q Un-tethered ‘Continuous’ mode allows capture of image sequences for storage in memory and
subsequent download to PC.
q Piezo buzzer indicates a number of useful events to the user, e.g. whether enough light is present for
picture capture, etc.
q LED indicator .
q “Clear all” function clears camera.
q “Low Resolution” mode increases number of images which can be captured by reducing image
resolution.

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:
q TWAIN driver to suit all TWAIN compatible imaging applications
q Video for Microsoft Windows™ PC driver for tethered video mode (through USB), available at all
resolutions, with fastest framerates at QCIF resolution
q AVI video file creation from image sequences captured in ‘continuous’ mode
q 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:
q the OEM to write a custom application and upload sound memos based on the example LCDC demo
software.
q the OEM to write a custom application and download custom sounds to the camera based on the
example CustomSound software.
1.2.4 Power management features and USB compliance
q Retention of pictures, recorded sounds and downloaded custom sounds with extremely low power
operation. The camera seems to be “switched off”.
q Auto power-off after 30 seconds of non usage.
q Operates from 4.5-6V battery, although system voltage is 5V or 3.3V, dependant on sensor.
q Low battery detection.
