    摘要: A method of implementing high dynamic range bin algorithm in an image sensor including a pixel array with a first super row having a first integration time and a second super row having a second integration time is described. The method starts by reading out image data from the first super row into a counter. Image data from the first super row is multiplied by a factor to obtain multiplied data. The factor is a ratio between the first and the second integration times. The multiplied data is then compared with a predetermined data. The image data from the second super row is readout into the counter. If the multiplied data is larger than the predetermined data, the multiplied data from the first super row is stored in the counter. If not, the image data from the second super row is stored. Other embodiments are also described.

    摘要: A method for simulating an image captured at a long exposure time (“simulated image”), includes (1) capturing each of first, second, and third images at a short exposure time, (2) determining a first relative motion between the first and the second images, (3) transforming the first image to remove the first relative motion, (4) determining a second relative motion between the third and the second images, (5) transforming the third image to remove the second relative motion, and (6) combining the first, the second, and the third images to form the simulated image. Relative motions between images are determined by matching blocks at multiple resolutions to determine corresponding points between the images. Transformation to remove relative motion is determined by fitting corresponding points between the images using a minimum square error (MSE) algorithm in a random sample consensus (RANSAC) framework.

    摘要: A method for removing a red eye from an image includes (1) calculating a weighted red value for each pixel in the image from red, green, and blue color values and a luminance value of each pixel in the image, (2) selecting a plurality of pixels in the image having weighted red values greater than a threshold as red eye pixels, and (3) correcting some of the red eye pixels to remove the red eye from the image. The weighted red value for a pixel is calculated as follows: f = c 1 ⁢ r + c 2 ⁢ g + c 3 ⁢ b Y , wherein f is the weighted red value, r is the red color value, g is the green color value, b is the blue color value, c1 is a first weight given to the red color value, c2 is a second weigh given to the green color value, c3 is a third weight given to the blue color value, and Y is the luminance.
