Abstract:
1. An image-processing apparatus comprising: an area sensor unit configured to read image data items corresponding to a plurality of frames from an original image, the image data items having at least one shift corresponding to less than a single pixel; a correction unit configured to correct an inclination of each of the image data items acquired through the area-sensor unit; a high-resolution conversion unit configured to acquire image data with a resolution higher than a resolution used during data reading by performing interpolation processing by using the corrected image data items; a maximum frame number storage unit configured to store data of a maximum number of at least one frame of the image data items acquired through the area sensor unit; a resolution setting unit configured to set a resolution used to output the original image; a necessary frame number acquisition unit configured to acquire a number of at least one frame necessary to perform the high resolution conversion based on a result of the setting made by the resolution determining unit; a read frequency calculation unit configured to calculate a frequency of reading the original image through the necessary frame number acquisition unit and the maximum frame number storage unit; and a read frequency control unit configured to read the frequency determined by the read frequency calculation unit and the original image.
