摘要： An active distance measuring apparatus is equipped with a light projector for projecting modulated light to an object, a photoreceptor for receiving the modulated light reflected from the object and generating an alternating signal corresponding to the distance to the object, and a signal processing circuit for generating distance data from the alternating signal. The signal processing circuit is constituted by high level detecting means for detecting the high level value of the alternating signal, low level detecting means for detecting the low level value of the alternating signal, and an operation means for calculating distance data from the difference of both level values.

摘要： A power supply device includes a voltage output unit configured to output a DC voltage corresponding to a control signal from a first controller and an output evaluator configured to perform a judgment process of judging whether or not the DC voltage is a voltage corresponding to a set value received from the fist controller, and to output a result of the judgment to the first controller. The output evaluator includes a storage for storing correspondence information which shows a correspondence relationship between the set value and a voltage value of the DC voltage outputted from the voltage output unit. The output evaluator performs the judgment process by outputting the correspondence information to the first controller, and receiving a set value determined on the basis of the correspondence information from the first controller.

摘要： A camera capable of operating in a standard or a panoramic photography mode is provided with an automatic focusing system that focuses on a subject in one of a plurality of areas within a photographic field. In the standard photography mode, the camera automatically selects one of the plurality of areas based on a predetermined algorithm and focuses on the selected area. In the panoramic photography mode, the camera selects one of the plurality of area in response to a user performed operation and focuses upon the selected area. When operating in the panoramic photographic mode, an area can be selected by using a manual selection device, or through use of a visual line position detection device. The visual line position detection device determines which area in the photographic field the photographer's eye is focused upon, and the focused upon area is then selected. The camera may include a display device that indicates which of the plurality of areas has been selected.

摘要： In a camera system including an electronic flash apparatus, a main capacitor of the flash apparatus is charged for a predetermined time interval, in response to a preparatory operation such as a first stroke of a release button. During this time interval, operation of an automatic distance measuring device, an automatic exposure controlling device and an object luminance discriminating circuit is prevented. A warning device warns a photographer that the main capacitor is insufficiently charged. Several voltage detectors detect different voltage levels of the main capacitor and produce detection signals for inhibiting the operation of the warning device and/or preventing further charging of the main capacitor.

摘要： A camera with a visual line position detection device is capable of shortening the time required for auto focus detection and capable of more accurate selection of the focus detection point. The camera includes a focus detection device to output the results of distance measurements at a plurality of points where focus detection is possible and to detect focus for one of these points. A liquid crystal display device displays on a screen specified symbols overlapping the subject image on the positions corresponding to each of the points. A microprocessor accepts the results of the distance measurements from the focus detection system and selects one of the points based on the photographer visual line position as the point for focus detection among all the points whose distances are measured and on which focus detection is possible, excluding the points with an infinite focus distance.
