The color changing member 11 is disposed on the open side of the cavity 163 and covers the lens 12, so that incident light passes through the color changing member 11 and then is imaged on the image sensor 13 through the lens 12. Also, the color changing member 11 includes a first transparent state having a first color as shown in fig. 3, and a second transparent state having a second color as shown in fig. 4.

With respect to the first and second colors of the color-changing member 11, it is noted that the first and second colors may alternatively be a single color. Or, the color group includes a plurality of colors arranged in a preset manner, and at this time, the colors of the first color and the second color are different or the arrangement manner of the colors is different, for example, the first color is a gradient color, and the second color is a heart-shaped pattern; or the first color is a red-based gradient color and the second color is a yellow-based gradient color. Alternatively, one of the first color and the second color is a single color and the other is a color group. Of course, the color change member 11 may also include transparent states having other colors, and there is no limitation on the number of transparent states that the color change member 11 can achieve. The embodiments of the present disclosure are described only by taking the first transparent state and the second transparent state as examples.

When the camera module 10 is started, the color changing member 11 is in a first transparent state or a second transparent state, and the lens 12 acquires an image and forms an image on the image sensor 13.

Therefore, when the color changing member 11 is in a shielding state, the third color is displayed at the light transmitting hole of the machine body. Specifically, when the color of the portion of the electronic device body surrounding the light-transmitting hole is set as the third color, the camera module 10 is turned off so that the color of the portion of the electronic device body surrounding the light-transmitting hole appears at the light-transmitting hole. Therefore, the difference between the light-transmitting hole of the machine body and other parts is weakened, and the machine body has an integrated and complete effect.

In one embodiment, the camera module 10 further includes a transparent cover 14 disposed on a side of the lens 12 opposite the image sensor 13, the transparent cover 14 covering the lens 12.

Optionally, the light emitting assembly 15 is a flash to improve the lighting conditions of the area being photographed when the image is acquired. At this time, the light emitting component 15 can achieve a colored flashing effect in cooperation with the first transparent state or the second transparent state of the color changing member 11. Or, the light emitting assembly 15 is a flashlight, and different lighting effects can be realized by the light emitting assembly 15 in cooperation with the shielding state of the color changing member 11. For example, the shielding state of the color-changing member 11 is semitransparent milky white, and the effect similar to ground glass is realized. At this time, the light emitting effect of the light emitting component 15 is soft, and the situation that strong light is dazzled when the light emitting component 15 is started in a dark environment is avoided.
