Other Parameters

Other parameters needed by the 2A algorithm can use the following default values:

/* setting brightness target and range: range is always [target-threshold, target+threshold]. - numbers in 0~255 range
*/
p_ae_dynPrms->targetBrightnessRange.min = 40; /* lower bound of the target brightness range */
p_ae_dynPrms->targetBrightnessRange.max = 50; /* upper bound of the target brightness range */
p_ae_dynPrms->targetBrightness = 45;  /* target brightness */
p_ae_dynPrms->threshold = 5;  /* maximum change above or below the target brightness */
p_ae_dynPrms->enableBlc = 0;  /* not used */

/* setting exposure and gains */
p_ae_dynPrms->exposureTimeStepSize = 1;  /* step size of automatic adjustment for exposure time */
p_ae_dynPrms->digitalGainRange[count].min = 256;  /* digital gain not used */
p_ae_dynPrms->digitalGainRange[count].max = 256;  /* digital gain not used */
