Abstract

A video signal output device is disclosed. The device includes: a video signal generation section that generates an output video signal for screen display; an operation input section that detects a physical touch position and a pressure with respect to an input surface, and in accordance with a detection result, generates information about the touch position and information about the pressure for use each as an operation signal; and a control section that controls, in accordance with the operation signals coming from the operation input section, the video signal generation section to change display contents of the output video signal. In the device, while the output video signal for list display of a plurality of images is being generated, the information about the touch position and the information about the pressure are processed as the operation signal for image selection and the operation signal related to the images, respectively.

Claims

1. A video signal output device, comprising:

a video signal generation section that generates an output video signal for screen display;

an operation input section that detects a physical touch position and a pressure with respect to an input surface, and in accordance with a detection result, generates information about the touch position and information about the pressure for use each as an operation signal; and

a control section that controls, in accordance with the operation signals coming from the operation input section, the video signal generation section to change display contents of the output video signal, wherein

while the video signal generation section is generating the output video signal for list display of a plurality of images, the control section processes the information about the touch position as the operation signal for image selection, and processes the information about the pressure as the operation signal related to any of the images being a result of selection.

2. The video signal output device according to claim 1, wherein

the operation input section also detects a physical touch area with respect to the input surface, and in accordance with a detection result, generates, for use as the operation signal, information about the touch area together with the information about the touch position and the information about the pressure, and

while the video signal generation section is generating the output video signal for list display of a plurality of images, the control section processes the information about the pressure and the information about the touch area each as the operation signal related to the image being the result of selection.

3. The video signal output device according to claim 1, wherein while the video signal generation section is generating the output video signal for list display of a plurality of images, the control section processes the information about the pressure as the operation signal for a command of increasing a size of the image being the result of selection.

4. The video signal output device according to claim 1, wherein while the video signal generation section is generating the output video signal for list display of a plurality of thumbnail images in the unit of predetermined video data, the control section processes the information about the pressure and the information about the touch area each as the operation signal related to display of divided thumbnail images being a result of dividing any of the units of video data corresponding to any of the thumbnail images being a result of selection.

5. An operation input processing method, comprising the steps of:

detecting a physical touch position and a pressure with respect to an input surface of an operation input section;

processing information about the touch position for use as an operation signal for image selection on a screen on which a plurality of images are displayed in the form of a list; and

processing information about the pressure for use as another operation signal related to any of the images being a result of selection.
