Embodiment Construction

[0028] Compared with ordinary images, high-dynamic range (High-Dynamic Range, HDR) images can provide more dynamic range and image details to meet people's requirements for image quality.

[0029] In the prior art, the HDR image imaging solution is software multi-frame synthesis, which has poor real-time performance.

[0030] In the embodiment of the present invention, an image sensor is used for image acquisition, and the first image is acquired; the image sensor includes a plurality of pixel blocks arranged in a Bayer array, and the pixel blocks include four pixel blocks arranged in a 2×2 array. Pixels of the same color; combining the pixels of the same color in the pixel block in the first image to obtain a second image; mapping the bit depth of the second image to match the bit depth supported by the image processor to obtain a third image; performing image signal processing on the third image, and displaying the processed third image. The above solution, through hardware...

Abstract

The invention discloses an HDR image imaging method and device and a computer storage medium, and the method comprises: an image sensor carrying out the image collection, and obtaining a first image;wherein the image sensor comprises a plurality of pixel blocks which are arranged in a Bayer array, and each pixel block comprises four pixel points which are arranged in a 2 * 2 array and have the same color; merging the pixel points with the same color in the pixel blocks in the first image to obtain a second image; mapping the bit depth of the second image to be matched with the bit depth supported by an image processor to obtain a third image; and performing image signal processing on the third image, and displaying the processed third image. By adopting the scheme, the functions of previewing the HDR effect and recording the HDR video by a user in real time are realized while more dynamic ranges and image details can be provided for the shot image.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an HDR image imaging method, device and computer storage medium. Background technique [0002] Nowadays, people have higher and higher requirements on the imaging quality of image capturing devices. [0003] Compared with ordinary images, high-dynamic range (High-Dynamic Range, HDR) images can provide more dynamic range and image details to meet people's requirements for image quality. [0004] The HDR image imaging solution in the prior art is software multi-frame synthesis, which has poor real-time performance. Contents of the invention [0005] The technical problem solved by the present invention is poor real-time performance in the HDR image forming process. [0006] In order to solve the above-mentioned technical problems, an embodiment of the present invention provides an HDR image imaging method, including: acquiring a first image through an image sensor; the i...
