AXIS Q1765-LE Network Camera Video and Audio - Image overlays - Exposure zones - White balance windows - Action rules - Settings in uploaded applications Image Appearance Increasing the Color level increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a black and white image. The image Brightness can be adjusted in the range 0-100, where a higher value produces a brighter image. Increasing the Sharpness can increase bandwidth usage. A sharper image might increase image noise especially in low light conditions. A lower setting reduces image noise, but the whole image will appear less sharp. The Contrast changes the relative difference between light and dark. It can be adjusted using the slidebar. White Balance White balance is used to make colors in the image appear the same regardless of the color temperature of the light source. The Axis product can be set to automatically identify the light source and compensate for its color. Alternatively, select the type of light source from the drop-down list. For a description of each available setting, see the online help . The white balance window is enabled for the Automatic and Automatic outdoor options that appear in the White balance drop-down list. Select one of the options from the drop-down list to set the white balance window properties. Select Automatic to use the default settings for the Automatic and Automatic outdoor options (in the White balance drop-down list). Select Custom to manually set a reference window for white balance in the view area. Wide Dynamic Range Wide dynamic range (Dynamic Contrast) can improve the exposure when there is a considerable contrast between light and dark areas in the image. Enable WDR in intense backlight conditions. Disable WDR in low light conditions for optimal exposure. Note This setting is only possible when using automatic exposure control. Exposure Settings Configure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth considerations. Exposure value - Click in the bar to fine-tune the exposure. Exposure control - These settings is used to adapt to the amount of light used. Automatic is the default settings can be used in most situations. The shutter speed is automatically set to produce optimum image quality. Flicker-free 50 or 60 Hz is used to remove flicker which can be caused by fluorescent and other light sources. The Hold current option locks the current exposure settings. Enable Backlight compensation - Enable this option if a bright spot of light, for example a light bulb, causes other areas in the image to appear too dark. Exposure zones - This settings determines which part of the image is used to calculate the exposure. For most situations, the Auto setting can be used. For particular requirement, select a predefined area. 20
