Abstract: A sitting height estimation ECU is mounted on a vehicle and includes: an acquisition unit configured to acquire an image of a driver sitting in a driver's seat; a position detection unit configured to detect a position of a landmark on a face of the driver from the image; a crown estimation unit configured to estimate a position of a crown of the driver on the basis of the position of the landmark; and a sitting height estimation unit configured to estimate a sitting height of the driver on the basis of an estimation result obtained by the crown estimation unit.

Abstract: A camera head includes an airtight case which includes an image pickup unit having an image pickup device and the like as a heat source in an inner portion and includes a partition wall to secure air-tightness with respect to an outside of the airtight case, a heat transfer sheet which connects the heat source and an inner surface of the partition wall to transfer heat generated at the heat source to the partition wall, a heat sink arranged on an outer side of the partition wall of the airtight case, and a spring member which is interposed between an outer surface corresponding to the inner surface of the partition wall of the airtight case connected to the heat transfer sheet and the heat sink to transfer heat from the outer surface of the partition wall to the heat sink.

Abstract: An image pickup apparatus for an endoscope includes an exterior member; an internal unit including an image pickup unit; a fixing frame formed of metal and including at least one fixing portion configured to retain the internal unit and to fix the internal unit to an inner surface of the exterior member; and a washer provided between the at least one fixing portion and a screw hole of the inner surface, the washer being formed of a member with a lower thermal conductivity than metal, wherein the at least one fixing portion of the retaining member is fixed to the fixing part of the exterior member by a fixing member via the heat insulating member, and the heat insulating member covers an outer circumference of the fixing member.
