Abstract
An image sensor has a plurality of rows and columns of pixels, including RGB and bandpass I filters in a predetermined pattern shifted between adjacent columns so that none of the RGBI filters is adjacent the same type of filter. Each pixel includes a photodiode, a transfer gate and a floating diffusion. The transfer gate for all pixels in a pattern is controlled by the same signal, which can be a separate synchronous control signal controlled based on a predefined integration period or an asynchronous signal generated internally by the bandpass filter I and that is compared to a predefined voltage level indicative of a predetermined intensity at filter I. Upon activation of either signal, the integration period for the pixels ends and the charge on the floating diffusion for the R, G and B pixels is digitized in relation to the bandpass pixel I using a ratio-to-digital converter.
