According to Oregonian reports, computer scientist Russell Kirsch invented the pixel and scanned the world’s first digital photo. 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 phones and computer screens) were not an obvious innovation in 1957, when Kirsch produced a small 2 by 2 inch for its pixels. Black and white digital image Son Walden (Walden) when he was young. This is one of the first images he scanned into a computer using a device created by a research team from the National Institute of Standards and Technology (now the National Institute of Science and Technology).

An article on Kirsch published in Science in 2010 said: “This work” laid the foundation for satellite imagery, CT scans, virtual reality and Facebook. “Subsequently republished by Wired magazine. 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 functions 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 square 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: “pixelization”.

“Squaring is a logical thing,” Kirsch told The Magazine in 2010. Since then, everyone in the world has been suffering, which is really stupid. “

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 University, 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.
