Embodiment

[0019] figure 2 It is a flowchart of a method for implementing MIPI CSI-2 multi-channel low-frequency transmission provided by an embodiment of the present invention. Such as figure 2 As shown, the method mainly includes the following steps:

[0020] Step 21, acquiring image data.

[0021] Step 22, performing channel allocation on the image data according to the number of channels set by the user.

[0022] Step 23: Add header information indicating the image format type before each channel of the allocated image data, and then output it.

[0023] In the embodiment of the present invention, the image data output by each channel is combined with the packet header information including the image format type according to the image output format preset by the user to obtain a complete data packet, and then output to the outside.

[0024] For better understanding, see also image 3 A schematic diagram of the work is shown.

[0025] Such as image 3 As shown, after the input...

Abstract

The invention discloses a method for achieving an MIPI CSI-2 multichannel low frequency transmission. The method includes acquiring image data; conducting channel distribution on the image data according to the channel number set by users; adding package information marking the image format and type in front of each channel of the distributed image data and outputting the information. By means of the method, the circuit power consumption and operation efficiency can be reduced, and the image transmission speed is further improved.

Description

technical field [0001] The invention relates to the technical field of image transmission, in particular to a method for realizing MIPI CSI-2 multi-channel low-frequency transmission. Background technique [0002] With the rapid development of multimedia technology, various video electronic products are being popularized at an extremely fast speed. Moreover, higher requirements are put forward for the image transmission speed, and the image pixels are required to be larger and larger, and the transmission frame rate is higher and higher. figure 1 A schematic diagram of the basic working principle of existing image transmission is given. Such as figure 1 As shown, first the image acquisition unit acquires the image data, and then outputs it to the MIPI processing unit, and the MIPI processing unit performs processing such as packaging on the image data, and finally outputs it according to the time sequence required by the MIPI protocol. [0003] However, the solution in th...
