Abstract
Official abstract text for this publication.
A camera includes: a taking lens forming an image of a subject; an image pickup unit; a subject brightness acquisition unit acquiring the brightness information of the subject on the basis of the output of the image pickup unit; a control unit controlling the exposure according to the brightness information acquired by the subject brightness acquisition unit; and a storage unit storing the information indicating the optical state of the taking lens before the subject brightness acquisition unit acquires the brightness information. The control unit determines whether or not the brightness information is acquired again by the subject brightness acquisition unit according to the information about the optical state of the taking lens stored in the storage unit when the subject brightness acquisition unit previously acquired the brightness information, and the information about the optical state of the taking lens when the latest brightness information is acquired.
First claim
Opening claim text (preview).
What is claimed is: 1. A camera, comprising: a taking lens forming an image from light of a subject and including a diaphragm unit limiting luminous flux which passes through the taking lens; an image pickup unit converting the image formed by the taking lens into an electric signal; a subject brightness acquisition unit acquiring brightness information of the subject on the basis of output of the image pickup unit; a control unit controlling exposure according to the bright…
