The invention relates to the technical field of medical image processing, in particular to intracavity image acquisition technology of a living body and more particularly an image compression method oriented to intracavity image acquisition of the living body. The image compression method oriented to intracavity image acquisition of the living body comprises the following steps of: acquiring a frequency coefficient matrix of an original image first; secondly, rearranging the frequency coefficient matrix subjected to quantization processing and carrying out entropy coding on the frequency coefficient matrix; thirdly, decoding frame data formed by the frequency coefficient matrix subjected to entropy coding and reconstructing an image; and finally carrying out deblocking effect processing on the obtained reconstructed image. The image processing method disclosed by the invention has the capabilities of providing a higher image compression rate, reducing the system algorithm complexity in the body, improving the subjective quality of a restored image and providing convenience for a doctor to read the image, thereby providing powerful technical support for acquisition and processing of medical images.
