    Abstract: A device having a health detecting function (10), a display apparatus (1), a system and a health detecting method are provided, capable of monitoring physical condition and discovering an illness in time. The device (10) having the health detecting function includes a processing module (101) and a storage module (102). The processing module (101) is configured for receiving image information of a detected person and storing the image information in the storage module (102). The image information of the detected person includes a part image of the detected person and an acquiring time and an ambient light intensity when acquiring the part image. change information of the part image of the detected person is obtained according to the part image of the detected person and a reference part image in reference part image information obtained from the storage module in a case where the ambient light intensity is greater than a predetermined value, and current physical health information of the detected person is obtained according to the change information of the part image. The storage module (102) is configured for storing the reference part image information, the reference part image information including reference a part image of the detected person accumulated before the acquiring time and/or a healthy reference part image based on age.
