Features a repeating 2×2 pattern with 1 red, 2 green and 1 blue pixels. Tetracell also known as Quad Bayer or 4-cell. For darker scenes, signal processing can combine data from 2x2 pixel groups to essentially act like a larger pixel with a repeating 4×4 subpixel pattern with 4 red, 8 green and 4 blue subpixels.
Pixels are square and is often equal to 1, for example, a 1,000 by 1,000-pixel sensor would have 1,000,000 pixels, or 1 megapixel. On full-frame sensors (i.e., 24 mm 36 mm), some cameras propose images with 20–25 million pixels that were captured by 7.5–m photosites , or a surface that is 50 times larger.
An optical image stabilizer (OIS, IS, or OS) is a mechanism used in still or video cameras that stabilizes the recorded image by varying the optical path to the sensor. This technology is implemented in the lens itself, as distinct from in-body image stabilization ( IBIS ), which operates by moving the sensor as the final element in the optical ...
Typically, f-stops range from f / 1.4 to f / 32 [b] in standard increments: 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, and 32. [15] The light entering the camera is halved with each increasing increment. [14] The distance range in which objects appear clear and sharp, called depth of field, can be adjusted by many cameras. This allows a photographer ...
