USB影像模組、USB攝像模組:USB2.0相機模組、USB3.0攝像頭模組

USB 影像模組是一種透過 CMOS 影像模組板給 PC 或 嵌入式系統 (如ARM,樹莓派,Odriod和類似的電腦模組)。USB 影像模組可以支援大多數的平行介面的攝像頭模組和 MIPI 影像模組,包括全域及滾動式快門(Global Shutter and Rolling Shutter)。USB 相機模組是以 USB 接口來做連結,非常的方便自訂和使用。更重要的是 USB 影像裝置不需要任何的驅動程式。

攝像頭種類

UVC(USB影像系統)和攝像頭模組

UVC 是 USB 裝置之一。UVC的驅動程式已預裝到作業系統,不需要而外裝置。電腦和手機可以透過USB接口連接,方便使用。不管是Windows,Linux,Android,IOS 都有所支援。

USB 影像模組區分成攝像頭模組,和影像頭機組。透過USB與主機系統做連結。將相機鏡頭與圖像感應器結合成相機單元。圖像感應器主要是區辨圖片的視角,畫質,折射等,整體結構做計算給予最好的圖片架構。影像頭機組主要管理圖像處理應用,過濾出適合的波長,DSP 的操控,感應的資訊處理等的操作。IADIY UVC相機板是使用崁入式MIPI的相機模組做自製的相機。相機模組包括了許多功能。比如:廣角攝像(WDR),低光攝影,和不同角度的影像都可以透過IADIY自製屬於自己的相機。

Global Shutter Camera Module: Unlocking Dynamic Imaging with Global Shutter

An electronic shutter electronically turns the image sensor on and off to control exposure. The sensor starts detecting light when activated and stops detecting light when deactivated.

Rolling Shutter vs Global Shutter Camera Module

Rolling shutter cameras capture the scene line by line, from top to bottom, causing a time difference between top and bottom parts. Motion or camera movement results in the distortion known as the rolling shutter effect.

On the other hand, global shutter camera is designated to capture an image by simultaneously exposing all the pixels in its image sensor to light for a brief period of time. Unlike a rolling shutter camera, which scans the image sensor row by row, a global shutter camera captures the entire image instantaneously.

Rolling Shutter Distortion

Rolling shutter distortion effect

Rolling shutter distortion is an effect that can occur while using rolling shutter camera to capture fast-moving subjects. It is caused by the delay between the beginning and the end of the sensor readout, this can result in vertical or horizontal lines appearing bent or slanted, giving the image a distorted appearance.

Visual anomalies

Since the rolling shutter captures different parts of the image at slightly different times, it can create motion blurriness. When there is an object moving at a very high-speed, it may appear distorted or elongated due to the time difference in capturing different parts of the target. This can be particularly noticeable in situations such as sports photography or capturing moving vehicles.

A faster shutter speed can help to the amount of time that the sensor is exposed to light. This means that there is less time for the subject to move while the sensor is being read, which can help to reduce motion artifacts. However… even with a fast shutter speed, rolling shutter distortion can still occur if the subject is moving at a very high speed. In these cases, the only solution is to use a global shutter equipped camera. For catching high speed or motion image, we recommend to try our global shutter camera module to see the advantages.
