摘要： The present invention provides an image processing method, an electronic device, and a readable storage medium. The method comprises: obtaining an original image, determining whether the current original image contains a cavity; if the current original image contains a cavity, increasing the frame rate based on the original frame rate; if the current original image does not contain a cavity, maintaining the original frame rate for image capturing. The present invention can automatically adjust the frame rate according to the actual images captured by a capsule endoscope, improving the capture of intestinal images, reducing the probability of missing shots, and achieving the goal of saving power, while enhancing the efficiency of capsule endoscope usage.
