sceneAdjustLuminance

PURPOSE

Scale scene mean luminance to meanL

SYNOPSIS

function scene = sceneAdjustLuminance(scene,meanL)

DESCRIPTION

Scale scene mean luminance to meanL

  scene = sceneAdjustLuminance(scene,meanL)

 The photon level in the scene structure is multiplied so that the  mean
 luminance level is meanL, rather than the current level.   The fields
 scene.data.luminance and scene.data.meanL are updated as well. 

Example:

 scene = vcGetObject('scene');
 scene = sceneAdjustLuminance(scene,100);  % Set to 100 cd/m2.
