Abstract
For driving an image sensor having a pixel with a transfer gate formed between a photo-detector and a floating diffusion region, a noise-reducing voltage is applied on the transfer gate during a first period of an integration mode. A blooming current voltage is applied on the transfer gate during a second period of the integration mode. A read voltage is applied on the transfer gate during a read mode after the integration mode. The read voltage has a higher magnitude than the blooming current voltage. With application of the noise-reducing voltage, noise is reduced and a dynamic range is extended for the image sensor.
