Sandor L. BarnaOne key to customer acceptance of CMOS imagers in the mobile market space is low-light performance. This is often specified in terms of the lowest light level at which the sensor produces an image with a minimally "acceptable" signal-to-noise ratio. This value is highly customer- and application-dependent, with high-end digital still cameras requiring better performance than low-end video cameras. In enhancing the signal-to-noise ratio, the designer rarely has the opportunity to improve the input signal level. The signal level at each pixel will be proportional to the scene lighting...Read full articleRelated content from Photonics MediaArticlesVCSELs Increase Power and Wavelength for 3D SensingFor vertical-cavity surface-emitting lasers (VCSELs), the future looks bright — because their performance is rising while their price is falling.
