Abstract
A photometric apparatus includes a photosensor portion that receives light and performs a measuring operation for acquiring predetermined photometric data relating to the received light, a tilt sensor portion that detects a tilt angle with respect to a predetermined reference plane, and a measurement control portion that determines a tilt state of the photosensor portion based upon the tilt angle, and executes a measurement control process for specifying the photometric data acquired by the photosensor portion as effective photometric data, when the tilt state satisfies a predetermined condition.
