A plurality of depth information are extracted from image sensing related information sensed by the camera at the plurality of coordinate positions, and the plurality of extracted depth information are converted and unified into depth information expressed by a unified coordinate system.

Abstract: An image sensor head having a CCD is rotatably attached to a card body having a computer interface. A DC/DC converter for supplying the image sensor head with electric power is provided so as to be situated outside and external device, such as a computer, when the card body is loaded in the external device. This facilitates the radiation of heat. A shielding case is provided to cover and shield the DC/DC converter. When the card body experiences deformation, the shielding case contacts a metal cover which covers a main board within the card body, thereby preventing excessive bending and assuring electrical safety. Thus, in a card-type image sensor of the type which introduces an image to a computer or the like, the power supply for image sensing purposes radiates heat more effectively and is provided with improved shielding.

Abstract: An image pickup apparatus comprises image pickup means for converting an object image formed on an image pickup surface to an image signal and object information detection means for detecting information associated with the object. Control means for determines a dividing number of areas into which the object image to be picked up by the image pickup means is to be divided on the basis of the information from the object information detection means and controls the image pickup means to perform the image pickup operation of the object image by executing image pickup operations a number of times, the number of times being equal to the dividing number. Preferably, the information detection means detects at least one of a size and a density of the object.

Abstract: For providing a compact, light, and cheap image pickup apparatus capable of attaining both a stereoscopic image and a high-definition plane image by itself, a changeover optical unit is provided with both a function to attain a stereoscopic image by guiding beams captured through objective lenses to respective CCDs and a function to attain a plane image by splitting the beam captured through the objective lens into two beams and guiding the two beams to the CCDs whereby the stereoscopic image and the high-definition plane image can be attained by proper changeover between these functions.

Abstract: To realize a multi-eye image pickup apparatus which can perform proper exposure for each of a plurality of image pickup devices, the multi-eye image pickup apparatus having a plurality of image pickup devices is arranged to have an exposure amount controlling device provided for each of the image pickup devices, for controlling an exposure amount, and a control unit for determining an exposure amount of each exposure amount controlling device, based on photometric values of pickup images obtained by the plurality of image pickup devices or based on photometric values of split images obtained by splitting each of the pickup images into a plurality of zones.

Abstract: In a multi-eye image pick-up apparatus, an optical axis angle controller sets the optical axes of first and second video camera portions at predetermined optical axis angles when a power supply voltage for allowing an image pick-up operation is supplied. When the optical axes of the first and second video camera portions do not cross each other at a position in front of the apparatus, in-focus detection is performed using an overlapping region between image pick-up regions of the first and second video camera portions.

Abstract: An image pickup apparatus comprising plural image taking systems for taking the image of an object and outputting image signals, a memory circuit for storing plural image signals output from the plural image pickup systems, a convergence angle setting unit for setting the convergence angle of the plural image pickup systems, and a trimming circuit for extracting, from each of the plural image signals stored in the memory circuit, the signal of a portion corresponding to the convergence angle set by the convergence angle setting unit.

Abstract: A disc drive device which comprises a negative-pressure pad for generating a negative pressure between the negative-pressure pad and a disc-shaped recording medium by the rotation of the disc-shaped recording medium and a displacement member for bringing the negative-pressure pad and a surface of the disc-shaped recording medium close to each other at least once after the disc-shaped recording medium has started to rotate.

Abstract: The disclosed electro-mechanical transducing element has an elongated shape and is mechanically deformable in response to a supplied electrical signal. One or more electrically conductive portions are formed to run along the direction of elongation to form one or more electrical paths for one or more electrical members which are to be affixed to a portion or portions near the free end of the elongated element. According to a disclosed embodiment the electrical member or members are mechanically moved through mechanical deformation of the element. Electrical lead wires are connected to the electrically conductive portions at the first end of the element opposite the free end, thereby eliminating the influence of the lead wires on the deformation performance of the element.

Abstract: A mechanism for opening and closing the shutter of a magnetic disc cassette as the cassette is loaded to and unloaded from a cassette holder. A resilient plate is fixed at one side to the cassette holder and its other or free side is provided with a resilient strip that extends along an adjacent side edge of the cassette holder. This resilient strip is provided with a friction member arranged to engage in frictional contact with the shutter of the cassette. The thickness of the friction member is wider than the thickness of the cassette. A stopper for the free end of the resilient strip is carried on the cassette holder.

Abstract: The disclosed magnetic recording and/or reproducing apparatus uses a disc-shaped magnetic recording bearing medium having a magnetizable member mounted at its center. The apparatus includes a recording and/or reproducing magnetic head and a spindle for rotating the record bearing medium. The spindle is provided with a permanent magnet for attracting the magnetizable member of the medium. The permanent magnet is magnetized in a radial direction of the spindle.

Abstract: There is provided a motor having a frequency generator comprising a frequency generating base plate on which a frequency generating coil pattern and a land are formed, in which a signal of the frequency proportional to the rotational speed of a rotary driving apparatus which is generated from the frequency generating coil pattern is output from the land to another base plate. The land is formed in the frequency generating coil pattern.

Abstract: A disc handling apparatus having a motor for rotating a disc for signal recordation and/or reproduction including a device for insuring that the ejection of the disc from a recording and/or reproducing position is enabled after the rotation of the disc by the motor is stopped by a brake.
