Abstract

Embodiments of the present application provide an image scaling device, electronic equipment, an image scaling method, and an image processing chip, wherein the image scaling device is composed of a demosaic module and a scaling module, wherein the demosaic module is configured to separate Bayer format images It is a brightness channel image and a color channel image, and the size of the brightness channel image is greater than the size of the color channel image; the scaling module is configured to scale the brightness channel image and the color channel image according to the scaling ratio, and convert the scaled brightness channel image And the color channel image is merged into a Bayer format image. This application adopts a larger size scaling for the brightness channel sensitive to human eyes, and uses a smaller size scaling for the smoothly changing color channel, which can improve the scaling efficiency as much as possible under the premise of ensuring the quality of the scaled image.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image scaling device, electronic equipment, an image scaling method and an image processing chip. Background technique [0002] At present, the Bayer format image is widely used as a common image format in the image processing process of electronic devices such as smart phones and digital cameras. In order to improve the efficiency of image processing, electronic devices usually perform scaling processing on the original Bayer format image, for example, reducing the Bayer format image to half of the original size, so as to reduce the computational load of image processing. However, in the related art, the efficiency of scaling the image in the Bayer format is relatively low. Contents of the invention [0003] Embodiments of the present application provide an image scaling device, electronic equipment, an image scaling method, and an image processing c...
