Abstract: An image projection device includes an acquiring unit configured to acquire a first ratio of a second distance to a first distance. The first distance is a distance between a projecting unit that projects a projection image and a first point in a projection area on which the projection image is projected. The second distance is a distance between the projecting unit and a second point in the projection area. The image projection device also includes an estimating unit configured to estimate, using the first ratio, light/dark levels of respective division areas into which the projection area is divided; and a light/dark-level processing unit configured to perform light/dark-level processing on areas in the projection image corresponding respectively to the division areas in accordance with the corresponding light/dark level.

Abstract: A focus adjusting method for adjusting focus by moving a focusing lens group of a photographing optical system, wherein the focus adjusting method includes a first search stage at which a focus search operation is performed based on an image formed in a large focus area while the focusing lens group is moved stepwise over an entire range of movement thereof from the near extremity to the far extremity, and a second search stage at which the focus search operation is performed, based on images formed in small focus areas, at front and rear close vicinities of the in-focus position while the focusing lens group is moved stepwise over a portion of the entire range of movement thereof.

Abstract: Solid state power controllers are described that include a switch controlled by a microcontroller and communication contacts. In one aspect of the invention, the microcontroller is galvanically isolated from the communication contacts using magnetoresistive isolation. In another aspect of the invention a number of solid state power controllers are connected to an external microcontroller to form a power distribution array. In addition, messages exchanged between the external microcontroller and the solid state power controllers can be used to configure the solid state power controllers and provide a user interface.

Abstract: A phase difference sensor is arranged toward a target object such that the sensor can rotate at least 180° on its sensor optical axis. As the phase difference sensor rotates, the angle of a sensor viewing field is changed, and the distance to the target object is correctly computed using results measured before and after the change in the angle.

Abstract: A digital camera has distance measurement zone setting means (12) for dividing distance to a subject into a plurality of distance measurement zones; distance measurement zone selection means (13) for selecting a distance measurement zone to be scanned; an autofocus evaluation value calculation circuit (14) for acquiring an AF evaluation value by scanning the selected distance measurement zone; zone-update determination means (15) for determining, through use of the AF evaluation value, whether or not to update a distance measurement zone to be scanned; and in-focus position decision means (16) for appropriately updating the scanned distance measurement zone based upon the determination as to whether to update the distance measurement zone, and deciding an in-focus position based upon acquisition of AF evaluation value. A focusing lens (2) is driven to the in-focus position by a focusing-lens drive circuit (17).

Abstract: This invention provides an automatic framing camera that identifies a still subject, frames it, and photographs it. The ranging direction of a ranging unit (light emitting element and light receiving element) that can range in one direction is changed by a pan motor and a tilt motor, and a still person is searched for by changes in the signal from the ranging unit. Then, the photography direction of the imaging element is turned by the tilt motor toward the center of the face of the person that was found, this is framed with the center of the person's face in the center of the angle of view, and the person's face is photographed by the imagining component.

Abstract: Stereoscopic device including a lenticular lens layer and light sensor array, the lenticular lens layer includes a plurality of lenticular elements, the sight sensor array includes a plurality of light sensors, wherein selected ones of the light sensors detect light at a predetermined range of wavelengths and wherein at least selected others of the light sensors detect light at at least another predetermined range of wavelengths and wherein each of the lenticular elements is located in front of a selected group of the light sensors, thereby directing light from different directions to different light sensors within the selected group of the light sensors.

Abstract: A method of detecting a focus position of a projection optical system at a high throughput and with high accuracy. A sensor pattern (SP) which is provided on a wafer stage (WS) as a light-receiving part of a photoelectric sensor (PES) is moved in the direction of an optical axis (AX) of a projection optical system (PL), and at the same time, it is moved in a direction (X) perpendicular to the optical axis (AX). While doing so, a reticle pattern (RP) which is provided on a reticle (R) is illuminated by illuminating light (IL) for exposure, and an image of the reticle pattern (RP) is formed on the sensor pattern (SP) through the projection optical system (PL). Light passing through the sensor pattern (SP) is received by the photoelectric sensor (PES), and a focus position is detected on the basis of the intensity of the transmitted light.
