Hardware: PC Capture

• The lower left lists various external devices that provide a video source for still image capture.
• Digitization completes the capture process, feeding large volumes of data onto the host computer bus, for processing (e.g., by Photoshop) and perhaps compression (e.g., using JPEG) prior to recording on a mass storage device.
• Playback can occur later, with the image transmitted to display RAM (that is often dual ported), processed or mixed with graphics or other sources, and displayed on a monitor.
