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.

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 approx. 10 minutes (30 (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 highintensity subject (e.g., the headlights) for a moment, you can still easily distinguish the portions of the image surrounding the headlights. High Resolution Mode This mode enhances edges and produces higher definition images. 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 (WD) The Wide Dynamic Range mode is a function for dividing an image into several blocks and correcting blocked-up shadows and blown-out highlights in accordance with the intensity difference. It enables you to obtain images in which portions ranging from dark to light can be recognized, even when capturing a subject with a large intensity difference that is backlit or includes extremely light portions. Images with wide dynamic range are produced by combining long-exposure signals (normal shutter) with the signals of the high-intensity portions obtained with a short exposure (high-speed shutter). Wide Dynamic Range Auto On/Off Mode The wide dynamic range can be set to be automatically switched ON/OFF in accordance with the intensity difference obtained by dividing an image into several blocks and then averaging the intensity of each block. Wide Dynamic Range Auto On/Off Mode Auto On/Off When the intensity difference between the dark portions and light portions of a subject becomes large because of back lighting or the like, the wide dynamic range mode is switched ON. When the subject changes and the intensity difference between the dark portions and light portions becomes small, the wide dynamic range mode is switched OFF. 10
