An image interpolation device comprises a data storage unit (2) for storing the data in the neighborhood of a missing pixel, a filter interpolation unit (3) for performing a multiply-add computation on the data output from the data storage unit, a limiter processing unit (4) for limiting the data output from the filter interpolation unit to within the range of the data output from the data storage unit, and an interpolation data insertion unit (5) for interpolating the data output from the limiter processing unit into a position corresponding to the missing pixel in the data output from the data storage unit. The image interpolation device is capable of increasing the interpolation accuracy of missing pixels, especially in the interpolation of scanned document data including periodic data. |
