Classification: CPC H  G | IPC G  H

Claim 18:
19. A display apparatus comprising:
a display configured to display an image;
a communication interface configured to receive a video signal;
a video decoder configured to decode the video signal; and
an artificial intelligence (AI) scaler configured to adjust a resolution of the image by processing the decoded video signal,
wherein the AI scaler comprises:
a look up table (LUT) control module;
a parameter extraction module;
a filter control;
a deep neural network (DNN) comprising a plurality of filters of the DNN, wherein each filter of the plurality of filters of the DNN comprises a convolutional filter and a nonlinear function and an intermediate output is available including an output of the convolutional filter before a processing by a the nonlinear function, the intermediate output of each filter of the plurality of filters of the DNN forming a plurality of intermediate outputs, and
a second filter configured to generate a high resolution image based on an output of the DNN,
wherein, in a first artificial intelligence (AI) processing corresponding to an image analysis mode, the AI scaler is configured to route the plurality of intermediate outputs to the output of the DNN and route the plurality of intermediate outputs to the LUT control module, wherein the parameter extraction module and the filter control are configured to control the second filter based on the plurality of intermediate outputs,
and wherein, in a second AI processing which is independent of input image characteristics, the AI scaler is configured to provide the output of the DNN based on the nonlinear function and the second filter is configured to up-sample the output of the DNN without regard to the input image characteristics associated with the decoded video signal.
