Give weights to grids within an ROI In some scenes, like spotlight scenes, you may want to give weights to each grid within the ROI. To enable this feature, tune af_algo.reserve[96] and [97] . This feature can give weights based
Gravity-based FV weight feature. The BAF stats engine has vertical and horizontal kernel filter coefficients. In some chipsets, the filter coefficients are asymmetrical. For example, MSM8996 has a fourth order IIR filter for horizontal stats but a second order IIR
Fine-tune AWB initial tuning parameters About this task Use this procedure to update the initial AWB gain values after initial tuning. Procedure Click the AWB tab. To tune the initial gain and initial CCT parameters, do the following: From the
Fine-tune AWB reference points Before you begin Before performing any fine tuning, be sure to run the AWB auto-tune procedure to generate initial parameter values. About this task It is not recommended to do manual tuning for reference points because
Hand jitter processing consumes too much power The hand jitter process uses multiple gyro samples to correct the focus value based on the device motion. This can affect power consumption. If this occurs, tune haf.reserve[80] through [83] to set the
High dynamic range The scope of AEC for HDR is to determine two exposures: Long exposure, comprising long exposure time and long gains, and short exposure, comprising short exposure time and short gain. The ratio of long and short exposure
Histogram AEC luma target The tuning parameters for histogram AEC luma target adjustment are generic and not sensor dependent. They do not need to be retuned whenever a new sensor is enabled. Tuning is only required to fine-tune and match
History control AWB estimates the illuminant in a given scene based on several factors, including Bayer grid stats, scene brightness, and other information, and computes the AWB gain accordingly. Any changes in conditions, such as illuminant, brightness, and camera FOV,
History control parameters To view the history control parameters, open a project and click History Control in the List View tab. Table 1. History control tuning parameters Parameter name Description Tuning Factory default Tuning required Enable Flag Enables or disables
How the stable table and scene monitor tables work The min_stable_cnt parameter in the stable table works with the defocus_threshold and depth_stable_threshold parameters in the scene monitor table to determine if a scene change is stable. Scene stability is one
