242megapixel
242megapixel refers to a very high resolution image sensor, meaning it is capable of capturing an image with approximately 242 million pixels. A pixel is the smallest controllable element in a picture. The total number of pixels in an image is the product of its width and height in pixels. Therefore, a 242-megapixel sensor would have a very large number of individual light-sensitive sites.
Such high resolutions are typically found in specialized applications rather than consumer-grade digital cameras. For instance,
