ABSTRACT:
A digital camera has a half mirror that splits the optical path from a taking lens to the image-sensing device and an optical viewfinder that offers the light reflected from the half mirror as a visible image. Inside the optical viewfinder, a photometric device is disposed. The amount of light measured by the photometric device is used for exposure control in ambient-light shooting and for automatic light adjustment in flash shooting.
