Automotive night vision. An automotive night vision system uses a thermographic camera to increase a driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. Such systems are offered as optional equipment on certain premium vehicles.
An event camera, also known as a neuromorphic camera, [ 1] silicon retina[ 2] or dynamic vision sensor, [ 3] is an imaging sensor that responds to local changes in brightness. Event cameras do not capture images using a shutter as conventional (frame) cameras do. Instead, each pixel inside an event camera operates independently and ...
Manual modes: Manual (M), Program (P), Shutter priority (S), Aperture priority (A). Automatic modes: Auto, Action, Portrait, Night Portrait, Landscape, Macro. A dial with more modes. Most digital cameras support the ability to choose among a number of configurations, or modes for use in various situations.
Exposure (photography) Photographic image taken using a variety of exposures. In photography, exposure is the amount of light per unit area reaching a frame of photographic film or the surface of an electronic image sensor. It is determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in units of lux - seconds ...
Aperture priority. A Nikon-style mode dial showing aperture priority mode. Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a mode on some cameras that allows the user to set a specific aperture value ( f-number) while the camera selects a shutter speed to match it that will result in proper exposure ...
Metering mode. In photography, the metering mode refers to the way in which a camera determines exposure. Cameras generally allow the user to select between spot, center-weighted average, or multi-zone metering modes. The different metering modes allow the user to select the most appropriate one for use in a variety of lighting conditions.
Bulb (photography) Bulb is named for the bulb on detachable rubber pneumatic shutter releases that came with early cameras. With shutters set to "B", the pneumatic release kept the shutter open for as long as the photographer squeezed the bulb—a "Bulb" exposure. The Bulb setting (abbreviated B) on camera shutters is a momentary-action mode ...
