Problems solved by technology

Therefore, in the processing method of the prior art, any change in the displayed image on the display interface will cause the image processing tool to recalculate the overlay processing effect, resulting in the image processing tool frequently performing overlay calculations and frequently occupying the resources of the hardware device, such as Central processing unit (CPU) and memory resources, resulting in high resource consumption of hardware devices

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] image 3 It is a flow chart of the method for locally selecting an image according to the present invention; see image 3 , the process includes:

[0033] Step 301. Receive a selection trigger instruction.

[0034] The selection trigger command described here is generally issued by the user. For example, the user edits an image to be processed. First, the image to be processed needs to be opened, and the user needs to send the address (local address or network address) of the image to the image processing tool. , the image processing tool reads the original image data of the image to be processed from the image address, and displays the image on the interface of the image processing tool, and the image processing tool displays buttons such as "select" and "cropping" , the user clicks this button to issue a selection trigger ...

Abstract

The invention discloses a device for locally selecting and processing an image. The device comprises a trigger module, an initializing module, a preprocessing module, and a selected area processing module, wherein the trigger module is used for receiving a selection trigger module; the initializing module is used for generating a bottom image layer and an upper image layer; the preprocessing module is used for copying the original image and conducting designated preprocessing on the copied original image; the selected area processing module respectively displays the preprocessed image or the original image in the bottom image layer and the upper image layer; the effects of the image displayed by the upper image layer and the bottom image layer are distinguished; the pixel positions of the image displayed by the upper image layer and the bottom image layer are overlapped. With utilization of the device disclosed by the invention, the resource consumption of the hardware equipment can be reduced.

Description

technical field [0001] The present application relates to the technical field of image data processing, and in particular to a method and device for performing partial selection processing on an image. Background technique [0002] Image data processing technology refers to the technology of analyzing and processing digital images with data processing equipment such as computers, smartphones, and tablets to achieve the desired results. A digital image refers to a large two-dimensional array obtained by sampling and digitizing with digital cameras, scanners and other equipment. The elements of the array are called pixels, and their values ​​are an integer, called gray values. The main content of image data processing technology includes cropping, scaling, partial processing, adding special effects, compression, enhancement and restoration of images. At present, image data processing technology is generally referred to as image processing technology for short. Currently, the...
