The invention relates to a human body artery blood pressure measuring method based on a smart phone. A device for the method comprises a smart phone and further comprises an electrocardiograph signal measuring module. A line with earphone plugs at the two ends is used to connect the electrocardiograph signal measuring module with the smart phone to extract an electrocardiograph signal waveform. Fingertips are slightly placed on a camera and an LED (Light Emitting Diode) flash lamp of the smart phone to extract pulse waves from images photographed by the phone. The measurement of human body artery blood pressure is realized by using the relationship between the pulse waves and the electrocardiograph signals as well as the artery blood pressure.

The invention discloses a mobile phone dynamic camera flash lamp luminance compensation system and a method. The mobile phone dynamic camera flash lamp luminance compensation system and the method comprise the following steps: step A, a mobile phone camera is started and a distance detection unit and a luminance detection unit are started at the same time; step B, the distance between a mobile phone and a scene is acquired through the distance detection unit, the luminance of the scene is acquired through the luminance detection unit at the same time, and the acquired distance value and the acquired luminance value are reported back to a central proceeding unit (CPU); step C, the CPU correspondingly calls a dynamic luminance compensation database in a storer according to the distance value and the luminance value, and acquires flash lamp luminance compensation data at the current distance and the current luminance; and step D, the CPU controls a flash lamp to conduct luminance compensation processing on the photographed scene according to the acquired flash lamp luminance compensation data. According to the mobile phone dynamic camera flash lamp luminance compensation system and the method, the distance and the luminance of the photographed scene are detected through the distance detection unit and the luminance detection unit, wherein the distance detection unit and the luminance detection unit are installed at an end where the camera is located, the dynamic luminance compensation database is called to compensate the flash lamp luminance of the current photographed scene, so that optimal photographing effects of the photographed scene can be achieved, the problem that the flash lamp luminance compensation is not accurate when a mobile phone camera is used for taking photos at present is solved, and photographing effects of the mobile phone camera are improved.

The invention provides a two-dimensional code attendance checking system based on an intelligent cell phone. The two-dimensional code attendance checking system comprises a remote attendance checking management server system, a local display type two-dimensional code terminal browser webpage, an intelligent cell phone mobile attendance checking application system, an intelligent cell phone camera, an intelligent cell phone two-dimensional code identification system, an intelligent cell phone information sending system and a remote attendance checking recording information storage system. Based on a two-dimensional code technology, attendance checking scanning equipment is finished by matching of the popularized intelligent cell phone and equipment capable of surfing the Internet in a workplace; the equipment is low in cost and has the low-carbon and environmentally-friendly effects; the attendance checking is flexible and convenient and the worker attendance checking is carried out by two-dimensional code scanning, and the position of the cell phone and the matching degree in the current time are judged; qualified information is confirmed and then is sent to the remote attendance checking management server system to be stored, and an attendance checking result and an attendance checking abnormity condition are generated in real time, so that the problem that a card is punched by other one is prevented and counterfeited attendance checking records are prevented; and workers can obtain attendance checking abnormity reminding and attendance checking record inquiry from the intelligent cell phone mobile attendance checking application system in real time so as to carry out appealing explanation.

The prevention of counterfeiting labels for various products is addressed by introducing counterfeit proof labels having an optically concealed, invisible progressive shifting security safety symbols for quick identification. The label is printed on a high-resolution micro-optic photo chromogenic material. A multiple number of images of an optically compressed security safety symbol are printed on the focal plane along the linear optical center of each micro-lenticule across the entire area or a small portion of the label. Due to the optical effect of the micro-optic, the complete security safety symbol is not clearly visible at normal viewing distance. When viewing the label directly or using the camera of a mobile phone at a close-up distance or slightly bending the label, each micro-lenticule within the viewing angle projects and magnifies a small section of the compressed security safety symbol on the surface of the micro-lenticules to reassemble the complete original image of the security safety symbol for identification.The image elements that compose the compressed security safety symbols under each micro-lenticules are printed at the approximately same location on the focal plane of each micro-lenticule in relation to the linear optical center of the micro-lenticule. Therefore the same and complete reassembled image of the security safety symbol can be seen from any location of the label for quick identification. The complete reassembled image of the security safety symbol is progressive shifting following a moving viewpoint for quick and accurate identification.The color photo of the reassembled security safety symbol can be sent by a mobile phone installed with a related software to an Anti-Counterfeiting Control Center for computer matching and verification and the consumer will be advised of the result in a matter of seconds

The invention discloses a method for detecting a skin state through a mobile phone. The method comprises the steps of shooting skin of a to-be-tested user through a camera of the mobile phone, calculating state parameters of the skin according to a skin image obtained by shooting, and identifying the skin state according to the calculated state parameters of the skin. Further disclosed is the mobile phone. The mobile phone is capable of detecting the skin state. The mobile phone comprises the camera, a storage module and a processing unit, wherein the camera is used for scanning the skin so as to generate the skin image, the storage module is used for storing the skin image obtained by scanning, and the processing unit is used for calculating the state parameters of the skin according to the skin image obtained by scanning. According to the method, the camera of the mobile phone is used for scanning the skin, and the state parameters of the skin are calculated and identified according to the skin image generated by scanning. Therefore, relevant information of the skin state can be conveniently offered to the user, and the user conveniently masters the skin state at any time.
