Endoscope apparatus, method of operating endoscope apparatus, and recording medium
First Claim
1. An endoscope apparatus comprising:
- an imaging element configured to generate imaging signals by imaging a subject and include a plurality of pixels disposed in a matrix pattern, an imaging area in which the plurality of pixels are disposed including a scanning area, the imaging signals being read from at least a part of the pixels of each row in the scanning area;
a video signal generating circuit configured to generate video signals from the imaging signals;
an illuminator comprising a light source configured to generate illumination light emitted to the subject; and
one or more processors comprising hardware, wherein the one or more processors are configured to;
control the imaging element and the illuminator in accordance with a set operation mode among a plurality of operation modes, the plurality of operation modes comprising a first operation mode and a second operation mode;
control the illuminator such that the light source is continuously controlled to be turned on in exposure periods of all of the pixels disposed in the scanning area, in a case in which the first operation mode is set;
control the imaging element such that at least parts of the exposure periods of the pixels disposed in at least a part of the scanning area overlap each other, in a case in which the second operation mode is set; and
control the illuminator such that the light source is turned on in a period in which at least parts of the exposure periods of the pixels disposed in at least a part of the scanning area overlap each other, in a case in which the second operation mode is set.

Abstract
An endoscope apparatus includes an imaging element, a video signal generating circuit, an illuminator, and one or more controllers. An imaging area in which a plurality of pixels are disposed includes a scanning area. In a case in which a first operation mode is set, the one or more controllers control the imaging element such that at least parts of the exposure periods of the pixels disposed in at least a part of the scanning area overlap each other. In a case in which a second operation mode is set, the one or more controllers control the illuminator such that the light source is turned on in a period in which at least parts of the exposure periods of the pixels disposed in at least a part of the scanning area overlap each other.
