    摘要: Methods and apparatuses for color image restoration and enhancement. In at least one embodiment, color signals for individual channels of an image (e.g., red, green, or blue) are adjusted based on a weighted set of averages (e.g., of the entire image, the center portion, the surrounding portion, or other portions). In one example, pixels with extreme values of color signals (e.g., pure black or white pixels) are ignored for the purposes of restoring color; and, the different averages are weighted according to the pixel location (e.g., the distance from the pixel to a center point). In one example, after color restoration for individual channels, the luminance of each pixel is adjusted back to their original levels; and the range of luminance of the image is further adjusted to provide improved brightness and contrast, where in determining the luminance the red, green and blue color channels are given an equal weight.

    摘要: Deletion gestures for use on a portable multifunction device with a touch-sensitive display are disclosed. In some embodiments, a computer-implemented method for use in conjunction with the portable multifunction device comprises displaying a list of items on the touch-sensitive display, detecting a first gesture on the touch-sensitive display to edit the list of items, responding to the first gesture by displaying a first icon next to each deletable item in the list, detecting a second gesture on the touch-sensitive display to select one of the deletable items, and responding to the second gesture by displaying a second icon next to the selected item. If a third gesture on the second icon is detected, the selected deletable item is deleted. If a fourth gesture on the first icon next to the selected deletable item is detected, the second icon is deleted.
