The ratio of three optical signal absorption amounts, and then the blood oxygen such as the such as blood oxygen saturation that may determine that user
Information.Thus, blood oxygen saturation that can obtain user according to herein described method etc. is important
Physical signs, is conducive to effectively monitoring the health status of user.Further, permissible
These health status relevant informations are sent to the kith and kin of user or user, to remind user to note
Meaning health.
In addition, it is necessary to explanation, in order to improve the accuracy of blood oxygenation information detection further,
In the case of user's body and described display screen have multiple contact position, it is also possible to determine
Multiple (comprising two) target area, performs said method, then described in COMPREHENSIVE CALCULATING respectively
Blood oxygenation information.
In another embodiment, described step S220 can be further:
S220 ': in response to display screen described at least one location contacts described in user's body and
Meet a preset trigger condition, described display screen determines described target area.
It is to say, according to user's request, this Shen can be limited by described preset trigger condition
Please described method the most just perform.
In one embodiment, described preset trigger condition includes: described display screen collection
Fingerprint belong to a predetermined fingerprint set.Wherein, described predetermined fingerprint set can include
It is previously obtained the fingerprint of the user of mandate, such as, is a smart mobile phone at described display screen
In the case of display screen, described predetermined fingerprint set can include joining of owner and owner
Even fingerprint.
In one embodiment, user for convenience, described target area and described display screen
The region gathering described fingerprint on curtain is identical.Such as, described display screen can be by user in institute
State contact area on display screen as fingerprint collecting region, if the fingerprint gathered belongs to institute
State predetermined fingerprint set, the most described contact area is defined as described target area, so
Rear execution described blood oxygenation information detection method.
In another embodiment, described preset trigger condition includes: described display screen institute
The application program of the front stage operation of the electronic equipment belonged to belongs to a predetermined application set.
Described predetermined application set includes that some suitably detect answering of the blood oxygenation information of user
Use program.In other words, at these application programs in the case of front stage operation, user's body
Contact with described display screen is relative stable.Such as, can in described predetermined application set
To include: voice procedure, e-book program, video reproduction program etc..By this restriction,
Can be during user normally use electronic equipment, in the detection of efficiently and accurately accidentally
The blood oxygenation information of user.
In another embodiment, described transmission subregion include one first transmission subregion and
One second sends subregion.
Accordingly, described step S240 specifically may include that
S240 ": control described first transmission subregion and send described in described first time period
First optical signal.
