Image feature obtaining method and electronic device

A second device, comprising:

• at least one processor;
• and
• at least one memory comprising computer program instructions that, when executed by the at least one processor, cause the second device to perform operations including:
• receiving, by the second device from a first device, a first obtaining request that requests to obtain an image feature from the second device;
• creating, by the second device in response to the first obtaining request, a first window having a same size as a size of a display of the second device, with the first window being a global transparent window located over all applications displayed on the display of the second device;
• obtaining, by the second device, a first image in a first closed area determined based on a first screen capture operation by a stylus on the first window;
• analyzing, by the second device, the first image in the first closed area to obtain a first feature of a detected color of the first image;
• closing, by the second device, the first window after the second device obtains the first image;
• and
• sending, to the first device, the first feature of a detected color of the first image via a data exchange channel between the first device and the second device.

A system, comprising a first device and a second device, wherein

• the second device is configured to:
• receive, from the first device, a first obtaining request that requests to obtain an image feature from the second device;
• create, in response to the first obtaining request, a first window having a same size as a size of a display of the second device, with the first window being a global transparent window located over all applications displayed on the display of the second device;
• obtain a first image in a first closed area determined based on a first screen capture operation by a stylus on the first window;
• analyze the first image in the first closed area to obtain a first feature of a detected color of the first image;
• close the first window after the second device obtains the first image;
• and
• send the first feature of the detected color of the first image to the first device via a data exchange channel between the first device and the second device;
• and
• the first device is configured to:
• receive the first feature of the detected color of the first image via the data exchange channel;
• and perform an image editing operation based on the first feature of the detected color of the first image and an operation by the stylus on a display of the first device.
