Fig. 1 is a schematic structural diagram of a camera module 100 according to an exemplary embodiment. As shown in fig. 1, the camera module 100 may include a camera module 1, a flash module 2, a light sensor 3, and a circuit board 4, the circuit board 4 is connected to both the camera module 1 and the light sensor 3, and the circuit board may be connected to a main board of an electrical device in which the camera module 100 is configured, so as to control a switching state of the camera module 100, and to acquire and display an image taken by the camera module 1.

Wherein, this camera module 1 can be used for acquireing the image, and when electronic equipment's external brightness was not enough, flash light module 2 can carry out the light filling to promote the effect of the image that camera module 1 acquireed. The flash module 2 may include a light source (not shown) and a flash lens 21, and the flash lens 21 is closer to the outer surface of the camera module 100 than the light source, so as to protect the light source through the flash lens 21, and the light source 21 may be an LED light source, which may perform blanking for an object to be photographed in a dark environment.

The light sensor 3 is located below the flash lens 21, the light sensor 3 may be configured to obtain light source fluctuation information of an external light source, the light source fluctuation information may include constant light source information and periodically changing light source information, and the periodically changing light source information may be configured to perform image processing on an image obtained by the camera module 1, so as to equalize brightness at each position on the image.

For example, when the camera module 100 is used to capture a picture shown by a display, the external light source may include ambient light and light emitted by an LED element or an OLED element in the display, and it can be understood that both the LED element and the OLED element are refreshed and scanned at a certain frequency to realize picture display.

Further, when the camera module 100 is shooting a display screen, due to a difference between the exposure time of the camera module 1 and the refresh frequency of the LED module or the OLED module in the display, there may exist some rows of pixels that are not lighted in all rows of pixels on the display at a single shutter speed, so that the image obtained by the camera module 1 has stripes with alternate light and shade, and the image effect is not good. And through this disclosed technical scheme, can set up light sensor 3 and determine light source constant information and light source change information, can confirm the frequency of the light source that produces this light source change information through this light source change information, can determine corresponding luminance through fast Fourier change algorithm according to this frequency, follow-up can subtract the luminance that changes the light source information and correspond on the luminance basis that the camera module was confirmed at the same moment, realize the image processing to the image, the luminance of each position on the balanced image, avoid appearing the stripe of alternate light and shade, promote the effect of shooing. The frequency of the variable light source information may be 50Hz or 60Hz, or may also be 80Hz, and the like, which is not limited in this disclosure.

In this embodiment, the flash module 2 may further include a fresnel lens 22 and a diffusion sheet 23, the fresnel lens 22 is located between the light sensor 3 and the flash lens 21, and the fresnel lens 22 may include a fresnel texture 221 formed on a surface of the fresnel lens 22 disposed toward the light sensor 3. Therefore, the internal electronic components can be shielded by the fresnel texture 221 on the fresnel lens 22, and the visual effect can be improved.

Since the fresnel lens 22 is provided with the uneven fresnel texture 221, the detection of the light incident from various angles by the light sensor 3 is affected, and the processing effect of the image processing is affected. Therefore, in the technical solution of the present disclosure, a diffusion sheet 23 is further provided, the diffusion sheet 23 may be located between the fresnel lens 22 and the light sensor 3, and the light emitted from the fresnel lens 22 may be softened by the diffusion sheet 23, so that the light can be uniformly received by the light sensor 3.

Specifically, the response of the light ray sensor 3 to each angle light ray substantially satisfies a cosine response curve as shown in fig. 2, where the abscissa is an angle β between the incident light ray and the light ray receiving surface S1 of the light ray sensor 3, and the ordinate is S1 × cos β/S1. As shown in fig. 3, a curve L1 is a response curve of an incident light ray directly incident on the light sensor 3 from various angles, a curve L2 is a response curve of an incident light ray directly incident on the light sensor 3 from various angles after passing through the fresnel lens 22, which has deviated from a theoretical response curve of the light sensor 3, and a curve L3 is a response curve of an incident light ray directly incident on the light sensor 3 from various angles after passing through the fresnel lens 22 and the diffusion sheet 3, which is substantially similar to the curve L1 and satisfies a theoretical response of the light sensor 3 to an incident angle. The thickness of the diffusion sheet 3 may be in a range of 50um-120um, such as 60um, 80um, 100um, etc., in order to satisfy the theoretical response curve of the light exiting the sensor 3 as much as possible, which is not limited by the disclosure.

In another embodiment, as shown in fig. 4, the fresnel lens 23 may also include ink particles 222 located inside the fresnel lens, and the ink particles 222 may diffuse the light, so that the light in each direction can substantially satisfy the theoretical response condition of the light sensor 3 when being incident to the light sensor 3 through the fresnel lens 22, thereby improving the detection accuracy.

Based on the above embodiments, the present disclosure may further provide an electronic device 200 as shown in fig. 5, where the electronic device 200 may include the camera module 100 described in any of the above embodiments. The electronic device 200 may include a mobile phone terminal or a tablet terminal, which is not limited in this disclosure.

Based on the technical scheme of the present disclosure, an image processing method is also provided, which can be applied to an electronic device, where the electronic device includes a camera module, the camera module includes a camera module, and the camera module is used to obtain an image information image; a flash module comprising a flash lens; a light sensor located below the flash lens.

Therefore, the light source fluctuation information may include a constant light source information and a periodically varying light source information.

Further, the electronic device 200 may further comprise a light sensor, which may be used to determine the frequency of the varying light source information, which may further be sent to a processor of the electronic device. For example, assuming that the light source information is changed to be the display light source, the display is usually powered by the power supply with a certain frequency in a sine wave shape as shown in fig. 7, so that when the power supply is changed, the light emitted by the display light source also changes in a sine wave shape, and since the power signal has positive and negative portions and the light has no positive and negative portions, the frequency of the light emitted by the display light source is twice as high as the frequency of the power supply as shown in fig. 8. For example, if the frequency of the power supply signal is 50Hz, the frequency of the changed light source information is 100Hz, and if the frequency of the power supply signal is 60Hz, the frequency of the changed light source information is 120 Hz.

In step 602, image processing is performed on the image acquired by the camera module according to the changed light source information, so as to equalize brightness of the image.

In this embodiment, the processor may determine the brightness corresponding to each time through the fast fourier transform algorithm and the frequency of the changed light source information, and the camera module may also obtain the brightness at each time when acquiring the image information, so that, under the same timestamp, the brightness of the changed light information is subtracted from the brightness acquired by the camera module, and the processing of the image acquired by the camera module and the brightness of the image are equalized.
