ABSTRACT:
An image pickup device includes an image pickup section that picks up a long-time exposure image and short-time exposure image; a combining section that combines the long-time exposure image and short-time exposure image with each other, to generate a combined image, the exposure images being combined on the basis of a ratio between the exposure time of the long-time exposure image and the exposure time of the short-time exposure image; a dynamic range calculating section that calculates an object dynamic range from the long-time exposure image, the exposure time of the long-time exposure image, the short-time exposure image, and the exposure time of the short-time exposure image; and a compressing section that, using base compression curve data, calculates a compression curve suitable for the object dynamic range, and generates a compressed image in accordance with the calculated compression curve.
