Abstract:
An image input device comprising a scanner portion and a scanner controlling portion, wherein:said scanner portion includes a reading sensor having controllable resolution converting means for defining a variable resolution to read an image, the variable resolution being defined not higher than a given maximum resolution, and image processing means for processing data of said image read by said sensor; andsaid scanner controlling portion includes resolution designating means for designating a sensor reading resolution to control said controllable resolution converting means, and resolution interpolating means for executing a resolution interpolating process for the output image data of said image processing means; andmeans, responsive to said maximum resolution of said sensor and a sensor reading resolution which is designated by said resolution designating means and which is not higher than said maximum resolution, for enabling said reading sensor to read with the designated resolution independently of said resolution interpolating means.
