6/44
Support for CIF resolution sensor - 352 x 288 pixels
Support for VGA resolution sensor - 640 x 480 pixels
80 picture storage capacity possible for CIF, with 64MB memory
26 picture storage capacity for VGA, with 64MBit memory
A greater number of images can be stored when ‘Low’ resolution mode is enabled (e.g. 80 QCIF
images with 16Mbit memory, 107 QVGA images with 64Mbit memory). See
Automatic anti-flicker exposure and gain control
Support for flashgun.

“Delete Last” function
An additional user interface function is available in STV0681 with either audio record or playback
hardware fitted. With these, the user can delete the last image or continuous clip to be captured, or
the last audio memo to be recorded. The standard “Clear all” (“CL”) function remains, whether or not
audio hardware is fitted.
Backward compatibility with STV0680B
STV0681 is electrically and functionally compatible with cameras designed for STV0680B, and uses
the same PC/Mac drivers, however the change of device pinout means that some PCB re-design
will be required.
Precise design guidelines are available from ST as a reference design (see
development kit (SDK) for PC is available from ST to interface to the camera and provide the basis
to develop a custom software application for stills and/or video. It includes colour processing
software.
