Canon, the Japanese camera manufacturing giant recently launched there 250 Megapixel(19,580 x 12,600 pixels) cmos sensor in Tokyo at 7th September, 2015. The sensor is an APS-H-size (approx. 29.2 x 20.2 mm) has also set the world record for the maximum number of pixels in a Cmos sensor less that 35mm in size.
Cannon also claims that the sensor can take images in which letters can be distinguished on the side of the plane, the location of the airplane being 18kms away from the sensor.
High megapixel CMOS sensors generally face problems such as signal delays and slight discrepancies in timing due to high megapixel count and high signal volume. However, the new Cmos sensor with advancements in circuit miniaturization and enhanced signal-processing technology provides an ultra-high signal readout speed of 1.25 billion pixels per second despite of its exceptionally high pixel count.
The camera Sensor can also record Ultra High resolution videos which are 125 times sharper then that of Full HD(1920x1080) and 30 times that of 4K (3,840 x 2,160 pixels) video, which lets users crop and magnify the video without sacrificing image resolution and clarity.
According to Canon the technology wont be used in DSLR's and would be currently used for commercial purposes such as specialized surveillance and crime prevention tools, ultra-high-resolution measuring instruments and other industrial equipment, and the field of visual expression.
