Abstract
A light-emitting element is arranged in a camera body to emit light toward part of the face of a user. A light-receiving element receives light reflected by the face. A detection unit detects shaking of the camera body on the basis of a change in photocurrent from the light-receiving element. The light-emitting element and the light-receiving element may be arranged as an eyeball detection unit for detecting the position of the eyeball of the user.
