If we were looking at a wish list for an ideal design it would include any or all of:
- SRAM or DRAM to hold the current image or even an image sequence
- Flash memory interface (USB or SD card) to hold lots of images
- USB interface for PC control, perhaps even for dynamic teletext
- Higher sample rate (13.5MHz), with oversampling probably computed at picture load time, to solve output filter problems
As it is, ImoGen fills a gap in the market and does it well.
