  • Publication number: 20240040220
    Abstract: A camera has one or more rows of imaging lenses and an imaging sensor to capture a plurality of images formed by the imaging lenses. Each pair of the imaging lenses in a row is separated by an inter-lens spacing and the inter-lens spacing of any one pair of the imaging lenses is different from the inter-lens spacing of another pair. An image selection device is used to select the images formed by two imaging lenses for making a three-dimensional image. The number of the imaging lenses is three or more.

  • Patent number: 11190754
    Abstract: A display device has a display panel for displaying a composite image to allow a viewer to see a 3D image. The composite image has a plurality of right and left image strips alternately arranged. The display device also has camera to monitor a viewing position of a viewer. The camera has a camera lens and a sensor with a plurality of right sensor zones and left sensor zones to capture the viewer's right eye and left eye images. When the viewer is at a viewing position that the 3D image viewed by the viewer appears pseudostereoscopic, the viewer's right eye image is in one of the left sensor zones and left eye image is in one of the right sensor zones. A processor changes the order of the right and left image strips so that the viewer can see a orthostereoscopic image at that viewing position.

  • Patent number: 11032531
    Abstract: A mobile device has at least two camera lenses for taking a first image and a second image for forming a 3D image and a processor for composing a composite image from first image strips compressed from the first image and second image strips compressed from the second image in an interlaced manner. The composite image is conveyed to a display panel so that a viewer can see a 3D image through a parallax sheet with parallax separating units. The 3D image can be displayed with different magnification factors. When four lenses are used for taking a first pair of images and a second pair of images, the first pair is used for composing the composite image and the 3D image is viewed through a lenslet sheet.

  • Patent number: 11025886
    Abstract: A multiple-lens camera has only one image sensor to capture a number of images at different viewing angles. Using a single image sensor, instead of a number of separate image sensors, to capture multiple images simultaneously, one can avoid the calibration process to calibrate the different image sensors to make sure that color balance and the gain are the same for all the image sensors used. The camera has a processor to receive from the image sensor electronic signals indicative of image data of the captured of images. The camera has a connector to transfer the processed image data to an external device or to an image display. The image display device is configured to display one of said plurality of images.

  • Patent number: 10795176
    Abstract: A mobile device has at least two camera lenses for taking a first image and a second image as a stereo-image pair. The mobile device also has an electronic processor for composing a composite image from first image strips compressed from the first image and second image strips compressed from the second image in an interlaced manner. The composite image is conveyed to a display panel so that a viewer can see a 3D image through a parallax separating sheet with parallax separating units. The composite image can also be electronically shifted by haft an image strip to accommodate a viewer with a dominant eye. The shifting can be initiated by a viewer using a switch on the mobile device.

  • Patent number: 9086574
    Abstract: A compressed print having one or more compressed images of a symbol is disclosed. The compressed images are formed on an image forming surface under a lenticular sheet. The lenticular sheet has a plurality of lenticules and each of the compressed images has a plurality of image elements formed under a lenticule. Each of the image elements is corresponding to a different portion of the symbol. The lenticules are designed to be so small that the compressed image formed under each of the lenticules is not discernible when a viewer looks at the compressed print at a normal viewing distance. As such, the miniaturized compressed images of the symbol can be used as an identification tag, hidden in the compressed print.

  • Patent number: 8848040
    Abstract: A 3D display system uses a lenticular screen or a parallax barrier, along with a shutter plate, as a light directing device to allow a viewer's right eye to see a right image and the left eye to see a left image on a display panel. The right and left images are alternately displayed. The shutter plate has a plurality of right shutter segments and a plurality of left shutter segments arranged in an interleaving manner. When the right image is displayed, the right shutter segments are open and the left shutter segments are closed. When the left image is displayed, the right shutter segments are closed and the left shutter segments are open. But when the 3D display panel is used as a 2D display panel, both the right and left shutter segments are all open so that both the viewer's eyes see the image simultaneously.

  • Patent number: 8818185
    Abstract: A 3D photographic printer uses a monochrome panel for displaying two or more images for composing a 3D photograph. Each image has a plurality of color image components. A light source with selectable color light components is used to illuminate the monochrome panel corresponding to the displayed color image components. The images are displayed at different locations so that these images can be projected onto a 3D print material through a projection lens at different projection angles. With the digital display device, it is possible to electronically locate the images at different locations and shift the images or mechanically moving the display device during the 3D photographic composing process. It is also possible that only the print material is mechanically shifted to different locations. The display device and the projection lens can be stationary.

  • Patent number: 8629945
    Abstract: A viewing system has a parallax separation device placed in front of a liquid crystal display panel. The liquid display panel can be used to display a composite image that has many display segments, with each segment having two or more elongated image sections of different images. Each image section may occupy one or more columns of color pixels. The parallax separation device has a plurality of parallax separation elements, each aligned with a display segment for separating the different image sections as seen in a viewer's eyes. The parallax separation device has a barrier axis parallel to the longitudinal axis of the elongated image sections. The color sub-pixels in each pixel are arranged along a direction parallel to the barrier axis. A tracking device and a processor are used to determine the locations of image sections under the parallax separation elements based on positions of a viewer.
