For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0113] In addition, in the description of the application, it should be understood that the terms "width", "upper", "inner", "outer", etc. indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application. The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In the description of the application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise explicitly specified and limited.

[0114] The above is only the preferred embodiment of the application, and is not intended to limit the patent protection scope of the application. Any equivalent structural transformation using the content of the application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the application.

Claims

1. A detection apparatus, comprising: a biometric module configured to receive biometric information and detect the biometric information; and further configured to generate adjustment instructions based on the biometric information, and output the adjustment instructions to an electrochromic layer; a display optical module disposed between the biometric module and the electrochromic layer, and configured to display a three-dimensional image containing a preset picture effect; the display optical module is formed by a lenticular lens, so that the left eye and the right eye of a user receive different images; the electrochromic layer is configured to control a display state to switch between a transparent state and a non-transparent state in response to receiving a relevant electrical signal carried by the adjustment instructions, so as to expose or shield the three-dimensional image displayed by the display optical module; and further configured to output the biometric information to the biometric module in a case where the biometric information input by a user is collected. 2.The detection apparatus of claim 1, wherein the electrochromic layer is connected to an external control device. 3.The detection apparatus of claim 2, wherein the biometric module and the electrochromic layer are respectively connected to an external control device, the biometric module is further configured to output the adjustment instructions to the external control device, so that the external control device generates control instructions based on the adjustment instructions; the electrochromic layer is further configured to control the display state to switch between the transparent state and the non-transparent state in a case where the control instructions sent by the external control device are received. 4.The detection apparatus of claim 1, wherein the biometric module is further configured to detect the biometric information by capacitive sensing or optical recognition. 5.The detection apparatus of claim 1, wherein the electrochromic layer comprises an electrochromic material. 6.The detection apparatus of claim 1, wherein at least one light source is disposed inside the biometric module, and light emitted by the at least one light source transmits through the biometric module to irradiate the display optical module, so as to increase a light and shadow effect of the three-dimensional image output by the display optical module.

7. A detection method applied to a detection device, the detection device comprising: a biometric module, a display optical module and an electrochromic layer; the display optical module is disposed between the biometric module and the electrochromic layer, and the detection method comprises: receiving biometric information and detecting the biometric information by using the biometric module; generating adjustment instructions based on the biometric information by using the biometric module, and outputting the adjustment instructions to an electrochromic layer; displaying a three-dimensional image containing a preset picture effect by using the display optical module; the display optical module is formed by a lenticular lens, so that the left eye and the right eye of a user receive different images; controlling a display state to switch between a transparent state and a non-transparent state in response to receiving a relevant electrical signal carried by the adjustment instructions by using the electrochromic layer, so as to expose or shield the three-dimensional image displayed by the display optical module; and outputting the biometric information to the biometric module in a case where the biometric information input by a user is collected. 8.An electronic device, comprising a detection apparatus according to any one of claims 1 to 6, a processor and a communication bus.
