Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of image equipment, and particularly relates to an image system and a vehicle. BACKGROUND

[0002] In the related art, the function of the reversing image system of an automobile is relatively single. For example, in the daytime and at night, the current reversing light is only used as a supplement for reversing at night. However, this method is far from enough. It cannot meet the scenes such as large changes in brightness or strong light stimulation. For example, during the reversing process at night, a car appears behind, the initial light is relatively dark, the rear car turns on the high beam, the light gradually increases from far to near, and the reversing image is a glare, so that the situation of the rear car cannot be seen, which affects personal judgment and easily causes reversing safety hazards. SUMMARY

[0003] The present application aims to provide an image system and a vehicle, and at least solve one of the problems in the prior art that the reversing image system of an automobile cannot effectively image in a strong light scene, which easily causes reversing safety accidents.

[0004] To solve the above technical problems, the present application is implemented as follows:

[0005] In a first aspect, an image system is provided, which includes: a camera module, the camera module having an incident part; a light adjusting structure, located on one side of the camera module and corresponding to the incident part; a photosensitive sensor, located on one side of the camera module; and a control device, the camera module, the light adjusting structure and the photosensitive sensor being electrically connected to the control device, and the control device being capable of adjusting the light transmittance of the light adjusting structure according to the ambient light brightness of the photosensitive sensor.

[0006] In a second aspect, a vehicle is provided, which includes: the image system as in the first aspect.

[0007] In the embodiments of the present application, the image system includes a camera module, a light adjusting structure, a photosensitive sensor and a control device. The camera module has an incident part, the light adjusting structure is located on one side of the camera module, and the light adjusting structure is correspondingly arranged with the incident part of the camera module. That is, the light first passes through the light adjusting structure and then is transmitted to the incident part of the camera module.

[0008] The camera module, the light adjusting structure and the photosensitive sensor are all electrically connected to the control device, and the control device is capable of adjusting the light transmittance of the light adjusting structure according to the ambient light brightness of the photosensitive sensor. That is, the light transmittance of the light adjusting structure is adjustable, and the light transmittance of the light adjusting structure is related to the ambient light brightness of the photosensitive sensor. More precisely, the light transmittance of the light adjusting structure is related to the change of the light in the external environment.

[0009] Since the transmittance of the dimming structure can change according to the changes in the light in the environment, it is possible to adjust the amount of light entering the camera module according to the changes in the light in the environment, so that the imaging system will not produce glare even in a strong light environment. This setting can reduce the impact of the light in the environment on the imaging system, ensure the effectiveness and reliability of the imaging system, thereby ensuring the safety of the driver and improving the safety and reliability of product use.

[0023] The following combination Figures 1 to 4 The imaging system 100 and the vehicle 300 according to the embodiment of the present application are described.

[0024] like Figure 1 、 Figure 2 and Figure 3As shown, the imaging system 100 according to some embodiments of the present application includes: a camera module 110, the camera module 110 has an incident part 112; a dimming structure 140, located on one side of the camera module 110 and arranged corresponding to the incident part 112; a photosensitive sensor 150, located on one side of the camera module 110; a control device, the camera module 110, the dimming structure 140 and the photosensitive sensor 150 are all electrically connected to the control device, and the control device can adjust the transmittance of the dimming structure 140 according to the ambient light brightness of the photosensitive sensor 150.

[0025] In this embodiment, the imaging system 100 includes a camera module 110, a dimming structure 140, a photosensor 150, and a control device. The camera module 110 has an incident portion 112. The dimming structure 140 is located on one side of the camera module 110 and is disposed correspondingly to the incident portion 112 of the camera module 110. In other words, light first passes through the dimming structure 140 before being transmitted to the incident portion 112 of the camera module 110.

[0026] The camera module 110, the dimming structure 140, and the photosensor 150 are all electrically connected to a control device, which is capable of adjusting the transmittance of the dimming structure 140 based on the brightness of the ambient light of the photosensor 150. In other words, the transmittance of the dimming structure 140 is adjustable, and the transmittance of the dimming structure 140 is correlated with the brightness of the ambient light of the photosensor 150. More specifically, the transmittance of the dimming structure 140 is correlated with changes in the light in the external environment.

[0027] Since the transmittance of the dimming structure 140 can change according to the changes in the light in the environment, the amount of light entering the camera module 110 can be adjusted according to the changes in the light in the environment, so that the imaging system 100 will not produce glare even in a strong light environment. This setting can reduce the impact of the light in the environment on the imaging system 100, and can ensure the effectiveness and reliability of the imaging of the imaging system 100, thereby ensuring the safety of the driver and improving the safety and reliability of product use.

[0028] In some embodiments, as Figure 1 As shown, the dimming structure 140 includes a liquid crystal dimming plate 141 and a liquid crystal electrode 142 . The liquid crystal dimming plate 141 and the control device are both electrically connected to the liquid crystal electrode 142 .

[0029] In this embodiment, the dimming structure 140 includes a liquid crystal dimming plate 141 and a liquid crystal electrode 142 .

[0030] like Figure 1 As shown, the liquid crystal electrode 142 includes a positive electrode and a negative electrode, and an external voltage is applied through the liquid crystal electrode 142 to control the transparency of the liquid crystal dimming plate 141. The liquid crystal dimming plate 141 includes two polarizers.

[0031] Specifically, applying a voltage to the positive and negative electrodes shifts the polarization direction of the liquid crystal. Because the refractive index of the liquid crystal changes with the orientation of the liquid crystal, the polarization of light passing through the liquid crystal dimming plate 141 changes. By adjusting the relationship between the liquid crystal polarization direction and the electric field direction, the transmittance of the dimming structure 140 can be adjusted.

