Electronics company Canon has developed a 250 megapixel sensor for use in digital cameras. Canon said the sensor is sensitive enough to read lettering on the side of an aircraft 18km (11.1 miles) away.
However, it added, the gadget was 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. The individual pixels on the sensor are about 1.5 microns across – approximately the same size as those found on consumer cameras.
