The present invention relates to the automated and semi-automated cropping of electronic images, and in particular to an apparatus and a method of using an electronic camera to capture and crop such electronic images. An electronic imaging processing device (1) for cropping an electronic image comprises an image processing means (6,8), the image processing means including an electronic processor (6) and firmware and/or software for processing the electronic image. The device (1) processes the electronic image to identify one or more features relevant to the composition of the electronic image, each such feature having one or more compositionally significant properties from amongst a plurality of different predetermined compositional properties, and each such feature occupying a sub-region of the electronic image. Then the device (1) selects one or more compositional rules from a set of predetermined compositional rules, based on the relevance of the compositional rule(s) to the compositionally significant properties of one or more of the identified features. Then the device (1) determines one or more suitable crop boundaries by applying one or more of the selected compositional rules.
