    摘要: A method of implementing a fast video encoder by approximating a frame motion vector is introduced. MPEG-2 encoding uses both field and frame vectors in the encoding process. To implement an encoder in an efficient manner, an approximated motion vector created from two field motion vectors is used. The frame motion vector may be determined using the two field motion vectors alone, or by using the two field motion vectors in conjunction with their respective absolute error values. By using the disclosed methods, a motion estimation part for generating frame motion vector is not necessary. Only two field motion estimation parts are required to determine the field motion vectors, the frame motion vector is then approximated using the two field motion vectors. The cost and complexity of a digital video encoder system is thereby reduced.

    摘要: The invention provides a paper feed control device having paper feed rollers for feeding a paper sheet such as an original to a predetermined position, a first sensor for detecting the paper sheet, a second sensor for detecting leading and trailing ends of the paper sheet, a microcomputer for controlling the rollers in response to the outputs signals from the sensors, and a compensating circuit for compensating the level of the output signal from the second sensor which is maintained in a non-detecting state until the paper sheet completely passes through the second sensor. Therefore, even if punched holes for filing are formed on the paper sheet, the punched hole may not be detected as the trailing end of the paper sheet, resulting in proper feeding.
