An imaging system may be provided that includes a camera module, a transparent or translucent surface, and processing circuitry that is configured to perform character recognition operations based on images of the translucent surface that have been captured using the camera module. The camera module may include an image sensor having an array of image pixels and one or more lenses that focus light from the translucent surface onto the array of image pixels. The processing circuitry may be configured to recognize gestures from one or more users on the translucent surface. The processing circuitry may be configured to extract user input data from captured images of an object seen through the translucent surface by extracting gesture point locations from the captured images, storing coordinate data associated with the extracted gesture point locations, and comparing the stored coordinate data with template data that corresponds to a plurality of known characters. |
