    Abstract: A method for receiving user inputs in a system comprising a projector and a camera is provided. The method is based on determining an object's height above a reference surface. A surface map is used for mapping a location on the reference surface and a corresponding location in a camera-captured image having a view of the reference surface. In particular, a camera-observed shadow length, i.e. a length of the object's shadow observable by the camera, estimated by using the surface map, is used to compute the object's height above the reference surface (a Z coordinate). Whether or not the object touches the reference surface is also obtainable. After an XY coordinate is estimated, a 3D coordinate of the object is obtained. By computing a time sequence of 3D coordinates, the motional information, such as velocity and acceleration, is obtainable.

  • Patent number: 9007658
    Abstract: Color shift detection requires additional processing as compared to detection of other items, and thus increases the load on the inspection processing. Conventional inspection apparatuses have a problem that the processing speed associated with inspection is affected and the costs of the inspection processing apparatus are raised. In a case where an inspection setting specified by a user includes color shift detection (YES in S406), scan image data of a printed material for a test print is determined to be a reference (S407). Then, comparison is made between scan image data obtained by scanning the printed material associated with a print job and the scan image data of the printed material for the test print.
