A transmittance estimation unit 11 estimates a transmittance for each of regions from a captured image. The transmittance estimation unit 11 estimates the transmittance for each pixel, using, for example, dark channel processing. A transmittance detection unit 12 detects a transmittance of haze at the time of imaging of the captured image, using the transmittance estimated for each pixel by the transmittance estimation unit 11 and depth information for each pixel. The transmittance detection unit 12 detects the transmittance of the haze on the basis of, for example, a logarithm average value of the transmittances in the whole or a predetermined portion of the captured image, and an average value of depths indicated by the depth information. Alternatively, the transmittance detection unit 12 converts a grayscale of the transmittance estimated for each of the regions from the captured image into a grayscale of the depth indicated by the depth information for each of the regions and sets the transmittance after the grayscale conversion as the transmission of the haze. This enables the transmittance to be detected with high accuracy.
