1. A compensation method for an image capture device which includes an image sensor which has a tunable spectral response and which is tunable in accordance with a capture mask, wherein the method compensates for spatial non-uniformity in color sensitivity of the image sensor, the method comprising: applying a default capture mask to the image sensor; capturing a sample image using the image sensor tuned by the default capture mask; analyzing color of the sample image to identify spatial non-uniformity in color sensitivity of the image sensor; constructing a compensation capture mask for application to the image sensor, wherein the compensation capture mask is constructed using calculations based on the identified spatial non-uniformity so as to compensate for spatial non-uniformity in color sensitivity of the image sensor; and storing the compensation capture mask in a memory of the image capture device for application of the compensation capture mask to the image sensor.
