Problems solved by technology

However, in-vehicle cameras often use wide-angle cameras, and the effect of distortion will be more pronounced on the outer periphery.
In addition, even if the distortion of the camera itself is small, when the camera is built into a headlight or rear light, etc., distortion will be introduced by an additional optical system such as an outer lens.

Embodiment approach 11

[0064] figure 1 It is a block diagram of the imaging system 100 of Embodiment 1.1. The photography system 100 includes a camera 110 and an image processing device 120 . The camera 110 is built in, for example, the lamp body 12 of a vehicle lamp 10 such as a headlight of an automobile. In addition to the camera 110 , the vehicular lamp 10 includes light sources for the high beam 16 and the low beam 18 , their lighting circuits, a radiator, and the like.

[0065] The camera 110 takes pictures of the front of the camera through the outer lens 14 . In addition to the distortion inherent in the camera 110, the outer lens 14 introduces additional distortion. The type of the camera 110 is not limited, and various cameras such as a visible light camera, an infrared camera, and a TOF camera can be used.

[0066] The image processing device 120 generates information (parameters or functions) necessary for correcting distortion including the influence of the camera 110 and the outer ...

Embodiment approach 12

[0085] Figure 6 It is a block diagram of the imaging system 200 of Embodiment 1.2. The imaging system 200 may also be incorporated in the vehicle lamp 10 as in Embodiment 1.1. The photography system 200 includes a camera 210 and an image processing device 220 . Similar to Embodiment 1.1, the image processing device 220 generates information (parameters or functions) necessary for correcting distortion including the effects of the camera 210 and the outer lens 14 based on the output image IMG1 of the camera 210 . Then, the camera image IMG1 is corrected based on the generated information, and the corrected image IMG2 is output.

[0086]The image processing device 220 includes a distortion correction execution unit 222 and a correction characteristic acquisition unit 230 . The correction characteristic acquisition unit 230 detects the reference object OBJ whose true shape is known from the camera image IMG1 REF like. Then, based on the real shape S of the image of the refe...

Embodiment approach 2

[0093] (Summary of Embodiment 2)

[0094] One embodiment disclosed in this specification relates to a vehicle imaging system. The photography system includes: a camera; and an image processing device that processes an output image of the camera. When the current frame of the output image contains a foreign object, the image processing device searches out the background image covered by the foreign object from past frames, and pastes the background image on the foreign object area where the foreign object exists in the current frame.

[0095] In an in-vehicle photography system, the camera moves along with the movement of the vehicle, so the image of the object included in the camera image continues to move. On the other hand, when a foreign object is attached, the foreign object tends to stay in the same position continuously, or to move more slowly than the object image. That is, currently, an object image present in a foreign object area covered by a foreign object existed...

Abstract

A photographing system (100) comprises a camera (110) and an image processing device (120). The image processing device (120) tracks an object image contained in an output image (IMG1) of the camera (110), and acquires information for correcting distortion of the output image on the basis of variation in shape accompanying the movement of the object. The acquired information is then used to correct the output image.

Description

technical field [0001] The present invention relates to photography systems. Background technique [0002] In recent years, the installation of cameras in automobiles has been progressing. Cameras are used in various fields such as automatic driving, automatic control of light distribution of headlights, digital mirrors, and front view monitors or rear view monitors for covering blind spots. [0003] Such a camera is preferably capable of recording images as undistorted as possible. However, in-vehicle cameras often use wide-angle cameras, and the effect of distortion will be more noticeable on the outer periphery. In addition, even if the distortion of the camera itself is made small, distortion will be introduced by an additional optical system such as an outer lens (out lens) when the camera is built into a headlight or a rear light.
