Abstract: A pixel array within an integrated-circuit image sensor is exposed to light representative of a scene during a first frame interval and then oversampled a first number of times within the first frame interval to generate a corresponding first number of frames of image data from which a first output image may be constructed. One or more of the first number of frames of image data are evaluated to determine whether a range of luminances in the scene warrants adjustment of an oversampling factor from the first number to a second number, if so, the oversampling factor is adjusted such that the pixel array is oversampled the second number of times within a second frame interval to generate a corresponding second number of frames of image data from which a second output image may be constructed.

Abstract translation: 集成电路图像传感器内的像素阵列在第一帧间隔期间暴露于表示场景的光，然后在第一帧间隔内对第一次数进行过采样，以生成对应的第一数量的图像数据帧， 可以构造第一输出图像。 对图像数据的第一数量帧中的一个或多个进行评估，以确定场景中的亮度范围是否需要将过采样因子从第一数量调整到第二数量，如果是，则调整过采样因子，使得 像素阵列在第二帧间隔内对第二次数进行过采样，以生成可以从其构造第二输出图像的图像数据的对应的第二数量帧。
