17、 sizes of the areas to be scanned. First, choose the job number (the numbers of the scan areas listed in the Job List) from the job number list box and then set the size of the scan area, click in the Scan Size list box. If you have set the original as Reflective (Flatbed) in the combo Boxes, you ca

18、n choose the scan area size from the list. Four frequently used formats are listed: A4, A5, B5 and Letter. You can also customize the scan sizes by choosing Custom in the list box and then enter the desired width and height into the Width and Height text boxes. The default unit is inch. To change th

19、e unit, press in the list box with your mouse, and choose the desired unit from the list by clicking it. If you have set the original as Transparent or Negative Film, the list box will contain only tow items: Max Area and Custom. Choosing Max Area, the full range of the image will be scanned. If you

20、 choose Custom, you can enter the sizes you want into the Width (max: 8 inches) and height (max: 10 inches) text boxes. After you complete your settings, click on the OK button to confirm you settings and close the dialog box. You can then press the c button to close the dialog box without saving yo

21、ur settings or you can press the apply button to apply your settings to the image without closing dialog box. 2) Monitor Gamma Generally, a monitor cannot display the real colors of an image in the real world. In order to have the monitor approximate the colors as possible, usually, you need to adju

22、st the monitor gamma. Adjustment of the monitor gamma can make the monitor approximate the colors of the original image more closely. Choose this item, and the following dialog box (Fig 17.5) will appear: Fig 17.5 Monitor Gamma dialog box From this dialog box, you can adjust the brightness in the mi

23、dtone of display so that it can approximate the color details of the original images. Drag the scroll bars to adjust the gamma values of red, green, blue and gray until the monitor displays the original colors more accurately. If the Syn box is checked, you can adjust all the four gamma values simul

24、taneously by dragging any scroll bar. When the adjustment is done, press the ok button to confirm your settings and close the dialog box; otherwise, press the Cancel button to cancel your settings and close this dialog box. If you use the default value, click on the Default button and MiraScan will

Timing From Microseconds to Hours Astable or Monostable Operation Adju

26、stable Duty Cycle TTL-Compatible Output Can Sink or Source up to 200 mA Designed To Be Interchangeable With Signetics NE555, SA555, and SE555 Description These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of oper

27、ation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-t

28、hirds and one-third, respectively, of UCC. These levels can be altered by use of the control-voltage terminal (CONT). When the trigger input (TRIG) falls below the trigger level, the flip-flop is set and the output goes high. If the trigger input is above the trigger level and the threshold input (T

29、HRES) is above the threshold level, the flip-flop is reset and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset and the output goes low. When the output is low, a low-impedance path is

30、 provided between discharge (DISCH) and ground (GND). The output circuit is capable of sinking or sourcing current up to 200 mA. Operation is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs. The NE555 (Fig 17.6) is characterized for operation fr

31、om 0 to 70. The SA555 is characterized for operation from 40 to 85. The SE555 is characterized for operation over the full military range of 55 to 125. Fig 17.6 the package of NE555 The package and definition of pins of NE555 are shown in Fig 17.6. （本文摘自某公司NE555芯片资料） 17.2.2 AD574A AD574 is a A/D con
