    摘要： 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.

    摘要： A method and apparatus for correcting for vignetting include associating each pixel in the two-dimensional array with a pair of polar coordinates referenced to a preselected origin pixel and partitioning the two-dimensional array of image pixels into a plurality of sectors. For each sector, the method includes computing an average R value, an average G value and an average B value; converting the average R value, the average G value and the average B value for each sector to logarithm space; comparing color gradients along a radial sector line to a gradient threshold; selecting gradients that do not exceed the threshold; using the selected gradients, estimating parameters of a model of a lens which produced the image; and, using the parameters, updating the model of the lens and correcting the image.

    摘要： 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. The closing of the electrical connection may be used to power output devices when that desired amount of brushing has been reached.
