Problems solved by technology
[0003] Before the image sensor acquires image information, it must pass through the lens for imaging. Physically, since the lens is composed of various lenses, it is difficult to ensure that the focal points of each lens are located in the same plane during the use of the specific lens, so that The object to be photographed becomes curved after being imaged by the lens, that is, distortion occurs, causing the captured image of the object to become curved, and the greater the focusing factor of the lens, the more serious the imaging distortion, such as figure 1 shown

Embodiment Construction
[0039] As mentioned in the background art section, the image of the object captured in the prior art is curved, and the larger the focusing factor of the lens used for shooting, the more serious the imaging distortion.
[0040] In view of this, an embodiment of the present invention provides an image processing method applied to an electronic device, the electronic device includes a lens and an image sensor, and the image sensor is a flexible sensor for receiving an image collected by the lens for imaging , the method includes:
[0041] Obtain the imaging parameters when the lens captures the image;
[0042] Obtaining the distortion amount of the lens according to the imaging parameters when the lens collects the image;
[0043] According to the distortion amount of the lens, the curvature of the image sensor is adjusted to correct the image collected by the lens.
[0044] It can be seen that, when the image processing method provided by the embodiment of the present inventi...

The embodiment of the present invention discloses an image processing method, an image processing device, and an electronic device. The image processing method is applied to an electronic device, and the electronic device includes a lens and an image sensor, and the image sensor is a flexible sensor. , for receiving an image captured by the lens for imaging, the method includes: acquiring an imaging parameter when the lens captures an image; obtaining a distortion amount of the lens according to the imaging parameter when the lens captures an image; according to the The amount of distortion of the lens adjusts the curvature of the image sensor and corrects the image collected by the lens to improve the deformation of the collected image.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, an image processing device and an electronic device including the image processing device. Background technique [0002] Image quality processing is a variety of technical processing for various changes in image signals to achieve better image quality. At present, various processing technologies for image quality, including: image noise reduction, contrast enhancement, edge enhancement, etc., can all play a role in improving and enhancing the image quality. [0003] Before the image sensor acquires image information, it must pass through the lens for imaging. Physically, since the lens is composed of various lenses, it is difficult to ensure that the focal points of each lens are located in the same plane during the use of the specific lens, so that The object to be photographed becomes curved after being imaged by the lens, that is, ...
