The noise reduction circuit restricts a difference between a value of each of peripheral pixels and a value of a center pixel to a value a value having a predetermined noise constant defined as an upper limit with respect to each of the peripheral pixels, e.g., a pixel space of 5×5. The values of the peripheral pixels whose upper limits are restricted are defined as new values of the peripheral pixels.

Abstract: A color image sensor has a first, second, and third color component pixels. The third color component pixel includes more intensity information than the first and second color component pixels. A difference estimating section estimates difference in a signal level exerted on a pixel signal of the third color component pixel, using the pixel signal of a pixel peripheral to the third color component pixel. A correcting section corrects the pixel signal of the third color component pixel on the basis of the estimated difference. Accordingly, when the third color component is green in a Bayer array, a pixel signal of a green pixel in a row of red pixels becomes equal to the pixel signal of a green pixel in a row of blue pixels. Therefore, line crawling can be suppressed without smoothing an image.

Abstract: An image is scaled by a desired scaling factor by using an upper scaling factor slightly greater than the desired scaling factor and a lower scaling factor slightly less than the desired scaling factor. The upper and lower scaling factors are applied to different parts of each horizontal or vertical line in the image. Both the upper and lower scaling factors are fractions with numerators and denominators less than the numerator and denominator of the desired scaling factor. The lower scaling factor may be obtained by decomposing the desired scaling factor into unit fractions. Regardless of the value of the desired scaling factor, the image can be scaled without the need for a large interpolation coefficient memory, and without resorting to iterated scaling and its attendant large data transfers.

Abstract: In each of stages of a nonlinear filter, a successively determined target signal and plural adjacent signals are weighted-averaged with plural sets of different coefficients to calculate plural smoothed signals. Differences in level between the target signal and each of adjacent signals and signals arranged within the predetermined interval from the each of the adjacent signals are compared with a threshold value. According to the comparison, flags are set to the adjacent signal, to an adjacent signal arranged at a symmetrical position, and to adjacent signals arranged beyond the adjacent signals. The intervals of adjacent signals are different among stages. The target signal in level is used instead of the adjacent signals with smoothed signals, which are selected according to the flags. Weighting coefficients may be calculated on the basis of the comparison result, and smoothed signals may be synthesized according to the weighting coefficients.
