Why Does 4K30 Often Use MJPEG in USB Camera Modules?

The short answer is bandwidth A 4K frame contains more than eight million pixels. Sending thirty of those frames every second without compression creates a very large data stream. USB camera modules therefore often use MJPEG because JPEG compression reduces the amount of data that must travel across ...

What Is YUY2 Output in a Camera Module?

YUY2 is an uncompressed YUV video format YUY2 is a common way to transport video where luminance (Y) information is stored for each pixel and chroma information is shared between neighboring pixels using 4:2:2 sampling. In practical camera-module work, the important point is that YUY2 is not heavily ...

OEM 720p USB Camera Module: Define the Lens, Cable, and Housing Before Production

A lower-resolution camera can reduce the amount of image data a device must handle, but it does not remove the need for a controlled product definition. An OEM version can still change after the first sample through a different lens, cable length, connector, housing, or acquisition framework. If ...

Using a 1080p USB Camera Module as an OEM Configuration Baseline

Many OEM camera projects do not fail because the standard sample lacks image quality. They become difficult when several “small” changes - a different lens, longer cable, new connector, revised housing, or alternative software mode - are made after the sample has been approved. Each change may be ...

Why Lens Distortion and Vignetting Must Be Defined Before Camera Module Customization

A custom camera module sample may look acceptable on one monitor and still fail as a production specification. Terms such as ‘wide-angle,’ ‘low distortion’ and ‘no dark corners’ do not define how the image will be measured, which sensor area will be used or how much unit-to-unit variation is ...
