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: There is provided a scanning line interpolation device which is capable of providing an interpolated image with increased reproducibility of vertical high-frequency components in a still picture part. Preceding-field image data is stored in a field memory, and thereafter reference pixels which are located in an interpolation pixel position and its surrounding positions and required for interpolation are extracted from the preceding-field image data stored in the field memory and current-field image data. An inter-field motion judgement portion detects whether or not there is a motion of an image between preceding and current fields based on the extracted reference pixels. If the inter-field motion judgement portion detects that there is a motion, a selection circuit selects in-field interpolation data calculated in an in-field interpolation value calculation circuit from the current-field image data among the reference pixels. If the inter-field judgement portion detects that there is no motion, the selection circuit selects the preceding-field image data located in the interpolation pixel position among the reference pixels. Then, the selection circuit outputs the selected data as interpolation pixel image data.

Abstract: An apparatus and method are disclosed for displaying an image having high frequency components. The image is displayed on a display device that includes a plurality of display elements arranged in both horizontal and vertical directions. The display elements represent colors, such as red, green and blue. A pixel data generator generates for each display element first pixel data corresponding to the luminance levels of red, green and blue colors in the image. A smoothing filter eliminates false colors in the image by applying weighting coefficients to the first pixel data to modify the luminance levels of the first pixel data, thereby producing second pixel data having second color element data corresponding to luminance levels of the respective colors. Each display element of the display is driven in accordance with the second color element data.

Abstract: The frequency of the dot clock in an image display device is adjusted by calculating a first image characteristic from the differences between adjacent picture elements, varying the phase of the dot clock, determining whether the frequency of the dot clock is correct from the way the first image characteristic varies according to the phase of the dot clock, and changing the frequency if it is incorrect. The first image characteristic is, for example, the maximum difference, the histogram distribution of the differences, or a ratio calculated from the histogram. The phase of the dot clock may be adjusted according to a second image characteristic, such as the difference between a single pair of pixel values, which is also measured over a range of dot-clock phase settings.
