Basic Concepts

  • Exposure time: It is the period during which the sensor accumulates electric charges. It starts when the sensor pixel starts exposure and ends when the battery level is read.
  • Exposure gain: It is the total amplification coefficient for the output electric charge of the sensor. The exposure gains include the digital gain and analog gain. Analog gain is preferred because it produces low noise.
  • Aperture: The aperture changes the central hole size of the lens.
  • Exposure gain: It is the total amplification coefficient for the output electric charge of the sensor. The exposure gains include the digital gain and analog gain. Analog gain is preferred because it produces low noise.
  • Color temperature: It is defined based on the absolute black body. When the radiation of a light source is identical to the radiation of the absolute black body in the visible region, the temperature of the black body is the color temperature of the light source.
  • White balance: The white objects have a blue or red cast at different color temperatures in sensors. The white balance algorithm is used to adjust the strength of R, G, and B channels to obtain the actual white color.
