Abstract
Abstract A video frame imaging system for processing image data, including video frame data, and for printing images corresponding to print image data, comprising a computer having a processor for receiving and processing video frame data and for generating print image data and having a computer port connector, an arbitration control circuit, and a grab printer. The grab printer includes an integrated video capture unit for creating video frame data from a video input, a printer unit for printing images corresponding to print image data, and a grab printer port connector. The computer port connector and the grab printer port connector are coupled together and responsive to the arbitration control circuit to transfer video frame data created by the video capture unit between the video capture unit and the computer for processing by the computer in a first mode of operation. The computer port connector and the grab printer port connector are responsive to the arbitration control circuit to transfer print image data between the computer and the printer unit for printing images using the printer unit in a second mode of operation.
