When did Kirsch, the inventor of pixel, die?

Portland, Oregon—It is reported that Russell Kirsch, a computer scientist who invented pixels and scanned the world's first digital photo, died at his home in Portland, Oregon on August 1 1 at the age of 9 1.

Pixel (a digital point used to display photos, videos, etc. On mobile phones and computer screens) is not an obvious innovation in 1957, when Kirsch made a small black-and-white digital image of Walden's pixels when he was a child.

This is one of the first images he scanned into the computer using the equipment created by the research team of the National Bureau of Standards (now the National Institute of Science and Technology).

Kirsch 8 1 year-old research mask system;

Kirsch never stopped improving his most famous invention, even after he retired at 200 1. In an interview with Wired on 20 10, he outlined his attempt to create a system using "variable shape pixels" instead of a square that has been dominant since he invented digital imaging. ?

In that interview, he called the square a "logical thing", but he lamented that the decision was "a very stupid thing, and everyone in the world suffered greatly from it". ?

So, at the age of 8 1 year, he began to study a masking system, which can create 6×6 pixel areas, then intelligently divide these areas into two parts with the highest contrast, and then fuse the pixels on both sides of the gap again, but his idea did not catch on.
