Embodiment Construction

[0036] As mentioned in the background section, in the prior art, when high dynamic range imaging is implemented, it is difficult to strictly register images exposed at different time points during the shooting process, resulting in ghost images in the captured images, which affect the display effect of the images.

[0037] In view of this, an embodiment of the present invention provides an image processing device, which is applied to an electronic device, and the electronic device has an image generating device, and the image processing device includes:

[0038] a beam splitting unit, configured to split the beam image generated by the image generating device into at least two sub-beam images;

[0039] At least two image processing units, the image processing units are in one-to-one correspondence with the sub-beam images emitted by the spectroscopic unit, and are used to receive the corresponding sub-beam images and output them according to the preset exposure level. The prese...

Abstract

The embodiment of the present invention discloses an image processing device and an image processing method, which are applied to electronic equipment. The electronic equipment has an image generating device. The image processing device includes: a beam splitting unit, at least two image processing units, and an image synthesis unit. The unit is used to divide the beam image generated by the image generating device into at least two sub-beam images; the image processing unit is in one-to-one correspondence with the sub-beam images emitted by the beam splitting unit, and is used to receive the corresponding sub-beam images and output them according to the preset exposure level , different image processing units have different preset exposure levels; the image synthesis unit is used to synthesize the sub-beam images output by each image processing unit to obtain a final image. The image processing device can ensure that the exposure time points of each sub-beam image are the same, which solves the problem in the prior art that it is difficult to strictly register images exposed at different time points during the shooting process, resulting in ghost images in the captured image, and improves the image quality. display effect.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing device and an image processing method. Background technique [0002] High dynamic range imaging is the key performance of cameras and video cameras. Reasonable use of high dynamic range natural light to fully express the limited image brightness determines the imaging contrast and detail richness of the camera outdoors and in backlight. [0003] In the prior art, when realizing high dynamic range imaging, images of different exposure levels are usually recorded at continuous time points, and registration and fusion algorithms are used to fuse multiple images to obtain an image with better rendering effect. However, during the shooting process, it is difficult to strictly register images exposed at different time points, resulting in ghost images in the captured images, which affect the display effect of the images.
