  • Patent number: 7852377
    Abstract: 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.

  • Publication number: 20100149403
    Abstract: An image sensor system includes an image sensor that can be exposed with light from an illuminated scene to produce a secondary image, a meter sensor that can be exposed with light from the illuminated scene to produce a meter secondary image, and an image processor. The image processor can be configured to determine an average pixel color in the secondary image. The image processor can also be configured to determine a white balancing point in response to the secondary image average pixel color, the meter secondary image, meter calibration information for the meter sensor, and the image calibration information for the image sensor.

  • Patent number: 7668385
    Abstract: A method is provided for processing minimum coded units (MCUs) in a Joint Photographic Expert Group (JPEG) bit stream representing an image. A data structure is generated for storing MCU block numbers, corresponding MCU block coordinates, and corresponding MCU block editing lists. When an editing operation to the image is received, the editing operation is saved to a group of the MCU block editing lists of a group of the MCUs affected by the editing operation. Later the MCUs are retrieved from the JPEG bit stream one at a time and then processed according to the editing operations in the corresponding MCU blocking editing lists.

  • Publication number: 20090320225
    Abstract: A mechanical energy harvesting toothbrush may employ circuits and devices to convert mechanical energy into electrical energy. Such conversion can be done using piezoelectric devices to convert stresses and strains from bending of the toothbrush head and/or bristles during use, and can be done using electromagnetic generators involving passing a magnet through a coil to induce current. The resulting electric energy may be rectified, and stored in a storage device, such as a capacitor or rechargeable battery. A switching circuit may be configured to detect the level of energy stored in the storage device, and to close an electrical connection when a predetermined level of energy (e.g., a charge) has been reached. The predetermined level may correspond to a desired amount of brushing (e.g., taking into account stroke length and force, and the number of strokes), and the closing of the electrical connection may be used to power output devices when that desired amount of brushing has been reached.

  • Publication number: 20090268053
    Abstract: An image sensing system provides for accurate lens shading correction even when there is significant lens shading asymmetry and non-uniformity. A two-dimensional B-spline technique is used to determine lens shading correction surfaces. The number of zones is selected to achieve accurate correction of center, edge, and corner regions of an image. Separate lens shading correction surfaces are calculated for a set of standard illuminants to permit lens shading correction to be adapted based on the illuminant used to capture the image.
