Abstract:
Devices and methods for reducing parallax in graphic content captured by a camera array include identifying color fringes that correspond to the parallax in the captured graphic content, determining an amount of displacement of the color fringes and adjusting the parallax in the captured graphic content based on the amount of displacement. The camera array may comprise a two-dimensional array of cameras.

Abstract:
The present invention intends to provide a small video camera apparatus capable of imaging an object from various angles, and effectively monitoring an object or obtaining three-dimensional image information. A light beam supplied from an optical image passing through a lens is picked up by a right image sensing surface of a charge-coupled device, and a light beam supplied from an optical image passing through a lens and a prism is picked up by a left image sensing surface of the charge-coupled device. The image signals obtained by the right and left image sensing surfaces are divided in a color separating and signal processing circuit.
Abstract:
An optical arrangement and a process for transmitting and converting X-ray images generated on a two-dimensional primary image array (21a) with light emission within the visible spectrum contains a plurality of optical systems (17) for reduced imaging of a sectional image (19) corresponding to an individual segment (19) of the primary image (20). The imaging is effected through an optical image guide (22). At least two image guides (22) are joined to combine sectional images into first images (19b). Each first image then contains at least two segments (19, 19a) of the primary image (20). The image guides (22) on the output side are connected to the input of a converter (28) by which the light signals are converted into processable electrical signals.
Abstract:
A video surveillance system has a camera equipped with a fisheye lens having a substantially hemispheric field of view. The system implements operations equivalent to the panning, tilting and zooming of a conventional camera without the use of moving parts. The lens is mounted vertically above a plane under surveillance. The camera produces a fisheye image made up of a plurality of pixels. The fisheye image is distorted due to the properties of the fisheye lens. The system corrects the distortion by mapping the pixels of the fisheye image to coordinates produced by selecting a particular part of the fisheye image to be viewed. This allows an operator to select parts of the field of view of the fisheye lens and view them as if they had been produced by a camera having a conventional lens being panned tilted or zoomed. The fisheye image formed by the camera is split into four separate image components carried by four bundles of optical fibers. Each bundle has a CCD and associated image processing circuitry which forms an electronic representation of the image component carried by that bundle.
Abstract:
A contact image sensor is provided with a modified photodevice module and method of operation. The photodevice modules convert the video signals created by the sensed lights from an electrical charge to electrical voltage immediately upon stimulation of the photodevice, and hold the electrical voltage at another element in the photodevice module so that the voltage can be immediately output when the shift register output switch is turned on. A dark current elimination circuit is also provided and includes a light-shielded photodevice which produces a dark current reference signal representative of the expected dark current in the photodevices of the photodevice modules. This dark current reference signal is used to adjust the electrical charge created by the light stimulation of the photodevice.
Abstract:
An electronic apparatus for converting an optical image of an object into a digital representation of this optical image is described. The apparatus comprises a cartridge having a first portion through which light emitted from a visible image of an object enters into the cartridge, which comprises a two-dimensional array of focusing elements, each of which having a field of vision intersecting a given area of the visible image. Adjacent ones of these focusing elements have fields of vision intersecting common portions of the visible image, whereby substantially the entirety of the visible image is covered by combined fields of vision of the focusing elements. The cartridge further comprises a two-dimensional array of optical sensors arrays, each of which being optically associated with a respective one of the focusing elements. These optical sensors arrays produce groups of analog pixel signals representing partial images associated with corresponding areas of the visible image. The apparatus further comprises a controller interface and a computer controller for .converting the groups of digital pixel signals into composite digital pixel signals associated with the respective points of a composite digital representation of the optical image.
Abstract:
An image processing device rearranges image signal output in a different order from a spatial order of photosensitive elements to be in the order of the photosensitive elements. A logical value output of a flip-flop is switched each time a line start signal is input. As a third selector switch is connected to the flip-flop, it is also switched following this behavior, by which region or lower half region of a whole memory region of a RAM for pixel data values is specified each time a pulse is output from a line start signal generator. While the image pixel data values for one line are being written in a half region of the whole memory region of the RAM, the pixel data values for the previous line are read from the other half region of the memory region in accordance with an order predetermined by counted value conversion circuitry.
Abstract:
The invention relates to an image display or shooting apparatus, in which several matrixes are joined edge to edge in accordance with the same plane, so as to form a large apparatus. The addressing circuits of the rows and columns of said matrixes are subdivided into addressing subcircuits and located in areas which are naturally inactive, or which are made deliberately inactive, i.e. areas having no active elements. In the case of shooting or photographing, in order to make the areas inactive, the active elements of certain pixels are destroyed in order to install in their place the addressing subcircuits, the information normally contained in the destroyed pixels being replaced by a reconstitution information obtained by averaging the information of adjacent intact pixels. The invention more particularly applies to the retinas of cameras used for the detection of non-focusable radiation and which are more particularly employed in radiology and nuclear imaging.
