摘要： A repositioner for a streaming magnetic tape drive apparatus includes control circuitry which, when a repositioning instruction is received from an external device, supplies a drive stop instruction to a tape reel motor and a measurement start instruction to a tape travel distance measuring device when a first data block edge detection signal is reproduced from the tape within a certain time period. A tape stop detection signal is produced when forward movement of the tape ceases, and the control circuitry outputs a reverse drive instruction to the reel motor while supplying a reverse tape travel distance measurement start instruction to the distance measuring device. When the forward and reverse tape travel distances become equal and a data block edge detection signal is reproduced from the tape within a certain time period, a normal operation signal is provided to the external device to signal that a repositioning operation is normally performed. Accordingly, adjacent data blocks on the tape will not be erased, and data read access will not be started midway along an adjacent data block on the tape.

摘要： A reel position-detecting device for use in a magnetic tape drive unit, designed to determine whether or not a supply reel has been positioned upside down in a retainer. When reel-detecting means detects that the supply reel has been set in the retainer, the retainer is rotated in the opposite direction to the tape-supply direction. If tape supply-detecting means detects the magnetic tape and then ceases to detect the tape within a predetermined period, processing means determines that the supply reel has been correctly positioned. Otherwise, the processing means determines that the supply reel has been positioned upside down.

摘要： An image processing device and image processing method that are capable of generating a stereoscopic image with limited system resources. Mask information defines a display region so that substantially the same number of pixels in first image data and second image data are displayed while the pixels are dispersed substantially uniformly. A mixer unit references the mask information and mixes the first image data with the second image data to generate output image data, which is a stereoscopic image.

摘要： The real number counter subtracts the positive integer C if the count value RC is equal to or larger than 0, or adds (the positive integer B-C) and outputs a Carry if the count value RC is negative. The first integer counter for generating the first clock f1 calculates (the count value IC1+the Carry+the positive integer A). The second integer counter 150 for generating the second clock f2 (f2=f1*G) calculates (the count value IC2+the Carry+the positive integer A+the offset value) at each input clock. The correction circuit outputs the offset value so that the second integer counter counts “the maximum count value*(f2/f1−1)*D” times more than the first integer counter with respect to each cycle D having a synchronization cycle length of the first clock f1 and the second clock f2.

摘要： The invention provides an edge detection circuit and a motion processing circuit which can prevent, upon motion detection between frames, erroneous detection at an edge portion, particularly a moving edge portion. A first edge detection section detects an edge of a pattern of an image provided by a first one of frames of a video signal and forwards a first edge detection signal. A second edge detection section detects the edge of the pattern of an image provided by a second one of the frames of the video signal at a time different from that of the first frame and forwards a second edge detection signal. An edge motion discrimination section receives the first and second edge detection signals and discriminates presence of absence of motion of the edge between the first and second frames based on the first and second edge detection signals. Consequently, any edge portion which exhibits motion between frames can be detected correctly.
