What is Pixelation?
Pixelation occurs when an image on your TV screen appears blurred or distorted, usually characterized by visible square blocks or jagged edges. In simple terms, it results from a failure to adequately communicate the video information from the source (like your cable box or streaming device) to the TV screen. While occasional pixelation might be annoying, consistent issues could indicate larger underlying problems.
Understanding the Pixel Structure
What Are Pixels?
To fully grasp pixelation, it’s essential to understand what pixels are. A pixel (short for “picture element”) is the smallest unit of a digital image or display. TV screens are made up of millions of tiny pixels that work together to create a cohesive image. When these pixels function correctly, they display smooth video and high-quality images.
Types of Pixelation
Pixelation can manifest in several ways:
- Blockiness: This occurs when large blocks of pixels do not match the surrounding pixels, leading to a fragmented look.
- Blurriness: While not as severe, blurriness can also be considered a form of pixelation, where the image lacks sharpness, making shapes and edges appear fuzzy.
