Problems solved by technology

[0005] On the other hand, there is also a countermeasure of changing the orientation of the imaging device when the vehicle is stopped (for example, pointing the imaging device upward so that the signal lights above can be seen), but the impact of changing the orientation is large, and the durability of the device is also reduced. Difference
In addition, there is a technical problem that the electric power required to drive the device is large.

[0018] (1) Device configuration

[0019] First, refer to figure 1 as well as figure 2 The configuration of the imaging device according to the first embodiment will be described. figure 1 It is a block diagram showing the configuration of the imaging device according to the first embodiment. figure 2 It is a perspective view showing the states before and after the movement of the imaging sensor in the imaging device according to the first embodiment.

[0020] Such as figure 1 As shown, the imaging device 100 according to the first embodiment is configured to include a lens 110 , an imaging sensor 120 , an image processing unit 130 , an actuator 140 , a sensor control unit 150 , and a vehicle speed determination unit 160 .

[0021] The imaging device 100 is installed, for example, around a front window of a vehicle, and captures an image of the front of the vehicle. When shooting, a signal corresponding to light incident from the lens 100 is output from the imaging senso...

[0042] Next, the imaging device 100 according to the second embodiment will be described. However, the second embodiment differs from the above-mentioned first embodiment only in a part of the configuration and operation, and the other parts are substantially the same. Therefore, parts different from those of the first embodiment already described will be described in detail below, and descriptions of overlapping parts will be appropriately omitted.

[0043] (1) Device configuration

[0044] First, refer to Figure 7 as well as Figure 8 The configuration of the imaging device 100 according to the second embodiment will be described. Figure 7 It is a perspective view showing the states before and after the movement of the imaging sensor in the imaging device according to the second embodiment. Figure 8 It is a side view showing the driving direction of the imaging sensor in the imaging device according to the second embodiment. In addition, in Figure 7 as well as Fi...

Abstract

The present invention provides an imaging apparatus that captures a signal light when the vehicle is stopped in the imaging apparatus that photographs a scene ahead of a vehicle. The imaging apparatus100 is configured to photograph an image of a scene ahead of a vehicle 10, and is provided with: an actuator 140 configured to adjust a relative position of an imaging sensor 120 with respect to a lens 110; and a controller 150 configured to control the actuator in such a manner that light that enters from above the lens enters the imaging sensor when a speed of the vehicle is less than a predetermined speed, in comparison with when the speed of the vehicle is greater than the predetermined speed.

Description

technical field [0001] The present invention relates to the technical field of imaging devices capable of capturing images ahead of a vehicle. Background technique [0002] In such an imaging device, since the imaging direction is fixed, when the vehicle stops due to a signal, the signal light at a high position may deviate from the imaging range when viewed from the vehicle. As a countermeasure to avoid this situation, for example, when the vehicle stops due to a signal, there is disclosed a technique of stopping the vehicle at a recognition limit distance at which the signal light can be recognized by an imaging device (see Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-146284 [0004] However, there is a possibility that the recognition limit distance described in the above-mentioned Patent Document 1 is set at a place far before the stop line (for example, several meters). In this case, the vehicle will stop at a positio...
