Embodiment Construction

[0045] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, which are for reference and illustration purposes only, and do not limit the scope of the patent protection of the present invention.

[0046] One aspect of an embodiment of the present invention provides an image display method, including:

[0047] Step 1. The first terminal and the second terminal establish a connection according to a preset interconnection protocol.

[0048] In this embodiment, the first terminal is an in-vehicle information system, the second terminal is an Android mobile terminal, and the preset interconnection protocol is Android Auto.

[0049] Step 2: The first terminal acquires its own display screen resolution.

[0050] In this embodiment, the first terminal (vehicle information system) may store its own display screen resolution, and when necessary, just read the stored own display screen resolution.

[0051] Step 3: The fi...

Abstract

The present invention provides an image display method and device. The method includes: step 1, the first terminal establishes a connection with the second terminal according to a preset interconnection protocol; step 2, the first terminal obtains its own display screen resolution; step 3, the first terminal Calculate the corresponding image frame according to its own display screen resolution and the resolution supported by the second terminal, and register the image frame and its own display screen resolution with the second terminal; step 4, the second terminal judges Whether it supports the output of an image with a matching resolution corresponding to the resolution registered by the first terminal, if yes, add a corresponding image border to the image with the matching resolution and output it, otherwise add a corresponding image to the image with the default resolution Output after the frame; step 5, the first terminal processes and displays the image output by the second terminal after adding the image frame. The invention realizes the distortion-free display of any resolution image.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to an image display method and device. Background technique [0002] Generally speaking, the resolution of the display screen of the vehicle information system is a fixed value, and the common resolutions are 800X480, 960X540, 1024X600, 1280X720, 1280X800, 1920X1080 and so on. At present, when an image of the same resolution is displayed on the display screen of the in-vehicle information system with different resolutions, there are different stretching ratios. There are inconsistencies that eventually lead to a mis-scaled picture when full screen is displayed on the telematics display. [0003] Therefore, the existing technology needs to be further improved. SUMMARY OF THE INVENTION [0004] The present invention provides an image display method and device, aiming at solving the defects in the prior art and realizing the distortion-free display of images o...
