Member Data Documentation

struct rraew_colorpattern rraew_sensor::colorptn

Bayer pattern order.

There are different configuration of the RGB pixels in a Bayer pattern. It is important to set the correct one (given by the sensor) for satisfactory algorithm results

struct rraew_gain_step* rraew_sensor::gain_steps

Gain steps for the different ranges.

The array must be incrementally ordered, that means the lower range must be the firts element in the array.

RraewGetExposure rraew_sensor::get_exposure

Pointer to function that gets exposure time on the sensor.

void* rraew_sensor::get_exposure_target

Pointer to the instance that contains the get_exposure function.

For C applications this pointer can be NULL

RraewGetGain rraew_sensor::get_gain

Pointer to function that gets the sensor gain (before the statistics hardware)

void* rraew_sensor::get_gain_target

Pointer to the instance that contains the get_gain function.

For C applications this pointer can be NULL

int rraew_sensor::max_exp_time

Maximum exposure time.

Defines the maximun value that can be asigned to the exposure time.
Should be in the same units that the exposure time in the set/get exposure function

float rraew_sensor::max_gain

Maximum gain.

Defines the maximun value that can be asigned to the sensor gain, so it refers to the maximun value allowed by the set gain function
Use floating point NOT fixed point

int rraew_sensor::min_exp_time

Minimum exposure time.

Defines the minimun value that can be asigned to the exposure time.
Should be in the same units that the exposure time in the set/get exposure function

float rraew_sensor::min_gain

Minimum gain.

Defines the minimun value that can be asigned to the sensor gain, so it refers to the minimun value allowed by the set gain function. Use floating point NOT fixed point

int rraew_sensor::n_gain_steps

Number of gain ranges.

Usually the gain in a sensor can be divided in different ranges with different increment steps. For example the mt9p031 supports 3 ranges:

• 1-4 increments in steps of 0.125
• 4.25-8 increments in steps of 0.25
• 9-128 increments in steps of 1
  Here you define the number of available ranges, the steps for each range is defined with gain_steps

RraewSetExposure rraew_sensor::set_exposure

Pointer to function that sets exposure time on the sensor.

void* rraew_sensor::set_exposure_target

Pointer to the instance that contains the set_exposure function.

For C applications this pointer can be NULL

RraewSetGain rraew_sensor::set_gain

Pointer to function that sets the sensor gain (before the statistics hardware)

void* rraew_sensor::set_gain_target

Pointer to the instance that contains the set_gain function.

For C applications this pointer can be NULL
