ABSTRACT:
An image shooting apparatus has a detector for acquiring information needed to control the focus of a taking lens in a plurality of target areas within the shooting area, and a light emitter having a plurality of light-emitting portions for illuminating the plurality of target areas. The light-emitting portion that is located farthest away from the taking lens illuminates the target area that is located opposite to that light-emitting portion with respect to the taking lens. Moreover, the light-emitting portion located farthest away from the taking lens and the other light-emitting portions use a common light source so that light from this common light source is divided and shone onto the plurality of target areas. Furthermore, the plurality of light-emittining portions are so arranged that the optical paths of the light beams emitted therefrom cross one another.
