Overview

Applications with the tri-mode camera based on STV0674 range from low-cost cameras containing

an icon LCD status display, microphone/speaker and small SDRAM chip (for example 16Mbit), to an

enhanced feature set camera containing a graphical image LCD display for image review, flashgun,

audio record/playback, NAND flash on the PCB and a SmartMedia flash memory socket.
