Fig. 2 is the structural drawing of the portable terminal Anti-peeping device that provides of the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The embodiment of the invention, the default maximum number that can browse simultaneously the secret file, start front-facing camera and catch the front number of browsing of screen and the size of people's face, when the number of browsing is browsed number greater than maximum, start the display properties of dynamically adjusting the secret file, realized that a kind of picture processing is simple, the anti-peeping method of Initiative Defense.
Embodiment one
Be illustrated in figure 1 as the process flow diagram of the anti-peeping method of portable terminal that the embodiment of the invention provides, details are as follows:
In step S101, the maximum that the secret content is set is browsed number simultaneously.
In embodiments of the present invention, setting can be browsed the maximum number of this secret file simultaneously, as: the topsecret papers maximum is browsed simultaneously number and is set to 1 people, and the secret papers maximum is browsed simultaneously number and is set to 2 people, by that analogy, each secret file is arranged maximum and browse simultaneously number.
In step S102, start front-facing camera, the image that comprises people's face information that the identification front-facing camera obtains is determined the quantity of people's face in the image and the size of everyone face.
In embodiments of the present invention, when terminal is browsed the secret content, start front-facing camera, the image that comprises people's face that the identification front-facing camera obtains is determined the quantity of people's face in the image and the size of everyone face, and its step is specially:
A, described camera obtain the image in the terminal predeterminable range scope, identify the quantity of the people's face in the described image and/or the size of people's face; And/or,
B, described camera obtain the consecutive image in the preset time period, identify the quantity of people's face of sustainable existence in the described consecutive image and the size of everyone face.
According to the picture of front-facing camera seizure, determine to browse the size of every people's face in the number simultaneously, method is:
For every people's face arranges the recognition of face frame of a rectangle, according to the length and width of every people's face in the picture length and width of this recognition of face frame are set, determine the size of people's face, and store the size data of described people's face into portable terminal.
In step S103, when people's face quantity is greater than predetermined threshold value in the described image, according to quantity and the dynamic display properties of adjusting terminal of size of described people's face.
In embodiments of the present invention, determine whether to start dynamic adjustment secret content according to the described number of browsing, determine dynamically to adjust the display properties of secret file according to the size of described people's face, the display properties of described secret file specifically comprises: the size of law-hand, the color of law-hand, the light and shade contrast of mobile terminal screen.Wherein, the size of the attribute of secret file and described people's face is inversely proportional to, and the recognition of face frame is larger, and the attribute of described secret file is just less, and be embodied in: law-hand is less, and the color of law-hand is more shallow, and the contrast of screen is less.
The method of dynamically adjusting the display properties of terminal according to the quantity of people's face and size is specially: people's face that maximum is browsed outside people's face that number determines simultaneously is set as effective people's face, determines the size of the recognition of face frame of effective people's face.Because maximum is browsed the definite people's face of number is in camera when browser document dead ahead simultaneously, so the maximum recognition of face frame size of browsing simultaneously the definite people's face of number is dynamically adjusted the display properties of terminal so for maximum according to people's face of browsing simultaneously the recognition of face frame maximum outside the definite people's face of number in maximum.
Calculating the attribute of adjusting the secret file according to the size of recognition of face frame simultaneously is the needs times, at this Preset Time can be set for the dynamic adjustment of secret file, if surpass described preset value computing time, then at first pass through: the current states of being peeped that are in of method reminding user such as alarm, literal, vibrations, allow the user make first and remind, then at the attribute of adjusting the secret file.
The embodiment of the invention, the default maximum number that can browse simultaneously the secret file, start front-facing camera and catch the front number of browsing of screen and the size of people's face, when the number of browsing is browsed number greater than maximum, start the display properties of dynamically adjusting the secret file, realized that a kind of picture processing is simple, the anti-peeping method of Initiative Defense.
