Abstract: An image capture device includes: first and second shooting sections, each of which is configured to shoot an image of a subject; a disparity calculating section configured to generate a depth map based on first and second images that have been shot by the first and second shooting sections, respectively; and an image generating section configured to generate, based on the depth map and the first image, a third image that has as high a resolution as the first image and that forms part of a 3D image. The image generating section is controlled to determine whether or not to generate the third image based on at least one of the states of the first and second images, a zoom power during shooting, and the tilt of the image capture device during shooting.

Abstract: An image capture device includes: first and second shooting sections, each of which is configured to shoot an image of a subject; and a signal processing section configured to generate, based on first and second images that have been shot by the first and second shooting sections, respectively, information indicating the amount of parallax between the first and second images. Based on at least one of the states of the first and second images, a zoom power during shooting, and the tilt of the image capture device during shooting, the signal processing section generates control information indicating the degree of stereoscopic property of a 3D image to be generated based on the first and second images or indicating whether or not the 3D image needs to be output, and records the control information and the information indicating the amount of parallax.
