Embodiment 1

[0023] Such as figure 1 As shown, this embodiment provides a method for determining an on-screen display mode, including the following steps:

[0024] Step 11. Determine the local longitude, latitude and date of the day. The date is represented by year, month and day; the current date, time and local latitude and longitude can be obtained by performing positioning, that is, receiving relevant data sent by GPS satellites.

[0025] Step 12, determine the sunrise time and sunset time according to the longitude, latitude and today's date. For the convenience of description, determining the sunrise time and sunset time will be described later.

[0026] Step 13. Determine the screen display mode according to the sunrise time, sunset time and current time. The screen display mode can be in two ways, one is to include day mode and night mode, and the other is to include day mode, night mode and transition mode.

[0027] When the screen display mode is the first one, that is, when t...

Embodiment 2

[0242] Such as figure 2 As shown, this embodiment provides a screen display mode determination device, including: a first determination unit for determining the local longitude, latitude and date of the day; a second determination unit for determining according to the longitude, latitude and date of the day Sunrise time and sunset time; the third determination unit is used to determine the screen display mode according to the sunrise time, sunset time and current time.

[0243] The screen display mode includes a daytime mode and a nighttime mode, and the third determination unit specifically includes: a first condition selection unit for judging that the current time is before the sunrise time and after the sunset time, and starts the first setting unit; when the current time is after the sunrise time and before the sunset time, start the second setting unit, the second setting unit is used to set the screen display mode to the daytime mode; the first setting unit is used to ...

Abstract

The embodiment of the invention provides a method and a device for determining a screen display mode, and solves the problems of an inconvenient manual switching mode and an automatic switching mode in the prior art. The method comprises the following steps of: determining local longitude and latitude and current date; determining a sunrise time and a sunset time according to the local longitude and latitude and the current date; and then determining the screen display mode according to the sunrise time, the sunset time and the present time. According to the embodiment of the invention, the screen display mode is determined by determining the sunrise time and the sunset time according to the local longitude and latitude and the present date, so that the screen display mode basically accords with the actual situation.

Description

technical field [0001] The invention relates to a switching technology, in particular to a method and device for determining a screen display mode. Background technique [0002] In order to protect people's eyesight and improve visual effects, currently used navigators have a screen mode switching function on the map screen. The screen modes include a day mode and a night mode. There are two modes of switching: manual switching and automatic switching. [0003] Manual switching mode is to manually set the screen mode according to the external situation. For example, when it is dark, manually set the screen mode to the night mode; during the day, manually set the screen mode to the day mode. [0004] When the automatic switching method is selected, the system will automatically switch according to the GPS (Global Positioning System, Global Positioning System) time. For example, when the current time is before sunrise time and after sunset time, the screen display mode is ...
