What you could use would depend on the nature of the images you need to
display.  If you can use text and graphics characters I suggest you
visit http://www.stv5730A.co.uk and have a look at the 16F84/628 on
screen display project board.

Features:
* 16F84 microcontroller for flexible development.
* STV5730A on screen display IC gives 28 characters by 11 row screen
* 128 text and graphics characters defined in ROM
* Text over video or self generated video signal
* 10 16F84 i/o lines allow easy interface to sensors, keypads, etc
* Power supply 5V dc or 9 - 12dc via on board regulator
* Free demo software
* Enclosures, accessories and connectors available

For general information the STV5730A is due to cease production in May
of next year and most distributors will not accept orders after November
of this year.

Kayode.
