摘要： A distance measuring apparatus of the present invention converges the reflected light on objects through a converging lens and detects the light by a multi-divisional photodiode. The multi-divisional photodiode comprises a plural number of light receiving elements so that each of the light receiving elements detects the reflected light from the corresponding object to provide an electric signal according to the quantity of reflected light. The quantity of light in the peripheral portions of the flash or the converging lens is inherently smaller than the quantity of light in the central portion thereof. This distance measuring apparatus is improved so that a constant electric signal is obtained by any of the light receiving elements as far as the distance to the objects is constant. For example, such improvement is made in a manner in which: the quantity of received light of the central portion is limited by a filter provided between the converging lens and the multi-divisional photodiode; the light receiving areas of the light receiving elements are increased in peripheral portions of the multi-divisional photodiode compared with those in the central portion thereof; or the obtained electric signal is electrically corrected.

摘要： In an electronic camera having a photographic objective lens, a blocking member is disposed in the path of a propagation of a bundle of light rays from an object. The blocking member is adapted to prevent the bundle of rays from impinging on an image pickup device except during a photographic operation. The blocking member is retractable from the path to permit the bundle of rays to be incident on the image pickup device. A photoelectric conversion circuit includes photoelectric conversion elements arranged in the form of a matrix. A charge control circuit controls the amount of charges to be stored in the photoelectric conversion circuit while the blocking member is completely retracted from the path. An image processing circuit produces an image signal based on the amount of stored charges.
