Scan-based imaging with variable scan speed using predictions of region-of-interest positions
A method and system for obtaining an image of object, for example an optical section of a sample, are disclosed. The image includes a plurality of scan lines to be acquired. The method includes, for a current one of the scan lines to be acquired, a step of determining positions of one or more predicted regions of interest along the current scan line based on at least one previously acquired predictive scan line. The method also includes a step of acquiring the current scan line along a scan path in accordance with a variable scan speed profile including at least one slower speed component along segments of the scan path corresponding to the positions of the one or more predicted regions of interest and at least one faster speed component elsewhere along the scan path.

IMAGE PROCESSING APPARATUS AND IMAGE FORMING APPARATUS FOR CONVERTING RESOLUTION OF DOCUMENT IMAGE
An image processing apparatus includes an intermediate image generator configured to generate intermediate image data with the same resolution in both scanning directions by performing resolution conversion on read image data obtained by reading a document with a document reading device, a character area detector configured to detect a character area within an image represented by the intermediate image data, an image corrector configured to correct the intermediate image data so that a density of low-density character areas having a density lower than a predetermined reference density is increased and a density of high-density character areas having a density higher than the reference density is decreased in the character area, and an output image generator configured to convert the resolution of the corrected intermediate image data into a predetermined output resolution and generate output image data.
