Control device
First Claim
1. A control device comprising:
- a touch input device that has a manipulation surface adapted to receive a touch manipulation made by a finger of a user, and detects and outputs an input location of the touch manipulation;
an imaging device that has a photographing range having one-to-one coordinate relationship to the manipulation surface, and captures an image of a hand of the user getting access to the manipulation surface;
a fingertip specifying section that specifies a fingertip of the hand based on data of the image of the hand;
a display device that includes a display screen having one-to-one coordinate relationship to the photographing range and the manipulation surface;
a pointer image display control section that causes the display device to display a pointer image on the display screen, the pointer image pointing to a place corresponding to the fingertip;
a selection reception region setting section that sets a selection reception region on the display screen so that the selection reception region is located at a predetermined place on the display screen;
a move target image selection section that switches a move target image prepared on the selection reception region into a selected state when the touch input device detects that the touch manipulation is performed at the input location corresponds to the move target image item; and
an image movement display section that(i) detects a target fingertip, which is the fingertip that makes the touch manipulation at the input location corresponding to the move target image item,(ii) causes the display device to display the move target image in the selected state and the pointer image at a place corresponding to position of the target fingertip, and(iii) causes the move target image in the selected state and the pointer image to move together on the display screen in response to movement of the target fingertip in the photographing range, in such manner that a trajectory of movement of the selected move target image and the pointer image corresponds to a trajectory of the movement of the target fingertip.

Abstract
There is provided a control device for an in-vehicle electronic apparatus. The control device includes: a manipulation input element that has a manipulation input region having a predetermined area; an imaging device that has a photographing range covering the manipulation input region, and that captures an image including a hand image region representative of the hand; a hand image region identification section that identifies the hand image region in the image; an area ratio calculation section that calculates a value of hand image area ratio, which is area ratio of the hand image region to the manipulation input region; and an operation input information generation section that generates and outputs operation input information based on the calculated value of the hand image area ratio and a manipulation state of the manipulation input region, the operation input information being directed to the in-vehicle electronic apparatus.

20. A control device for a user to operate an in-vehicle electronic apparatus in a vehicle by manipulating the control device, the control device comprising:
-
a manipulation input element that is located so as to be within reach of the user who is sitting in a seat of the vehicle, and that has a manipulation input region having a predetermined area; an imaging device that has a photographing range covering the manipulation input region, and that captures an image including a hand image region representative of the hand of the user getting access to the manipulation input element; a hand image region identification section that identifies the hand image region in the image; an area ratio calculation section that calculates a value of hand image area ratio, which is area ratio of the hand image region to the manipulation input region; and an operation input information generation section that generates and outputs operation input information based on the calculated value of the hand image area ratio and a manipulation state of the manipulation input region, the operation input information being directed to the in-vehicle electronic apparatus. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
