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： An annunciating apparatus for use with an electronic flash system includes a flash system which employs a trigger device generating a trigger signal at a time of test light emission and a light producing device responsive to the trigger signal for initiating operation of the light producing device to produce light. The annunciating apparatus includes a light sensitive device arranged to receive light passed through a photographic taking lens and produces a first electrical signal corresponding to an amount of light from a scene. The annunciating apparatus also includes a signal generating device for producing a second electrical signal corresponding to an aperture value preset on a camera at the time of test light emission for the electronic flash system and a comparison device for receiving the first and second signals to produce a control signal when the first electrical signal reaches a predetermined level. Finally, an annunciator responsive to the control signal annunciates whether a correct exposure obtains.

摘要： An image forming apparatus has image forming portions for forming images of different colors based on image information, a transferring portion for transferring images formed by the image forming portions sequentially in a superimposing manner, an image discriminator for automatically discriminating whether the image information is monochrome or multicolor, an image discriminating operation selector for selecting whether the image discriminator is to be operated, and a mode selector for selecting between a monochrome mode and a multicolor mode when the image discriminating operation selector is not selected. When the image discriminator is selected, the image forming speed in the monochrome and multicolor image formations is set to a first speed, irrespective of the result of the image discriminator. When the monochrome image forming mode is selected, the image forming speed in the monochrome image formation is set to a second speed higher than the first speed.
