Abstract:
A fingerprint scanning device and an electronic device with a fingerprint scanning function are proposed. The fingerprint scanning device has a contact image sensing module, a signal conversion controller, a module controller and an interface controller. The contact image sensing module captures a fingerprint image. The signal conversion controller converts this analog fingerprint image to a digital signal. The module controller controls the contact image sensing module and the signal conversion module. The interface controller transmits the digital signal to a controller in an electronic device. The contact image sensing module is used to lower the cost and lengthen the lifetime of use of the fingerprint scanning device, and to make the captured fingerprint image clearer. The interface controller is connected to the signal conversion module and the module controller to make the digital signal transmitted by the signal conversion controller more easily accessible.

The image-sensing module has a flex/rigid composite substrate having a first rigid circuit substrate, a second rigid circuit substrate, a third rigid circuit substrate, and at least one flex circuit board. The first rigid circuit substrate, the second rigid circuit substrate, and the third rigid circuit substrate respectively and electrically connect to the flex circuit board in order to form a first composite substrate, a second composite substrate, and a third composite substrate. Each of the second composite substrate and the third composite substrate respectively is not located in the same plane and has a predetermined angle with respect to the plane where the first composite plane is located.

Abstract:
A handheld fingerprint-capturing device includes a built-in camera module for capturing an image, an image reception module having a data transmission interface, which is electrically connected to the camera module and provided with a protocol for communicating with the camera module, and a fingerprint-capturing module that is compatible with the data transmission interface for transmitting a fingerprint to the image reception module via the data transmission interface. Thus, the fingerprint-capturing module can easily integrate with the camera module in the handheld device via the data transmission interface, so that the devices can be easily integrated with each other.

Abstract:
A contact image sensing module with movement detecting function has a main circuit substrate, a linear sensor array, at least a movement detecting element, a light source, a light-guiding device, and a detecting surface. The main substrate is a flex-rigid composite substrate having a structure making the linear sensor array have a tilted angle. The linear sensor array has at least a comparison sensor corresponding to at least a movement detecting element. The movement detecting element and the comparison sensor, respectively, draw a section of reference image data and a section of comparison image data from a sensed object. After processing a shift-times deciding equation and a speed deciding equation, the moving speed of the sensed object relating to the movement detecting element and the comparison sensor can be obtained. The structure of the light-guiding device makes the light from the light source to the sensed object more uniform.
