2Introduction

The See3CAM_CU51 is a 5.0 Mega pixel, monochrome, UVC Compliant, USB3.0

SuperSpeed camera from e-con Systems, a leading embedded Product Design Services

Company which specializes in the advanced camera solutions. The See3CAM_CU51 is the

latest member of the See3CAM family of USB3.0 SuperSpeed camera products launched by

e-con.

The See3CAM_CU51 is a 5.0 MP monochrome camera with the S-mount (also

known as M12 board lens) lens holder. The S-mount is one of the most commonly used small

form-factor lens mounts for board cameras. The See3CAM_CU51 is based on the 1/2.5”

MT9P031, monochrome CMOS image sensor from Aptina.

This See3CAM_CU51 is a UVC-compliant USB3.0 SuperSpeed Camera that is also

backward compatible with USB2.0 host ports and does not require any special camera drivers

to be installed in the host PC. The See3CAM_CU51 is also backward compatible with the

USB2.0 High Speed interface, albeit at lower frame rates.

The CMOS sensor is operated in 12bits per pixel mode and the application will

receive the 12bits of greyscale information for every pixel. The application developer gets the

very high resolution 12bpp data for every pixel for performing accurate image processing

functions.

The See3CAM_CU51 is UVC-compliant camera and it does not require any

additional drivers to be installed on the PC. The native UVC drivers of Windows and Linux

Operating Systems shall be compatible with this camera. e-con also provides the sample

application (Qtcam) that demonstrates some of the features of this camera. However, this

camera can be utilized by any webcam supporting application like Skype etc.

3Scope

e-con provides a sample V4L2 application, called Qtcam, along with the

See3CAM_CU51 camera. Qtcam is a V4L2 video viewer and capture software for the linux

UVC driver, but customized to demonstrate some of the features of See3CAM_CU51.

This document describes about the usage of the Qtcam application on Ubuntu

[>=12.04 (LTS)] 32- and 64-bit Linux operating systems. This document also describes about

the special features of Qtcam camera application when it is used with See3CAM_CU51.
