US 11,992,177 B2 · Image processing device for endoscope, image processing method for endoscope, and recording medium

Abstract

An image processing device for an endoscope includes a processor. The processor receives, as input, a generated image acquired by performing predetermined processing on an image pickup signal acquired by an endoscope, analyzes a withdrawing speed of the endoscope based on at least one of the generated image and information relating to an operation state of the endoscope, detects a lesion part from the generated image, performs a diagnosis support action on the lesion part, decides a factor affecting the diagnosis support action based on an analysis result of the withdrawing speed, and outputs the factor.

Dependent claims

An image processing device for an endoscope, comprising:

a processor configured to:
receive a generated image generated from an image of an object captured by an endoscope;
calculate a withdrawing speed of the endoscope based on at least one of the generated image and sensor information relating to an operation state of the endoscope;
detect a lesion part that is an observation target from the generated image;
perform a diagnosis support action of adding support information to the generated image in which the lesion part was detected;
determine whether the withdrawing speed of the endoscope is within a predetermined range;
and
in response to determining that the withdrawing speed of the endoscope is not within the predetermined range, determine that the lesion part cannot be detected or is erroneously detected, and control a display to display a warning content that the diagnosis support function is not performed normally.
