Abstract: An awakening effort motion estimation device includes processing circuitry configured to acquire a captured image obtained by imaging an occupant's face in a vehicle; detect, on a basis of the captured image having been acquired, two reference points for estimating a motion of the occupant's mouth, the two reference points including one point on a mask worn by the occupant, and the other point being a point based on a feature point of the occupant's face or a point different from the one point on the mask in the captured image; calculate a reference point distance between the detected two reference points; and estimate whether or not the occupant is performing an awakening effort motion by moving his or her mouth depending on whether or not the calculated reference point distance satisfies an awakening effort estimating condition.

Abstract: An image capture device of the present invention includes: a zoom lens being caused by the operation of the zoom mechanism to move along the optical axis; an information acquisition part which acquires information about the amount of movement determined by the amount of movement of the zoom lens; a power supply part which supplies power to the information acquisition part; a controller which controls power supply; and a state detection part which detects a specific halt state in which the zoom mechanism stops the movement of the zoom lens when the zoom mechanism is in a predetermined operating position, the predetermined operating position being such that the zoom lens hardly changes its position despite the action of external force. The controller stops power supply from the power supply part to the information acquisition part when the state detection part detects the specific halt state.

Abstract: In a disk identifying device, when a slanting reflecting face is irradiated with light emitted from a light emitting element while a rotary tray is rotating, most of the light reflected from the slanting reflecting face is not incident on a light receiving element, whereas when a flat reflecting face is irradiated with the light emitted from the light emitting element, most of the reflected light is incident on the light receiving element. Since the receiving element receives the reflected light in a pattern corresponding to an assigned number of a pertinent disk placing portion, the rotary position of the rotary tray is detected. Where a disk detecting hole is irradiated with the light emitted from the light emitting element, the presence or absence of a disk on the pertinent disk placing portion is detected by the presence or absence of the reflected light received by the light receiving element.
