This disclosure concerns the determination of improved exposure parameters of an image capturing device, such as a multi-spectral or hyper-spectral camera. A processor receives or determines image values for multiple points of an image and receives first one or more exposure parameters that were used to generate the image values. The processor then determines a distribution of the image values. For each point of the image data the processor then determines an enhanced value by equalising the distribution of the image values. Finally, the processor determines the one or more improved exposure parameters of the image capturing device, such that the one or more improved exposure parameters adjust the received or determined image values towards the enhanced image values. When the exposure parameters are used for capturing a further image, the further image will be enhanced.
