Smartphone

Although smartphone makers push high megapixel counts on their camera stacks, sensor size, lens, elements, and other hardware play a big role too.

Instead of using one photosite to collect color information, it uses a square of four photosites to effectively double the size of the photosite at the cost of final image resolution. Instead, they use a technique called [pixel binning](https://www.androidpolice.com/what-is-pixel-binning/), where the phone's software combines the data from a square of adjacent photosites into a "super pixel." The camera sensor is a piece of hardware that converts raw optical data (light) into electrical information. Some digital cameras experimented with cyan, magenta, and yellow (CYYM) instead of blue, red, and green because it lets more light into the photosites than RGB filters. To extract color data, image sensors cover each photosite with a color filter (typically a matrix of red, green, and blue). The drawback to having more lenses is having less light on the sensor. The lower the focal length (measured in mm), the wider the angle of view. The lens is fundamental to the camera's focal length. [focal length of the camera](https://thesmartphonephotographer.com/smartphone-camera-focal-length/). Instead, the focal length of smartphones is given in 35mm equivalent. Professional cameras can control how much light they receive by adjusting the aperture (the opening between the internal workings of the camera and the outside world).
