Abstract: A biometric information acquisition device includes a camera configured to capture an image of a hand of a user inserted into an imaging space, an illumination configured to illuminate inside of the imaging space from above, a housing configured to accommodate the camera and the illumination, and a first opening formed by cutting out a part of the housing and provided in a rectangular shape in a front view to form the imaging space.

Abstract: This biological information acquisition device comprises: a first camera which captures a first hand image of a user, the hand being inserted into an imaging region; a second camera which captures a second hand image of the user used for biological authentication; and a processor which causes the second camera to capture the second hand image when a stop of the user's hand is detected on the basis of the hand image captured by the first camera.

Abstract: This endoscope is provided with: a hard part that is provided at the distal end of a scope, is formed in a substantially cylindrical shape, and has a substantially circular distal end surface; and a plurality of cameras that are disposed on the left and right sides of the hard part to be located on both sides of a first virtual line perpendicular to the axis of the hard part on the distal end surface. The plurality of cameras include a first camera. The first camera is disposed so that the imaging axis is offset in the direction along the first virtual line from a second virtual line perpendicular to the axis and the first virtual line.
