ABSTRACT:
To provide an image pick-up apparatus, a fingerprint certification apparatus, and an image pick-up method capable of correcting a light volume unevenness by variation of the light volume in a plurality of light sources. An image pick-up device unit comprises pixels which are two dimensionally arranged, and images an object. A light source consists of a plurality of LEDs arranged in parallel to the main scan direction of the image pick-up device unit, and impinges a light on the object. A LED driving unit controls the luminance of a plurality of LEDs so that the light volume distribution of the center region of the main scan direction in the image pick-up device unit becomes more uniform.
