Basic Functions Exposure Compensation Exposure compensation is a function which offsets the internal reference brightness level used in the AE mode, by steps of 1.5 dB. Data 0E 0D 0C 0B 0A 09 08 07 06 05 04 03 02 01 00 Step 7 6 5 4 3 2 1 0 -1 -2 -3 -4 -5 -6 -7 Setting value 10.5 dB 9 dB 7.5 dB 6 dB 4.5 dB 3 dB 1.5 dB 0 dB -1.5 dB -3 dB -4.5 dB -6 dB -7.5 dB -9 dB -10.5 dB Slow AE (Automatic Exposure) The slow AE Response (automatic exposure) function allows you to reduce the exposure response speed. Usually the camera is set up so that the optimum exposure can be obtained automatically within about 1 second. However, using the slow AE response function allows you to lengthen the automatic exposure response speed from the factory setup speed (01 (hex) up to 32 times (20 (hex)). For example, with the normal setting (about 1 second), if the headlights of a car are caught by the camera, the camera automatically adjusts the exposure so that it can shoot a high-intensity subject (in this case, the headlights). As a result, images around the headlights, that is, the rest of the subject, except the headlights, becomes relatively dark, and poorly distinguished. However, using the slow AE function means the AE response speed will be slower, and response time will be longer. As a result, even if the camera catches a high-intensity subject (e.g., the headlights) for a moment, you can still easily distinguish the portions of the image surrounding the headlights. High Resolution Mode (Default) A newly developed DSP function enables the filtering of signals. This allows the camera to provide images with a high resolution (530 TV lines). When this function is set to OFF, the camera outputs images which are equivalent to 470 TV lines, just as with the FCB-EX480C/EX480CP camera. Aperture Control Aperture control is a function which adjusts the enhancement of the edges of objects in the picture. There are 16 levels of adjustment, starting from "no enhancement." When shooting text, this control may help by making them sharper. Back Light Compensation When the background of the subject is too bright, or when the subject is too dark due to shooting in the AE mode, back light compensation will make the subject appear clearer. Wide Dynamic Range Mode This function is effective when shooting images against the sun, or when shooting a very bright subject. Using a CCD with a wide dynamic range and a newly developed DSP allows the camera to combine signals shot at a normal shutter speed and high intensity images shot at the high shutter speed. The shutter speed automatically changes (1/1000 sec. to 1/8000 sec. Maximum ×128) depending on the level requested by high intensity images to obtain the best combined images. Note When the wide dynamic mode is ON, some part of the image may appear solarised. This is normal for the wide dynamic mode, and is not a camera malfunction. Slow shutter - Auto/Manual When set to "Auto," ensures that the slow shutter is set automatically when the brightness drops. Effective only when the AE mode is set to "Full Auto." Set to "Slow Shutter Manual" at shipment. ICR (IR Cut-Removable) Mode An infrared (IR) Cut-Filter can be disengaged from the image path for increased sensitivity in low light environments. The ICR will automatically engage depending on the ambient light, allowing the camera to be effective in day/night environments. When the auto ICR mode is set to ON, the image becomes black and white. 10
