Rochester, NY – February 7, 2005 – Imaging Solutions Group (ISG) has added advanced high-quality digital pan and zoom to their color and monochrome megapixel cameras. The ISG high-quality digital pan and zoom processor allows computer-controlled, pixel-accurate ROI panning and multi-tap filter-based digital zoom.
All camera controls are done via the 1394 interface, which includes the fully-programmable ISG image processing pipeline and dynamic range/gamma control LUT for any desired response curve. An on-board image buffer is also featured in these cameras, as well as a wide range of triggering and strobe control capabilities. These cameras come packaged with driver software and a user’s manual.
All area cameras from ISG will incorporate this digital pan and zoom algorithm inside the on-board FPGA. All ISG cameras have a fully implemented image path inside the camera and this new feature has been added to this image path.
“The advanced high-quality digital pan and zoom function was originally designed for defense surveillance and security applications, and now industrial customers are finding it most useful, especially in alignment applications,” said Kerry Van Iseghem, co-founder of ISG.
The digital pan function operates in real time and offers very smooth panning across the image sensor active region at the full frame rate at which the window is operating.
The scaling (zoom) function is an advanced scaling algorithm that allows for up to 10X magnification digitally through advanced interpolation of pixels. The results are very refined and smooth. Image quality is maintained throughout the zoom range with little to no pixelation artifacts.
The ISG digital pan and zoom algorithms can operate on any region of interest within the active region of the sensor, and all controls are handled through software by the host computer. All algorithms are contained within the on-board FPGA inside the camera.
ISG has seen wide usage of this feature in security and surveillance applications. Biometrics and facial recognition applications are expected to make use of these new features. Printed circuit board equipment vendors are using these features to improve fiducial alignment.
