In the read-out phase, these charges are sequentially transported across the chip from sensor to sensor and finally converted to an electric voltage. For quite some time, CMOS image sensors have been available.

8: The context determines how “bright” we perceive an object to be. Both squares have the same brightness, but the square on the dark background appears brighter than the square on the light background. The two squares only appear equally bright if they touch each other. causes problems, however, as soon as we perform arithmetic operations with images. Subtracting two images is a simple example that can produce negative numbers. Since negative gray values cannot be represented, they wrap around and appear as large positive values.

Digital cameras that transfer image data directly to the PC via standardized digital interfaces such as Firewire (IEEE 1394), Camera link, or even fast Ethernet will further simplify the image input to computers. The transfer rates to standard hard disks, however, are considerably lower. Sustained transfer rates are typically lower than 10 MB/s. This is inadequate for uncompressed real-time image sequence storage to disk. Real-time transfer of image data with sustained data rates between 10 and 30 MB/s is, however, possible with RAID arrays.
