Megapixel

Megapixel, one million pixels, refers to the number of dots in a digital cameras and other digital displays. The megapixel measurement reflects the ratio of individual pixels in a screen as it is divided by one million. In simple terms, a megapixel tells a photographer the camera’s capacity to detail an image.

For example, a camera that renders a 2020 x 1440 (2020 x 1440 = 2,908,800) read will have 2.9 megapixels. Digital cameras tend to produce images at 2048 x 1536 pixels, which renders a 3.1 megapixel measurement. The higher the megapixel number, the greater the resolution of the digital image. Images with higher resolutions appear clearer, sharper and more vivid.

Images that consist of a single megapixel divide up pixel color the following way: 500, 000 pixels are green while both red and blue consist of 250, 000 pixels each.
