Abstract

A display includes: a display section; and a display driving section driving the display section based on a first image data set and a second image data set that alternate with each other. The display driving section drives the display section by performing a first scan with use of a first block as a driving unit in accordance with the first image data set and a second scan with use of a second block as a driving unit in accordance with the second image data set. The first block is composed of a plurality of consecutive pixel lines, and the second block is composed of a plurality of consecutive pixel lines and is different from the first block.

Claims (41)

1. A display, comprising:

a display section;

a display driving section driving the display section based on a first image data set and a second image data set that alternate with each other; and

an image generating section including a frame rate conversion section that performs a frame rate conversion based on an input image signal and generating the first image data set and the second image data set based on image data subjected to the frame rate conversion, wherein the image input signal is a progressive signal,

wherein the display driving section drives the display section by performing a first scan with use of a first block as a driving unit in accordance with the first image data set and a second scan with use of a second block as a driving unit in accordance with the second image data set, the first block being composed of a plurality of consecutive pixel lines, and the second block being composed of a plurality of consecutive pixel lines and being different from the first block.

2. The display according to claim 1 , wherein

the image generating section generates a determination signal indicating whether either the first image data set or the second image data set is generated, and

the display driving section selectively performs the first scan or the second scan based on the determination signal.

3. The display according to claim 1 , wherein

the image generating section further includes an image separation section,

the frame rate conversion section generates a third image data set and a fourth image data set that alternate with each other, by performing the frame rate conversion based on the progressive signal, and

the image separation section generates the first image data set by separating odd-numbered line image data based on the third image data set, while generating the second image data set by separating even-numbered line image data based on the fourth image data set.

4. The display according to claim 3 , wherein

the image generating section further includes a filter performing smoothing among pixel lines for each of the third image data set and the fourth image data set, and

the image separation section generates the first image data set based on the smoothed third image data set, while generating the second image data set based on the smoothed fourth image data set.

5. The display according to claim 3 , wherein each of the third image data set and the fourth image data set is composed of pixel data equivalent in quantity to the number of pixels in the display section.

6. The display according to claim 3 , further comprising a conversion section converting an interlace signal into a progressive signal,

wherein the input image signal is the progressive signal converted by the conversion section.

7. The display according to claim 1 , wherein

the input image signal includes a series of input image data sets,

the image generating section further includes an image separation section, the image separation section generating an odd-numbered line image data set by separating odd-numbered line image data and generating an even-numbered line image data set by separating even-numbered line image data, based on each of the series of input image data sets, and

the frame rate conversion section uses one of the odd-numbered line image data set and the even-numbered line image data set as the first data set, and generates the second image data set by performing interpolation processing on a time axis on the other of the odd-numbered line image data set and the even-numbered line image data set.

8. The display according to claim 7 , wherein

the image generating section further includes a filter performing smoothing among pixel lines for each of a series of the input image data set, and

the image separation section generates the odd-numbered line image data set and the even-numbered line image data set based on each of the series of input image data sets that is smoothed.

9. The display according to claim 7 , wherein

the image generating section generates a determination signal indicating whether either the first image data set or the second image data set is generated, and

the frame rate conversion section performs the frame rate conversion based on the determination signal.

10. The display according to claim 1 , further comprising an image processing section performing predetermined image processing on the first image data set and the second image data set,

wherein the display driving section drives the display section based on the first image data set subjected to the image processing and the second image data set subjected to the image processing.

11. The display according to claim 1 , wherein each of the first image data set and the second image data set is composed of pixel data equivalent in quantity to half of the number of the pixels in the display section.

12. The display according to claim 1 , wherein the first block and the second block are both composed of two pixel lines, and

the first block is shifted from the second block by a single line.

13. The display according to claim 1 , wherein the display section is an EL display section.

14. An image processing unit, comprising:

a display driving section driving a display section by performing a first scan with use of a first block as a driving unit in accordance with a first image data set and a second scan with use of a second block as a driving unit in accordance with a second image data set, the first block being composed of a plurality of consecutive pixel lines, the second block being composed of a plurality of consecutive pixel lines and being different from the first block, and the first image data set and the second image data set alternating with each other; and

an image generating section including a frame rate conversion section that performs a frame rate conversion based on an input image signal and generating the first image data set and the second image data set based on image data subjected to the frame rate conversion, wherein the image input signal is a progressive signal.

15. A display method, comprising:

preparing a first image data set and a second image data set alternating with each other; and

driving a display section by performing a first scan with use of a first block as a driving unit in accordance with the first image data set and a second scan with use of a second block as a driving unit in accordance with the second image data set, the first block being composed of a plurality of consecutive pixel lines, and the second block being composed of a plurality of consecutive pixel lines and being different from the first block; and

generating an image by performing a frame rate conversion based on an input image signal and generating the first image data set and the second image data set based on image data subjected to the frame rate conversion, wherein the image input signal is a progressive signal.
