HDR image imaging method and device and electronic equipment

The invention provides an HDR image imaging method and device and electronic equipment. The method comprises the following steps: receiving an original raw sequence, and obtaining an exposure ratio; converting the original raw sequence by using the exposure ratio to obtain a raw sequence of the same exposure; carrying out weight calculation by utilizing the original raw sequence and the raw sequence with the same exposure to obtain a weight sequence; and enabling the weight sequence to act on the original raw sequence for image fusion, and generating an HDR image. According to the method, different exposure sequences in the raw field can be converted into the same exposure sequence in combination with the exposure ratio, the good linear relation of the raw field is beneficial to estimating the position of local motion, the accuracy of weight calculation is improved, and therefore the final calculation precision is improved. 本发明提供一种HDR图像成像方法、装置及电子设备。所述方法包括：接收原始raw序列，获取曝光比；利用所述曝光比对所述原始raw序列进行转换，获取相同曝光的raw序列；利用所
