Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0025] figure 1 A schematic structural diagram of a power management system according to a preferred embodiment of the present invention is shown.

[0026] As shown in the figure, the power management system of the present invention includes: a control unit 1 , a graphics processing unit (GPU) 2 and an image acquisition unit 3 .

[0027] The image acquisition unit 3 is arranged at an appropriate position on the display screen, and is used to detect the viewing angle of the user. By setting the image acquisition unit, the user's sight angle can be detected in real time, so as to determine the position of the user's attention area in real time and dynamically at the current moment. The line of sight angle can be used to d...

Abstract

The invention discloses a power supply management system and a power supply management method. The system comprises an image collection unit (3), a control unit (1) and an image processing unit (2), wherein the image collection unit is used for detecting view angles of users, the control unit can confirm an attention region and a non-attention region except the attention region according to the view angles of the users to carry out different display strategies on the attention region and the non-attention region, and the image processing unit can set display parameters of the non-attention region according to the display strategies. The power supply management system can effectively reduces power consumption and temperature of digital processing equipment and simultaneously enables the users to achieve good user experience.

Description

technical field [0001] The present invention relates to a power management scheme for a digital processing device, and in particular, to a power management system and a power management method capable of performing optimization or weakening processing on a partial display. Background technique [0002] At present, digital processing devices have been widely used in people's daily life, such as desktop / portable computers, tablet computers, smart phones, personal digital assistants, and the like. According to the needs of users, the development trend of this kind of portable digital processing device is to meet the increasingly higher requirements of soft and hard performance, and at the same time, it should ensure that the size, volume and weight of the device will not increase accordingly, so as to meet the basic requirements of portability. . This trend requires more components to be placed in a digital processing device with limited space, and the performance of a single ...
