Abstract: A stereoscopic camera and associated method for capturing a stereoscopic image pair are provided. As an example, a stereoscopic camera includes first and second lenses defining parallel optical axes. The stereoscopic camera also includes first and second image sensors for receiving optical signals from the first and second lenses. The first and second fields of view are defined so as to overlap to define a first area of coincidence when the first and second lenses are spaced apart by a first distance. The first and second lenses are configured to be repositioned to be spaced apart by a second distance with the first and second image sensors being correspondingly repositioned to alter a space therebetween such that the first and second fields of view overlap to define a second area of coincidence when the first and second lenses are spaced apart by the second distance.
Abstract: An original image layer is mixed with one or more graphics layers to form a composite video signal, such as in a vision mixer. Also, the same graphics layers are mixed identically into another, known background image layer to give a second composite video signal. The currently applied added graphics layers are determined, without directly accessing the added graphics layers themselves, using only the first and second composite video signals, the original image layer, and the known background image, such as in a graphics layer detection device. A triangulation matting algorithm may be used in one example.
Abstract: A super resolution bore imaging system is disclosed for imaging a cylindrical bore. The system includes a controller, a photodetector configuration having a known pixel geometry, and an imaging arrangement that images bore surface segments onto the photodetector. In one embodiment, the controller is configured to acquire respective combinable sets of raw bore segment image data using the pixels of the photodetector configuration positioned, relative to the bore segment, at respective imaging-Z coordinates which are separated along the bore axial direction by a subpixel shift. In some embodiments, the pixel geometry is configured to provide super resolution along the circumferential direction without a change in position along the circumferential direction between acquiring the respective sets of image data. The controller combines the sets of raw image data to form a super resolution image data for the bore segment.

Abstract: Certain aspects relate to systems and techniques for submicron alignment in wafer optics. One disclosed method of alignment between wafers to produce an integrated lens stack employs a beam splitter (that is, a 50% transparent mirror) that reflects the alignment mark of the top wafer when the microscope objective is focused on the alignment mark of the bottom wafer. Another disclosed method of alignment between wafers to produce an integrated lens stack implements complementary patterns that can produce a Moiré effect when misaligned in order to aid in visually determining proper alignment between the wafers. In some embodiments, the methods can be combined to increase precision.

Before performing the mix processing, a format of the first video data and the second video data is made the same as a video format handled by the mixing unit. Further, after performing the mix processing, a format of the output video data is made the same as an output video format.
