Beeldoutput

Beeldoutput (image output) is the process of delivering visual information to an output device, such as a display, printer, projector, or head-mounted display. In computing, it refers to the final stage of the graphics pipeline, where pixel data that has been rendered or composed is converted into a form that a device can present to a viewer. Beeldoutput encompasses still images as well as dynamic video and real-time graphics.

Output devices and representations vary widely. Monitors and televisions render images as raster grids of pixels with specific resolutions and refresh rates. Printers translate digital images into physical ink or toner on paper, often using different color spaces than screens. Projectors and VR or AR displays provide alternative viewing modalities. The quality of beeldoutput is influenced by device capabilities (resolution, color depth, contrast ratio, brightness), processing latency, and the effectiveness of color management.

Key technical considerations include color management and color spaces (for example, using sRGB or Display P3 for screens and CMYK for printing), gamma correction, and calibration. Bit depth affects smooth color transitions, while resolution and dot pitch determine sharpness. For video and interactive graphics, frame rate, latency, and synchronization are important. Data formats and pipelines also matter, with raster formats (PNG, JPEG) and video streams feeding the display pipeline, while display interfaces such as HDMI, DisplayPort, USB-C Alt Mode, and in older setups VGA carry the signal to devices.

In practice, beeldoutput is about translating digital image data into a perceptible visual experience that faithfully represents the source content within the constraints of the chosen output path.
