Abstract:
1. A data processing apparatus for adjusting an image quality of a broadcast program comprising: data processing means for processing input data based on a parameter; first setting means for setting, in accordance with an operation operated when inputting the parameter, the parameter used by the data processing means; user-information providing means for providing user information to a server apparatus that statistically processes the user information, the user information including the parameter set by the first setting means and status information indicating status under which the parameter is used by the data processing means; server-information obtaining means for obtaining server information for setting the parameter; and second setting means for setting, in accordance with the server information, information regarding the parameter used by the data processing means, wherein the server-information obtaining means obtains an optimal parameter from the server apparatus, the optimal parameter being determined by the server apparatus based on a relationship between a noise amount and the parameter of each frame that is registered in the server apparatus as a same scene, the noise amount being calculated by the server apparatus based on a true value of image data of the same scene, the true value of image data being obtained by averaging the image data of a plurality of frames of the same scene registered in the server apparatus, the plurality of frames of the same scene including more than two frames, the true value approximating image data without superimposed noise amount due to broadcasting, the noise amount of the plurality of frames of the same scene having a Gaussian distribution, wherein the data processing means adjusts the image quality of the input data including the broadcast program based on the optimal parameter, wherein the status information identifies a frame by an ID of a program and an index of the frame and the server apparatus registers the parameter with the frame according to the ID and the index so that user information of a same frame obtained from a plurality of users is statistically processed, and wherein the parameter is set in accordance with the server information, which is obtained independently of user operations.
