Embodiment Construction

[0034] In the following, the technical means adopted by the present invention to achieve the intended purpose of the invention will be further described in conjunction with the accompanying drawings and the embodiments of the present invention.

[0035] see Figure 1 to Figure 3 As shown, the portable electronic device of the present invention includes a first light source 10 , an optical detector 20 and a control unit 30 .

[0036] The optical detector 20 includes at least one light detection unit 21 and at least one driving unit 22 , and the first light source 10 is connected to the corresponding driving unit 22 to be driven by it. The light detection unit 21 can receive light to generate an optical detection signal through the preset hole on the portable electronic device, and the first light source 10 can project light to the portable electronic device through the preset hole. In addition to electronic devices, the number of the photodetection unit 21 and the drive unit 2...

Abstract

A portable electronic device uses the initial heartbeat value to calculate a possible heartbeat variation. Then a reference range is determined. Only the real time heartbeat value falling in the reference range is output as a correct real time heartbeat value. Thus, the too large or too small erroneous heartbeat values influenced by the vibration noise are eliminated to precisely output the correct real time heartbeat value. Therefore, the extra vibration sensors need not to be installed to lower the cost and to reduce the volume.

Description

technical field [0001] The invention relates to a portable electronic device and its real-time heartbeat measurement method, in particular to an electronic device using optical elements for blood detection and its measurement method. Background technique [0002] With the advancement of technology, the functions that portable electronic devices can provide are becoming more and more diversified. One of the applications is as a heartbeat detection device. Users place their fingers or other body parts on the light source, and then use optical detection The detector receives the reflected light of the light to generate a blood detection signal, and the control unit obtains the heartbeat value according to the blood detection signal. The user can measure the heartbeat in a normal static state, or use a portable electronic device to monitor the heartbeat during exercise. [0003] However, if the heartbeat is measured during exercise, the user's body will inevitably vibrate durin...
