1.2.3 User features on PC software
PC software allows a number of features such as fast download of thumbnail images for picture
selection, and automatic detection and correction of sensor defects. The driver compatibility
includes:
● TWAIN driver to suit all TWAIN compatible imaging applications
● Video for Microsoft Windows PC driver for tethered video mode (through USB), available at all
resolutions, with fastest framerates at QCIF resolution
● AVI video file creation from image sequences captured in ‘continuous’ mode
● Quicktime Video driver and Adobe Photoshop stills plug-in for Mac
Custom OEM PC software can be developed by using the SDK (for SDK availability, contact ST), to
upload thumbnails/still images or ‘continuous’ images, e.g. for AVI file creation.
The SDK (version 2.90 or later) allows:
● the OEM to write a custom application and upload sound memos based on the example LCDC demo
software.
● the OEM to write a custom application and download custom sounds to the camera based on the
example CustomSound software.

● Auto power-off after 30 seconds of non usage.
● Operates from 4.5-6V battery, although system voltage is 5V or 3.3V, dependant on sensor.
● Low battery detection.
