Image reconstruction from image sensor output

A method, comprising:

• receiving input data generated by photodiodes of a plurality of sensing units responsive to incident light, wherein each sensing unit comprises one or more photodiodes, each of the one or more photodiodes being 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.

A non-transitory computer readable medium storing instructions that, when executed by a hardware processor, causes the hardware processor to perform:

• receiving input data generated by photodiodes of a plurality of sensing units responsive to incident light, wherein each sensing unit comprises one or more photodiodes, each of the one or more photodiodes being 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.
