DEVICE FOR TRACKING ADJUSTMENT AND TRACKING ADJUSTMENT METHOD

摘要

A device for tracking adjustment comprising a zoom instruction input device, a focus instruction input device, a tracking instruction input device, an image signal obtaining device, a determining device which determines whether a state is a first adjustment state in which the zoom lens is set by the zoom instruction input device at a position on a tele side and the focus lens is moved by the focus instruction input device or a second adjustment state in which the zoom lens is set by the zoom instruction input device at a position on a wide side and the tracking lens is moved by the tracking instruction input device, an area setting device, an evaluation value generating device, and a display device, wherein the determining device determines whether the state is the first adjustment state or the second adjustment state based on the image signal obtained from the camera device.

1. A device for tracking adjustment comprising:
a zoom instruction input device to which an instruction for moving a zoom lens movable to change a focal length is inputted; a focus instruction input device to which an instruction for moving a focus lens movable to focus on a subject is inputted; a tracking instruction input device to which an instruction for moving a tracking lens movable to change a position of an image plane is inputted; an image signal obtaining device which obtains an image signal from a camera device having a lens device mounted thereon, the camera device having the zoom lens, the focus lens, and the tracking lens; a determining device which determines whether a state is a first adjustment state in which the zoom lens is set by the zoom instruction input device at a position on a tele side and the focus lens is moved by the focus instruction input device or a second adjustment state in which the zoom lens is set by the zoom instruction input device at a position on a wide side and the tracking lens is moved by the tracking instruction input device; an area setting device which sets a detection area for detecting a focus state of the lens device with respect to the image signal obtained by the image signal obtaining device, the area setting device switching a size of the detection area between the first adjustment state and the second adjustment state based on the determination result of the determining device; an evaluation value generating device which generates an evaluation value indicating the focus state of the lens device from the image signal obtained by the image signal obtaining device, the evaluation value generating device generating the evaluation value within the detection area set by the area setting device in an entire screen region of the image signal; and a display device which displays the evaluation value generated by the evaluation value generating device, wherein the determining device determines whether the state is the first adjustment state or the second adjustment state based on the image signal obtained from the camera device.
