20080231710 | METHOD AND APPARATUS FOR CAMERA CALIBRATION, AND VEHICLE - A camera calibration apparatus has a parameter deriver adapted to find parameters for projecting images shot with N cameras (where N is an integer of 3 or more) onto a predetermined surface and merging the images together. The N cameras comprise a first camera, a second camera, . . . and an N-th camera. The i-th camera (where i is every integer between 1 and N, inclusive) shares a common shooting area with at least one of the other (N−1) cameras, so that there are a plurality of such common shooting areas in total. The parameter deriver finds the parameters based on the results of the shooting of the calibration patterns arranged in the common shooting areas with the corresponding cameras. The calibration patterns are arranged separate from one another. | 09-25-2008 |

20090067153 | BACKLIGHTED KEYBOARD AND METHOD USING PATTERNED LIGHT GUIDE - A keyboard apparatus. The apparatus has a housing including a plurality of key pads, including at least twenty six key pads spatially disposed within the housing. Each of the key pads is depressible upon touch by a user. An optically transparent circuit board is coupled to a backside of each of the key pads. The apparatus has a light guide characterized by a planar optically transparent material having a surface region, a width, a length, and a backside region, and a thickness provided between the surface region and the backside region. The apparatus has a plurality of patterns disposed on the surface region and optically coupled respectively to each of the twenty six key members. In a specific embodiment, the apparatus has a light emitting diode provided within a center region of the surface region to emit electromagnetic radiation. The electromagnetic radiation propagates from the light emitting diode through a portion of the thickness of the light guide to one or more of the plurality of patterns to direct one or more portions of the electromagnetic radiation to respective key pads for lighting the respective key pads. | 03-12-2009 |

20110181714 | CONGESTION DEGREE MEASURING APPARATUS - A congestion degree measuring apparatus includes a reproducer. A reproducer reproduces a reference image representing a state in which a plane is overlooked. A taker repeatedly takes a scene image outputted from a camera having an imaging surface that captures the plane. An allocator allocates one or at least two second areas respectively corresponding to one or at least two first areas designated on the reference image reproduced by the reproducer to the scene image taken by the taker. A measurer executes a process of measuring a congestion degree of one or at least two dynamic objects existing on the plane at each second area allocated by the allocator, based on the scene image taken by the taker. | 07-28-2011 |
20110181733 | CALIBRATING APPARATUS - A calibrating apparatus includes a first reproducer which reproduces a reference image representing a state in which a plane is overlooked, along an X axis and a Y axis orthogonal to each other. A second reproducer reproduces a scene image outputted from a camera that captures the plane, along a U axis and a V axis orthogonal to each other. An acceptor accepts a designating manipulation of designating a first area of an X-Y coordinate system, in association with a reproducing process of the first reproducer. A first calculator calculates a second area of a U-V coordinate system corresponding to the first area designated by the designating manipulation, by referring to a calibration parameter indicating a corresponding relationship between the X-Y coordinate system and the U-V coordinate system. A definer defines the second area calculated by the first calculator, in association with a reproducing process of the second reproducer. | 07-28-2011 |
20110181734 | CALIBRATION PARAMETER CREATING APPARATUS - A calibration parameter creating apparatus includes a first reproducer. A first reproducer reproduces a reference image representing a state in which a plane is overlooked, along an X axis and a Y axis orthogonal to each other. A first acceptor accepts a first designating manipulation designating a plurality of X-Y coordinates on the reference image reproduced by the first reproducer. A determiner determines whether or not a designated manner by the first designating manipulation matches an error condition, based on the plurality of X-Y coordinates designated by the first designating manipulation. A first generator generates a notification when a determined result of the determiner is positive. A calculator calculates a calibration parameter indicating a corresponding relationship between an X-Y coordinate system and a U-V coordinate system based on the X-Y coordinates designated by the first designating manipulation, when the determined result of the determiner is negative. | 07-28-2011 |
