摘要： The present invention discloses an image-projecting apparatus which employs an AF (auto-focusing) system suitable for use conditions of the image-projecting apparatus and is capable of securing satisfactory AF accuracy under bright conditions. The image-projecting apparatus comprises a projection optical system which projects light from an image-forming element onto a projection surface, and a detecting system which performs a detecting operation of a distance to the projection surface or a detecting operation of a focusing state of the projection optical system with respect to the projection surface. The detecting system determines a condition of the detecting operation on the basis of the light-receiving intensity level of the light-receiving element which receives reflected light from the projection surface of light projected and performs the detecting operation in accordance with the condition.

摘要： A projection type image display apparatus capable of achieving accurate focusing of a projection optical system using an output from a photoreception sensor, is disclosed. The projection type image display apparatus includes a projection optical system and performs focusing control of the projection optical system based on an output signal from an photoreception sensor. The photoreception sensor receives light from the projection surface. The optical axis of the projection optical system is shifted with respect to a reference axis. The reference axis leads from the center of an original image formed on an image forming element to the center of the projected image. The photoreception sensor receives light from a detection area which is proximate to and includes the position of the optical axis of the projection optical system on the projection surface.

摘要： A PC card camera has a structure in which a universal joint to which a video camera is attached is mounted on a PC card body. The video camera comprises an optical lens unit and a solid-state area sensor of the photoelectric transducer type. The universal joint holds the video camera in such a manner that the angular position thereof can be adjusted freely with respect to the PC card. The PC card body is provided with a guide for guiding the card into a slot provided in a personal computer, a connector for connecting the PC card to the personal computer, and a cut-out which prevents the PC card from being inserted incorrectly. With the PC card connected to the personal computer, the angular position of the video camera can be adjusted via the universal joint.
