Abstract

A camera of the present invention comprises a contrast detection section for detecting a contrast value, an assist light section for irradiating a subject by emitting light at a first luminance amount or a second luminance amount that is dimmer than the first luminance amount, and a control section for moving the photographing lens and detecting a focus position of the photographing lens based on contrast values detected by the contrast detection section, wherein the control section causes the assist light section to emit assist light in a first luminance amount or a second luminance amount, and detects a focus position of the photographing lens based on one of a first contrast value detected in a state where the assist light section emits light in the first luminance amount, or a second contrast value detected in a state where the assist light section emits light in the second luminance amount.
