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 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.

摘要： A solid state image sensor drive apparatus in accordance with the present invention enables a solid state image sensor to start integration of photoelectric current in response to an integration clear signal so that electric charges are accumulated to a prescribed level and transferred to a shift register. The accumulated electric charges transferred to the shift register are read out successively based on a transfer signal so that it is supplied to a microcomputer performing various operations. At this time, if a request for interruption is inputted from a load to the microcomputer, the transfer signal supplied to the shift register is stopped and the content of the shift register is not supplied to the microcomputer. When the interruption processing in the microcomputer is completed, the transfer signal is supplied again to the shift register so that transfer of data from the shift register to the microcomputer is restarted.

摘要： A camera with an AF and AE control structure including a one-shot AF mode and a continuous AF mode, in which the operability and exposure control are improved. The camera includes a unit for detecting a focusing condition of an objective lens, defined by the relationship between a position of an object to be photographed against the lens and a focus point of the lens; a unit for focusing the lens in accordance with the detected focusing condition so that the lens is moved to the in-focus position, a first light measurement unit for measuring light at a spot area corresponding to a region of the object to be detected at the detecting unit, a second light measurement means for measuring averaged light at another area broader than the first area, and a unit for controlling exposure amount. The exposure control unit determines the exposure amount on the basis of the spot metering data in a one-shot AF mode, or the averaged light measuring data which is defined as a data at a time, at least, when the lens is adjacent to the in-focus position, in a continuous AF mode.

摘要： A focus condition detecting device which generated first and second light intensity distribution signals representing light intensity distributions on first and second arrays arranged to receive lights having passed through different areas of the exit pupil of an objective lens is arranged so as to divide the first light intensity distribution signal into a plurality of blocks. Each of the portions of the first light intensity distribution signal belonging to the respective blocks is shifted relative to the second light intensity distribution signal by sequentially changing an amount of shift, so that correlations therebetween are calculated for finding the amount of shift providing the highest correlation. In accordance with the amount of shift found to provide the highest correlation through the correlation calculation with use of the portion of the first light intensity distribution signal belonging to one of the blocks, the shift range for the succeeding correlation calculation with use of the portion of the first light intensity distribution signal belonging to another one of the blocks is restricted to shorten the period of time required for the succeeding correlation calculation.

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.
