New Canon patent teases variable-exposure sensor tech
posted Wednesday, April 1, 2015 at 12:50 PM EST
A recently published patent from Canon reveals an interesting technology capable of better correcting lens vignetting through the algorithmic-based variable exposure time.
Discovered by Egami, the patent explains the process by which a sensor could compensate for vignetting by selectively exposing different regions of the sensor. According to the patent, the algorithms would be able to adjust to variables, including different focal lengths and aperture values.
It’s not directly stated in the vague wording of the patent, but it’s safe to assume this technology would require new sensor technology.
As with any patent, there’s no guarantee it will ever come to fruition, but something of this significance could have implications far greater than for the uses given in the patent itself. We’ll keep a close eye on any further patents regarding new sensor tech from Canon.
