Title:
シーンを描写するビデオ画像ストリーム内の輝度変動を低減するための方法
Document Type and Number:
Japanese Patent JP6961664
Kind Code:
B2
Abstract:
The present invention relates to a method (20) and a digital video camera (30) for reducing intensity variations in a video stream depicting a scene. The method (20) comprises: capturing (S202), using a first sensor setting, a first frame (50); detecting (S204) a change in intensity in a portion (590) of the first frame (50), the portion (590) represents a first area of the scene; determining (S206) a second sensor setting based on the first frame (50); capturing (S208), using the second sensor setting, a second frame (60, 70); creating (S210) a local tone mapping mask, wherein a local tone mapping in the first area of the scene is different from a local tone mapping in an area outside the first area, and wherein the local tone mapping in the area outside the first area is based on a relation between the first sensor setting and the second sensor setting; and applying (S212) the local tone mapping mask to the second frame (60, 70).
