Embodiment Construction
>
[0074] In this embodiment, the modified value of Gb is calculated in consideration of the foregoing reasons of the difference, on the basis of the pixel signals of four pixels with different colors which are vertically and horizontally adjacent to the green pixel corresponding to Gb (step S3). Then, Gb, which tends to be larger than Gr in general, is corrected to be smaller by use of the obtained modified value (step S4). Therefore, when a subject with even color is photographed, Gb is so corrected as to be equal to Gr. In other words, it is possible to suppress line crawling without smoothing an image.
[0075] Accordingly, when photographed image data is subjected to processing for suppressing striped noise according to this embodiment, image data after the processing is not smoothed. Thus, it is possible to effectively subject image data to edge enhancing processing. As a result, it is possible to obtain a fine image with sharpness.
[0076] In the step S2, the judging section 54 judg...
