Abstract

An image processing device includes an image processor. The image processor performs an image processing on an image signal on a basis of a result of detection of a contact condition in which a user makes contact with a display section. The image processing includes an enhancement processing performed on the image signal in accordance with the contact condition.

Claims

1. An image processing device, comprising an image processor that performs an image processing on an image signal on a basis of a result of detection of a contact condition in which a user makes contact with a display section, the image processing including an enhancement processing performed on the image signal in accordance with the contact condition.

2. The image processing device according to claim 1, wherein the enhancement processing is a processing that enhances, in accordance with the contact condition, one or more of a three-dimensional effect, luminance contrast, and chroma contrast of an image expressed on a basis of the image signal.

3. The image processing device according to claim 2, wherein

the enhancement processing includes at least the processing that enhances the three-dimensional effect, and

the image processor further performs a processing that compensates for decreased resolution of the image due to the processing that enhances the three-dimensional effect.

4. The image processing device according to claim 1, wherein the image processor performs the enhancement processing utilizing a result of detection of a stress that is generated on the display section due to the contact made by the user with the display section.

5. The image processing device according to claim 4, further comprising an analyzer that performs analysis of the result of the detection of the contact condition on a basis of the stress detected by a stress sensor, and supplies a result of the analysis to the image processer.

6. The image processing device according to claim 5, wherein

the analyzer generates stress distribution in the display section on the basis of the stress detected by the stress sensor, and

the analyzer performs analysis on each of a type and contact intensity of the contact condition on a basis of the generated stress distribution, and supplies a result of the analysis to the image processor, the type and the contact intensity of the contact condition being included in the result of the detection of the contact condition.

7. The image processing device according to claim 6, wherein

the analyzer determines each of a contact position at which the user makes the contact with the display section, the contact intensity, and a stress gradient in the display section, on the basis of the stress distribution, and

the analyzer determines the type of the contact condition on a basis of the contact position and the stress gradient.

8. The image processing device according to claim 7, wherein

the analyzer determines each of a coordinate of a local maximum value in the stress distribution, magnitude of the local maximum value in the stress distribution, and low frequency component distribution of the stress in the display section, on the basis of the stress distribution,

the analyzer determines the contact position on a basis of the coordinate of the local maximum value,

the analyzer determines the contact intensity on a basis of the magnitude of the local maximum value, and

the analyzer determines the stress gradient on a basis of the coordinate of the local maximum value and the low frequency component distribution of the stress.
