48.5. Vignette Correction IP Software API

The IP includes software for run-time control. The IP does not fit any of the generic device models provided by the Nios II HAL and it exposes a set of dedicated accessors to the control and status registers. The IP driver structure inherits the base driver structure so all common methods defined in Video and Vision Processing IPs Software API are applicable.

Register definition header file: intel_vvp_vc_regs.h

Include file: intel_vvp_vc.h

instance - pointer to the intel_vvp_vc_instance software driver instance structure

Returns

the fraction of corrective gain for each vertical pixel step within the last mesh box

intel_vvp_vc_set_v_ramp_m1_frac

Prototype 
                    int intel_vvp_vc_set_v_ramp_m1_frac(intel_vvp_vc_instance* instance, uint32_t v_ramp_m1_frac);
Description

Writes the fraction of corrective gain for each vertical pixel step within the last mesh box. The instance must be a valid intel_vvp_vc_instance fully initialized.

Arguments

instance - pointer to the intel_vvp_vc_instance software driver instance structure

v_ramp_m1_frac - new fraction of corrective gain for each vertical pixel step within the last mesh box

Returns

kIntelVvpCoreOk (0) in case of success, a negative error code in case of an error

kIntelVvpCoreInstanceErr if the instance is a null pointer

kIntelVvpVcValueErr if the value of v_ramp_m1_frac is out of range

kIntelVvpVcCommitPendingErr if a previous commit request is pending

intel_vvp_vc_update_cp_lut

Prototype 
                    int intel_vvp_vc_update_cp_lut(intel_vvp_vc_instance* instance, uint8_t cp_lut_idx,
                    const uint32_t* cp_lut_values);
Description

Writes the color plane lookup table from a vector. The instance must be a valid intel_vvp_vc_instance fully initialized.

Arguments

instance - pointer to the intel_vvp_vc_instance software driver instance structure

cp_lut_idx - the color index of the lookup table to write to

cp_lut_values - pointer of a vector of lookup table values

Returns

kIntelVvpCoreOk (0) in case of success, a negative error code in case of an error

kIntelVvpCoreInstanceErr if the instance is a null pointer

kIntelVvpVcPointerErr if cp_lut_values is a null pointer

kIntelVvpVcParameterErr if cp_lut_idx is out of range

kIntelVvpVcLutNotAvailableErr if the lookup table is not available for this instance

intel_vvp_vc_update_step_lut

Prototype 
                    int intel_vvp_vc_update_step_lut(intel_vvp_vc_instance* instance, const uint32_t* step_lut_values);
Description

Writes the step lookup table from a vector. The instance must be a valid intel_vvp_vc_instance fully initialized.

Arguments

instance - pointer to the intel_vvp_vc_instance software driver instance structure

step_lut_values - pointer of a vector of lookup table values

Returns

kIntelVvpCoreOk (0) in case of success, a negative error code in case of an error

kIntelVvpCoreInstanceErr if the instance is a null pointer

kIntelVvpVcPointerErr if step_lut_values is a null pointer

kIntelVvpVcLutInvalidNumBlocksErr if the number of horizontal or vertical blocks were misconfigured to zero in a previous function call
