Abstract: A solid-state image pickup apparatus includes a timing signal generator for generating timing signals. Particular gates formed in each of photosensitive cells arranged in an image pickup section are driven independently or simultaneously in response to the timing signals. In an independent drive mode, outputs each having particular sensitivity are obtained from the different photosensitive regions of the individual cell by one time of exposure, covering a range of sensitivity as broad as one achievable with repeated photometry. This reduces the number of times of photometry for determining adequate exposure. In a simultaneous drive mode, outputs are produced in the usual manner. An exposure value calculator converts the resulting image signals to values having a predetermined format while an exposure parameter determining section determines exposure parameters if those values are adequate.

Abstract: A novel device for image-shooting both surfaces of documents at a high rate by an electronic device. The device has an upper transport system for allowing plural documents to descend/move by a pre-set number at a time towards the downstream and an image-shooting device for image-shooting the descending/moving document. Image-shooting can be done simultaneously on both sides or side by side, either during free movement or controlled movement by a transporting device.

Abstract: A front chassis and a rear chassis of an electronic camera are made of light transmissible resin. The electronic camera has a plurality of light-shielding elements to prevent unnecessary light (external ambient light and internally emitted light, for example) from entering optical systems such as taking lenses and light guides which guide light to an electronic flash control sensor. Further, the shielding elements prevent unnecessary light from entering photoelectric converters such as imaging devices and electronic flash control sensors. These light shielding elements enables the interior components of the camera to be visible therethrough, while ensuring that operational functions of the electronic camera are not adversely affected by entering unnecessary light.

The device has an upper transport system for allowing plural documents to descend/move by a pre-set number at a time towards the downstream and image-shooting means for image- shooting the descending/moving document. Image-shooting can be done simultaneously on both sides or side by side, either during free movement or controlled movement by tranporting means etc.
