Canon already with more than 300 patents in 2016, pursues plastics and photoacoustic imaging tech

Our latest survey of patents issued recently to Canon include a couple of imaging technologies related to medical diagnostics, such as is the case with the imaging innovation outlined within U.S. Patent No. 9230319, entitled Method of Reconstructing a Biological Tissue Image, and Method and Apparatus for Acquiring a Biological Tissue Image. It protects a method of reconstructing an image of a sample through the use of multiple measured spectra obtained by measuring respective regions of the sample; the method involves acquiring an image through utilization of an intensity distribution in the regions of at least one peak in each of the measured spectra as well as a classifier. This technique is useful in the examination of biological tissues to determine the presence of cancer.

A Patent History of Filmmaking

The history of film is a long one that, by some accounts, extends as far back as the early 1700s and the discovery by German physicist Johann Heinrich Schulze that silver salts react to light exposure by becoming darker in color. By the late 1800s, celluloid film had appeared and the ability to record motion pictures through a camera had become a reality. Indeed, it was none other than George Eastman, who in 1889 perfected the first commercial transparent roll film, one year after the name “Kodak” first began to be used to market his cameras. It was the Eastman flexible film advancement that made it possible for the development of Thomas Edison’s motion picture camera in 1891. Edison called his first generation picture camera a “Kinetoscope,” after the Greek words “kineto,” which means “movement,” and “scopos,” which means “to watch.” Edison filed a patent application on the Kinetoscope on August 24, 1891, and the patent ultimately issued on August 31, 1897.
