New Chip: Better Digital Pics For Less Power

Facebook X LinkedIn Email
ROCHESTER, N.Y., Dec. 21 -- A pair of newly patented digital imaging and compression technologies developed at the University of Rochester may soon enable imaging chips to need just a fraction of the energy used today and also capture better images -- all while enabling cameras to shrink to the size of a shirt button and run for years on a single battery. The researchers say that, placed in a home, the chips could wirelessly provide images to a security company when an alarm is tripped, or even allow mapping software like Google's to zoom in to real-time images at street level. The enormous...Read full article

    1. A localized fracture at the end of a cleaved optical fiber or on a glass surface. 2. An integrated circuit.
    image
    In optics, an image is the reconstruction of light rays from a source or object when light from that source or object is passed through a system of optics and onto an image forming plane. Light rays passing through an optical system tend to either converge (real image) or diverge (virtual image) to a plane (also called the image plane) in which a visual reproduction of the object is formed. This reconstructed pictorial representation of the object is called an image.
    pixel
    A pixel, short for "picture element," is the smallest controllable element of a digital image or display. It is a fundamental unit that represents a single point in a raster image, which is a grid of pixels arranged in rows and columns. Each pixel contains information about the color and brightness of a specific point in the image. Some points about pixels include: Color and intensity: In a colored image, each pixel typically consists of three color channels: red, green, and blue (RGB). The...
