Canons New Megapixel Camera Sensor
Electronics company Canon has now developed a 250 megapixel sensor for use in digital cameras Canons states that the sensor is sensitive enough to read the lettering on the side of a plane 18km away. However, it added, the gadget will be unlikely to find its way into domestic cameras or smartphones instead the ultra-high-resolution sensor could find a role in surveillance systems or other specialised applications. The sensor measures 29.2mm (1.15in) by 20.2mm (0.79in) – which is smaller than the sensors found on many 35mm digital cameras. Dr Konstantin Stefanov, a senior research fellow at the Open University’s Centre for Electronic Imaging, said it was an “impressive” technical feat to get the sensor working but questioned how useful it would prove to be.
“Sensors can be made bigger, but the question is why you would want them to be bigger, because as they get bigger you have more and more problems,” he said.
