Abstract
Methods and systems for reconstructing images from sensor data are provided. In one example, a method comprises: receiving input data generated by photodiodes each associated with a channel having a target wavelength range for photon-to-charge conversion; obtaining, for each channel, a plurality of channel coefficients, the plurality of channel coefficients being configured to, when combined with the input data to generate channel output data for the each channel, increase a main component of the channel output data contributed by a part of the incident light within the target wavelength range of the each channel with respect to a crosstalk component of the channel output data contributed by a part of the incident light out of the target wavelength range; and generating, for the each channel, the channel output data based on combining the input data with the plurality of channel coefficients to reconstruct an image for the each channel.
