Embodiment 1

[0064] refer to figure 1 , is a flow chart of Embodiment 1 of an information processing method provided by this application. The information processing method can be applied to, but not limited to, smart wrist-worn devices with display screens and fingerprint collection devices, smart phones, tablet computers, personal Portable terminal equipment such as digital assistants, or can also be applied to personal computer equipment such as notebooks, all-in-one computers, and desktop computers. The display screen of the electronic device includes a touch sensing area and a display output area, the display output area of ​​the display screen tends to coincide with the touch sensing area of ​​the display screen, and the display screen may be but Not limited to capacitive touch screens or resistive touch screens, etc.

[0065] Such as figure 1 As shown, in this embodiment, the information processing method includes:

[0066] Step 101. Obtain detection parameters if the fingerprint ...

Embodiment 2

[0083] As an optional embodiment of this application, refer to figure 2 The flow chart of the information processing method shown, in this embodiment, the information processing method may also include:

[0084] Step 201, if the current electronic device invokes the fingerprint collection device, display a prompt area through the display screen.

[0085] Wherein, the prompt area is used to instruct the user to touch input in the prompt area, so that the fingerprint collection device obtains fingerprint information corresponding to the touch input.

[0086] The prompt area belongs to a part of the display area of ​​the display screen, refer to image 3 , image 3 A schematic diagram of the prompt area within the display area of ​​the display screen of the electronic device is provided.

[0087] The prompt area corresponds to the fingerprint collection area of ​​the fingerprint collection device, and specifically, the prompt area corresponds to at least part of the fingerpri...

Embodiment 3

[0104] As an optional embodiment of this application, refer to Figure 6 The flow chart of the information processing method is shown. In this embodiment, the determination of whether the external ambient light affects the fingerprint collection device to collect the fingerprints of the fingers in the display area of ​​the display screen based on the detection parameters can also be performed through the following Process implementation:

[0105] Step 601. If the current electronic device invokes the fingerprint collection device, obtain ambient light parameters of ambient light based on the ambient light sensor.

[0106] The ambient light parameter may be the illumination parameter of the external ambient light, and the illumination parameter may specifically include but not limited to the illuminance of the external ambient light, that is, lux (lux). Correspondingly, the ambient light sensor may Yes but not limited to light sensor.

[0107] Step 602: If the ambient light p...

Abstract

The invention provides information processing and electronic equipment. The invention discloses an information processing method and electronic equipment. The fingerprint acquisition device is used for acquiring detection parameters according to the first exposure time and the second exposure time, determining whether external ambient light affects acquisition of the fingerprint by the fingerprintacquisition device based on the detection parameters, if not, acquiring the fingerprint of the finger by the fingerprint acquisition device based on the first exposure time, and if yes, acquiring thefingerprint of the finger by the fingerprint acquisition device based on the second exposure time. Wherein the second exposure time is shorter than the first exposure time. According to the scheme ofthe invention, under the condition that the external ambient light influences the fingerprint acquisition device to acquire the fingerprint, the fingerprint is acquired; according to the fingerprintacquisition device, the light incoming amount of the photosensitive element of the fingerprint acquisition device can be effectively reduced by adopting a relatively short exposure time, namely the second exposure time, so that the excessive exposure of the fingerprint image acquired by the fingerprint acquisition device can be avoided to at least a certain extent, and the quality of the fingerprint image acquired by the fingerprint acquisition device is correspondingly and better ensured.

Description

technical field [0001] The present application belongs to the field of electronic technology, and in particular relates to an information processing method and electronic equipment. Background technique [0002] At present, on terminal devices such as smart phones, tablet computers, or personal digital assistants (PDA, Personal Digital Assistant), it is relatively common to authenticate users based on fingerprint matching. [0003] This method of authenticating users based on fingerprint matching needs to first collect user fingerprints, wherein, when collecting user fingerprints, the fingerprint collection device may be affected by external ambient light (especially in strong light environments) and cause the collected If the fingerprint image is over-exposed, the amount of effective fingerprint information collected will be relatively low, thereby affecting the quality of the collected fingerprint image. Contents of the invention [0004] In view of this, the purpose of...
