The method includes by processing circuitry of the 3D sensor system, generating second image data based on the first image data, the second image data having a second resolution less than the first resolution; and by the processing circuitry of the imaging sensor, determining that the second image data indicates that an object is present in the environment. The method includes responsive to the determining, providing the first image data from the 3D sensor system to one or more processors configured to generate a three-dimensional image of the environment based on the first image data.

A 2D/3D conversion processing section converts 2D contents (television broadcast program) received by a television broadcast receiving section to contents for the right eye and contents for the left eye for 3D, and the contents for 3D obtained by conversion are subjected to 3D display on a display section. When switching is made from 2D display to 3D display, a central control section suppresses display of data-broadcast data regarding television video data. Consequently, even if video display of the television broadcast is switched from 2D to 3D, video of television broadcast can be displayed in 3D as effectively as possible.

A camera device includes a camera head that captures an observation image of a target site which is obtained by a surgical microscope, and a camera control unit that processes a signal of the observation video captured by the camera head. The camera head captures right and left observation images having a parallax from the surgical microscope to obtain a high-resolution observation video including right and left parallax videos for one screen, and the camera control unit cuts out the right parallax video and the left parallax video from the observation video including the right and left parallax videos to generate a high-resolution 3D video which is displayed on a monitor in 3D and with which stereoscopic observation can be performed.

An imaging device includes an imager that images a multi-view image in which plural sub-images from plural viewpoints are aligned, a display that displays images; and a Central Processing Unit (CPU). The CPU is configured to: generate a main reconstruction image for viewing display after photographing by a main image generation process from the sub-images of the multi-view image, and store the main reconstruction image; obtain image displacement degrees for the sub-images respectively, wherein each of the image displacement degrees indicates a displacement between a position of a predetermined part in a sub-image and a position of a part corresponding to a photographic object captured in the predetermined part in another sub-image; determine a clipping size of partial images clipped from a predetermined range of the sub-images included in the multi-view image; and cause the display to display the main reconstruction image in the viewing display after the photographing.

A display panel driving method for driving a LED module of an electronic device to emit light, the method includes steps: controlling to scan a left-eye image and a right-eye image when the electronic device works at a 3D mode (S401); controlling the LED module to turn off and does not emits light during a predetermined period less than a scanning time of the left-eye image or the right-eye image, after switching to scan the left-eye image and the right-eye image (S402); and controlling the LED module to turn on and emit light after the predetermined period has passed (S403). The present invention also provides a backlight control circuit and an electronic device, the present invention capable of controlling the backlight module to emit light via the same signal and do not cause the interference between different signals.

The present invention is compact and inexpensive, has good light efficiency, and enables a display image having a plurality of display distances to be displayed. A display emits projection light for displaying a display image at a predetermined position, and an image formation position adjusting mirror receives the projection light emitted from the display, performs conversion into a plurality of first projection light and second projection light that have different image formation distances by changing the image formation distance of the projection light that is at least part of the incident projection light, and reflects the first projection light and the second projection light to project the first projection light and the second projection light onto a first screen and a second screen.

An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. The directional backlight may be arranged to switch between at least a first wide angular luminance profile mode and a second narrow angular luminance profile mode. The directional backlight is arranged to illuminate an LCD with a bias electrode arranged to switch liquid crystal directors in black state pixels between a first wide angular contrast profile mode and a second narrow angular contrast profile mode. Performance of privacy operation for off-axis snoopers is enhanced in comparison to displays with only directional backlights or switchable contrast properties.
