A color filter array includes color filter units each of which is a square array formed by four square pixels. The first color pixel and the second color pixel are arranged to form a row, the two third color pixels are arranged to form another row, and a row pixel direction of the color filter unit relative to a horizontal direction is inclined by 45&#xb0; to left or right. The color filter array is an inclined rectangular array, pixels from an intermediate row to a first row or to a last row in a same direction is progressively decreased with a decrement of 1 or 2, and pixels in the first row and the last row is 1 or 2. The application can significantly increase the area of pixels of the unit color filter, and improve the sensitivity of the image sensor without reducing the resolution of the image sensor.

A pixel array is provided. The pixel array comprises a plurality of two-dimensionally arranged 4*4 Bayer matrix units, in which the matrix unit comprises a plurality of pixels, any of a green filter, a red filter and a blue filter is disposed in one pixel, and one or more of the green filters are replaced by white color filters in the matrix units. A camera using the same and a color processing method based on the pixel array are also provided.

A method of image edge enhancement comprises: determining the edge trend for an image in accordance with the second order gradient value of a center pixel in different directions; performing interpolation operation with the center pixel; calculating absent color component of pixels; performing edge enhancement for the image in the interpolation module in accordance with original color component of the center pixel and the image edge trend based on the Bayer data. The image edge enhancement process takes into account the influence of the green component values of different pixels surrounding the center pixel, and adopts a noise-resistant, self-adaptive edge enhancement algorithm, to suppress noise on the image edge. Thus, the resulting image has a clear image edge. In addition, the fact that the process performs image edge enhancement in the interpolation module based on the Bayer data can significantly reduce the consumption of memory space.
