India's No.1 smartphone selling brand Xiaomi has announced another mid-range device Redmi Note 7 pro on Feb 28th. Redmi Note 7 Pro is an interesting device as its specifications are high enough to make a smartphone worth the price. The biggest thing here is the 48MP camera, Does it really have 48MP or a gimmick? ↙
Before we get into the details of 48MP camera lets talk about, how camera sensors really work? Usually, pictures are captured by Red, Green, and Blue color pixels using camera Sensor. A camera sensor is covered by a filter of 25% red, 25% blue and 50% green pixels in a single layer. These pixels are used to capture true colors based on the number of pixels in the camera sensor.
But Redmi Note 7 Pro uses Sony IMX586 camera sensor supporting enhanced imaging on smartphones. Instead of a single filter, Sony has used Quad Byer color filter array which technically uses adjacent 2*2 pixels of the same color. So the Sony IMX586 sensor uses 4 layered pixels of Red, Green, and Blue. Take a look at the picture to know how pixels are arranged.
Sony has claimed that these 4 pixels will convert the image using Array conversion to a single picture.
