PHOTOSENSOR DEVICE FOR CONTROLLING EXPOSURE

Title:

PHOTOSENSOR DEVICE FOR CONTROLLING EXPOSURE

Document Type and Number:

Japanese Patent JPS61213734

Kind Code:

A

Abstract:

A photosensor arrangement for providing an exposure influencing control signal in a photographic camera apparatus includes an array of photoresponsive elements (P₁-P₄) each arranged to have a different field of view, signal-generating means (R₁₄-R₂₂) for generating the exposure-influencing signal in response to signals from the photoresponsive elements, and means (R₁-R₈; D₁-D₈; A,-As; 10-24) controlling the transmission of the output signals from the photoresponsive elements to the signal-generating means (R₁₄-R₂₂) and operative to block the signal path to the signal-generating means from the photoresponsive element or elements detecting the highest and/or lowest scene light intensity, or from any photoresponsive element which detects a scene light intensity which is above a maximum light intensity threshold and/or any photosensitive element which detects a scene light intensity which is below a minimum light intensity threshold.
