The rumored Canon 75-megapixel DSLR camera will feature a non-Bayer multilayer sensor, which has been patented by the Japanese company recently.
Canon might introduce a DSLR camera with a 75-megapixel image sensor by the end of 2013. The company’s high-megapixel shooter was supposed to have a sensor providing an image quality of about 50-megapixel, give or take a few megapixels, according to reports from the beginning of this year.
Canon 75-megapixel DSLR camera to use non-Bayer multilayer sensor
Recent leaked information has unearthed the fact that the EOS maker will go beyond this amount and that its fans will most likely witness the launch of a Canon 75-megapixel DSLR camera in 2013
Further evidence about the device and its image sensor has been released, with a trusted source claiming that the camera will be based on a non-Bayer multilayer sensor with a “total usable photosite”.
Bayer multilayer sensor vs Sigma Foveon X3
Bayer filters are based on a square grid which is filled with red, green, and blue photosensors. Half of them are green, while a quarter is reserved to each of red and blue. It is the most common type of image sensors and it is used in a lot of imaging devices.
Recently, Sigma has been making the rounds with a new model called Foveon X3. It is based on three photodiode layers, each one of them responsible for a different color.
Sigma DP Merrill cameras capture photos at 46 megapixels and they are known for not requiring anti-aliasing filters, since the color arrays are separate, thus moiré patterns will not be created.
Recent Canon patent backs the rumors
The information regarding the Canon 75-megapixel DSLR camera not using a Bayer multilayer sensor falls in line with recent details showing that the company has patented a Foveon-like sensor.
The patent was filed in October 2011 and was approved in late May 2013. The Foveon-like image sensor by Canon is capable of absorbing more light and in an even more efficacious way than conventional sensors.
Similar to Sigma’s techology, the Canon module will be more sensitive to red light and it will be capable of outputting an impressive image resolution. For now, the new “EOS 1D” shooter remains hidden, so do not get too excited over rumor and speculation.
