For Single Scanning Device Color Camera Patents (Class 348/260)
  • Patent number: 8723995
    Abstract: A digital color imager providing an extended luminance range, an improved color implementation and enabling a method for an easy transformation into another color space having luminance as a component has been achieved. Key of the invention is the addition of white pixels to red, green and blue pixels. These white pixels have either an extended dynamic rang as described by U.S. patent (U.S. Pat. No. 6,441,852 to Levine et al.) or have a larger size than the red, green, or blue pixels used. The output of said white pixels can be directly used for the luminance values Y of the destination color space. Therefore only the color values and have to be calculated from the RGB values, leading to an easier and faster calculation. As an example chosen by the inventor the conversion to YCbCr color space has been shown in detail.

  • Patent number: 8624985
    Abstract: A wide angle, athermalized, achromatic, hybrid imaging lens assembly captures return light from a target over a field of view, and projects the captured return light onto an array of image sensors of a solid-state imager during electro-optical reading of the target. The assembly includes a plastic lens group for optical aberration compensation, a glass lens group spaced away from the plastic lens group along an optical axis, and an aperture stop between the lens groups and having an aperture through which the optical axis extends. The glass lens group has substantially all the optical power of the imaging lens assembly for thermal stability, and the plastic lens group has substantially no optical power. A holder holds the lenses and the aperture stop in front of the array.

  • Patent number: 8619167
    Abstract: A method for displaying or capturing an image comprises directing an illumination beam onto a mirror of a highly resonant, mirror-mount system and applying a drive signal to a transducer to deflect the mirror. In this method, the drive signal has a pulse frequency approaching a resonance frequency of the mirror-mount system. The method further comprises reflecting the illumination beam off the mirror so that the illumination beam scans through an area where the image is to be displayed or captured, and, addressing each pixel of the image in synchronicity with the drive signal to display or capture the image.

  • Patent number: 8436909
    Abstract: In one embodiment, a light sensor includes four cell arrays, one for each color of the Bayer pattern, and four lenses each focusing the light coming from the scene to be captured on a respective cell array. The lenses are oriented such that at least a second green image, commonly provided by the fourth cell array, is both horizontally and vertically shifted (spaced) apart by half a pixel pitch from a first (reference) green image. In a second embodiment, the four lenses are oriented such that the red and blue images are respectively shifted (spaced) apart by half a pixel pitch from the first or reference green image, one horizontally and the other vertically, and the second green image is shifted (spaced) apart by half a pixel pitch from the reference green image both horizontally and vertically.

  • Patent number: 7978216
    Abstract: A conference adapter. In an illustrative embodiment, the conference adapter implements a method for interfacing one or more conference endpoints with one or more conference servers. The method includes registering an endpoint and a conference server to determine endpoint registration information associated with the endpoint and to determine conference-server registration information associated with the conference server. Next, the method includes receiving a connection from the endpoint and a connection from the conference server. Subsequently, the conference adapter establishes communications between the endpoint and the conference server as initiated by the endpoint and based on the endpoint registration information and the conference-server registration information.

  • Patent number: 7053943
    Abstract: A scanning circuit operates at a driving speed approximately twice the conventional speed when clock signals having the same frequency as those in the prior art are supplied. By alternately driving the switches in even-numbered and odd-numbered transfer stages T1 to Tn, the input side and the output side of each transfer stage are simultaneously made high in order of T1, T2, . . . and Tn. Logical AND circuits are connected to the even- and odd-numbered stages to output pulse signals for scanning at intervals shorter than the clock period.

  • Patent number: 6535300
    Abstract: A picture signal processing apparatus and method is presented that determines whether there is an odd or even-number field signal in the picture signals received, by referring to flags that are turned on or off in accordance with the result of odd and even-number field detection. If the odd and even-number field flags are on, an image processing operation A is performed. If the odd-number field flag is on and the even-number field is off, an image processing operation B is performed. If the odd-number field flag is off and the even-number field is on, an image processing operation C is performed. In accordance with whether there is an odd or even-number field signal in the received picture signals, an appropriate image processing operation is selected from the different operations. That is, the received picture signals are processed in a mode suitable to the signals, so as to generate suitable image data.
