Abstract
A display includes: a frame-rate conversion section being configured to be capable of changing a frame-rate conversion ratio having a value of 1 or more, the frame-rate conversion section converting a frame rate of an image signal at the frame-rate conversion ratio being set; and a display section displaying an image having undergone frame rate conversion.
Claims18
A display comprising:
- a frame-rate conversion section being configured to be capable of changing a frame-rate conversion ratio having a value of 1 or more, the frame-rate conversion section converting a frame rate of an image signal at the frame-rate conversion ratio being set;
- a display section displaying an image having undergone frame rate conversion;
- wherein the frame-rate conversion section outputs a signal portion related to each frame image after frame rate conversion, in a fixed period shorter than a frame period of an original frame image supplied by the image signal;
- wherein the frame-rate conversion section includes;
- a first conversion section converting a frame rate at a fixed first conversion ratio greater than 1;
- and
- a second conversion section converting a frame rate at a second conversion ratio having a value of 1 or less, by selectively masking a part of a second image signal for every frame image, the second image signal being supplied from the first conversion section;
- wherein the first conversion section further generates a frame-identification signal that identifies each frame image included in an image signal to be outputted, and
- wherein the second conversion section selectively masks a signal portion related to each frame image, based on the frame-identification signal.

A display method comprising:
- changing a frame-rate conversion ratio having a value of 1 or more, and converting a frame rate of an image signal at the frame-rate conversion ratio being set;
- displaying an image having undergone frame rate conversion;
- outputting a signal portion related to each frame image after frame rate conversion, in a fixed period shorter than a frame period of an original frame image supplied by the image signal;
- wherein the converting includes:
- a first converting that converts a frame rate at a fixed first conversion ratio greater than 1;
- and
- a second converting that converts a frame rate at a second conversion ratio having a value of 1 or less, by selectively masking a part of a second image signal for every frame image, the second image signal being supplied from the first converting;
- wherein the first converting further generates a frame-identification signal that identifies each frame image included in an image signal to be outputted, and
- wherein the second converting selectively masks a signal portion related to each frame image, based on the frame-identification signal.
