Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] In related technologies, when the intensity of the light signal in the environment where the image sensor is located is too high or too low to exceed the normal measurement range of the image sensor, the image sensor uses the amplifier to amplify the electrical signal by setting the gain of the amplifier, thereby expanding The working range of the image sensor avoids high-brightness blind areas or low-brightness blind areas in the image. However, this solution can only avoid the problem of high-brightness blind areas or low-brightness blind areas in the image to a certain extent, but there may also be local over-bright or over-dark problems in the image, resulting in poor image quality.

Abstract

The embodiment of the invention discloses an image generation method, device, terminal and storage medium, belonging to the technical field of computers. The method includes: acquiring an original image matrix according to the light signals collected by a plurality of photosensitive elements in the image sensor, the original image matrix includes image information output by the plurality of photosensitive elements, and obtaining a luminance component matrix according to the original image matrix, and the luminance component matrix is ​​used for Represents the luminance component contained in the image information output by multiple photosensitive elements. According to the luminance component matrix and the preset first convolution kernel, a second convolution kernel matching the original image matrix is ​​obtained. According to the second convolution kernel, the original The image matrix is ​​subjected to convolution processing, and an image is generated according to the processed image matrix. The signal detail components in the original image matrix are enhanced, the problem of local over-brightness or over-darkness in the image is effectively improved, and the quality of the generated image is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to an image generation method, device, terminal and storage medium. Background technique [0002] An image sensor is a component that converts optical signals into electrical signals. With the continuous advancement of technology and the rapid development of multimedia technology, image sensors are widely used in various types of terminals. The terminal can collect light through the configured image sensor. signal, and generate an image from the electrical signal converted from the optical signal. [0003] In related technologies, the image sensor has a working range that can normally measure the intensity of the light signal. When the signal strength of the light signal in the environment is too high or too low to exceed the working range, the image generated by the image sensor will have high brightness. Blind zone or low brightness blind zone. In...
