  • Dynamic range extension for CMOS image sensors
    Patent number: 6734905
    Abstract: An image sensor for capturing and producing an image includes a photoreceptor array that receives light and produces a signal for each pixel of the image. The image sensor further includes amplification circuitry that amplifies the signals. The amplification circuitry provides two distinct gains for each of the signals to produce two output signal levels. The image sensor also includes a fusion module, which combines the two output signal levels into one signal level. Accordingly, overall dynamic range of the image sensor is increased.
    Type: Grant
