Kodak's Tech Brief for October: Better Digital Pictures through Kodak Color Science

ROCHESTER, N.Y., Oct. 30 -- Eastman Kodak Company's Tech Brief for October explains how its pioneering research in color science contributes to the performance of image sensors in digital cameras - including the company's newest offering, the Kodak EasyShare DX6490 Zoom Digital Camera. Kodak color science technology directs the camera to correct data so that pictures look just like the way we remember them.

Making Image Sensors "See" Color

Sensors detect light, wavelength, and proximity. Unlike the human eye, an image sensor reads this information without interpretation, and this becomes problematic. Scientists have long studied this disparity between sensor and human perception to find ways to adjust sensors' performance and produce images as we perceive and remember them. Kodak pioneered the digital camera and its researchers continue to build on decades of color science and image science expertise to refine the quality of digital image capture. Their work has produced mathematic formulas and software algorithms that tell an image sensor how to use the raw data it collects.

The Kodak EasyShare DX6490: 75 years of Kodak Color Science

It seems as simple as the touch of a button. But the technology inside the Kodak EasyShare DX6490 Zoom Digital Camera is performing multiple interdependent calculations to make raw data detected by the camera's image sensor into pictures as vibrant and crisp as you remember them, based on 75 years of Kodak research. With each click of the shutter, the Kodak Color Science image processing chip quickly and precisely analyzes scene elements. Kodak's research and development efforts are at work in the form of complex, patented algorithms that assess and determine the significance of data to control exposure, white balance and color reproduction.
