摘要： Fast channel changing in digital-television-based entertainment networks can be implemented, for example, by electing to tune to channels at opportune tuning times. In an exemplary implementation, a method includes: receiving a channel change request that indicates a requested new channel from a client device; preparing a broadcast video data stream of the requested new channel that is offset in time behind a current broadcast time for broadcast video data of the requested new channel; and streaming the broadcast video data stream responsive to the channel change request. In another exemplary implementation, a system includes: a storage device (408A) that retains broadcast video data (410) for multiple channels; a video data extractor (416) that accesses the retained broadcast video data and retrieves an intra frame of broadcast video data that is in the past for a requested channel; and a video data distributor (418) that transmits the retrieved intra frame of broadcast video data.

摘要： For accurately calibrating an inline scanner a printer such as an inkjet printer may print a pattern, which is scanned by the inline scanner. The method is configured such that print artifacts resulting from not yet calibrated print heads do not significantly influence the calibration of the scanner. After calibration of the scanner, the print heads and the control units driving the print heads may be calibrated using the calibrated inline scanner.

摘要： An original reading unit is provided that is superior in the performance of the adjustment of line sensors. According to the present invention, between a unit base and a transparent original support plate, multiple sensor assemblies are arranged, to form a zigzag pattern, as a first array for reading an original and a second array for reading the original following the first array. Each of the sensor assemblies includes a sensor holder, a line sensor and a focus setup unit. Each of the sensor holders, which serve as fulcrums, are rotatable at a single pivot (a rotation center), along the wall of a unit base that is parallel to the original support plate. When the sensor holders are rotated and positioned at predetermined locations, they are fixed to the wall. The line sensors 51 are held, relative to the sensor holders, in the main scanning direction and in the sub-scanning direction, and are moved in an approaching or separating direction in which the line sensors approach or are separated from the wall and the original support plate. The focus setup units, each of which includes coil springs and spacers, move the line sensors 51 in the approaching or separating direction, and position the line sensors 51 at locations whereat focuses are adjusted.

摘要： Interpolation data for a missing pixel are obtained (4) after a correction (3) for variations in the characteristics of the imaging devices (8(1), 8(2)). The correction for variations in characteristics includes, for example, a black level correction (9) and a sensitivity correction (10). The interpolation includes, for example, interpolation calculations (14(1), 14(2)) such that a mean value of a plurality of pixels including the missing pixel and a mean value of a plurality of pixels not including the missing pixel become equal and an interpolation calculation (14(0)) that takes the mean of the pixels to the right and left of the missing pixel, the calculation with the least error being selected (13, 15). Thus missing pixels in highly periodic images can be properly interpolated, and interpolation can be performed with high precision even when there are variations in the sensitivity characteristics of the individual imaging devices constituting the contact image sensor.
