Canon Global Shutter Patent Application


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…]


Canon Develops 250MP APS-H CMOS Sensor

Canon 250MP CMOS Sensor

Canon has announced the development of a 250MP APS-H format CMOS sensor and has a working prototype camera using the super high resolution sensor.

The APS-H format was used in prior Canon 1D models and measures 29.2 x 20.2mm. The sensor resolution is 19,580 x 12,600 pixels. That is 125x greater resolution that 1080p HD video and 30x more resolution than 4K video.

The new CMOS sensor has mind-blowing readout speed of 1.25 billion pixels per second!

While we may scoff today at 250MP, it was only a eight years ago that Canon’s announcement of an in-development 50MP sensor seemed unrealistic. And today, of course, we have the Canon 5Ds.

Hasselblad Unveils 50MP CFV-50c CMOS Back for V System

Hasselblad CFV-50c

Hasselblad has launched a new 50MP back with a 43.8 x 32.9mm sensor size for its legacy V System medium format cameras. The CFV-50c is the new CMOS version of its existing CFV-50 CCD digital back, which also weighs in at 50MP.

The CMOS sensor provides improved noise control and sensitivity with a max ISO 6400, as well as higher frame rates than the previous CCD version. [Read more…]
