Description

[0001] The present invention relates to an intelligent camera system for a two-wheeled vehicle having a detachable high-resolution multi-channel camera module,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a video recording system for a vehicle, and more particularly, to a camera system capable of picking up and storing an external situation in a running or parked state.

Car camera systems are sometimes referred to as black boxes.

The black box collects and stores the flight record information of the aircraft, analyzes the flight record, analyzes the collected information in case of an aircraft accident, identifies the cause of the accident, improves the defect, and is used for safe flight. A vehicle black box has been proposed and used on the basis of an aircraft black box.

Unlike the airplane, the black box for the vehicle has been developed to pick up and store the operation status of the vehicle around the image.

The fact that the vehicle black box can record the image-driven operation situation has become possible because the development of peripheral technology such as camera and projection information processing device is performed.

Such a car camera system is installed inside a vehicle and stores driving images. When an accident occurs, the stored image is analyzed to identify the cause of accidents, the responsibility of the accident site, and the severity of the accident, and to provide proof of legal processing.

However, according to the conventional vehicle camera system, one channel, two channels, four channels, etc. have been proposed depending on the number of image cameras.

Each channel is provided to pick up an image of the front and rear sides depending on the installed direction. It is preferable that the channel is installed to acquire images in four directions, that is, four channels in order to minimize the blank space of the surveillance area around the vehicle.

However, when acquiring images from four channels, there are limitations in acquiring and storing VGA and HD-level shapes.

The reason for this is that the full-HD high-resolution image is twice as many as the HD-level image, and the data amount is doubled, resulting in data loss during data transmission, SD card) capacity problem occurs.

Of course, if the capacity of the storage device is increased, the problem of the capacity limit may be solved, but there is a problem that the data processing delay and the manufacturing cost increase due to the use of the large memory, which is difficult to adopt easily.

Nevertheless, the VGA-grade image is much inferior to the full-HD image and can not effectively cope with the image reading, so that a high-resolution image is required.

In order to solve the problem of the loss of the image data and the lack of capacity of the storage device, a 4-channel product combining a HD class 2 channel and a VGA class 2 channel has been introduced. In general, 2-channel products are mainly used.

There is a malfunction that prevents the black box from functioning properly due to frequent malfunction that the image is not stored properly.

In addition, according to the related art, since a plurality of deserializer modules are built-up in the form of an original board in a main body, there is a problem of an increase in manufacturing cost, and the number of channels, Channel type product. For example, when a user who uses a 1-channel black box product wants to increase the number of channels, there is a disadvantage that it can not be expanded originally. As a result, a multi-channel product having a desired number of channels is purchased again There is an evil that must be done.

This results in wasted resources and environmental pollution, and creates an adverse impact on consumers, which adds to the excessive economic burden.
