ENDOSCOPE APPARATUS AND METHOD FOR CONTROLLING ENDOSCOPE APPARATUS

摘要

An endoscope apparatus includes a processor including hardware. The processor is configured to implement an image acquisition process that acquires a plurality of in vivo images; an in-focus evaluation value calculation process that calculates an in-focus evaluation value that represents a degree of in-focus corresponding to each of the plurality of in vivo images; a focus control process that controls a focus operation of an imaging optics by performing a control process that switches a position of a focus adjustment lens included in the imaging optics between a plurality of discrete positions based on the in-focus evaluation value; and a freeze image setting process that selects at least one in vivo image from the plurality of in vivo images based on the degree of in-focus represented by the in-focus evaluation value, and sets the selected at least one in vivo image to be a freeze image.

1. An endoscope apparatus comprising:
a processor comprising hardware, the processor being configured to implement: an image acquisition process that acquires a plurality of in vivo images that were obtained by capturing an in vivo object using imaging optics, each of the plurality of in vivo images including an image of the in vivo object; an in-focus evaluation value calculation process that calculates an in-focus evaluation value that represents a degree of in-focus corresponding to each of the plurality of in vivo images; a focus control process that controls a focus operation of the imaging optics by performing a control process that switches a position of a focus adjustment lens included in the imaging optics between a plurality of discrete positions based on the in-focus evaluation value; and a freeze image setting process that selects at least one in vivo image from the plurality of in vivo images based on the degree of in-focus represented by the in-focus evaluation value, and sets the selected at least one in vivo image to be a freeze image.
