A | Page 18 of 28 ADAPTIVE CONTRAST ENHANCEMENT (ACE) The ADV7280/ADV7280-M can increase the contrast of an image depending on the content of the picture, allowing bright areas to be made brighter and dark areas to be made darker. The optional ACE feature enables the contrast within dark areas to be increased without significantly affecting the bright areas. The ACE feature is particularly useful in automotive applications, where it can be important to discern objects in shaded areas. The ACE function is disabled by default. To enable the ACE function, execute the register writes shown in Table 13. To disable the ACE function, execute the register writes shown in Table 14. Table 13.
