Comparison of simplified back-illuminated and front-illuminated pixel cross-sections. A back-illuminated sensor, also known as backside illumination (BI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance.
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in video telephony, live streaming and social media, and security. Webcams can be built-in computer hardware or peripheral devices, and are commonly connected to a device using USB or wireless protocol.
The purpose of bias lighting is to reduce the perceived brightness of the display as a result of the contrast with the slightly illuminated area around it. [1] This reduces the eye strain and fatigue that occurs when viewing a bright display against a very dark background for an extended time, [1] and increases the perceived blackness, perceived highlights, and overall contrast of the display.
For this reason, intelligent lighting (ILS) is also known as automated lighting, moving lights, moving heads, or simply movers. More recently the term has fallen into disuse as abilities once reserved to a specific category of lighting instruments (most notably colour changing and variable focus) have become pervasive across a range of fixtures.
A problem for high-speed cameras is the needed exposure for the film; very bright light is needed to be able to film at 40,000 fps, sometimes leading to the subject of examination being destroyed because of the heat of the lighting. Monochromatic (black and white) filming is sometimes used to reduce the light intensity required.

Light stage is a device used for capturing the shape, texture, and reflectance of a target, usually for virtual cinematography. Light stages are usually a combination of multiple cameras and structured light techniques, and additionally, polarizers are included to find the subsurface scattering component of the target's skin.
