    • The present invention provides an imaging apparatus which, when a dynamic range is expanded, even if a subject is irradiated by a plurality of different light sources, can apply adequate white balances to respective light sources. The imaging apparatus captures two images from an image sensor at different exposures when a preview image, which is input from the image sensor but is not captured yet, includes an area which is irradiated by the different light sources and which comprises the different brightnesses. The imaging apparatus then composes a dark area of the one image captured at the over exposure and applied a white balance to and a bright area of the other image captured at the under exposure and applied a white balance to.
    • 本发明提供了一种成像设备,当动态范围扩大时,即使被摄体被多个不同的光源照射,也可以向相应的光源施加足够的白平衡。 当从图像传感器输入但未被捕获的预览图像包括由不同光源照射并且包括不同亮度的区域时,成像设备从不同曝光的图像传感器捕获两个图像。 然后,成像装置构成在过度曝光时捕获的一个图像的暗区域,并将白平衡应用于在曝光下拍摄的另一图像的亮区域,并施加白平衡。
