| 20090158315 | METHOD FOR EMBEDDING FRAMES OF HIGH QUALITY IMAGE DATA IN A STREAMING VIDEO - A method for embedding frames of image data in a streaming video is disclosed, comprising the steps of receiving a plurality of frames of image data of a target object over a period of time; compressing the plurality of frames of image data; embedding the plurality of compressed frames of image data in a streaming video; initiating a control signal during the period of time to embed a particular frame of image data; selecting a frame of image data from the plurality of frames of image data received near the time the control signal is initiated; embedding a user data marker in the streaming video; and embedding the selected frame of image data in the streaming video as user data, wherein the embedded selected frame of image data has a higher quality than the embedded plurality of compressed frames of image data. | 06-18-2009 |
| 20110149413 | SYSTEM FOR PROVIDING TWO POSITION ZOOM-FOCUS - A system for providing a two-position zoom-focus capability in a video inspection device comprising, in one embodiment, a focus lens cell and primary aperture attached to a set of fixed rails and connected to a zoom lens cell. In one embodiment, the focus lens cell is moveable into a first position along the rails through activation of a proximally located lens movement mechanism, and moveable into a second position through relaxation of a tensioned focus spring. In one embodiment, movement of the focus lens cell between first and second focus positions causes movement of the zoom lens cell and a secondary aperture between corresponding first and second zoom and aperture positions to provide unmagnified and magnified images of a target object. | 06-23-2011 |
| 20110205552 | FRINGE PROJECTION SYSTEM FOR A PROBE WITH INTENSITY MODULATING ELEMENT SUITABLE FOR PHASE-SHIFT ANALYSIS - An intensity modulating element for a probe having a plurality of light emitters for phase-shift analysis and measurement is disclosed. The intensity modulating element comprises a plurality of columns of a plurality of grating elements formed by two opposing patterns. | 08-25-2011 |
| 20110210961 | METHOD OF DETERMINING THE PROFILE OF A SURFACE OF AN OBJECT - A method of determining the profile of a surface of an object is disclosed that does not require that the video inspection device be at a certain angle relative to the surface when an image of the surface is obtained (e.g., allows non-perpendicular captures of the image | 09-01-2011 |
| 20120014563 | METHOD OF STRUCTURED LIGHT-BASED MEASUREMENT - A method of determining the distance to an object can use a video inspection device comprising a first light emitter and a second light emitter, wherein the first light emitter can emit light through an opening with at least one shadow-forming element. The method can comprise capturing at least one first emitter image with the first light emitter activated and the second light emitter deactivated, capturing at least one second emitter image with the second light emitter activated and the first light emitter deactivated, determining a first plurality of luminance values of the pixels in the at least one first emitter image, determining a second plurality of luminance values of the pixels in the at least one second emitter image, determining the brightness ratios of the second plurality of luminance values to the first plurality of luminance values, and determining an object distance using the brightness ratios. | 01-19-2012 |
