Struct cameraunit::OptimumExposure

pub struct OptimumExposure { /* private fields */ }

Configuration used to find the optimum exposure.

Options

• percentile_pix - The percentile of the pixel values to use as the target pixel value, in fraction.
• pixel_tgt - The target pixel value, in fraction.
• pixel_tol - The uncertainty of the target pixel value, in fraction.
• pixel_exclusion - The number of pixels to exclude from the top of the image.
• min_exposure - The minimum allowed exposure time.
• max_exposure - The maximum allowed exposure time.
• max_bin - The maximum allowed binning.

Implementations

impl OptimumExposure

pub fn calculate( &self, img: Vec<u16>, exposure: Duration, bin: u8 ) -> Result<(Duration, u16), &'static str>

Find the optimum exposure time and binning to reach a target pixel value. The algorithm does not use any hysteresis and uses simple scaling.

Arguments

• mut img - The image luminance data as a vector of u16 that is consumed.
• exposure - The exposure duration used to obtain this image luminance data.
• bin - The binning used to obtain this image luminance data.

Returns

• Ok((Duration, u16)) - The optimum exposure time and binning.

Errors

• Errors are returned as static string slices.

pub fn get_builder(&self) -> OptimumExposureBuilder

Retrieve the builder for the [serialimage::OptimumExposure] calculator. This is useful for changing the configuration of the calculator.

Trait Implementations

impl Clone for OptimumExposure

fn clone(&self) -> OptimumExposure

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OptimumExposure

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for OptimumExposure

fn eq(&self, other: &OptimumExposure) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
