Abstract: For correcting a defective portion in image data having a plurality of pixels, a plurality of first target pixels are selected one after another from normal pixels. Any defective pixel is detected within a predetermined area extending about each selected first target pixel as its center and also a normal pixel present on an extension line connecting the first target pixel and the defective pixel is detected and set as a second target pixel. For each defective pixel present between the first target pixel and the second target pixel, an interpolation value is calculated. Further, for each pair of the first target pixel and the second target pixel, a weight coefficient is calculated. The technique stores such plurality of interpolation values and weight coefficients. Then, by using the weight coefficient, a weighted average value of the interpolation values for each defective pixel is calculated and this weighted average value is used for the correction of each defective pixel.

Abstract: An image processing apparatus has an image processing section for synthesizing image information in the form of digital signals and template information. The apparatus stores in advance the template information having a reference posture set to correspond to either a horizontal posture or a vertical posture of the image information. The vertical and horizontal postures have different vertical and horizontal sizes from each other. The template information thus stored is rotated by rotation processing section in accordance with the posture of the image information. During this rotation process, the template information is converted by a conversion processing section according to a predetermined rule.

A normal pixel is searched and detected on each of opposed sides across the target pixel along each of a plurality of search lines extending through the target pixel. There are calculated a first pixel value ratio which is a ratio between a pixel value of one normal pixel located on one side across the target pixel and a pixel value of a further normal pixel located on the other side across the target pixel, a second pixel value ratio which is a ratio between the pixel value of said one normal pixel and a pixel value of the target pixel after the luminance adjustment thereof, and a third pixel value ratio which is a ratio between the pixel value of the further normal pixel and the pixel value of said target pixel after the luminance adjustment thereof. A weight coefficient for each search line is calculated, based on the first, second and third pixel value ratios.

Abstract: One target pixel is selected from a plurality of defective pixels. By adjusting a searching interval based on the number of pixels included in image data to be processed, one or more normal pixels are searched and detected on each of opposed sides across the target pixel along each search line.

Then, by using the interpolation value for the target pixel for each search line and the weight coefficient, a weighted average value of the interpolation value is calculated to be used in correction of the target pixel.
