Abstract: A method and system to facilitate identifying and recording capture location of recorded video. A computing system determines multiple locations where a first wireless communication module and second wireless communication module have lost wireless connectivity with each other, as possible locations where a video camera may be used to capture video. The computing system then outputs, for presentation to the videographer or another user, a location-selection prompt that specifies the multiple determined locations as candidate capture-locations for a video that was captured by the video camera. Further, the computing system receives, in response to the location-selection prompt, data that represents a user selection of one of the specified locations. The computing system then records the selected location as capture-location metadata for the video, such as capture-location data integrated with the video or in a database relationship with the video.

Abstract: For use in a teleconference system, a method of reducing line width variations, which are assumed to be the result of undersampling of the original image. Bilevel data received at a remote site is written into a pair of two-dimensional storage arrays. Data stored in the first array is examined row by row to identify different length-dependent classes of black horizontal pel runs. White or black pels in the second array are overwritten with gray pels at specific pel locations as a function of run length to reduce variations in length. The first array data is then examined on a column by column basis. Black vertical runs are classified and the second array is overwritten with gray pels using the same rules as were applied to horizontal runs. The trilevel second array data may be used to drive a display monitor or may first be subjected to further image processing.

Abstract: A technique for enhancing a displayed image originally stored at a density of 1 data bit per pel. The stored data is scanned to locate unit steps, one-row or one-column steps in binary values. Whenever a unit step is found, the distance from the step to the nearest transitions on both sides of the step are found. The distances are used to access lookup tables which assign 4 bit gray scale values to limited numbers of pels on both sides of the unit step. The assigned gray scale values produce a gradually-darkening string of pels extending through the step. When the entire image field has been scanned, a maximum 4 bit pel value is assigned to any unmodified pel having an original binary value of 1 and a minimum pel value is assigned to any unmodified pel having an original binary value of 0. The visual quality of the displayed image is enhanced by the selective introduction of intermediate gray scale values for pels adjacent unit steps.
