摘要： An auto-focusing system includes a focus condition detector which detects the focus condition based on infrared light. A data producer is provided for producing a deflection signal indicating the difference between an image forming distance for infrared light and that for visible light, due to aberration. In accordance with the detected focus condition and deflection signal, an objective lens is shifted to a position for properly focusing an image of visible light on an image forming plane.

摘要： In an interchangeable lens including an optical system adjustable for focusing and adapted to be detachably mounted on a camera body which is provided with focus detection means for detecting an amount of defocus of an object image formed by the optical system, and drive means for driving the optical system for the focus adjustment thereof in accordance with the detected amount of defocus. The interchangeable lens comprises, inter alia, a code plate for producing a plurality of digital photographic distance signals representing given discrete photographic distances of the optical system in accordance with the adjustment of the optical system for focusing. Circuit means output a predetermined one of a plurality of inputs, the plurality of outputs including a plurality of conversion coefficients needed for converting the detected amount of defocus into the amount of drive to be effected by the driving means, the conversion coefficients being intrinsic to the interchangeable lens and having values depending upon the discrete photographic distances of the optical system represented by the digital photographic distance signals, respectively.The digital photographic distance signals are applied to the circuit means as the predetermined input to cause the circuit means to output one of the conversion coefficients as the predetermined output, the value of which depends upon the photographic distance of the optical system represented by the one digital photographic distance signal being produced. The output conversion coefficient are transmitted to the camera body.

摘要： A lighting device such as an electronic flash device attachable to a camera body includes first and second light projecting optical systems which project first and second light fluxes for illuminating an object to aid focus detection by a focus detection device. The second light flux spreads at a larger solid angle than the first light flux and illuminates a first distance zone which extends to a closer distance side while covering the whole of a second distance zone illuminated by the first light flux. An optical wedge disposed in the second light projecting optical system deflects a part of the second light flux towards the closer distance side of the first distance zone. Another lighting device includes a single light projecting optical system but it also includes an optical wedge for deflecting a part of a light flux projected by the light projecting optical system to widen a distance zone illuminated by the light flux towards a closer distance. The optical wedge also serves to produce a difference in intensity distribution of the light flux such that the light flux has higher intensity at a part thereof for illuminating a farther distance side of the distance zone than at a part thereof for illuminating a closer distance side of the distance zone. A light source of the light projecting optical system(s) is provided with a conical light reflecter surrounding a light emitting diode to reflect light emitted from side surfaces of the light emitting diode forward.

摘要： In a biometrics system for a building entrance unlocking or a bank account authentication, reference information registered under administration by the system is transmitted to a room or mobile-phone for private storage, with the original reference information deleted from the system. Biologic information gotten upon authentication is transmitted through wireless system to the room or mobile-phone for comparison with the reference, the result being returned to the system. Or, the reference is tentatively sent back to the system for comparison with the gotten biologic information. The biologic information sent to mobile-phone also includes health control information for storage and display. Mobile-phone also can receive blood pressure information at a waiting lounge of medical institution though wireless local communication even if the main power shut down. The communication between the biometrics system and the mobile-phone is encrypted. The system includes sensor unit and protection unit, the abnormality thereof being separately checked.

摘要： In response to an operation such as power-on or power-off, channel change and sound volume change, a television set combined with a personal computer automatically makes e-mail with information in a predetermined format indicative of the operation attached. The e-mail is automatically sent to another television set to inform the other television set of operation of the own television set. On the other hand, the e-mail can be sent to a rating company for audience share survey. The television set automatically reads the received e-mail and attachment to change the indication of display. The television set has storage of the received information for analysis of an abnormality. Abnormality can be also sensed through abnormal act on the remote controller apt to be taken by a person in panic or off the truck. The television set refuses information from unknown address for blocking an attack of a stranger.
