Operating input device for reducing input error
First Claim
1. An input device receiving a first signal from a touch panel indicating an actual input position of a finger press and a second signal from an imaging device for capturing an image of the finger on the touch panel, the first and second signal used to reduce input errors based on visual feedback provided on a display, the input device comprising:
- a finger area extraction unit for extracting a finger area image from an image captured by the imaging device;
a fingertip position detection unit for detecting a fingertip position based on the finger area image; and
an image synthesis unit for synthesizing the finger area image and superimposing the finger area image on a menu image, the finger area image and the menu image displayed such that both the finger area image and the menu image are viewable on the display,wherein the fingertip position detection unit obtains a fingertip area image as a difference between the finger area image and a shifted image obtained by shifting the finger area image toward the base of fingers and extracts a fingertip position relative to the fingertip area image.

Abstract
An operating input device is provided in which input errors can be prevented. A finger area image is extracted from an image captured by a camera. A fingertip area is extracted from a difference image generated between the finger area image and a shifted image. A fingertip position is detected from the fingertip area based on a center of mass. A semitransparent fingertip image is superimposed on the menu image. Manual operation buttons coinciding with fingertip positions are displayed in an emphasized manner. An actual position of a finger press is shifted to coincide with a manual operation button position and the manual operation button is considered to be pressed.

12. An operating input device receiving a first signal from a touch panel for indicating an actual input position of a finger press and a second signal from an imaging device for capturing an image of a finger on the touch panel, the operating input device providing operating input associated with a menu displayed on a display device based on the first signal from the touch panel, the operating input device comprising:
-
a finger area extraction unit for extracting a finger area image from an image captured by the imaging device; a fingertip position detection unit for detecting a fingertip position based on the finger area image; and an image synthesis unit for synthesizing the finger area image and superimposing the finger area image on a menu image, the finger area image and the menu image displayed such that both the finger area image and the menu image are viewable on the display, wherein when the finger press is detected, first coordinates associated with the actual input position are corrected to correspond to second coordinates associated with the fingertip position in proximity to the actual input position. - View Dependent Claims (13, 14)

15. An operating input device receiving a first signal from a touch panel for indicating an actual input position of a finger press and a second signal from an imaging device for capturing an image of a finger on the touch panel, the operating input device providing operating input associated with a menu displayed on a display device based on the first signal from the touch panel, the operating input device comprising:
-
a finger area extraction unit for extracting a finger area image from an image captured by the imaging device; a fingertip position detection unit for detecting a fingertip position based on the finger area image; and an image synthesis unit for synthesizing the finger area image and superimposing the finger area image on a menu image, the finger area image and the menu image displayed such that both the finger area image and the menu image are viewable on the display, wherein when the distance between a manual operation button and the fingertip position is within a predetermined range and when the finger press is detected, processing is carried out with the manual operation button considered to have been operated.
