Patent ID: 8294711

Claim:
A three-dimensional imaging device comprising: two or more imaging units for obtaining two or more images having a parallax therebetween by imaging a subject from different positions, the two or more imaging units having an optical zoom function; a three-dimensional processing unit for applying three-dimensional processing for three-dimensional display to the two or more images; a display unit for carrying out various types of display including three-dimensional display of the two or more images; and a display control unit for carrying out three-dimensional display by reducing the parallax between the two or more images while the imaging units carry out a zoom operation, wherein in a case where an object, which is displayed on the display unit other than the images obtained through imaging of the subject, is three-dimensionally displayed with being superposed on the three-dimensionally displayed image, the display control unit carries out three-dimensional display by reducing the parallax while the imaging units carry out the zoom operation, and wherein when the parallax is reduced, the parallax is reduced by ramping down from a first parallax to a second, smaller, non-zero parallax when the zooming operation begins, the parallax is maintained at the second, smaller, non-zero parallax during the zoom operation, and the parallax is increased by ramping up from the second, smaller parallax to the first parallax when the zoom operation is completed.
