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.

Canon patent activity focuses on digital cameras and related technologies

Our perusal of Canon’s patents issued by the U.S. Patent and Trademark Office shows that there are a myriad of other technologies being developed by this corporation than digital cameras. A couple of patents are related to improvements to head-mounted displays, including one method of creating mixed reality images for a user based on his or her surrounding environment. More comfortable ophthalmic devices and binocular lenses are also featured in a couple of patents that we delve into today. The patent applications of Canon that caught our interest today showcase a singular focus on digital cameras, including a service of generating a customizable photo album similar to the hdAlbum service described above.

Canon’s Diversified Patents: Robotics to Touchscreens and Medical Innovations

In the patent applications filed by this company, we found an interesting trio of printing technologies, including one filing which would protect an improved system for printing and binding booklets. Medical innovations, including an endoscopic tool which can be selectively made transparent and visible depending on endoscopic operation needs, are discussed below. We also noted an innovation for reducing erroneous operations in an electronic device with multiple touchscreen panels. There have been many recent additions to Canon’s already globally renowned patent portfolio that we profile today. We discuss a few patents issued to protect improvements to robotics technologies for manufacturing facilities. A couple of patents show Canon’s interest in improving nanofabrication techniques for creating semiconductors. We also explore inventions related to printing copy-forgery-inhibited patterns and high precision scanning technologies.

The Evolution of Digital Cameras – A Patent History

Just about 40 years ago, a young electrical engineer working at the offices of Eastman Kodak in Rochester, NY, developed a product that would upend the entire world of photography. Since that time, the technology has exploded into consumer markets and has proliferated into our daily lives, from camera components included in smartphones to high-quality megapixel systems which provide professional-grade images. All of this came to be thanks to the development of light-sensitive semiconductor devices capable of storing and transmitting light exposure information to create a digital image.

Canon Invents: Digital Cameras, Video Editing, Medical Imaging

A worldwide leader in the development of camcorders, cameras, photocopiers and other imaging and printing devices, Canon Inc. of Tokyo, Japan, is one of the most active developers of new intellectual properties in the world. Although this article published by Tom’s Guide erroneously reports it as patented, Canon has developed and filed a patent application recently for camera imaging technologies which can better recreate human skin tones in captured images…. Issued patents are the true measure of any company’s intellectual property strength, and Canon’s patenting activities are among the strongest of any corporation operating in today’s world. Digital camera innovations are protected in a couple of patents we explore, including a flash device camera accessory which offers a much longer service life than previous models. We noticed an interesting foray into the world of business documentation services, including one method for allowing multiple clients to interact with a document without being required to install a reader application.

Canon Seeks Patent on Battery Powered Mobile X-Ray Machine

Canon has been involved with developing X-ray technologies in the recent past, as we’ve profiled in our past coverage of this company’s intellectual property portfolio. Previous improvements to X-ray imaging devices that we profiled included improvements to durability, like better resilience to shocks from physical impacts as well as devices with a better capacity for withstanding heat from electrical energy generation. This patent application was filed by Canon with the USPTO in October 2013 to protect a mobile apparatus capable of performing X-ray imaging techniques on a patient. The apparatus is comprised of an X-ray tube contained within an arm that is supported over a cart through the use of a vertical pillar. The bottom portion of the mobile cart includes a wheel and caster system for moving the imaging device from room to room. To provide power for the X-ray device, the cart also includes a battery device on the cart that energizes the X-ray tube through the use of an alternating high-voltage cable.

Canon Seeks Patent on Camouflaged Copy-Forgery Pattern

The featured patent application for this column describes a novel improvement for providing latent-image patterns for protecting secure documents. This system creates more effective watermarks for preventing unauthorized copies that are camouflaged but can transmit important data. We also discuss a series of patent applications for medical devices, including a few upgrades to X-ray imaging devices and a design for a less cumbersome ophthalmologic device for creating an X-ray image of a patient’s eye. Our profile of Canon’s recently issued patents shows a wide range of small improvements to various imaging and printing devices developed by the corporation. One patent protects a new design for copy machines that provides better access for clearing paper jams. Another issued patent protects an inkjet head capable of recycling unused ink droplets escaping the inkjet head. We also discuss a few upgrades to printing software systems, including better methods of storing print job histories while in sleep mode.
