Embodiment Construction

[0034] figure 1 A schematic diagram of the application of the image sensing device 1 according to the first embodiment of the present invention is shown. The image sensing device 1 is a fingerprint sensing device or other biometric sensing devices. In this embodiment, the image sensing device 1 is particularly a fingerprint sensing device, which senses an object 2 such as a finger. When the finger moves above the sensing device, the sensing device can not only read the fingerprint data, but also obtain the information of the sensing finger moving direction for other applications.

[0035] For practical applications, see Figure 5 , you can use the clockwise arc movement of your finger on the sensing device to enlarge the photo displayed on the screen, or as Figure 6 Generally, the photo is zoomed out by turning the finger to the left. Such an increase in functionality is not provided by current touchpads or any joystick, and is also the core of the present invention.

Abstract

The invention discloses an image sensing device and an electronic device using the same. The image sensing device at least comprises an image sensor and a processing unit, wherein the image sensor senses a plurality of first images of a moving object in a first mode to output a plurality of first image signals corresponding to the first image, and the processing units receives the plurality of first image signals and acquires a curvilinear motion path of the moving object according to the first image signals to output curvilinear motion identification information. The invention also provides an electronic device using the image sensing device. The image sensing device and the electronic device allows a use to use one image sensor to achieve image sensing, picture zooming control and picture rolling effect. The image sensor can directly replace the traditional touch pad and has functions of identity authentication, zooming control and picture rolling.

Description

technical field [0001] The present invention relates to an image sensing device and electronic equipment using the same, in particular to a biometric sensing device (especially a fingerprint sensing device) and electronic equipment with the sensing device. Background technique [0002] Traditional electronic devices, such as notebook computers, personal digital assistants (PDAs) or mobile phones, are equipped with a touch pad or several direction keys, allowing users to control the device through the touch pad or direction keys The operation of a cursor in an electronic device or the selection of a specific function. [0003] On the other hand, more and more electronic devices provide data security functions. In addition to traditional password protection, using the holder's biological data, such as fingerprints, iris, face, etc., to protect the data in electronic devices is increasingly common practice. [0004] In order to meet the needs of many users, electronic devices...
