Description

Technical Field

[0001] This application relates to the field of display control technology, specifically to a panoramic camera module and a panoramic camera device. Background Technology

[0002] Panoramic technology is a technique that uses multiple cameras to capture images of the surrounding environment and then stitches them together to obtain a 360-degree panoramic view. Originally used in security monitoring, this technology has recently been introduced into automotive electronics to improve drivers' 360-degree field of vision and enhance driving safety.

[0003] A typical automotive panoramic camera system consists of 4-6 monocular cameras, mounted at the front, rear, left, and right of the vehicle. Each camera captures a local field of view, and then an image stitching algorithm seamlessly combines the images from multiple perspectives into a single panoramic image. This panoramic image provides the driver with a 360-degree unobstructed view, eliminating blind spots from traditional rearview mirrors and the vehicle itself, effectively improving driving safety.

[0032] To make the objectives, technical solutions, and advantages of this utility model application clearer, the technical solutions in the embodiments of this utility model application will be clearly and completely described below in conjunction with the embodiments of this utility model application. Obviously, the described embodiments are only a part of the embodiments of this utility model application, not all of them. Based on the embodiments of this utility model application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] In this field, the most common display mode switching is full-screen switching. If the entire screen is in the first display mode (non-peeping mode) or the second display mode (peeping mode), it is difficult to achieve a situation where some areas of the display panel are in the first display mode and some areas are in the second display mode.

[0034] Currently, cameras in the automotive industry are primarily used for monitoring. They acquire image information internally, then feed this information back to a serializer for processing. The serializer then relays the image information to the motherboard, which in turn controls external devices to output corresponding image data. However, the reliance on imported chips significantly increases production costs. Reducing costs typically involves altering the hardware architecture or lowering response speed, which in turn introduces performance instability. This makes designing a new automotive panoramic camera structure a pressing issue.

[0035] To address the aforementioned issues, this application proposes a panoramic camera module. It utilizes a self-developed chip to provide a serial module and an image sensor module. Power is supplied to the power control module and serializer via an external coaxial connector and external power supply, enabling the power control module to generate various power signals to provide multiple power sources for the serial and image sensor modules. Simultaneously, the serial module establishes a communication connection with both the power control and image sensor modules. Upon successful communication, the serial module receives image information acquired by the image sensor modules and feeds this information back to an external motherboard. The motherboard then controls corresponding external devices to process the image information. By utilizing multiple image sensor modules, panoramic image acquisition is achieved, realizing the monitoring function of a panoramic surveillance camera. This achieves panoramic monitoring while reducing production costs.
