Abstract: Interpolation data for a missing pixel are obtained (4) after a correction (3) for variations in the characteristics of the imaging devices (8(1), 8(2)). The correction for variations in characteristics includes, for example, a black level correction (9) and a sensitivity correction (10). The interpolation includes, for example, interpolation calculations (14(1), 14(2)) such that a mean value of a plurality of pixels including the missing pixel and a mean value of a plurality of pixels not including the missing pixel become equal and an interpolation calculation (14(0)) that takes the mean of the pixels to the right and left of the missing pixel, the calculation with the least error being selected (13, 15). Thus missing pixels in highly periodic images can be properly interpolated, and interpolation can be performed with high precision even when there are variations in the sensitivity characteristics of the individual imaging devices constituting the contact image sensor.

Abstract: 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.

Abstract: Missing-pixel interpolation data are obtained such that the mean value of a plurality of pixels constituting a group of pixels including a missing pixel is equal to the mean value of a plurality of pixels constituting a group of pixels not including the missing pixel. For example, missing-pixel interpolation data are obtained by (1) obtaining a sum (SL) of the values of pixels other than the missing pixel (L) in the k pixels constituting the group (LC) of pixels including the missing pixel, (2) obtaining a sum (SA) of the values of k pixels constituting a group (NA) of pixels not including the missing pixel, and (3) taking the difference between these sums. This makes it possible to reduce interpolation error when a highly periodic image with missing pixels is interpolated.

This provides the enlarged image with adequate high-frequency components, and a sense of resolution of the enlarged image can be obtained.

Abstract: A tone step detector detects whether the tone of n-bit input image data varies gradually, and generates a tone processing control signal indicating that a tone step is contained. A bit shifter bit-shifts the n-bit input image data to the left by ? bits, to generate (n+?)-bit image data. A tone processor smoothes the image data of the (n+?)-bit image data generated by the bit shifter, in the region where the tone processing control signal indicates that a tone step is contained, to generate (n+?)-bit image data having been smoothed in the above-mentioned region. Because of the selective smoothing, degradation in the image quality due to quantization is reduced even when an analog image signal whose tone varies gradually is input.
