Input Channels The DT3120 board accepts one composite CVSB or one S video input source at a time Connect the composite input to connector J2 connector on the DT3120 board or connect the S video input to connector J 3 on the DT3120 board Principles of Operation Color Intensity Using software you can adjust the following settings of the DT3120 board to affect the intensity of the color Brightness The value associated with a pixel representing its gray value Values range from 0 to 255 in increments of 1 the nominal value is 128 Contrast The overall range of the monochrome signal of an image For example a high contrast image has a large range between black and white values a low contrast image has a small range between black and white values Values range from 0 to 511 in increments of 1 the nominal value is 216 e V Saturation The purity of the blue and green primary colors in an image For example if a particular pixel has a value of 0 for green but a value of 511 for blue then the pixel is said to be saturated in blue Values range from 0 to 511 in increments of 1 the nominal value is 180 e U Saturation The purity of the green and red primary colors in an image For example if a particular pixel has a value of 0 for green but a value of 511 for red then the pixel is said to be saturated in red Values range from 0 to 511 in increments of 1 the nominal value is 254 Hue The intensity

19. 16 Bit Data Format 21 Chapter 2 Passthru Operations In a passthru operation a DT3120 board continuously captures and displays video data until you stop the operation Typically you use passthru to view images in as close to real time as possible for the configuration and passthru method chosen for the purpose of focusing or positioning the camera In addition to displaying passthru data you can continuously store the data to user allocated buffers in host memory if desired This operation is called continuous acquire passthru mode This section describes the following aspects of passthru e Passthru modes Source origin e Passthru scaling and e Overlays Passthru Modes The DT3120 board supports bitmap passthru mode and continuous acquire passthru mode This section describes these modes Bitmap Passthru Mode The DT3120 board supports asynchronous bitmap passthru mode In an asynchronous operation the operation starts but gives control to you immediately allowing you to perform other operations while data is displayed Bitmap passthru mode requires a frame in device memory into which the image is captured 22 Principles of Operation Once the image is captured functions in Windows perform bit copies of the image data to display memory Functions in Windows handle obstructions to the passthru window by automatically clipping the passthru image to the visible client window region Therefore even
