240fps Single Lens 3D Video Recording
As Sony explains (in a fairly techy language), “in existing half mirror 3D camera systems with separate lenses for the left and right eyes, the parallax range is adjustable, enabling the depth of the 3D images to be modified. However, when operating the zoom and focus functions of such systems, the sensitivity of the human eye, in particular to differences in the size and rotational movement of dual images, as well as any vertical misalignment or difference in image quality has meant that complex technology has been required to ensure that each camera lens is closely coordinated, and there are no discrepancies in the optical axis, image size, and focus.” The separated left and right images are then processed and recorded with the respective left and right image sensors. As there is no difference in time between when the left and right eye images are captured, it is possible for natural and smooth 3D images to be captured, even of scenes involving rapid movement with the 240fps recording system, the new single lens optical system captures left and right images simultaneously to deliver natural and smooth 3D images with no accommodation-vergence conflict, but also eliminates the need for lens synchronization, ensuring easily accurate control of 3D zoom and focus functions. Plus, when polarized glasses are not used, viewers with still be able to see natural 2D images, as the disparity of the images for left and right eyes are within the range that human eyes can recognize as a blur.
