What is STELLAR ™ ?
Advanced Low-Light Technology for Noise Reduction and Enhanced Color Imaging in Near Complete Darkness.
STELLAR™ technology is “Spatio Temporal Low Light Architecture” which allows for color imaging in near complete darkness. Arecont Vision® STELLAR™ technology utilizes a patented algorithm that reduces noise, motion blur, bit rate, and storage requirements. STELLAR™ has superior low light sensitivity, making it capable of covering areas where very little light is present.
STELLAR™ features a unique sensor specifically designed for low-light performance, enhanced color accuracy, and low noise level performance requirements. Utilizing cutting-edge technologies to enhance contrast and reduce motion blur and noise, cameras that feature the STELLAR™ technology generate high-quality color video under the most challenging lighting conditions – including near complete darkness.
STELLAR™ was developed using a custom designed lens and IR cut filter combination. Together, the lens and IR cut filter were optimized using a pass-band filter so that a particular range of wavelengths could be provided for the best color reproduction in low-light applications. Since STELLAR™ cameras deliver usable video with minimal ambient light in both color (0.02 lux) and monochrome (0.002 lux) modes, clear images are delivered even in the most challenging low light conditions. As a result, STELLAR™ is a balancing act between low-light performance and color accuracy.
STELLAR™ unique video processing algorithms are used to minimize noise and improve color accuracy, sharpness, brightness and contrast without sacrificing image resolution. These algorithms extract and analyze key image quality metrics, and use them to control lens, image sensor, and processor parameters to further enhance images in future frames.
Motion Blur Reduction
The STELLAR ™ algorithm is computationally inexpensive and operates using low memory and bandwidth with no artifacts. Motion blur and noise are minimized through custom algorithms using both the temporal and spatial data. STELLAR™ video processing algorithms were implemented in an efficient manner to best manage and control the camera's hardware resources and to not compromise or distort fast moving objects.
Arecont Vision® STELLAR ™ technology overcomes challenging lighting conditions by using a judicious selection of optical parameters to balance light collection, depth of field, and field of view throughout the design process. Fast-moving objects, such as traffic and gaming, can be captured without blur.
Bitrate and Storage Reduction
STELLAR™ simultaneously reduces bitrate and storage requirements by suppressing noise through temporal noise reduction. High-quality videos can be compressed more effectively, which in turn results in a lower bitrate. In addition, advanced video processing algorithms are deployed to improve quality before the video is compressed ensuring low-light videos do not consume excessive network bandwidth, or significantly compromise image quality while encoding noisy video. This groundbreaking feature further enhances the value of Arecont Vision® industry-leading megapixel imaging solution.
