  • Signal reshaping for high dynamic range signals
    Patent number: 11924477
    Abstract: In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and/or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.

  • CREATION AND PLACEMENT OF TWO-DIMENSIONAL BARCODE STAMPS ON PRINTED DOCUMENTS FOR STORING AUTHENTICATION INFORMATION
    Publication number: 20090238625
    Abstract: A document authenticating method is disclosed by which numerous small-sized two-dimensional barcode stamps are generated and placed in a distributed manner on a printed document. The small-sized barcode stamps collectively encode the content of the document to be used for document authentication. In one example, the stamp size is about ¼ by ¼ inches or less and the tile size for the stamps is 4 by 4 pixels at a resolution of 400 dpi. The document is segmented into segments each containing a paragraph or a line of text. For each segment, a set of barcode stamps encoding the authentication data for the segment is placed in the vicinity of the segment. They may be placed in the empty space in the last line of each paragraph, in the empty space between adjacent paragraphs, or at the beginning or end of each line.

  • Computer-readable storage medium, information processing apparatus, information processing system, and information processing method
    Patent number: 9278281
    Abstract: A marker present in a real space is detected from each of a real image for a left eye and a real image for a right eye. The position and the orientation of each of imaging sections relative to the marker are calculated. A left virtual camera and a right virtual camera are set in accordance with the positions and the orientations of the imaging sections. A virtual model having a planar shape is placed in a marker coordinate system, and areas in the real image for a left eye and the real image for a right eye that correspond to the virtual model are set as a left texture area and a right texture area, respectively. Each of images included in a left texture area and a right texture area is applied, as a texture, to a deformation object into which the virtual model is deformed.

  • Interconnected solder pads and the method of soldering
    Patent number: 4557411
    Abstract: A new soldering technique is being employed whereby solder is formed into pads, each pad connected to the next pad by a solder link. The pads are formed on center spacings equal to the spaces between assembly board terminals and heated to the melting point of the solder whereupon surface tension of the solder collapses the interconnecting pad links thereby leaving the terminals electrically isolated. The solder pad assembly is made by an etching process.

  • Method and program for driving information processing device
    Patent number: 9626889
    Abstract: A method for driving an information processing device which is adaptable to a wider variety of input methods is provided. The coordinates of an operating body at a starting point in the XYZ space and the coordinates of the operating body at an ending point in the XYZ space after a certain period of time are obtained, and the Z coordinate at the ending point and the movement distance on the X-Y plane in the certain period of time are calculated. Then, a signal is output only in the case where both the distance from an operating surface to the operating body in the vertical direction and the movement distance in the horizontal direction exceed the respective threshold values. In this manner, input operation can be performed by a three-dimensional motion, which includes movement of the operating body in the vertical direction as well as in the horizontal direction.
