Claim Text:
1. An image processing apparatus comprising: a graphics processing unit (GPU) exhibiting an image process state that processes image data to perform special video effects on the image data; a first computer that controls the graphics processing unit; an intermediate image storage unit that stores image data generated by the graphics processing unit; an image input unit that provides input image data; an image switching unit that is supplied with input image data and stored image data and exhibiting an image process state to selectively output a plurality of image data; an image combining unit that is supplied with the image data output from the image switching unit and exhibiting an image process state to combine the image data stored in the intermediate image storage unit and the input image data; an image output unit that outputs the image data combined by the image combing unit; a second computer that controls the image switching unit and the image combining unit; a connecting unit that connects the first computer and the second computer to synchronize the operations of the first and second computers with the image data processed by the graphics processing unit; and an image process state storage unit that stores GPU control data, image switching unit control data and image combining unit control data corresponding to a predetermined image process state of the respective GPU, image switching unit and image combining unit, wherein, when a restoration of an image process state is instructed, the first computer causes a change in the image process state of the graphics processing unit based on the GPU control data stored in the image process state storage unit, and the second computer causes a change in the image process states of the image switching unit and the image combining unit based on the image switching unit control data and the image combining unit control data, respectively, stored in the image process state storage unit, in synchronization with the change of the image process state of the graphics processing unit.
