Abstract
An apparatus and method of automatically digitizing analog video and stroke and with size and positioning information. This is accomplished using signal characteristics of the deflection waveforms and video signals together with the video synchronization and blanking timing. This allows analog real time positioning and scaling by synchronizing the video data and deflection information. The deflection information in the form of signals either or both horizontal or X axis and vertical or Y axis characteristics such as amplitude, peak or peak to peak, and zero crossing, can be used to determine the size or scaling for each axis independently.
Claims21
A method of automatically adjusting a position of a raster video image based on an analog deflection signal, the method comprising the steps of:
- a) digitizing the analog deflection signal and the raster video image;
- b) detecting a reference point in at least one direction from the digitized deflection signal;
- c) determining an offset of the digitized image from the reference point;
- and
- d) digitally adjusting a position of the digitized image based on the determined offset utilizing predetermined display functions.
A method of automatically adjusting a scale of an analog deflection based raster image, the method comprising the steps of:
- a) digitizing the raster image;
- b) determining at least one dimension of the digitized image utilizing image properties within a predetermined range;
- and
- c) scaling the digitized image in size and aspect ratio within the predetermined range of the digitized image.
