Abstract
An image scanning apparatus is described that includes a sensor having an array of imaging elements that generates a plurality of scan lines of image pixels from an original image. The image scanning apparatus also includes a control module that controls the sensor to generate the scan lines, some of the scan lines are tilted with respect to other scan lines such that some image pixels of any two adjacent lines are not overlapped. An imaging module is also provided in the image scanning apparatus that generates a scan image from the scan lines such that image resolution of the scan image is increased without increasing scan resolution of the sensor. A method of increasing the image resolution of a scan image without increasing the scan resolution of the scanner is also described.
