  • Patent number: 8154635
    Abstract: An image sensor and digital gain compensation thereof. The image sensor includes a variable amplification device for amplifying an inputted analog image signal as a variable first gain value, an analog-to-digital conversion unit for converting the amplified analog image signal into a digital image signal, and a digital gain compensation device for comparing the first gain value with a reference gain value and compensating the digital image signal as a digital second gain value when the first gain value is less than the reference gain value.
    Type: Grant
