Abstract
A scanning device comprises a controller that determines a resolution of an output image, for example the native resolution of a printer. The controller also determines a resolution of an input image based on the resolution of the output image, s that the definition of the input image is equal to the definition of the output image. The controller then controls the resolution of a scanner according to the resolution of the input image.
Claims28
A scanning device that generates image data, comprising:
- an output resolution determining circuit that determines at least one output resolution from one of a vertical output resolution and a horizontal output resolution of an output image;
- an output dimension determining circuit that determines at least one output dimension of an output image;
- at least one dimensions multiplier that multiplies the at least one output resolution by the at least one output dimension to obtain at least one output definition;
- an input resolution determining circuit that determines at least one input resolution from one of a vertical input resolution and a horizontal input resolution of an input image based on the at least one output definition by dividing the at least one output definition by an input dimension of an image to be scanned;
- and
- an input controller that controls at least one input resolution of a scanner according to the at least one input resolution.
