engage a differentiation classification operation; in response to judging that the differentiation classification operation is engaged, process the plurality of images to specify the lesion portion within one or more of the plurality of images; and perform differentiation classification on the one or more images to classify the lesion portion into at least one class of a plurality of classes; and in response to judging that the differentiation classification operation is not engaged, not process the plurality of images to specify the lesion portion within the one or more of the plurality of images.

Claims14

Dependent claims

An image processing apparatus comprising:

a processor comprising hardware, wherein the processor is configured to:
receive a plurality of images of a tissue including a lesion portion, the plurality of images being received from an endoscope operated by an operator;
judge, based on a signal from the endoscope, whether or not to engage a differentiation classification operation to classify the lesion portion in one or more of the plurality of images;
in response to judging that the differentiation classification operation is engaged,
process the plurality of images to specify the lesion portion within the one or more of the plurality of images;
and
perform differentiation classification on the one or more images in which the lesion portion is specified to classify the lesion portion into at least one class of a plurality of classes;
and
in response to judging that the differentiation classification operation is not engaged, not process the plurality of images to specify the lesion portion within the one or more of the plurality of images, and
wherein the processor is configured to:
judge, based on the signal from the endoscope, whether or not a distal end of an insertion section of the endoscope is still;
in response to judging that the distal end of the insertion section is still, judge that the differential classification operation is engaged;
and
in response to judging that the distal end of the insertion section is not still, judge that the differential classification operation is not engaged.
