    摘要: At least one electro-optical light shielding member is disposed close to a reticle of a photographic camera arranged for forming an image of an object to be photographed. The light shielding member is electrically controlled to have the reticle partly light-shielded by the light shielding pattern of the light shielding member in such a manner as to permit selection between an averaging light measuring mode and a spot light measuring mode.

    摘要: There is disclosed a device for correcting the accumulation time of a photoelectric converter composed of self-scanning charge-accumulation elements of plural bits on the basis of the average intensity to the incident light to the converter. The charge accumulation time is controlled by determining a reference value according to the maximum value of the output signals obtained from the photoelectric converter and comparing this reference value with the average intensity.
