Problems solved by technology

The image processing flow of the handheld terminal lacks YUV domain processing at the back end of the main controller, and some specific algorithms will be difficult to implement
[0004] Due to the limitations of the current handheld terminal processing processor or additional algorithms need to be processed in the YUV domain, if the CPU is used for processing, such as multi-frame synthesis, noise reduction, beauty, etc., it needs to consume too much CPU resources. DSP processing, due to the current architecture design, can only be between the image acquisition module and the main controller, which belongs to the front end for the main control, and there is no YUV domain back-end data after the main control processor completes the processing. Method for external DSP processing

Embodiment Construction

[0041] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] The problem to be solved in this application is how to process the image at the back end of the handheld terminal device, and then transmit it back to the main control processor for secondary processing or storage, so as to meet the requirements of specific algorithms.

[0044] Compared with the way of using the handheld terminal CPU to perform YUV domain algorithm, the solution of the present invention has the advantage of reducing the CPU load, and can also achieve the processing effect of the flagship platfo...

Abstract

The embodiment of the present invention discloses an image processing terminal and an image processing method, which belong to the technical field of image processing. The image processing terminal includes: a camera, which acquires a target image; a main controller, which has a first An input interface and a first output interface, the first input interface receives the target image from the camera device; a display screen, the display screen is connected to the first output interface, and the display screen displays the first a preview image output by an output interface; and an external image processor, which processes the target image and sends the processed target image to the main controller. Through the solution of the present application, the efficiency of image processing is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image processing terminal and an image processing method. Background technique [0002] At this stage, there are two ways for the terminal equipment to collect images from the camera for processing, the common way: (1) use the internal processor module of the terminal equipment, such as ISP, to perform image processing, and realize the conversion from RAW data to YUV data. (2) Use an external processor module, such as an external DSP, to process the image, realize the conversion from RAW data to YUV data, and then input it to the terminal device processor for storage. [0003] figure 1 Shown is the flow chart of typical image acquisition and processing of the current handheld terminal. It can be seen that the entire processing process is pipelined to convert the data from the RAW domain to the YUV domain. If the image is processed by an external DSP, the processed T...
