20090207315 | IMAGE SIGNAL PROCESSING APPARATUS, IMAGE SIGNAL PROCESSING METHOD, AND PROGRAM - An image signal processing apparatus detects a motion vector between two temporally successive frames, and includes a detection device, a calculation device, and an arithmetic device. The detection device is configured to detect the motion vector in pixel blocks between the two frames, and output an evaluation value, which represents the degree of correspondence between the two frames in the pixel blocks provided in the two frames, and which is calculated in the process of detecting the motion vector. The calculation device is configured to calculate an activity value, which represents the degree of variation in pixel value in the frame, on the basis of the direction of the detected motion vector. The arithmetic device is configured to perform an arithmetic operation to obtain an accuracy value, which represents the degree of reliability of the detected motion vector, on the basis of the evaluation value and the activity value. | 08-20-2009 |

20150304657 | IMAGE PROCESSING DEVICE AND METHOD - An image processing device and method capable of suppressing block noise. A β LUT_input calculation unit and a clipping unit calculate β LUT_input that is a value input to an existing β generation unit and an extended β generation unit. When the value of β LUT_input qp from the clipping unit is equal to or less than 51, the existing β generation unit calculates β using the LUT defined in the HEVC method and supplies the calculated β to a filtering determination unit. When the value of β LUT_input qp from the clipping unit is larger than 51, the extended β generation unit calculates extended β and supplies the calculated β to the filtering determination unit. The device can be applied to an image processing device, for example. | 10-22-2015 |
