Abstract: A light source control device for an endoscope includes one or more processors that perform processes. The processes include: (1) generating a light quantity control signal indicating excess or insufficiency of an illumination light quantity based on an imaging signal from an imaging element (2) determining whether the endoscope is left based on the light quantity control signal and whether the illumination light quantity is equal to or greater than a predetermined quantity; and (3) setting a control range that limits the illumination light quantity based on the light quantity control signal, wherein the setting the control range includes setting a second range having an upper limit lower than an upper limit of a first range as the control range, when the processors determine that the endoscope is left in a state in which the first range is set as the control range.

Abstract: An image processing device is configured to obtain first-type image data and second-type image data generated as a result of taking images of same photographic subject from different directions, and generate a parallax image based on the first-type image data and the second-type image data. The image processing device includes a processor comprising hardware. The processor is configured to: set an image selection mode in which an image is selectable based on an image displayed in a display; superimpose a frame data onto image data to be displayed in the display when the image selection mode is set, the frame data representing a boundary area whose size is set based on an optical system that forms an image of the photographic subject; and obtain the first-type image data and the second-type image data corresponding to selected image when the image selection mode is set.
