Operator identifying device
First Claim
1. An operator identifying device for a vehicle with an operating section located between a driver'"'"'s seat and a non-driver'"'"'s seat to be operated from the driver'"'"'s seat and the non-driver'"'"'s seat, comprising:
- a photographing section configured and arranged to obtain image data of a prescribed region encompassing at least the operating section and at least one of a hand of a driver and a hand of a non-driver when the at least one of the hand of the driver and the hand of the non-driver is extended toward the operating section; and
an image processing section configured to extract a hand image that represents the at least one of the hand of the driver and the hand of the non-driver from the image data by applying binary processing to the image data, to find a center of gravity of the hand image, and to determine an operator of the operating section based on whether the center of gravity is on a driver'"'"'s seat side or a non-driver'"'"'s seat side of a reference line that divides the image data into the driver'"'"'s seat side and the non-driver'"'"'s seat side when the at least one of the hand of the driver and the hand of the non-driver has been extended into the prescribed region, the image processing section being further configured to output an identification result to control an operation of a vehicle apparatus based on the identification result.

Abstract
An operator identifying device for a vehicle with an operating section located between driver'"'"'s and non-driver'"'"'s seats includes a photographing section and an image processing section. The photographing section is configured to obtain image data of a prescribed region encompassing the operating section and at least one of hands of a driver and a non-driver when the at least one of the hands is extended toward the operating section. The image processing section is configured to process the image data to determine whether at least one of the driver and the non-driver is an operator of the operating section. Moreover, an onboard apparatus is provided with the operator identifying device, an operating section and a control section. The control section is configured to control an operation of the onboard apparatus based on an operator identification result of the operator identifying device.

1. An operator identifying device for a vehicle with an operating section located between a driver'"'"'s seat and a non-driver'"'"'s seat to be operated from the driver'"'"'s seat and the non-driver'"'"'s seat, comprising:
-
a photographing section configured and arranged to obtain image data of a prescribed region encompassing at least the operating section and at least one of a hand of a driver and a hand of a non-driver when the at least one of the hand of the driver and the hand of the non-driver is extended toward the operating section; and an image processing section configured to extract a hand image that represents the at least one of the hand of the driver and the hand of the non-driver from the image data by applying binary processing to the image data, to find a center of gravity of the hand image, and to determine an operator of the operating section based on whether the center of gravity is on a driver'"'"'s seat side or a non-driver'"'"'s seat side of a reference line that divides the image data into the driver'"'"'s seat side and the non-driver'"'"'s seat side when the at least one of the hand of the driver and the hand of the non-driver has been extended into the prescribed region, the image processing section being further configured to output an identification result to control an operation of a vehicle apparatus based on the identification result. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. An onboard apparatus comprising:
-
an operating section configured to be positioned in a front section of a vehicle between a driver'"'"'s seat and a non-driver'"'"'s seat such that the operating section is operable from the driver'"'"'s seat and the non-driver'"'"'s seat; an operator identifying device including a photographing section configured and arranged to obtain image data of a prescribed region encompassing at least the operating section and at least one of a hand of a driver and a hand of a non-driver when the at least one of the hand of the driver and the hand of the non-driver is extended toward the operating section, and an image processing section configured to extract a hand image that represents the at least one of the hand of the driver and the hand of the non-driver from the image data by applying binary processing to the image data, to find a center of gravity of the hand image, and to determine an operator of the operating section based on whether the center of gravity is on a driver'"'"'s seat side or a non-driver'"'"'s seat side of a reference line that divides the image data into the driver'"'"'s seat side and the non-driver'"'"'s seat side when the at least one of the hand of the driver and the hand of the non-driver has been extended into the prescribed region; and a control section configured to control an operation of the onboard apparatus based on an operator identification result performed by the operator identifying device. - View Dependent Claims (11, 12, 13, 14)

15. An operator identifying device for a vehicle with an operating section located between a driver'"'"'s seat and a non-driver'"'"'s seat to be operated from the driver'"'"'s seat and the non-driver'"'"'s seat, comprising:
-
photographing means for obtaining image data of a prescribed region encompassing at least the operating section and at least one of a hand of a driver and a hand of a non-driver when the at least one of the hand of the driver and the hand of the non-driver is extended toward the operating section; and image processing means for extracting a hand image that represents the at least one of the hand of the driver and the hand of the non-driver from the image data by applying binary processing to the image data, for finding a center of gravity of the hand image, and for determining an operator of the operating section based on whether the center of gravity is on a driver'"'"'s seat side or a non-driver'"'"'s seat side of a reference line that divides the image data into the driver'"'"'s seat side and the non-driver'"'"'s seat side when at least one of the hands of the driver and the non-driver has been extended into the prescribed region, and for outputting an identification result to control an operation of a vehicle apparatus based on the identification result.

16. A method of identifying an operator of an operating section located between a driver'"'"'s seat and a non-driver'"'"'s seat of a vehicle to be operated from the driver'"'"'s seat and the non-driver'"'"'s seat, comprising:
-
obtaining image data of a prescribed region encompassing the operating section and at least one of a hand of a driver and a hand of a non-driver when the at least one of the hand of the driver and the hand of the non-driver is extended toward the operating section; extracting a hand image that represents the at least one of the hand of the driver and the hand of the non-driver from the image data by applying binary processing to the image data when at least one of the hand of the driver and the hand of the non-driver has been extended into the prescribed region; finding a center of gravity of the hand image; determining an operator of the operating section based on whether the center of gravity is on a driver'"'"'s seat side or a non-driver'"'"'s seat side of a reference line that divides the image data into the driver'"'"'s seat side and the non-driver'"'"'s seat side; and outputting an identification result to control an operation of a vehicle apparatus based on the identification result.
