PsF Imaging

PsF Imaging
HD
Progressive-Segmented Frame Imaging. All lines (whole frame) are captured at the same instant. Each frame represents a single moment in time. After the frame is captured, it is then separated (Segmented) into two halves. One half is the odd lines and the other is the even lines. (Now this may sound like interlace, but each frame represents only one moment in time, not two). Though transmitted similarly as an interlaced signal, if treated as a progressive signal, does not cause the same harmful artifacts that interlace scanning causes. Often image can be processed with much of the same transmission hardware that was designed for interlace. Processing hardware can also be designed to handle both Interlace and PsF (ie Switchable).
