摘要：An integrated circuit for an imaging system is disclosed. In one aspect, anintegrated circuit has an array of optical sensors, an array of optical filters integrated withthe sensors and configured to pass a band of wavelengths onto one or more of the

sensors, and read out circuitry to read out pixel values from the sensors to represent animage. Different ones of the optical filters are configured to have a different thickness, topass different bands of wavelengths by means of interference, and to allow detection ofa spectrum of wavelengths. The read out circuitry can enable multiple pixels under oneoptical filter to be read out in parallel. The thicknesses may vary non monotonicallyacross the array. The read out, or later image processing, may involve selection orinterpolation between wavelengths, to carry out spectral sampling or shifting, tocompensate for thickness errors.
