    • In embodiments, a camera device includes HDR monochromatic image sensors that capture an image as an HDR clear image in monochrome, and the camera device includes HDR color image sensors that capture the image as a Bayer image. The HDR monochromatic image sensors may be implemented as interlaced pixel lines having alternating higher exposure times and lower exposure times, or may be implemented as a checkerboard pixel pattern with white pixels of the checkerboard pixel pattern having an exposure duration and black pixels of the checkerboard pixel pattern having a different exposure duration. The camera device implements image processing algorithms that demosaic the Bayer image to generate an initial color image, and demosaic the HDR clear image to generate a clear image. An image fusion application then produces an enhanced, high-resolution HDR color image based on the initial color image and the clear image.
    • 在实施例中,相机装置包括以单色捕获图像作为HDR清晰图像的HDR单色图像传感器,并且相机装置包括将图像捕获为拜耳图像的HDR彩色图像传感器。 HDR单色图像传感器可以被实现为具有交替更高曝光时间和更低曝光时间的隔行像素线,或者可以被实现为具有曝光持续时间的棋盘像素图案的白色像素和棋盘像素的黑色像素的棋盘像素图案 图案具有不同的曝光持续时间。 相机设备实现图像处理算法,其对拜耳图像进行去马赛克生成初始彩色图像,并将HDR清晰图像拆分以产生清晰图像。 然后,图像融合应用基于初始彩色图像和清晰图像产生增强的高分辨率HDR彩色图像。
