New description: [New type of 彳 彳 彳 】 】 】 [0001] The present invention relates to an electronic photo frame, and more particularly to an electronic photo frame for intelligently controlling display brightness. [Prior Art] [0002] At present, with the improvement of people's living standards, various electronic products are becoming more and more popular, and people often use digital cameras to take digital photos. Therefore, electronic photo frames as digital photo display devices have also become popular. [0003] However, when the electronic photo frame is used, the brightness of the display unit is too high, which may damage the user's vision. The brightness of the display unit is too low, which makes it difficult for the user to recognize the displayed screen information. Therefore, if the electronic photo frame can effectively control the display brightness of the display unit according to the surrounding brightness environment, it will not only save energy but also contribute to vision health.

[0005] An electronic photo frame capable of intelligently controlling display brightness, comprising a power source; a display panel; a power management unit for managing power supply to the display panel by the distribution power source; and a brightness sensing unit for Detecting ambient brightness information and transmitting it to a processing unit; a shaking sensing unit for sensing a change in the center of gravity of the electronic photo frame, generating a shaking command signal when sensing the change of the center of gravity of the electronic photo frame, and transmitting the shaking command signal to The processing unit; and a processing unit, configured to change the display form number A0101 of the display panel according to the received shaking command signal and the ambient brightness information, and the brightness of the M366952. [0006] Compared with the prior art, the present invention not only saves electric energy, but also helps to protect vision. Embodiments [0007] FIG. 1 is an internal architecture diagram of an electronic photo frame according to a preferred embodiment of the present invention. The electronic photo frame 1 includes a processing unit 10, a power source 20, a brightness sensing unit 30, a shaking sensing unit 40, a power management unit 50, a display panel 60, a memory 70, an input unit 80, and an interface. Unit 90. The display panel 60 is used to implement display of various multimedia files on the electronic photo frame 1. The input unit 80 receives the user input to implement the user's operation of the electronic photo frame 1. Various multimedia files such as an audio file, a video file, and a digital picture are stored in the memory 70. [0009] The memory 70 also stores a correspondence table of the preferred display luminance values corresponding to the interval of the ambient luminance. In the correspondence table, the ambient brightness value is divided into several ambient brightness intervals, such as dark, dark, normal, bright, and bright. Each of the different ambient brightness intervals corresponds to a preferred display brightness value. The correspondence table may be stored in the memory body 70 by the system preset, or the user may set different ambient brightness intervals and their corresponding preferred display brightness values. The interface unit 90 can be a wired interface (such as a USB interface or the like) or a wireless interface (such as a wireless communication module), thereby implementing connection of the electronic photo frame 1 with other electronic devices. [0011] The power source 20 is connected to the power management unit 50. The power source 20 can be a battery form number A0101 page 4 of 9 or an AC/DC adapter module. The power management unit 50 is connected to the processing unit 10, the brightness sensing unit 30, the shaking sensing unit 40, and the display panel 60, respectively, and distributes operating voltages thereto. In the embodiment, when the electronic photo frame 1 is connected to the power source 20, the power management unit 50 distributes the operating voltage to the processing unit 10 and the shaking sensing unit 40, so that the processing unit 10 and the shaking sensing unit 40 are in an active state, but may not Power other components to make them inactive. [0012] The brightness sensing unit 30 is configured to detect current ambient brightness information and transmit the detected ambient brightness information to the processing unit 10. [0013] The shaking sensing unit 40 can be a gravity sensor or an acceleration sensor for sensing whether the electronic photo frame 1 is shaken*, that is, whether the center of gravity of the electronic photo frame 1 changes. If the shaking sensing unit 40 senses that the center of gravity of the electronic photo frame 1 changes, a shaking command signal is generated, and the shaking command signal is sent to the processing unit 10 connected thereto. [0014] After receiving the shaking command signal, the processing unit 10 controls the power management unit 50 to allocate a voltage to the brightness sensing unit 30, thereby turning on the brightness sensing unit 30. The brightness sensing unit 30 transmits the detected ambient brightness information to the processing unit 10. The processing unit 10 converts the ambient brightness information into an ambient brightness value by analog-to-digital conversion, and determines an ambient brightness interval in which the ambient brightness value is located and a preferred display brightness value corresponding to the interval from the correspondence table of the memory 70. The processing unit 10 changes the display brightness of the display panel 60 in accordance with the acquired preferred display brightness value. [0015] In other embodiments of the present invention, the preferred display brightness value corresponding to the ambient brightness interval may also be replaced by a display brightness interval, and the processing unit form number A0101 5th page/total 9 pages M366952 10 may be displayed according to the display. Any value within the luminance interval changes the display brightness of the display unit 60.
