摘要： A camera with a multi-zone focus detecting device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a focusing condition is detected based on the image formed by the objective lens so as to produce a plurality of focusing condition data. Based on the result of the focusing conditions, one zone is selected. Furthermore, a light which has passed through the objective lens is measured separately in each zone so as to produce a plurality of measured light data. Based on a focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition. When the objective lens is driven to the infocus condition, a measured light data obtained from the selected zone is used for calculating exposure data with which the exposure is controlled.

摘要： A camera system with an auto-focusing system includes a camera body and an interchangeable zoom lens. The interchangeable objective lens stores various data to be sent to the camera body for improving automatic focus adjustment, such as an information necessary to convert the detected defocus information into a movement of the driving power source to carry out the automatic focus adjustment. The driving power source in the camera body is controlled in responses to the data from the interchangeable objective lens and the detected focus information, the driving power being transmitted to the interchangeable objective lens. The camera body is further capable of inhibiting the focus adjustment or focus indication in response to a data from the interchangeable objective lens under an unfavorable condition.

摘要： An image sensor system for sensing an image of an object includes a plurality of image sensor arrays. Each array comprises photoelectric converting elements arranged to receive the object image and accumulation cells coupled to each photoelectric converting element for accumulating charges produced from the photoelectric converting element. A buffer memory cells are coupled respectively to the accumulation cells for temporarily storing the accumulated charges shifted from the accumulation cells in response to the completion of the charge accumulation in each array. A shift register is provided to receive accumulated charges from the buffer memory cells in every one of the arrays after all the arrays complete the charge accumulation. The accumulated charges stored in the shift register are then sequentially outputted.

摘要： A camera system operable with data carried from a camera accessory to a camera body. The camera accessory has a ROM for storing various data at a plurality of addresses, respectively, each of which data consists of a plurality of bits, and a coupling terminal for receiving a train of clock pulses from the camera body. A circuit is also provided for sequentially designating the address of the ROM one by one to permit by ROM to output a data stored at the designated address. In the circuit, an address signal is formed in response to the clock pulses, received through the coupling terminal, for designating an address. The data derived from the ROM are transmitted to the camera body.

摘要： A camera is adapted to operate with stored data by sensing the film speed data prepared on the surface of a film cartridge loaded in the camera to produce a data reading signal and reading the sensed film speed data in response to the data reading signal and detecting whether or not the the film loaded in the camera includes film speed data to provide a warning when a determination is made that the film speed data is not on the film cartridge. Film speed data may be loaded in the camera manually and the warning is interrupted in response to the manual setting of the film speed. At least one of the film speed data and the manually set film speed data is stored and the exposure data is calculated on the basis of the stored film speed data.

摘要： A focus detection device which repeatedly calculates correlations between first and second image signals representing light intensity distributions on first and second image sensor arrays by shifting one of the image signals relative to the other to find an amount of shift affording the highest correlation includes shift range restriction means for restricting the shift range for the present correlation calculation in accordance with the amount of shift found through the last correlation calculation to afford the highest correlation. The shift range restriction is inhibited when the result of the last correlation calculation was not reliable indicating an infeasible condition of the focus detection.
