Embodiment approach

[0078]1, the fixed first resolution and the second resolution multiple relationship, for example, the first resolution is always 4 times the second resolution, and only the appropriate second resolution is required when it is determined two resolutions. The calculation relationship of the current exposure parameter and the second resolution can be pre-configured according to the experience, and may be, for example, a linear ratio relationship. When the current exposure parameter is higher, the larger the second resolution, and then the second resolution is then calculated.

[0079]2, the calculation relationship of the current exposure parameter and the second resolution can also be pre-configured, and the first resolution is fixed to the maximum pixel of the image sensor. When actual shooting, according to the current exposure parameter, the second resolution is calculated, only the second distinguish Come.

[0080]3. Calculate the plurality of combined first resolution and second resolu...

Abstract

The invention provides an image fusion method, an image fusion device, a storage medium and terminal equipment, and relates to the technical field of image processing. The method is applied to terminal equipment with an image sensor, and comprises the steps of obtaining a first image and a second image collected by the image sensor, the first image being of a first resolution ratio, the second image being of a second resolution ratio, and the first resolution ratio being higher than the second resolution ratio; extracting an edge feature image from the first image; performing super-resolution reconstruction on the second image to obtain a third image with the same resolution as the first image; and fusing the edge feature image and the third image to obtain a final image. According to the invention, the problem of many noisy points of a high-pixel image can be solved, and the image shooting quality is improved.

Description

Technical field[0001]The present disclosure relates to the field of image processing, and more particularly to an image fusion method, an image fusion apparatus, a computer readable storage medium, and a terminal device.Background technique[0002]Image noise (or noise) refers to the image sensor or signal transmission circuitry, is generally generated by an image sensor or signal transmission circuit. At present, the pixels of increasing image sensors are the general development direction of the industry, such as image sensors that typically use millions or even thousands of pixels on mobile phones, which can support photos of ultra HD.[0003]However, as the pixel increases, the photosensitive area of ​​a single pixel on the image sensor is reduced, and the requirements for illumination are higher. For example, in a weak illumination environment, the photosensitive elements on the image sensor are more susceptible to crosstalk, resulting in less signal-to-noise ratio of the input sign...
