A central feature of the DN100 network camera system main menu window is the button toolbar (illustrated in Figure 1), which provides convenient access to a number of the most commonly used camera control functions. The main menu can be accessed by right-clicking in the upper portion of the main image window during periods when no other menu is being displayed. Right-clicking the mouse inside of the displayed image window will close the main menu window, restoring the full-screen view of the displayed image.

The main menu toolbar provides access to three separate hardware configuration modes. When a setting for the active configuration is changed using a button on the main menu toolbar, the result will be reflected in the active configuration and in the displayed image. Clicking a button in the main toolbar menu will, in many cases, reveal additional controls. In these cases, the user should right-click the image window when finished with a setting change. Many of the buttons that appear in the pop-up controls are right- and left-click sensitive. Under most circumstances, left-clicking a button will decrease, and right-clicking a button will increase, the button's function value. The functions of the toolbar buttons are outlined as follows:

• Custom - Clicking this button allows the user to choose from among three different hardware configurations. Any changes made to the CCU settings will be stored in the active configuration.
• Mode - Repeated clicking of the Mode button toggles between exposure modes on the CCU. Each of the four available modes is described in the Exposure and Camera Sensitivity section. The settings of each of the four exposure modes from the main menu are summarized below:

• Program AE (program AE mode) - In this mode, the Comp setting icon (Figure 2) can be used to change the exposure compensation over a range from -2.0 EV to +2.0 EV in 0.3 EV steps.

• Speed AE (shutter speed priority AE mode) - The Speed icon (Figure 3) can be used to set the shutter speed between a range of 1/1000 second to 4 seconds. The Comp setting icon (Figure 3) can be used to change the exposure compensation over a range from -2.0 EV to +2.0 EV in 0.3 EV steps.

• Manual (manual exposure mode) - In manual mode, the Speed icon (Figure 4) can be used to set the shutter speed between a range of 1/1000 second to 60 seconds. The A_Gain icon (Figure 4) may then be used to set the camera gain over a range from x1 (A_Gain value of 100) to x46 (A_Gain value of 4600).

• F_AE (focus priority exposure mode) - In focus priority mode, the Comp setting icon (Figure 5) can be used to change the exposure compensation over a range from -2.0 EV to +2.0 EV in 0.3 EV steps.


• Gain - Clicking the Gain button (Figure 6) will reveal a pop-up adjustment bar that can be used to adjust output gain (brightness) of the digital image prior to capture.
• Wbset - Clicking the Wbset button toggles the white balance adjustment. White balance setting is described in the White Balance Calibration section.
• Tone - The Tone button controls the image tone or gamma. Five settings are available: 1. Low, 2. Mid, 3. High, 4. Linear, and 5. Enhance. A description of the tone controls and how they affect the appearance of the displayed image is discussed in the Image Correction Features section.
• Effect - Clicking this button will select a special effect for the displayed image. The five effect settings include Color, Nega, Blue Back, B & W, and Sepia. The results of these effects on the appearance of the displayed image is discussed in the Image Correction Features section.

• Color - The color balance control button allows the user to adjust RGB color-balance with a pop-up adjustment bar (Figure 7). There are two modes of color compensation available: Gain and Matrix, which can be selected by toggling the Gain/Matrix button (Figure 7). The effect of color-balance settings on the appearance of the displayed image is discussed in the Image Correction Features section.

• Sharpness - The sharpness control button has an adjustment bar (Figure 8) that can be used to toggle between six levels of image sharpness. Effects of the sharpness setting on the appearance of the displayed image is discussed in the Image Correction Features section.
• Fit/Over - This option changes the image screen display when the XGA display mode is selected.
• Change Pointer - Optional mouse pointers are available through this button, which allows the user to choose from among nine different mouse pointers. The wide variety of colored and shaped pointers is provided to ensure that the mouse pointer remains visible regardless of the color and texture of the background image.
• Save to Card - In order to capture the current image to the PC card, use the Save to Card button on the main image menu toolbar. The file will be saved using a filename that is chosen according to the file naming convention that is currently in effect.
• Save to Server - To avoid using the PC card and capture a digital image directly to the FTP server, use this button. The file will be saved using a filename that is chosen according to whatever file naming convention is in effect.
• SXGA/XGA - This button toggles between SXGA and XGA display modes. The default setting is SXGA.
• Setup - Clicking the Setup button will close the main menu window and automatically launch the setup menu.
