pikselöityneeseen

Pikselöityneeseen is the Finnish word for "pixelated." It describes a visual artifact that occurs when a digital image is displayed at a resolution lower than its original source, or when an image is scaled up too significantly. This results in the individual pixels, the smallest units of color on a digital display, becoming visibly apparent as distinct squares. Instead of a smooth transition between colors and shapes, the image appears blocky and coarse.

This phenomenon is commonly encountered in digital photography, video, and graphic design. When a low-resolution image is enlarged, the software attempts to fill in the missing detail by repeating existing pixel colors, leading to the characteristic blocky appearance. In some artistic contexts, pixelation can be an intentional stylistic choice, harkening back to the aesthetics of early video games and low-resolution displays. However, more often, it is an undesirable artifact indicating a loss of image quality.

To avoid or mitigate pixelation, it is important to work with images at their native resolution whenever possible. When scaling images, using high-quality resampling algorithms can help to produce a smoother result, though extreme enlargement will inevitably lead to some degree of pixelation. Understanding the concept of pixel density and resolution is key to appreciating and managing image quality in the digital realm.
