Abstract: A method, apparatus, and manufacture for generating an HDR image is provided. An original image is received from an HDR interlaced sensor that includes at least two fields captured with different exposures. The fields are separated from each other to provide separate images, and each of the separate images is upscaled. Next, blending is performed on each of the upscaled separate images to generate a high-dynamic range image, and ghost identification is performed on the high-dynamic range image. Subsequently, detail identification is performed on the high-dynamic range image. The detail identification includes identifying areas in the non-ghost areas of the high-dynamic range image that have details, and modifying the high-dynamic image by replacing each of the areas identified to have details with the corresponding area from the original image.

Abstract translation: 提供了一种用于生成HDR图像的方法，装置和制造。 从HDR隔行传感器接收原始图像，其包括用不同曝光捕获的至少两个场。 这些字段彼此分离以提供单独的图像，并且每个单独的图像被放大。 接下来，对每个放大的分离图像进行混合以产生高动态范围图像，并对高动态范围图像执行重影识别。 随后，在高动态范围图像上执行细节识别。 细节识别包括识别具有细节的高动态范围图像的非重影区域中的区域，以及通过将识别为具有与原始图像相对应的区域的细节的每个区域进行修改来修改高动态图像。
