TVB Tech Alert: Sony’s Single Lens 3D Technology
Sony today announced the development of a single-lens 3D camera technology that the manufacturer says is capable of recording “natural and smooth 3D images of even
fast-moving subject matter such as sports, at 240 frames per second.” The
technology comprises a new optical system that captures left and right images
simultaneously, with existing high frame-rate recording technology to realize
240 fps 3D filming.
From Sony’s release on its new 3D development: “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” [is such] 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 single-lens system is said to solve such issues.
“Furthermore, by using mirrors in place of shutters, incoming light can now be
simultaneously separated into left and right images and recorded as it reaches
the parallel light area... 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.”
Sony said it plans to demo a prototype single-lens 3D model at CEATAC Japan
2009 in Chiba Oct. 6.
