System and a method for processing an image

A system for processing an image comprising:

• an image gateway arranged to receive an input image showing a scene composed by a combination of a plurality of image portions of the input image, wherein one or more of the plurality of image portions is associated with an exposure level deviated from an optimal exposure level;
• and
• an enhancement engine arranged to process the input image by applying an exposure/image relationship to the input image, wherein the exposure/image relationship is arranged to adjust the exposure level of each of the plurality of image portions towards the optimal exposure level;
• and to generate an enhanced image showing a visual representation of the scene composed by a combination of the plurality of image portions of the input image with an adjusted exposure level,
• wherein one or more of the plurality of image portions is further associated with loss of details in a visual representation of the image due to an over-exposure level or an under-exposure level associated with the corresponding image portions of the image,
• wherein the enhancement engine comprises an exposure gated detail recovering module arranged to recover visual details in the image portions associated with the over-exposure level or the under-exposure level,
• wherein the enhancement engine further comprises a dynamic range expansion module arranged to expand a dynamic range of the input image,
• wherein the dynamic range expansion module includes a feature fusion module arranged to combine features of remaining image portions of the input image with the optimal exposure level and the image portions associated with the over-exposure level or the under-exposure level with visual details recovered by the exposure gated detail recovering module.
