Pixeliimäärä

Pixeliimäärä, often translated as pixel count, refers to the total number of pixels that make up a digital image or display. A pixel, short for picture element, is the smallest controllable element of a picture represented on a screen. Each pixel has a specific color and intensity value, and together, a grid of these pixels forms the complete image.

The pixeliimäärä is typically expressed as a resolution, such as 1920x1080, which means there are 1920 pixels horizontally and 1080 pixels vertically. Multiplying these two numbers gives the total pixeliimäärä, in this case, 2,073,600 pixels. A higher pixeliimäärä generally results in a sharper and more detailed image, as there are more individual points of color to define the picture.

For displays, the pixeliimäärä is a key specification that determines the screen's resolution. For cameras and scanners, it often refers to the number of pixels in the captured image, which influences the potential detail and print size of the photograph. Understanding pixeliimäärä is fundamental to comprehending digital imaging and display technologies.
