What nationality is the inventor of pixel and who is he?

The inventor of Pixel is Russell A Kirsch (1929-2020), who is of Jewish descent and was born in Manhattan, new york. His father was an immigrant from Russia and Hungary. Russell 1946 graduated from Bronx Science High School in new york, 1950 entered new york University, 195 1 joined the American National Bureau of Standards. Become a member of Standard Oriental Automatic Computer (SEAC) team. 65438-0952 entered Harvard University and then MIT. In 1957, Russell SEACnd's researchers developed a 5? 5 cm small digital image scanner. Subsequently, Russell scanned the film negative of his three-month-old son Walden Lake with a computer and got 179? 179 digital image, which is almost the capacity limit that computers can store at that time, and it is also the first one in history? Digital photos? .

Explained in an archived article in the National Museum of Standards and Technology:? The scanner uses a rotating drum and a photomultiplier tube to sense the reflection of small images mounted on the drum. The mask placed between the picture and the photomultiplier tube embeds the image into discrete pixels. Initially, these images were binary, capturing only black or white, but Russell and his team found that by scanning the images several times at different thresholds, they could superimpose multiple scanned images to generate a grayscale image. This technology enables Russell and his team to develop algorithms that lay the foundation for image processing and image pattern recognition. Russell's variable shape pixel technology makes the image with obvious sawtooth shape smoother by changing square pixels into more natural shape pixels.

Even after Russell 200 1 retired, he never stopped improving his invention. 20 10 Russell published a detailed article in Wired magazine. He also tried to eliminate square pixels in the world and was the originator of pixels.
