Nethra Imaging Intros 3.2-MP Image Processor with JPEG Encoder
Nethra Imaging has announced its second generation smart camera chips, now available in the industry's smallest package for low power, handheld consumer devices. The NI-2065/66 programmable image processor family can be integrated into camera module designs and handsets, providing consumers with "print quality" images from less expensive optics and digital still camera-like functionality from their mobile devices.
The NI-2065/66 family is currently in production and includes a JPEG encoder for enhanced compression capabilities leading to high frame rate captures, hence reducing blur and storage time. Built on a 0.13-micron process and boasting low power, the NI-2065/66 image processors fit into a 5mm x 6mm package. This allows camera module designers to achieve form factors as small as 8.5mm x 8.5mm, making them optimal for the smallest consumer devices. Use of the NI-2065/66 allows OEMs to develop smart camera modules faster than with alternative solutions, expediting time-to-market. Sophisticated true-color processing allows picture calibrating/ tuning to meet regional taste, while support for multiple sensors helps simplify the OEM's supply chain.
The core architecture of the NI-2065/66 is based on Nethra's second generation real-time image processing pipeline that allows OEMs to develop a platform relevant to various imaging applications. The second generation imaging pipeline has been optimized to work with small-pixel size sensors, achieving print-level image quality even with pixels as small as 1.75 microns.
The imaging pipeline has been designed to work at 75 megapixels/sec giving up to 20 frames per second throughput at 3.2 megapixel still capture (sensor dependent), and greater than 30 fps at 1280x720P HD resolution video capture. The JPEG encoder enables the NI-2065/66 to work with baseband, multimedia and applications processors that have camera ports running at slower speed.
As part of the total solution, Nethra has incorporated a number of digital still camera-like features in the firmware to enhance the consumer's experience. These include image stabilization mode to reduce image blur, NightMode to extract details in low light, continuously variable frame rate, 30 fps preview, fast auto focus time, and Sportsmode to reduce object motion blur. The NI-2065/66 also includes an AdaptiveEye feature that provides shadow enhancement to bring out the details in low intensity, high intensity and backlit environments. A front end scaler provides a special preview mode that allows the sensor to stay in the full resolution mode, thus resulting in better image quality and saving power in the preview mode. In addition, Nethra's flexible programmability features allow for IQ tuning and modifications to meet customers' unique requirements.
The NI-2065/66 is available to customers with full development tool support, including both hardware and software. The kit includes Nethra's ISP EnVision development platform, the Nethra Imaging Camera Control (NICAM) proprietary PC application, and all necessary documents and support. NICAM is developed for customers to calibrate their system to achieve high image quality when using the NI-2065/66 with various sensors.
