摘要： The present disclosure discloses a method, device, electronic equipment and storage medium for generating a super night scene image. The method includes the following steps: acquiring consecutive multiple frames of original images, which include a frame of underexposed image and multiple frames of normally exposed images; performing stacked noise reduction processing on the multiple frames of normally exposed images to obtain a frame of normally noise-reduced image; performing gray scale transformation processing on the normally noise-reduced image to obtain a frame of overexposed image; fusing the underexposed image, the normally noise-reduced image and the overexposed image to obtain a frame of super night scene image.

摘要： Provided are an image fusion method and apparatus, and a portable terminal. The method comprises: obtaining several aligned images; respectively calculating gradient information of each image; setting a mask image of each image, and generating a target gradient image; performing a gradient operation on the target gradient image, and obtaining a target Laplacian image; performing a deconvolution transform on the Laplacian image, and generating a fused panoramic image. The technical solution generates a Laplacian image by performing gradient information calculations on several images, and then performs a deconvolution transform to generate a fused panoramic image, thereby eliminating image stitching color differences, and implementing a better image fusion effect.

摘要： The present invention provides a video decoding method and a camera. Said method comprises: loading a video, and decoding each frame from the video; calculating, for any two adjacent frames, a first optical flow field; calculating, according to the first optical flow field, a second optical flow field of a position where a frame is to be inserted, the position being located between two adjacent frames; using the second optical flow field to calculate a corresponding pixel position, in a previous frame of two adjacent frames, of each pixel of the frame to be inserted, and assigning the pixel value of the previous frame to the pixel of the frame to be inserted; and placing the inserted frame and the decoded original frame together according to a time sequence, so as to reconstitute a video having a high frame rate. The present invention eliminates or improves discrete motion, providing a more fluent viewing experience.

摘要： The present invention provides a motion ghost resistant HDR image generation method and a portable terminal. A normally exposed image and an underexposed image are mapped to an overexposed image and are fused in the overexposed image, such that the values of the underexposed image are more considered to be used in the fused image in a bright place and the values of the overexposed image are more considered to be used in a dark place; therefore, both the dark place and bright place have abundant information and a motion ghost resistant HDR image is finally generated, thus improving the visual effect of a ghost-removed high-dynamic range image.