[0032] When the dimming structure 140 is opaque, for example, the dimming structure 140 may be black, ambient light cannot pass through the dimming structure 140 and propagate to the incident portion 112 of the camera module 110 .

[0033] When the dimming structure 140 is light-transmissive, for example, the dimming structure 140 may be white, ambient light can pass through the dimming structure 140 and propagate to the incident portion 112 of the camera module 110 .

[0034] When the dimming structure 140 is light-transmissive, the relationship between the polarization direction of the liquid crystal and the electric field direction can be adjusted to change the distribution state of the liquid crystal molecules of the liquid crystal dimming plate 141 to adjust the amount of light entering the incident part 112 of the camera module 110.

[0035] This configuration can achieve control of the amount of light entering the imaging system 100 through the rapid response of the liquid crystal of the dimming structure 140 to the alternation of light and dark.

[0036] In some embodiments, as Figure 3 As shown, the imaging system 100 further includes a pulse width modulation component 160. The control device and the dimming structure 140 are both electrically connected to the pulse width modulation component 160. The control device can adjust the duty cycle of the pulse width modulation component 160 according to the light intensity to adjust the transmittance of the dimming structure 140.

[0037] In this embodiment, the imaging system 100 further includes a pulse width modulation component 160 , which is connected between the control device and the dimming structure 140 . The pulse width modulation component 160 is electrically connected to the control device, and the pulse width modulation component 160 is electrically connected to the dimming structure 140 .

[0038] The control device can adjust the duty cycle of the pulse width modulation component 160 according to the light intensity. For example, in a strong light environment, the pulse width modulation component 160 starts to work and controls the amount of light entering the camera module 110 by adjusting the ratio of light transmittance and opaqueness of the dimming structure 140.

[0039] The dimming structure 140 has phase modulation capabilities. By energizing the liquid crystal electrodes 142, it can switch between two states (e.g., mode 0 and mode 1) between allowing light to pass through and not pass through at all. Furthermore, the addition of the pulse width modulation component 160 can ultimately achieve the goal of controlling the amount of light entering.

[0040] In some embodiments, the duty cycle of the pulse width modulation component 160 decreases as the light intensity increases.

[0041] In this embodiment, the duty cycle of the pulse width modulation component 160 and the change of the light intensity are further limited. Specifically, the duty cycle of the pulse width modulation component 160 decreases as the light intensity increases. That is, the duty cycle of the pulse width modulation component 160 can be specifically adjusted according to the light in the external environment to achieve the adjustment of the transmittance and opacity ratio of the dimming structure 140 according to the light intensity of the light, so as to achieve control of the amount of light entering.

[0042] In some embodiments, as Figure 3 As shown, the photosensor 150 includes a photosensitive diode, and the imaging system 100 also includes: a first power supply unit 170; a first relay 180, the photosensitive diode is connected between the first power supply unit 170 and the first relay 180, the pulse width modulation component 160 is connected between the first relay 180 and the dimming structure 140, and the first relay 180 is also electrically connected to the camera module 110; wherein, the photosensitive diode can be conductive along the direction from the first power supply unit 170 to the first relay 180.

[0043] In this embodiment, the photosensor 150 includes a photodiode, and the imaging system 100 further includes a first power supply 170 and a first relay 180. By properly configuring the coordination structure of the photodiode, the first power supply 170, and the first relay 180, the photodiode is connected between the first power supply 170 and the first relay 180, and the pulse width modulation component 160 is connected between the first relay 180 and the dimming structure 140.

[0044] Specifically, the first relay 180 is connected to the power line of the camera module 110 .

[0045] The photodiode conducts electricity from the first power supply unit 170 to the first relay 180. The positive pole of the power line connecting the first power supply unit 170 and the dimming structure 140 is normally off. When the photodiode detects strong light, it energizes the coil of the first relay 180, generating a magnetic field. This triggers a switch, closing the positive poles of the power supply lines of the first power supply unit 170 and the dimming structure 140, allowing the dimming structure 140 to operate. When the strong light near the imaging system 100 disappears, the coil of the first relay 180 de-energizes, and the positive poles of the power supply lines of the first power supply unit 170 and the dimming structure 140 return to their normally off state.

[0046] That is to say, when the photodiode is turned on, the duty cycle of the pulse width modulation component 160 decreases as the light intensity increases, so that the amount of light entering the camera module 110 changes continuously.

[0047] In some embodiments, the control device is further configured to obtain the ambient light brightness of the light sensor 150 at preset time intervals.

[0048] In this embodiment, the control device is further configured to obtain the ambient light brightness of the light sensor 150 at preset intervals. That is, at preset intervals, the control device adjusts the transmittance of the dimming structure 140 based on the ambient light brightness of the light sensor 150. In other words, at preset intervals, the transmittance of the dimming structure 140 is adjusted based on the ambient light in the external environment to achieve continuous control of the incoming light intensity, allowing the transmittance of the dimming structure 140 to vary in response to changes in ambient light. This configuration can reduce the impact of ambient light on the imaging system 100, thereby ensuring the effectiveness and reliability of the imaging system 100.

[0049] Specifically, the preset time includes 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, 9 seconds and 10 seconds, etc., which are not listed here one by one.

[0061] The display panel 190 controls the on and off of the dimming structure 140 via the power line of the first power supply unit 170 and the buses W2 , W3 , and W4 .

[0062] A photodiode is located on bus W4. When the photodiode senses strong light, the circuit is turned on, and the pulse width modulation component 160 adjusts the amount of light entering the camera module 110 according to a certain duty cycle. Normally, the W4 circuit is in a normally off state, and the transmittance of the dimming structure 140 is maximum.
