Abstract:
(EN) Disclosed are an exposure method and apparatus, a computer system, and a movable device. The method comprises: determining, according to the luminance of a pixel of a first image and a luminance weight of the pixel, average luminance of the first image; determining, according to the average luminance of the first image, an exposure time corresponding to the first image, and desired average luminance of a second image, an exposure time corresponding to the second image. According to the technical solution in embodiments of the present invention, the exposure time can be effectively adjusted.
(FR) La présente invention concerne un procédé et un appareil d'exposition, un système informatique et un dispositif mobile. Le procédé consiste : à déterminer, en fonction de la luminance d'un pixel d'une première image et d'un poids de luminance du pixel, la luminance moyenne de la première image ; à déterminer, en fonction de la luminance moyenne de la première image, d'un temps d'exposition correspondant à la première image et de la luminance moyenne souhaitée d'une seconde image, un temps d'exposition correspondant à la seconde image. Selon la solution technique dans les modes de réalisation de la présente invention, le temps d'exposition peut être efficacement ajusté.
(ZH) 公开了一种曝光的方法、装置、计算机系统和可移动设备。该方法包括:根据第一图像的像素的亮度和该像素的亮度权重,确定该第一图像的平均亮度;根据该第一图像的平均亮度,该第一图像对应的曝光时间和第二图像的期望平均亮度,确定该第二图像对应的曝光时间。本发明实施例的技术方案,能够有效地调整曝光时间。
