Video display apparatus and video display method
View Patent ↗According to one embodiment, a video display apparatus includes a video reception module, a resolution processing module, and a notification module. The video reception module receives a video signal of a first resolution from an external apparatus. The resolution processing module generates a video signal of a second resolution higher than the first resolution by creating new pixel values from the video signal of the first resolution. The notification module transmits a notification indicating that the video display apparatus comprises the resolution processing module to the external apparatus.
1. A video display apparatus comprising:
a video reception module configured to receive a video signal of a first resolution from an external video reproduction apparatus, the video signal having been subjected to sharpening processing;
a super-resolution processing module configured to execute super-resolution conversion processing of generating a video signal of a second resolution higher than the first resolution by estimating an original pixel value to increase the number of pixels included in the video signal of the first resolution;
a notification module configured to notify the external video reproduction apparatus that the video display apparatus comprises the super-resolution processing module; and
a control module configured to execute control for weakening an effect of the sharpening processing of the external video reproduction apparatus, compared to a case where the video display apparatus does not comprise the super-resolution processing module.
2. The video display apparatus of claim 1 , wherein the notification module is configured to notify that the video display apparatus comprises the super-resolution processing module, in response to connection of the external video reproduction apparatus.
3. A video display apparatus comprising:
a video reception module configured to receive a video signal of a first resolution from an external video reproduction apparatus;
a super-resolution processing module configured to execute super-resolution conversion processing for generating a video signal of a second resolution higher than the first resolution by estimating an original pixel value to increase the number of pixels included in the video signal of the first resolution;
an information reception module configured to receive information indicating whether or not the external video reproduction apparatus comprises a function of executing sharpening processing; and
a control signal output module configured to supply the external video reproduction apparatus with a control signal for weakening an effect of the sharpening processing of the external video reproduction apparatus, compared to a case where the video display apparatus does not comprise the super-resolution processing module, when the information indicates that the external video reproduction apparatus comprises the function of executing the sharpening processing.
4. The video display apparatus of claim 3 , wherein the information reception module is configured to receive the information in response to connection of the external video reproduction apparatus.
5. The video display apparatus of claim 4 , wherein the control signal output module is configured to output the control signal in response to reception of information indicating that the external video reproduction apparatus comprises the function of executing the sharpening processing.
6. A video display method comprising:
receiving a video signal of a first resolution from an external video reproduction apparatus, the video signal having been subjected to sharpening processing;
executing super-resolution conversion processing for generating a video signal of a second resolution higher than the first resolution by estimating an original pixel value to increase the number of pixels included in the video signal of the first resolution;
notifying the external video reproduction apparatus that a function of the super-resolution conversion processing is included; and
executing control for weakening an effect of the sharpening processing of the external video reproduction apparatus, compared to a case where the super-resolution conversion processing is not executed.
7. The video display method of claim 6 , wherein the notifying comprising notifying that the function of the super-resolution conversion processing is included, in response to connection of the external video reproduction apparatus.
8. A video reproduction apparatus comprising:
a sharpening module configured to subject a video signal to sharpening processing;
a video output module configured to supply an external video reproduction apparatus with the video signal subjected to the sharpening processing;
an information reception module configured to receive information indicating whether or not the external video reproduction apparatus comprises a function of executing super-resolution conversion processing; and
a control module configured to execute control for weakening an effect of the sharpening processing compared to a case where the external video reproduction apparatus does not comprise a function of executing super-resolution conversion processing, when the information indicates that the external video reproduction apparatus comprises the function of executing the super-resolution conversion processing.
