Image quality refers to how well an image captures and represents its subject. It is determined by several factors such as resolution, color accuracy, contrast, brightness, sharpness, noise levels, and distortion. In general terms, a high-quality image should have clear details, accurate colors, good contrast, and be free from defects like blurriness or graininess. Image quality is important in photography, video recording, computer graphics, and other visual media because it affects how well the viewer perceives and interprets the content presented.
