pixelaatsioon

Pixelaatsioon is a term used in digital imaging to describe the effect seen when a raster image is displayed at a size much larger than its original resolution. This occurs because the image is composed of individual squares called pixels. When an image is magnified beyond its intended display size, these discrete pixels become visibly apparent, often appearing as jagged edges or blocky patterns.

The appearance of pixelatsioon is directly related to the image's resolution, which is the density of pixels within a given area. A lower resolution image has fewer pixels, meaning each pixel is larger and will become noticeable at a smaller magnification. Conversely, a high-resolution image has more pixels, allowing it to be enlarged to a greater degree before pixelatsioon becomes apparent.

This effect is often undesirable in digital art and photography, as it detracts from the visual quality and clarity of the image. When editing or displaying images, maintaining the original resolution or using appropriate scaling algorithms can help minimize or avoid pixelatsioon. Upscaling algorithms attempt to intelligently fill in the gaps between pixels when enlarging an image, but they cannot perfectly recreate detail that was not present in the original low-resolution data.
