estimating the spectral sensitivity of a digital sensor using calibration targets
A digital sensor which is used inside a digital camera usually responds to a range of wavelengths. The response of the sensor is proportional to the product of the irradiance falling onto the sensor and the sensitivity of the sensor integrated over all wavelengths. Knowledge of the sensor's response function is important for colorimetry and the research area of color constancy. Such data may not always be available from the manufacturer of the camera. The sensitivity of the imaging device is a result of the hardware properties of theimaging chip, the lens and filters used, and the post-processing done by the processor contained inside the camera. We will be using an evolution strategy to obtain the sensor response curves of a camera given a single image of a calibration target.
