Endoscope apparatus

An endoscope apparatus comprising:

• a processor configured to:
• sequentially receive observation images of a subject and detect a characteristic region in the observation images based on a predetermined feature value;
• determine a time when the characteristic region is detected in the sequentially received observation images;
• determine an elapsed time period from the time when the characteristic region is detected in the sequentially received observation images;
• selectively apply a predetermined emphasis processing to one or more images of the observation images to emphasize a position of the characteristic region in the one or more images of the observation images,
• wherein in response to determining that the elapsed time period is less than a first predetermined time period, the processor is configured to not apply the predetermined emphasis processing to one or more images of the observation images received during the elapsed time period, and
• wherein in response to determining that the elapsed time period is equal to the first predetermined time period, the processor is configured to apply the predetermined emphasis processing to one or more images of the observation images received after the first predetermined time period;
• and
• control a monitor to display the observation images having the predetermined emphasis processing selectively applied to one or more of the observation images.
