摘要： A method corrects trapezoid distortion of projected images using a projector. The projector includes a projection lens, a driver device, an image capturing device, and a storage system. A rectangular picture is read from the storage system and projected on a projection area by the projection lens. The method controls the image capturing device to capture an image from the projection area when the projection lens increases one trapezoid row correction grade, and corrects each trapezoid row of the captured image if the captured image has trapezoid rows. The method further controls the image capturing device to capture an image from the projection area when the projection lens increases one trapezoid column correction grade, and corrects each trapezoid column of the captured image if the captured image has trapezoid columns.

摘要： A method for automatically focusing a projector includes a projection lens, a driver device and an image capturing device. The method sets an interval step according to a focusing range of the projection lens, reads a predefined picture from a storage system of the projector, and controls the projection lens to project the picture to a projection area. The method controls the image capturing device to capture an image of the picture from the projection area when the projection lens moves at every interval step, and analyzes a contrast of each of the images to determine an optimal image from the images. The method determines a current focus of the projection lens having the optimal image as an optimal focus of the projection lens, and drives the driver device to control the projection lens to move at the optimal focus.

摘要： A method captures images of objects using an image capturing apparatus. The method obtains x-coordinate values, y-coordinate values, and z-coordinate values of the accelerations of a camera device sensed by a gravity sensor in a default time interval, calculates three-dimensional coordinate differences according to the obtained x-coordinate, y-coordinate, and z-coordinate values, and determines whether the three-dimensional coordinate differences are less than corresponding predefined thresholds. If at least one coordinate difference is not less than a corresponding predefined threshold, the method delays a period of time to obtain the x-coordinate, y-coordinate, and the z-coordinate values in a next default time interval. If all the three-dimensional coordinate differences are less than the corresponding predefined thresholds, the method controls the camera device to capture images of the subject object.

摘要： A computing device and a method for controlling access to driver programs obtains a first system time at the time that an application uses a CTL_CODE to access a driver program. The first system time and the CTL_CODE is encrypted to generate an encrypted CTL_CODE which is then sent to the driver program. The encrypted CTL_CODE is decrypted to obtain the first system time and the CTL_CODE therein. A second system time at the time that the driver program receives the encrypted CTL_CODE is obtained and compared with the first system time. Access to the driver program is allowed if a difference between the first system time and the second system time falls within a predetermined range, and access to the driver program is forbidden if the difference is beyond the predetermined range.

摘要： In a method for marking discrepancies of a captured image of an object, an image is captured and compared to a standard image. A discrepant image showing any discrepancies of the captured image is generated, and is separated into an R grayscale image, a G grayscale image, and a B grayscale image. An R channel matrix group, a G channel matrix group, and a B channel matrix group are created. R channel negative matrixes, G channel negative matrixes, and B channel negative matrixes are determined from the RGB channel matrix groups. RGB pixel groups are calculated based on the R channel negative matrixes, the G channel negative matrixes, and the B channel negative matrixes. A target pixel group to be marked is determined by calculating an intersection of the RGB pixel groups. The discrepancies of the digital image are marked out according to the target pixel group.

摘要： In a method for identifying discrepancy of a captured digital image of an object, a standard image of the object is obtained. A first difference value between an IAED value of the digital image and an IAED value of the standard image is calculated. Both the two images are divided into N pixel blocks. A second difference value between an IAED value of each pixel block of the digital image and an IAED value of each pixel block of the standard image is calculated. A coefficient T is generated for comparing the digital image and the standard image, and each block of the digital image is compared with each pixel block of the standard image. The same pixel blocks between the digital image and the standard image are eliminated from the digital image, and a discrepant image is generated according to remaining pixel blocks of the digital image.
