Abstract: A mechanism enabling reduction of the size of a structure for mounting an image pickup device without affecting the amount of movement of an optical system even when screw insertion holes of a sensor plate are arranged closer to the optical axis. The sensor plate of an image pickup apparatus is mounted to a lens barrel with screws, and includes an attachment surface to which the image pickup device is attached and contact surfaces which are fixed to the lens barrel. The attachment surface is protruded from the contact surfaces. By bringing the attachment surface to the lens barrel in the optical axis direction, the device has an image pickup surface positioned with respect to the lens barrel in the optical axis direction. The sensor plate has an opening formed between the attachment surface and each contact surface, for absorbing deformation of the sensor plate.

Abstract: A three-dimensional map distribution server device stores shape data for structures drawn on a ground to generate a three-dimensional map image, and, in the first place, transmits to a client PC a list which includes shape data for structures in a district and has position information of the district or of the structures. The client PC selects shape data required for the display based on the position information in the list, and transmits a transmission request for the selected shape data to the three-dimensional map distribution server device. When receiving the request, the three-dimensional map distribution server device responds and transmits to the client PC the requested shape data.

Abstract: Video signals that are reproduced or processed are outputted to a first video image display device. An illuminance detection section detects the ambient illuminance during the output of the video signals. In the case that the detected illuminance is equal to or greater than a predetermined threshold, the reproduced or processed video signals are outputted to a second video image display device which provides a display with lower brightness than that for a display provided by the first video image display device.
