Embodiment 1

[0026] The following will refer to figure 1 Embodiment 1 of the present invention is described. figure 1 is a diagram showing the configuration of the imaging device in Embodiment 1.

[0027] The imaging device 101 includes a movable unit 102, an imaging unit 103, a processing unit 104, and the like. The display unit 105 functions as a display section for displaying images. Here, the display unit 105 may be an external monitor or the like, or may be a display unit of a terminal of a PC, and is connected to the imaging device through a network.

[0028] The processing unit 104 may also be included in a terminal such as an external PC connected to the imaging device through a network. That is, the imaging apparatus in this example is not limited to an integrated system, but includes a system configured as a single body. The display unit 105 may be integrally formed with the imaging device.

[0029] When the display unit 105 is connected to a terminal such as a PC, shooting ...

Embodiment 2

[0079] Embodiment 2 of the present invention will be described below.

[0080] The following will refer to Figure 6 Example 2 is described. Figure 6 is a diagram showing the configuration of the imaging device in Example 2. despite using figure 1 The angle storage unit 106 and the angle correction value storage unit 107 in the imaging device are shown to determine the correction angle, but in this example, the movement is performed electrically. Therefore, the method for determining the correction angle is different from that of Embodiment 1.

[0081] exist Figure 6 Among them, the imaging unit 103 is driven by the driving unit 601 to perform panning / tilting and the like driving. Here, the drive unit 601 functions as a drive section for rotating the movable unit around a movable shaft. Although the drive unit includes a motor such as a DC motor, a stepping motor, and an ultrasonic motor, and rotates the drive shaft using a gear mechanism having gears or a belt, etc., ...

Embodiment 3

[0094] Embodiment 3 of the present invention will be described below. Figure 8 is a flow chart for describing the flow of operation of Embodiment 3.

[0095] Embodiment 3 shows control in an imaging device having various types of detection / sensing functions. Examples of the sensing function include various functions such as a function for detecting a human body, a function for detecting an intruder, a function for detecting removal of an object, and the like.

[0096] Although there are various detection methods for these functions, when an object image includes movement in a rotation direction, in some cases, false detection may or may not be caused. For example, in intrusion detection or the like that issues an alarm based on a judgment as to whether an intrusion has been made to a specific area, in some cases, when an entry to the area is made and when an exit from the area is made may be caused by an image Rotation of , is reversely recognized, and intrusion detection e...

Abstract

The invention provides an imaging device, a control method thereof, and a storage medium. In order to provide an imaging device capable of simply correcting unnecessary rotation of an image caused by rotation of a movable unit, the imaging device has the following configuration: an imaging unit configured to acquire an image; a movable unit configured to change a direction of the imaging unit by rotation of the movable unit about a predetermined axis; and at least one processor or circuit configured to function as a correction processing unit configured to correct the rotation angle of the image acquired by the imaging unit based on information about a relationship between the rotation angle about the axis and the rotation angle of the image acquired by the imaging unit. In this way, the rotation of the image caused by the rotation of the movable unit is corrected.

Description

technical field [0001] The present invention relates to an imaging device and the like, and particularly relates to an imaging device capable of changing the direction of an imaging unit. Background technique [0002] Among imaging devices including a plurality of imaging units, there is known a multi-lens machine in which if one rotation axis is rotated, the plurality of imaging units move or rotate in groups at the same time. In this multi-lens machine, the respective imaging units are arranged on a spherical surface, for example, and have a twisted positional relationship with respect to the rotation axis. Thus, as the axis of rotation rotates, the image has a rotational component about the optical axis. [0003] The distorted positional relationship mentioned here means that the direction of the vertical line passing through the center point of the rotating sphere on the rotation axis is not parallel to the direction of the optical axis of the imaging unit at the point ...
