ABSTRACT:
A method of generating an electronic representation of an original image (2) comprises illuminating the image (2) with a scanning beam; causing relative movement between the scanning beam impinging on the image and the image (2) whereby the original image (2) is scanned in a series of overlapping scan lines. The scanning beam is caused to impinge on one or more arrays of radiation sensitive elements (14-16), each array having dimensions smaller than the dimensions of the image (2), and the elements being sensitive to the intensity of respective portions of the incident beam received from corresponding pixels of the original image within a scan line at least some of which extends transversely to the scanning direction. The sensed intensities are regularly monitored and data related to the intensities monitored in a predetermined number n of the monitoring steps is stored in a memory (20). A predetermined algorithm, such as an edge enhancement, is applied to the stored data to generate enhanced image data and part of the stored data is replaced with the enhanced image data.
