Large or medium format camera with inbuilt automatic setting - accommodates all measurement, setting, image conversion, and parameter display components within camera

摘要

The construction for large and medium format cameras has a two-piece bellows-connected cassette frame (6,20) housing components for comprehensive measurement/display of relevant photographic parameters and an electronic image converter for the external video presentation of a field appearing on the focusing screen (4). Having set the screen in the image plane, the required settings of the system for the measurement of light value by a charge coupled device (ccd) and for the converter (12) optics is automatically achieved by the programmed interval electric drives without adjustment of the support (16,18). USE/ADVANTAGE -Enables important points of focusing screen image to be measured in terms of colour temperature with automatic light proofing of interior driving measurement. Automatically positions light sensor accurately in image plane and indicates depth of focus on screen. Accurate exposure.
