A Compact Binocular 3D Camera-Recorder
A compact binocular three-dimensional (3D) camera-recorder has been developed. To produce good 3D pictures, it is necessary to minimize disparities between left and right eye pictures, such as vertical placement disparity and size disparity, which can lead to eyestrain and fatigue. In this camera-recorder, disparities in vertical placement are solved by factory adjustment, matching the effective image center with the optical axis of the lens even as the zoom position is changed. Disparities in size are eliminated through an automatic compensating system based on the zoom characteristic of the entire image capture unit—the lens, the prism, and the image sensors. Moreover, a new convergence angle control system adjusting a small lens in the image capture unit avoids the need for a heavy mechanism. As a result, easy operation, 2.4 kg weight, and 17 W power consumption have been achieved. Therefore, this 3D camera-recorder provides greater mobility and enables 3D video shooting in a wider variety of applications.
