ELECTRONIC CAMERA HAVING MULTIPLE SENSORS FOR CAPTURING HIGH DYNAMIC RANGE IMAGES AND RELATED METHODS

摘要

A camera has two distinct image sensor arrays. The image sensor arrays are at least one of different types and different resolutions. The image sensor arrays have different dynamic ranges such that one of the image sensor arrays is a high dynamic range image sensor array configured to capture a wider range of light intensity than the other of the image sensor arrays. The camera has an imaging mechanism configured to combine information collected by each of the image sensor arrays to produce a high dynamic range image. The image sensor arrays include one low resolution image sensor array having a high dynamic range, and one high resolution image sensor array having a normal dynamic range smaller than the high dynamic range wherein luminance values within the normal dynamic range represent a subset of luminance values within the high dynamic range.
