Image processing assembly and method capable of achieving image rotation

The invention discloses an image processing assembly and method capable of achieving image rotation. The image processing assembly comprises a decoding unit, an image processing unit and a coding unit. The decoding unit is used for receiving an original image signal, converting the original image signal into a digital RGB signal and outputting the digital RGB signal. The image processing unit is used for conducting cutting, frame rate conversion, rotation and zooming on the digital RGB signal. The coding unit is used for receiving the processed digital RGB signal, converting the processed digital RGB signal into a processed image signal and outputting the processed image signal to an external display device. The image processing unit comprises a cutting module, a first frame rate conversion module, a rotation module, a zooming module, a second frame rate conversion module and a signal output module. By means of the image processing assembly and method, the image signal can be cut, rotated, zoomed and the like, and synchronous and letter-box-free display of screen display content on an intelligent terminal and screen display content on the external display device can be achieved; the frame rate of the image signal is converted into a frame rate matched with that of the external display device so that transition of a dynamic picture in the image signal can be smoother, and the viewing feeling of human eyes can be promoted more easily.
