It should be added that, in actual implementation, the digital photo frame 300 will not detect the current status of the offline instant messaging account through the API.

As shown in "Figure 4", "Figure 4" is a schematic diagram of applying the present invention to adjust the display position of the instant messaging account according to the difference between companionship points and missing points. In practical implementation, when the digital photo frame 300 calculates the gap value, it subtracts the missing points from the companion points. For example, suppose the companion points of the first instant messaging account 411 are 100 and the missing points are 90. , the calculation module 115 will calculate the difference between the two (ie: value -10); assuming that the companion point of the second instant messaging account 412 is a value of 60, and the number of missing points is a value of 90, the difference between the two is a value 30. The unit of the points may be a time unit, for example: hour, minute, second. At this moment, the manner of displaying the instant messaging account in the communication block 400 can be based on The gap value sorts the corresponding instant messaging accounts from high to low for the viewer to choose. In this example, since the difference value of the first instant messaging account 411 is -10, and the difference value of the second instant messaging account 412 is 30, as shown in "Figure 4", the second The first instant messaging account 412 ranks before the first instant messaging account 411. In this way, the viewer can conveniently select the instant messaging account 412 that is arranged at the top (that is, it means that the viewer misses the person longer than the time that the person spends with the viewer), and input the information through the message input block 420 Instant message. In actual implementation, the message input block 420 may allow input of instant messaging messages in text or voice.

To sum up, it can be seen that the difference between the present invention and the prior art lies in the connection with the instant messaging server program through the application programming interface, and the connection with the storage module that stores the facial features and the corresponding instant messaging account, when the digital photo frame When playing an image, perform face recognition according to the played image and facial features in real time to obtain the corresponding instant messaging account, and obtain the current status of the instant messaging account through the application program interface, and prompt when the current status is not busy Image viewers are allowed to establish instant messaging with each other, and then realize long-distance listening and companionship through instant messaging. This technical means can solve the problems existing in the previous technology, and then achieve the technical effect of reducing the incidence of depression in the elderly.
