Kodak’s New Chip Assures Bright Images in Dim Ambience
According to Michael DeLuca, marketing manager for image sensors at Kodak, this innovation will facilitate photographers with almost two extra stops of light sensitivity.
Now, the question arises how this sensor works:
Firstly, sensor functions like this by using a variation on the Bayer filter that decides how most image sensors capture color data.
Secondly, via Bayer filter grid pixels are divided among red- green- and blue-sensitive dots, whereas a filter that allows only a certain frequency of light to pass through each pixel (red, green or blue) and determines the color sensitivity of each dot.
Thirdly, Software algorithms equipped in the camera interpolate the data from adjacent pixels, to offer each pixel in the resulting image an intensity values for each of the three component colors.
After treating luminance (brightness) and chrominance (color) as separate and equally vital properties, DeLuca asserts that company’s this pattern adjoins number of clear, unfiltered pixels that capture information about the overall intensity of light but not its color, to copy it in the same manner as human eye sees.
DeLuca asserted:
What this is really doing is addressing light sensitivity. We’re not impacting what is going on in the fundamental structure of the pixel.
Kodak’s forthcoming plans looks ahead to offer the same associated software algorithms to other chipmakers and to have sample chips by using the same pattern that will get ready early next year.
