Canon Global Shutter Patent Application

September 30, 2015 By Eric Reagan

One of the major criticisms of DSLRs, and specifically Canon DSLRs, is the use of a rolling shutter that produces motion artifacts. This rolling shutter effect is very prevalent in video with Canon DSLRs thanks to the readout method of the CMOS image sensors.

It has certainly improved with recent models (the 5D Mark II was a mess and the 5D Mark III is much better) but Canon is continuing to refine the process and reveals some of the methods it is seeking to use in a pair of recent patent applications. [Read more…]

Apertus Axiom Camera: Open Source 4K Camera

July 13, 2012 By Eric Reagan

Apertus Axiom

The Apertus Axiom Camera is an open source project that looks to produce a 4K camera with a Super 35 sensor, Cinema DNG files, 150fps at 4K, a global shutter and 15 stops of dynamic range.

The plan is to launch a Kickstarter campaign in the fall to crowdfund the project at a target price “well below $10,000.”

If this camera actually comes to market with those features and price range, it stands to further disrupt the pro video market. Sony’s FS700 really stirred the pot when it was introduced as an $8,000 camera that will (at some undetermined point in the future) shoot 4K footage and capture high frame rate footage (something it will actually do now) in full 1080p HD.

Of course, performance, reliability and support are key components that the Axiom will need in order to become a real player in the market.
