| description | Disclosed is an imaging apparatus provided with: a light irradiation unit which irradiates a target area with light; a differential image generation unit which generates a differential image between a first image which was taken in synchronization with the irradiation period during which the light irradiation unit irradiates the light and a second image which was taken outside the irradiation period; a transmittance estimation unit which estimates the light transmittance of an object in the target area; and a light exposure adjustment unit which adjusts the exposure based on the estimation result from the transmittance estimation unit. The transmittance estimation unit estimates the transmittance of the object from at least one of the first image, the second image, and the differential image. |
