This page provides information on dashcams equipped with a wide-angle view, allowing users to capture a broader perspective of their surroundings while driving.
A wide-angle view is essential in dashcams as it expands the field of vision, enabling a more comprehensive recording of the road ahead. With a wider view, users can capture not only what's happening directly in front of them but also potential hazards and incidents in the periphery. This feature is particularly useful in busy urban areas, intersections, and highway driving, where unexpected events can occur from various angles. A wider perspective ensures a more accurate and detailed visual account, enhancing driver safety and providing valuable evidence in case of accidents.
Designing dashcams with a wide-angle view poses certain technological challenges. Maintaining image clarity and reducing distortions at the edges of the frame can be a complex task. Wide-angle lenses often introduce barrel distortion, where straight lines at the edges of the image appear curved. Additionally, capturing a wider view requires higher resolution and adequate image processing power. Balancing these technical aspects without compromising image quality and overall performance is crucial in dashcam design.
Sony Group Corporation, 2023
Reducing complexity of camera systems in vehicles by using multiple cameras with optimized view angles. The cameras are mounted in a housing with one camera facing obliquely rearward and another facing forward or laterally. This allows capturing rear views without blind spots and forward/lateral views simultaneously using fewer cameras. The system can also have additional cameras with intermediate view angles. The images are displayed on a monitor, with the rear camera providing a standard rear view and the front/lateral camera providing supplemental views. External object recognition is performed on the forward/lateral view and visual effects are shown based on the recognition results. This avoids the need for multiple cameras with overlapping views.
JAGUAR LAND ROVER LIMITED, 2022
Camera assembly for vehicles that provides wider vertical field of view to image objects above the vehicle. The camera has an offset lens axis relative to the image sensor center. This allows the lens to capture more vertical pixels on the sensor due to the offset, effectively widening the vertical field of view compared to a centered lens. This enables the camera to see objects like tall road signs above the vehicle without needing a taller vehicle hood.
Robert Bosch GmbH, 2022
Method for displaying a realistic 3D model of a vehicle's surrounding area by harmonizing color information from multiple wide-angle camera views. The method uses a lattice structure to assign pixels from overlapping camera images. Color differences at lattice points are evaluated and weighted to determine a global color transformation. This transformation is then applied to adapt one camera view's colors to match the other view, providing a consistent appearance. The adapted images are used to create the 3D model with realistic color and brightness across views.
Panasonic Intellectual Property Management Co., Ltd., 2022
An imaging system for vehicles that provides a wide field of view while maintaining high resolution for critical areas. The system uses a single camera with an asymmetric imaging surface and optical system. The imaging surface has two regions - one with higher resolution than the other. The resolution of the center region is lower than the outer region. This allows capturing a wider field of view without increasing camera size. The lower resolution center region is offset horizontally and vertically from the view angle center. This provides a wider field of view while preserving critical resolution for important areas.
Sony Semiconductor Solutions Corporation, 2022
A vehicle-mounted camera that can capture both far and near views of the surroundings in a single camera for applications like rearview mirrors and parking assistance. The camera has a lens and an imaging device with a rectangular sensor. The sensor has two positions along the in-plane direction perpendicular to the lens axis. The optical axis passes through the first position. The second position is at the center. This allows the camera to capture a wide field of view with good resolution for far objects using the first position, and a close-in view with sufficient resolution for near objects using the second position.
DENSO CORPORATION, 2021
Compact camera module for vehicle windshield mounting that captures a wide angle view. The camera module includes a wide angle lens and a hood to block light outside the imaging target range. The hood design allows imaging the external environment while preventing bright light interference. The hood has an open top and side walls that extend from around the lens towards the windshield. The height of the side walls is set to avoid blocking the full angle of view.
JIANGXI LIANCHUANG ELECTRONIC CO., LTD., 2020
Wide-angle lens for vehicle cameras that enables high quality imaging and stability over a range of temperatures. The lens has a unique configuration of glass lenses that avoids the use of plastic.

Hyundai Autron Co., Ltd., 2020
A camera module for vehicles that can capture 360° views around the vehicle using multiple lenses mounted at different angles. The module has a movable image sensor that can be positioned to match each lens's view. This allows capturing 360° images using a single sensor instead of multiple fixed cameras. The sensor movement is guided by a mechanism inside the module. The images are processed by an external unit. This provides a compact and versatile camera system for vehicle surround view and blind spot monitoring applications.
DENSO CORPORATION, 2020
Camera module for vehicles to image the external environment for applications like advanced driving assistance. The camera uses a wide angle lens to capture a large field of view, but improves compactness and prevents interference with the driver's view. The lens has an asymmetric shape with a larger upper half to aim more upward. This way, it captures more overhead traffic signals without blocking the driver's view.

VALEO Schalter und Sensoren GmbH, 2017
Producing a larger image of a vehicle's surroundings by stitching together multiple partial images captured at different camera positions. The method involves recording a first partial image from a camera in one position, then capturing at least a second partial image from the same camera in a different position. The partial images, each covering the full camera field of view, are combined to form a larger composite image showing a wider area than any individual partial image. This provides a more informative view of the vehicle surroundings, particularly for parking assistance, by joining overlapping sections from multiple perspectives.
