Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The invention provides a method for transmitting camera image data, such as figure 1 As shown, the method includes the following steps:

[0045] S1. Predefine an image pixel position function and an image pixel difference function.

[0046] In order to more accurately obtain the pixel data in a frame of image obtained by the camera, the function of the obtained data is defined in advance. Specifically, the position function of the image pixel and the difference function of the image pixel are defined. If the image The position of a certain pixel and the data related to the pixel...

Abstract

The invention provides a method and a system for transmitting camera image data. The method is characterized in that a frame of image data acquired by a camera at a camera end is compressed, the compressed data is transmitted to a central processor, and the central processor is used for reducing the received data, so that time delay caused by transmission of large-scale data between the camera and the central processor is lowered greatly. Moreover, in the method and system, the difference in image pixel data between adjacent pixels in a frame of practically-shot image is small, so that the data scale can be lowered greatly by replacing the difference values among adjacent pixel image data with original image data, and the aim of rapidly transmitting is fulfilled.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a method and system for transmitting camera image data. Background technique [0002] At present, the camera is a standard device for mobile terminals, and the camera is developing towards high-definition and high-pixel resolution. Therefore, the data volume of a photo taken by the user using the camera function of the mobile terminal is very huge. For example, the current mainstream The photos taken by the 13-megapixel camera are several megabytes in size, and it often takes a certain amount of time for the camera to transmit such huge image data to the central processing unit, which makes the user feel that the camera responds slowly. [0003] In the prior art, in order to improve this defect, mobile terminal manufacturers can only use high-speed cameras to improve image transmission speed, but the cost of high-speed cameras is more than twice that of ordinary cameras. ...
