A highlight suppression image pickup apparatus optically and electronically removes a highlight portion of an image before light reaches an imaging element, thereby obtaining a high-quality image. There are included a camera part ( 10 ) for acquiring a desired image; a highlight suppression signal producing part ( 22 ) for producing a non-binary highlight suppression signal on the basis of a blue channel image output among red, green and blue channel image outputs from the camera part ( 10 ); an active filter part ( 16 ) disposed in the vicinity of the focal plane of the camera part ( 10 ) for optically controlling, in accordance with the highlight suppression signal, the amount of light transmitted to a red and green imaging element part ( 15 ); a blue channel matching part ( 23 ) for electronically suppressing, on the basis of the highlight suppression signal, the blue channel image output; a restore signal producing part ( 24 ) for producing, on the basis of the highlight suppression signal, a restore signal; and a final image signal outputting part ( 28 ) for outputting the red, green and blue channel image signals obtained by the camera part ( 10 ) as an optically and electronically highlight-suppressed image.
