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] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

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

[0043] The problem to be solved by this application is how to perform image processing 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 method of using the handheld terminal CPU to perform the YUV domain algorithm, the solution of the present invention has the advantage of reducing the CPU load. For platforms or devices with insufficient process...

Abstract

The embodiment of the invention discloses an image processing terminal and an image processing method, belonging to the technical field of image processing. The image processing terminal comprises a camera device, a main controller, a display screen and an external image processor, wherein the camera device is used to acquire a target image; the main controller is provided with a first input interface and a first output interface, and the first input interface receives the target image from the camera device; the display screen is connected to the first output interface, and the display screendisplays a preview image output by the first output interface; and the external image processor processes the target image and transmits the processed target image to the main controller. Through thescheme of the application, the efficiency of image processing can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a terminal and an image processing method based on image processing. Background technique [0002] At this stage, the terminal equipment collects the image of the camera for processing. There are two ways. The common method is: (1) Use the processor module inside the terminal equipment, such as ISP, to perform image processing and realize the conversion of RAW data to YUV data. (2) Use an external processor module, such as an external DSP, to perform image processing, realize the conversion of 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 the typical image acquisition and processing of the current handheld terminal. It can be seen that the entire processing process is a pipeline method to convert the data from the RAW domain to the YUV domain. If the image is processed by a...
