pikseliarvo

Pikseliarvo refers to the numerical value assigned to a single pixel in a digital image. This value represents the intensity or color of that pixel. In grayscale images, a pikseliarvo typically ranges from 0 (black) to 255 (white), with intermediate values representing shades of gray. For color images, pikseliarvo is often represented using color models like RGB (Red, Green, Blue). In RGB, each pixel has three values, one for the intensity of red, one for green, and one for blue. These values are usually in the range of 0 to 255 for each color channel, allowing for millions of possible color combinations. Some image formats might use different bit depths, meaning the range of pikseliarvo can be different. For instance, a 16-bit image would have a larger range of possible values per channel, allowing for more subtle color gradations. The interpretation and manipulation of these pikseliarvo are fundamental to digital image processing, enabling operations such as adjusting brightness, contrast, and applying filters.
