Eliminating grains at high ISO setting

[tamia]

There's a new chip created by researchers at Stanford that could see in 3D that could lead to better images, especially at higher ISO settings where grain is a big issue. Anyone who shoots with a digital camera that offers adjustable ISO settings has seen the noticeable grain that shows up in images. The quality of the camera will affect how high the ISO setting can go before grainy images are a significant issue.

This new Stanford chip has a three megapixels rating and rather than using one single large sensor, the prototype chip breaks the image up into many small and overlapping 16 x 16 pixel patches known as subarrays.



Kind a confusing. But how does this thing actually works???
Anyone who would like to share?

Uhmmm, as far as what I have read about this new chip, after the photo is taken using the prototype chip processing software in the camera is able to analyze the slight difference in location of common elements in each of the small arrays. The differences in the position of common elements in each array are used to estimate the distance of an object from another object in the frame, like a wall.

Well, this new chip is interesting! It would be nice to see images in 3D I guess. ^_^

Instead of devoting the entire sensor for one big representation of the image, Fife's 3-megapixel sensor prototype breaks the scene up into many small, slightly overlapping 16x16-pixel patches called subarrays. Each subarray has its own lens to view the world--thus the term multi-aperture.

After a photo is taken, image-processing software then analyzes the slight location differences for the same element appearing in different patches--for example, where a spot on a subject's shirt is relative to the wallpaper behind it. These differences from one subarray to the next can be used to deduce the distance of the shirt and the wall.
