Abstract
According to one embodiment, an image processor comprises an image converter and a controller. The image converter is configured to convert a first video signal of a first resolution to a second video signal of a second resolution higher than the first resolution. The conversion is based on a parameter indicating a ratio of high-frequency component pixels of the first video signal to be interpolated and pixels forming the first video signal to be interpolated. The controller is configured to change the parameter based on a type of broadcast wave of the first video signal. The type of broadcast wave may include, but is not limited or restricted to satellite broadcasting or terrestrial broadcasting.
Claims23
An image processor comprising:
- an image converter configured to convert a first video signal of a first resolution to a second video signal of a second resolution higher than the first resolution using a parameter having a numeric value indicating a ratio of high-frequency component pixels of the first video signal to be interpolated and pixels forming the first video signal to be interpolated;
- and
- a controller configured to change the parameter based on a type of broadcast wave of the first video signal, the type of broadcast wave including at least one of (i) satellite broadcasting and (ii) terrestrial broadcasting.
An image processing method comprising:
- converting a first video signal of a first resolution to a second video signal of a second resolution higher than the first resolution using a parameter having a numeric value indicating a ratio of high-frequency component pixels of the first video signal and pixels forming the first video signal;
- and
- changing the parameter based on a type of broadcast wave of the first video signal, the type of broadcast wave including at least one of (i) satellite broadcasting and (ii) terrestrial broadcasting.
An image processor comprising:
- a resolution increase module configured to perform super-resolution processing by increasing a first resolution of a first video signal to a second resolution of a second video signal using a super-resolution level that indicates an intensity of a super-resolution conversion as a numeric value;
- and
- a controller configured to change the super-resolution level based on a type of broadcasting of the first video signal, the type of broadcasting including at least one of (i) satellite broadcasting and (ii) terrestrial broadcasting.
An image processor comprising:
- a resolution increase module configured to perform super-resolution processing by increasing a first resolution of a first video signal to a second resolution of a second video signal using a parameter having a numeric value indicating a ratio of high-frequency component pixels of the first video signal to be interpolated and pixels forming the first video signal to be interpolated;
- and
- a controller configured to change a super-resolution level indicating an intensity of the super-resolution processing performed by the resolution increase module based on a type of broadcast wave of the first video signal, the type of broadcast wave including at least one of (i) satellite broadcasting and (ii) terrestrial broadcasting.
