On-board camera apparatus
First Claim
1. An on-board camera apparatus comprising:
- a camera module that captures an image of an area ahead of an own vehicle, generates, as captured images, a plurality of linear images in which a relationship between luminance and an output pixel value is fixed, and further generates, based on the linear images, high dynamic range images in which a relationship between luminance and an output pixel value differs depending on a luminance region, under a predetermined imaging mode, the high dynamic range images being used for image recognition of an illumination state of a lamp on a preceding vehicle, the linear images being used for image recognition of a pedestrian, another vehicle, or a white line;
a control circuit board that enables a plurality of types of driving-related processes based on the captured images to be performed, and enables the camera module to perform either of a linear mode and a high dynamic range mode in a setting in which a plurality of images are captured at a plurality of exposures that are performed at a single imaging timing, the linear mode being a mode in which the linear images are generated without combining the plurality of captured images, the high dynamic range mode being a mode in which the high dynamic range images are generated by combining the plurality of captured images;
a housing that houses the camera module and the control circuit board;
a bracket that is a member for fixing the housing to a front windshield of the own vehicle, and in which an opening is formed such that the housing and the front windshield oppose each other in a state in which the housing is fixed to the front windshield by the member; and
a hood that is arranged so as to cover the camera module.

Abstract
An on-board camera apparatus includes a camera module, a control circuit board, a housing, a bracket, and a hood. The housing houses the camera module and the control circuit board. The bracket fixes the housing to a front windshield of the own vehicle. The hood is arranged so as to cover the camera module. The camera module captures an image of an area ahead of an own vehicle. As captured images, the camera module generates a plurality of linear images in which a relationship between luminance and an output pixel value is fixed. Based on the linear images, the camera module further generates high dynamic range images in which a relationship between luminance and an output pixel value differs depending on a luminance region, under a predetermined imaging mode. The control circuit board enables a plurality of types of driving-related processes based on the captured images to be performed.

11. A control method for an on-board camera apparatus, the on-board camera apparatus comprising:
- a camera module;
a control circuit board;
a housing that houses the camera module and the control circuit board;
a bracket that is a member for fixing the housing to a front windshield of the own vehicle, and in which an opening is formed such that the housing and the front windshield oppose each other in a state in which the housing is fixed to the front windshield by the member; and
