According to Oregonian reports, Russell Kirsch, who invented the and scanned the world’s digital photo, was world-renowned. He died on August 11 at his home in Portland, Oregon. He was 91 years old.

Pixels (digital dots used to display photos, videos, etc. on mobile and computer screens) were not an obvious innovation in 1957, when Kirsch created a 2 by 2 inch for his work. Small black and white digital son Walden (Walden) when he was young. This is one of the first he scanned into a computer using a device created by the research team of the National Institute of Standards and Technology (now the National Institute of Science and Technology).

An article on Kirsch published in Science in 2010 stated that this work “lays the foundation for satellite imagery, CT scans, virtual reality, and . The article was subsequently published by Wired magazine. (Wired) Republished. The article said that the first square image was only 176 pixels per pixel. Side-less than 31,000 pixels in total. Today, the digital camera on the iPhone 11 can capture approximately 12 million pixels per image.

Although the capabilities of computers have multiplied and can now be carried in our pockets, since then, the scientific community has begun to accept the fact that Kirsch makes pixels straight. The squareness of pixels means that the image elements look blocky, awkward or jagged-usually not as smooth as in real life. There is even a word about this effect: “pixelation”.

Kirsch told the Magazine in 2010: “Squaring is a logical thing. Of course, logical things are not the only possibility…but we use squares. Since then, everyone in the world has been doing It is very stupid to suffer.”

Kirsch then developed a method to smooth the image by using pixels with variable shapes instead of squares.

Kirsch was born in Manhattan in 1929, the son of Jewish immigrants from Russia and Hungary. He was educated at New York , Bronx High School, Harvard University, and Massachusetts Institute of Technology, and served as a research scientist at the National Bureau of Standards for five years.

Russell Kirsch was spared by his 65-year-old wife Joan. Composed of children Walden, Peter, Lindsey and Kara; and four grandchildren.
