Processor offers optimal combination for
SLR
Sigma Corporation has used the Analog Devices Blackfin processor in its SD14 digital single lens reflex (SLR) camera.
Sigma Corporation has used the Analog Devices Blackfin processor in its SD14 digital single lens reflex (SLR) camera Powered by the unique direct-image capabilities of the Foveon X3 sensor and a Blackfin ADSP-BF561 processor, the SD14 can reproduce high-definition images rich in gradation and three-dimensional detail, because the SD14 directly captures red, green and blue data for every pixel in an image, without loss or distortion

Be Here Corporation is using Analog Devices' Blackfin as a critical processor for its collaboration phone solutions integrating video, audio and data into one device.
A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
"The SD14 tells the 'whole truth' about an image, by capturing the real colour of every pixel", says Kazuto Yamaki, Chief Operating Officer, Sigma Corp.
"Analog Devices' Blackfin was the only product capable of meeting our requirements for an image-pipeline processor that could crunch the numbers required for such precision while also managing power consumption to maximise battery life".
Sigma chose the Blackfin ADSP-BF561 processor because it offered an optimal combination of high performance and low power consumption.
The ADSP-BF561 processor comprises two independent Blackfin 600MHz cores, an ideal design for mathematically intensive multimedia applications such as image processing.
The Blackfin's on-chip power management features, including its programmable voltage regulator and PLL, enable low power modes to maximise SD14 battery life.
Data collected from the Sigma SD14 image sensor streams into the image pipeline, where a Blackfin ADSP-BF561 processor executes as many as 200 computations per pixel, running complex image-processing algorithms such as shading and colour compensation, white balancing, tonal and colour correction, sharpening, and compression.
The speed of the image pipeline, from sensor to memory card, must execute very quickly to ready the camera for the next shot, allowing a series of shots in rapid succession.
"The power and performance of Blackfin enabled Sigma to achieve a breakthrough in digital photography".
"We look forward to working with Sigma to stretch the boundaries even further through our continued collaboration and innovation", says Jerry McGuire, Vice President, General Purpose DSP Group, Analog Devices.
