184.2 Camera Setup Menu ScreenSyncro Scan Is used to prevent black or white horizontal bars that may appear acrossyour computer monitor or television, when you are recording a scene that has either ofthese in it. By setting up the correct syncro scan in the menu, you can press the shutterbutton on the side of the camcorder and prevent this problem.What you are doing in the MENU, is trying to synchronize the camera’s shutter with thescan rate of the computer monitor or television included in the scene.Aspect Conversion Allows you to select the aspect ratio of the image to be recorded.The standard images have an aspect ratio of 4:3. When placed in 16:9 aspect ratio the im-ages are recorded with black bands across the top and bottom of the screen creating the16 by 9 or letter box image. This method is called letterbox and has the major advantage ofWYSIWYG (What You See Is What You Get). It you use an external anamorphic lensadaptor, about 25% higher vertical resolution can be obtained which may be more importantfor film out applications. If Letterbox is selected, the normal CCD based imager signal out-put of 720 pixels H by 480 pixels V is cropped down to 720 pixels H by 360 pixels V. Theremaining 60 pixels at the top and bottom of the picture are forced to black. When an exter-nal anmorphic lens is used the source image is optically converted from widescreen 16:9aspect down to a 12:9 aspect (4:3). Therefore the entire surface of the CCD based imagercan be used to capture the image, yielding a full 480 lines of vertical resolution.Color Bars A SMPTE test signal is generated internally, used to check the cameras per-formance, it also may be used at the beginning of the videotape as a reference.You can turn this function off or on in this menu. If you leave it on, it will shut off when thecamcorder is placed in the VCR mode or the power is shut off. This function does not workin the progressive mode.Setup Also called pedestal, this is the video black level in a video image, 0% isthe default setting for the DVX-100.
