Embodiment 1

[0043] A high-quality image generation method, applied to the main controller, refer to figure 1 , the method includes:

[0044] S102. Obtain the light intensity value of the environment to be photographed detected by the light intensity sensor;

[0045] In the embodiment of the present invention, the method for generating a high-quality image is applied to a main controller, which may be a computer, MCU, CPU, etc., which is not specifically limited in the embodiment of the present invention.

[0046] Specifically, the main controller is connected to the light intensity sensor through a communication bus (such as USB, serial port, SPI, CAN, wireless network, etc.), and the light intensity sensor can detect the light intensity value of the environment to be photographed in real time, and compare the light intensity of the environment to be photographed Intensity values ​​are sent to the master controller without delay.

[0047] The light intensity sensor can fully cover commo...

Embodiment 2

[0077] A high-quality image generation device, applied to the main controller, refer to image 3 , the device consists of:

[0078] The first obtaining module 11 is used to obtain the light intensity value of the environment to be photographed detected by the light intensity sensor;

[0079] The matching module 12 is used to match the light intensity value of the environment to be photographed with the preset exposure time comparison table to obtain the secondary exposure time, wherein the preset exposure time comparison table is the corresponding relationship between the ambient light intensity and the exposure time Table, the secondary exposure time includes the highest exposure time and the lowest exposure time;

[0080] The determining module 13 is configured to determine a plurality of target exposure times based on the secondary exposure time and a preset exposure level, so that the image sensor can shoot the environment to be photographed according to the multiple targ...

Embodiment 3

[0092] An embodiment of the present invention provides an electronic device, referring to Figure 4 , the electronic device includes: a processor 30, a memory 31, a bus 32 and a communication interface 33, the processor 30, the communication interface 33 and the memory 31 are connected through the bus 32; the processor 30 is used to execute the executable module stored in the memory 31, For example a computer program. The processor implements the steps of the methods described in the method embodiments when the processor executes the program.

[0093] Wherein, the memory 31 may include a high-speed random access memory (RAM, Random Access Memory), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory. The communication connection between the system network element and at least one other network element is realized through at least one communication interface 33 (which may be wired or wireless), and the Internet, wide area network, ...

Abstract

The invention provides a method and apparatus for generating a high-quality image. The method comprises the following steps: obtaining an illumination intensity value of an environment to be photographed detected by an illumination intensity sensor; matching the illumination intensity value of the environment to be photographed with a preset exposure time comparison table to obtain a second levelexposure time; determining a plurality of target exposure times based on the second level exposure time and a preset exposure level, so that an image sensor photographs the environment to be photographed according to the plurality of target exposure times; obtaining a plurality of images photographed by the image sensor; and performing image synthesis on the plurality of images by using an HDR algorithm to obtain a high-quality image of the environment to be photographed. According to the method, only an illumination intensity sensor needs to be added on the basis of the original imaging system, so that the cost is low, the imaging process is simple and the calculation amount is small. The image synthesis is performed by using the HDR algorithm, so that the obtained final image has a goodeffect, and the technical problem that the cost and the imaging effect cannot be both considered in the existing method is alleviated.

Description

technical field [0001] The present invention relates to the technical field of image generation, in particular to a method and device for generating high-quality images. Background technique [0002] With the development of network informatization, the requirements for image and video imaging quality are getting higher and higher. The quality of image sensor imaging is not only related to sensor materials and 3A algorithms (AEC / AGC / ABC), but also to specific scenarios. It is related to the debugging of the next 3A algorithm. [0003] In conventional scenarios, the quality of camera sensor imaging depends on the control of the camera's automatic exposure (AEC) and automatic gain (AGC). Generally speaking, there are two methods for the existing cameras to achieve high-quality image shooting: one is that the image sensor realizes automatic exposure control, automatic gain control and white balance through a hardware image signal processor to improve the imaging performance of ...
