Problems solved by technology

[0004] However, Figure 1A In the structure of , since optical elements such as the reflective element 101 and the lens 105 are required, the overall volume cannot be reduced
In addition, due to the long optical path of the optical signal and the processing of reflection and penetration, it will affect the imaging of the fingerprint, resulting in inconspicuous contrast.
Moreover, such a structure is also easy to make the image of the finger interfered by the ambient light

Embodiment Construction

[0033] Certain terms are used in the specification and following claims to refer to particular elements. It should be understood by those skilled in the art that hardware manufacturers may use different terms to refer to the same element. The description and the preceding claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The term "comprising" mentioned throughout the specification and the preceding claims is an open-ended term, so it should be interpreted as "including but not limited to". Figure 2 to Figure 5 An image capturing device according to the present invention is shown. exist figure 2 Among them, the image capture device 200 includes a light source 201 and a sensor 203 . The surroundings of the sensor 203 can be protected by a protective material 205 such as epoxy resin (epoxy), but not limited thereto. The light source 201 makes the incident light EL ...

Abstract

The invention discloses an image acquisition device. The image acquisition device comprises a light source and a sensor. According to the light source, incident light does not pass through media except air, enters a target object directly and exits from the target object, so that transmitting light is generated. The sensor is used for acquiring the image of the target object according to the transmitting light.

Description

technical field [0001] The present invention relates to an image capture device and an optical displacement estimation device using the image capture device, in particular to an image in which incident light generated by a light source is directly injected into an object without passing through a medium other than air A capture device and an optical displacement estimation device using the image capture device. Background technique [0002] With the continuous advancement of technology, touch devices using mechanical or resistive or capacitive touch devices in the past are gradually replaced by optical touch devices. This type of optical touch device can be regarded as an optical displacement estimation device, because the relative motion between the sensing surface of the device and an object (such as a finger) is judged. [0003] This type of optical displacement estimating device usually has an image capture device to capture image frames of the target object produced at...
