värivääristyminä

Värivääristymä is a Finnish term that translates to color distortion or color aberration. It refers to unwanted color shifts or artifacts that can occur in an image or display. These distortions can arise from various sources, including the optical properties of lenses, limitations in digital sensors, or errors in image processing algorithms. In photography and videography, chromatic aberration is a common type of color distortion where different wavelengths of light are not focused to the same point. This can result in a halo or fringe of color, typically purple or blue, around bright objects. Digital displays can also exhibit color distortion due to the way pixels are manufactured, the viewing angle, or the calibration of the display. In computer graphics, color distortion might occur during rendering or compression processes, leading to inaccurate color representation. Understanding the causes of värivääristymä is crucial for image quality assessment and for implementing corrective measures in optical systems and digital workflows.
