A comparator is constructed to exclude an adverse effect of variation of a power source potential VDD or the like on a current output Iout. The comparator comprises a first voltage follower portion which receives an input potential Vin and outputs a potential (=Vin) following the input potential, a second voltage follower portion which receives a reference voltage Vref and outputs a potential (=Vref) following the input potential, and a current subtracting portion which outputs as a comparison result (Iout) a value achieved by subtracting the amount of current flowing due to the potential difference between the power source potential VDD of the comparator and the output potential (=Vref) of the second voltage follower portion from the amount of current flowing due to the potential difference between the power source potential VDD of the comparator and the output potential (=Vin) of the first voltage follower portion.

Characteristic amounts in each small region of audio signals transmitted in the working system and the standby system are extracted by characteristic amount calculators 6-1, 6-2. A characteristic amount comparator 7 compares the characteristic amounts and judges occurrence of a fault. Characteristic amount difference calculators 9-1, 9-2, ∥D∥ comparator 10, and faulty system judging unit 11 judges the system having a fault. Majority decision processor 12 and significance judging unit 13 enhance the reliability of the judgment. Delay difference of audio signals between systems is roughly detected by sub-sampling audio signals of two systems and comparing them, and then accurately detected without sub-sampling. Delay difference between audio signals is adjusted by the detected delay difference.

Received videos through A and B routes are inputted in first and second variable devices and then delayed by a first and a second frame memory by one frame to be inputted in a comparator. Alternatively, these signals A and B are further delayed by one frame by third and forth frame memories and also inputted in the comparator. The comparator compares the signals obtained by delaying the signals A, B, AF and BF by one line and one pixel, respectively, between the A and B routes with respect to all combinations so as to detect the difference between them. Then, a signal having the minimum difference is detected and a first and a second memory control signal to make the difference smaller are outputted to the first and second variable delay devices. By repeating the processing, a horizontal difference, a vertical difference and a time axial difference are gradually, and then completely, corrected including when the original amount of the difference is larger than a frame delay.

When a vehicle is traveling along a route toward a parking lot located near a destination facility, if traffic congestion along the route is detected, the navigation apparatus searches for an alternative parking lot that allows a user to reach the destination facility earlier than can by using the original parking lot. If such an alternative parking lot is detected, the predicted driving time and the predicted walking time are displayed together with a route to the parking lot. When traffic congestion is encountered when transporting a passenger by vehicle, the navigation apparatus determines a quicker way for the passenger to reach the destination facility. If the navigation apparatus detects that the passenger can reach the destination facility earlier if the passenger disembarks the vehicle and walks to the destination facility, the navigation apparatus presents information indicating a best point at which the passenger should disembark the vehicle.

A device for objectively evaluating the quality of a digitally transmitted picture. This device compresses encoded pictures x1 and x2 transmitted on two links that are decoded by a first decoder and a second decoder. A variance value &sgr;2(x1) of the decoded picture decoded by the first decoder is measured by a variance measuring unit. A variance value &sgr;2(x1−x2) of a signal indicative of a difference between the decoded pictures decoded by the first and the second decoders is measured. These two variance values are used to determine image quality.

There is provided an apparatus for displaying musical score data in a display area. In the apparatus, a specifying device specifies a display range of original musical score data. An extracting device extracts musical score data included in the display range from the original musical score data and extracts musical information precluded from the display range but influencing the extracted musical score data from the original musical score data. A determining device determines whether a supplementary display is necessary or not in accordance with the specified display range. A setting device divides the display area into a main display area and an auxiliary display area when the supplementary display is necessary. A display device displays the extracted musical score data in the main display area and concurrently displays the extracted musical information in the auxiliary display area. The display area may be divided into a plurality of display sub areas. A display format is specified for each of the display sub areas in accordance with setting of the division of the display area. The original musical score data is processed to generate musical score data compliant with the display format.
摘要:
Pressurized fuel of a common rail is introduced into a control chamber of a fuel injector. An electromagnetic valve opens or closes a fuel discharge passage of the control chamber to adjust a hydraulic pressure of the control chamber. Through a switching leak passage, bubble-containing fuel directly returns from a valve opening of the electromagnetic valve to a low-pressure return passage without passing through an armature chamber. Through a stationary leak passage, the fuel leaking from every slide portion returns to the return passage via the armature chamber. A downstream portion of the stationary leak passage opens to the upper portion of the armature chamber. A damper element is provided downstream of the electromagnetic valve in the return passage for canceling an increased fuel pressure.

On an initial screen, a conversion ratio indicated by a style conversion ratio data is displayed in a display area 32. Various kinds of styles are displayed in display areas 33 to 38. In this case, a style which is currently selected is "Samba" which blinks, and the conversion ratio is 50%. When a style number corresponding to samba is "2," a style change is conducted for the original performance data based on a style conversion data corresponding to the style number 2. At this time, the conversion ratio of 50% is referred, and changes of a sound-producing timing, a tone color, an additional instrument, and the like are conducted. An image displayed on a monitor is changed based on an image conversion data.

This invention provides a mode determination system for maximizing the coding efficiency by minimizing the amount of generated encoded information. An intra-frame picture signal X of 16 pels 16 lines is divided into four sub-blocks of 8 pels.times.8 lines by a DCT block dividing unit. A DCT block dispersion calculation unit calculates the dispersions of the four sub-blocks, and a nonlinear function transform unit transforms the dispersions to values for estimating amounts of generated encoded information. An adder unit adds together the four values for estimating amounts of generated encoded information and outputs the sum. On the other hand, a motion compensated predictive difference Y of 16 pels.times.16 lines undergoes a processing similar to said intra-frame picture signal X by a DCT block dividing unit, a DCT block dispersion calculation unit, a nonlinear function transform unit and an adder unit, and a value for estimating an amount of generated encoded information for the motion compensated predictive difference Y is outputted from the adder unit. An comparator unit outputs a signal for selecting a mode according to which of the two values for estimating amounts of generated encoded information is smaller.

When a selective decision of the field mode/frame mode for orthogonal transform is made for each macroblock composed of a plurality of blocks in a motion picture coding system wherein coding of an interlaced TV signal proceeds in the frame structure and an orthogonal transform is made in the unit of a block, the respective variances of the blocks within the macroblock are calculated, the calculated results are substituted respectively into an monotonously increasing and saturation tending nonlinear function to evaluate the sum of these functional values, and such a decision is made as to select the smaller mode in sum.
