Canon Also Publicly Debuts “PHIL,” the Company’s Computer-Vision Artificial Intelligence Engine

MELVILLE, NY, February 11, 2021– According to a recent report from Keypoint Intelligence, 1.4 trillion photos were taken worldwide in 2020 and 7.4 trillion images were stored1. With these staggering numbers, it could be overwhelming for the average consumer to decide what photos are best to keep and store. Delivering expert photo advice in the form of an app, Canon U.S.A., Inc., a leader in digital imaging solutions, today announces its Photo Culling app. Compatible with iOS devices2, this brand-new app helps determine a user’s best photos based on scores against four models: sharpness, noise, emotions and closed eyes, using Canon’s Computer Vision Artificial Intelligence Engine known as “PHIL” (abbreviated for Photography Intelligence Learning) 3. Additionally, the app will suggest deleting duplicative photos, making it easy for the consumer to free up space on their smartphone.

"In today's ever-changing and overwhelming world, where thousands of photos are captured and stored in a person’s smartphone, consumers need an expert, reliable and intuitive photo tool to help them decide the best photos based on years of trusted knowledge and technology,” said Tatsuro "Tony" Kano, executive vice president and general manager of the Imaging Technologies & Communications Group of Canon U.S.A., Inc. “Canon U.S.A.’s new Photo Culling App is the answer and we are proud to see how the company’s Computer Vision technology within this app can assist consumers with finding and keeping their best photos of their fondest moments."

The Photo Culling app features two culling options:
  • Whole Culling: Determines the best photos based on the absolute best scores against the four models: sharpness, noise, emotions and closed eyes. If the score is over the threshold the user sets, the photo is considered to be the best. The remaining images would be suggested as deletions.
  • Similar Culling: Determines the best photos based on score comparison among a similar group of photos. The highest-scoring photos within the group are considered the best photos. A second photo may also be selected as the second-best photo within the group. The remaining images would be suggested as deletions. The app is also able to find similar photos and group them together. For example, If a user selects 10 photos of a dog and 10 photos of a sunset, it will break the photos into two groups and find the best photo of each; one of the dog and one of the sunset.

In addition to its culling options, the Photo Culling app also features:
  • Photo Counts and Storage: Shows the number of photos a user has as well as the amount of phone storage on the Home Screen
  • Event Album: Categorizing and placing photos in albums on the Home Screen. These are dynamic albums based on events/date throughout the year and the app will pull events that have a large number of photos and suggest the user review these photos to delete and save space
  • Features in the Setting Screens: Displaying the number of photos deleted, the current subscription plan (see details below), option for notifications, parameter setting for each score against sharpness, noise, emotion and closed eyes. Users also can adjust these settings, such as changing how much of an impact noise has on a photo versus closed eyes4
  • Dark and Light Mode Settings Screen Option: Displays screens either as a dark or light mode option

Price & Availability*
Available for download via the App Store, the Photo Culling app will be available under two subscription options: $2.99 per month or $14.99 for the year, each with a three-day trial5. For more information, please visit, usa.canon.com/photo-culling-app.

Canon Celebrates Milestone with Production of 150 Million RF And EF Lenses

Canon Celebrates Significant Milestone with Production of 150 Million Interchangeable RF And EF Lenses
Canon Celebrates Significant Milestone with Production of 150 Million Interchangeable RF And EF Lenses

MELVILLE, NY, February 3, 2021– Canon U.S.A., Inc., a leader in digital imaging solutions, announced today that its parent company, Canon Inc., reached a new lens-manufacturing milestone with the production in January 2021, of the Company’s 150-millionth RF and EF series interchangeable lens for EOS cameras1— an RF70-200mm F2.8 L IS USM telephoto zoom lens (released in November 2019).

Production of interchangeable EF lenses for Canon EOS-series AF (Autofocus) single-lens reflex film cameras began in 1987 at the Company’s Utsunomiya Plant. Over the years, EF lenses have gained support from a wide range of users and production has since expanded to a total of four manufacturing bases, including Canon Inc., Taiwan; Canon Opto (Malaysia) Sdn. Bhd.; and Oita Canon Inc. in southern Japan.

EF lens production passed the 10-million-unit mark in 1995 and crossed the 50-million-unit threshold in 2009. In April 2014, the Company celebrated its first-in-the-world achievement of having manufactured 100 million interchangeable lenses, and now, setting a new world record for the most interchangeable lenses produced, Canon manufactured its 150-millionth RF and EF lens in January 2021. Laid end-to-end2, all of the RF and EF lenses Canon has manufactured thus far would measure approximately 7,736 miles in length — nearly equivalent to the Earth’s diameter, which measures approximately 7,917 miles.

Canon’s proprietary EF lenses, launched in March 1987 along with the EOS SLR camera system, have continued to evolve since their introduction, leading the industry through the incorporation of a wide range of innovative technologies, including such world’s firsts3 as the Ultrasonic Motor (USM), Image Stabilizer (IS) technology, and a multilayered diffractive optical (DO) element.

In 2018, Canon introduced the EOS R system and the RF series lenses, which pursues new heights of quality under the core concept of “Speed, Comfort and High Image Quality.” Today, the Company’s extensive RF and EF lens series lineup currently comprises a total of 118 models4, expanding the possibilities for image capture. In addition, thanks to the extensive lineup of lenses, Canon has maintained the number one market share for digital interchangeable-lens cameras since 2003 — a total of 17 years5— and in September 2019, the Company celebrated the production of 100 million EOS-series interchangeable-lens cameras.

Canon will continue refining its imaging technologies centered on its RF and EF lens lineup, striving to cater to the varying needs of photographers — from first-time users to advanced amateurs and professionals — while contributing to expanding the photographic and video imaging culture.

EF400mm f/4 DO IS USM9

Dec. 2001

World’s first7 use of a diffractive optical (DO) lens element

Diffraction is an optical phenomenon in which light waves bend as they pass around the edges of an object. DO lens elements use this phenomenon to correct for a variety of aberrations by controlling the path that light travels.

EF24mm f/1.4L II USM

Dec. 2008

World’s first10 use of Subwavelength Structure Coating (SWC)

SWC technology helps to minimize reflections by aligning countless wedge-shaped structures more minute than the wavelength of visible light on the surface of a camera lens.

EF100mm f/2.8L Macro IS USM

Oct. 2009

World’s first7 use of Hybrid IS, which compensates for both angle camera shake and shift camera shake

Employing an algorithm, Hybrid IS optimally adjusts for camera shake based on information gathered by two sensors located in the lens. By precisely driving the optical correction system, the technology simultaneously corrects for angle and shift camera shake.

EF8-15mm f/4L Fisheye USM

July 2011

World’s first7 fisheye lens to deliver both 180-degree diagonal angle of view and 180-degree circular fisheye

The EF8-15mm f/4L Fisheye USM enables the capture of images with dramatic deformations, exaggerated perspectives and extreme depths of field, making possible images that are significantly distorted, similar to what a fish might see were it to look skyward from under the water surface.
