Pikselitarkkuutta

Pikselitarkkuutta refers to the level of detail or clarity achievable in a digital image, determined by the number and density of individual pixels it contains. A higher pikselitarkkuutta means more pixels are used to represent the image, resulting in a sharper and more detailed depiction. Conversely, a lower pikselitarkkuutta leads to a coarser, more blocky appearance, especially when an image is enlarged.

The concept is crucial in various digital media applications, including photography, graphic design, and display technology. For instance, when capturing a photograph, a higher resolution camera sensor (which captures more pixels) will generally produce an image with greater pikselitarkkuutta. Similarly, computer monitors and television screens have varying pikselitarkkuutta, often expressed as resolution (e.g., 1920x1080 pixels), which dictates how finely detailed images can be displayed.

In digital art and editing, understanding pikselitarkkuutta is essential for maintaining image quality during manipulation and for preparing images for specific output mediums. For example, an image intended for large-format printing will require a significantly higher pikselitarkkuutta than one meant for a small web display. When an image is scaled up beyond its native pikselitarkkuutta, the individual pixels become visible, leading to a loss of sharpness and detail. This phenomenon is often referred to as pixelation.
