Detailed Description

template<uint8_t SourceBitDepth, uint8_t TargetBitDepth>
struct irsol::camera::PixelConversion< SourceBitDepth, TargetBitDepth >

Helper to convert pixel values from one bit depth to another with scaling.

This template computes a scaling factor at compile time to convert pixel values from SourceBitDepth to TargetBitDepth by linearly mapping the value ranges.

Example usage:

using SourcePixel = Pixel<12>;
using TargetPixel = Pixel<16>;
auto scaledValue = PixelConversion<12, 16>::scale(sourceValue);

Template Parameters

SourceBitDepth	Bit depth of the input pixel value.
TargetBitDepth	Bit depth of the output pixel value.

static Pixel< TargetBitDepth >::representation irsol::camera::PixelConversion< SourceBitDepth, TargetBitDepth >::scale ( typename Pixel< SourceBitDepth >::representation  value )

inlinestatic

Scales a pixel value from source bit depth to target bit depth.

Performs linear scaling of the input value and clamps the result to the maximum value allowed by the target bit depth.

Parameters

value

Pixel value at SourceBitDepth.

Returns

Scaled pixel value at TargetBitDepth.
