1 About the Cheetah Camera
1.1 General
The Cheetah Python series of cameras provide an imaging platform with the latest digital
technology and industrial grade components. They use CMOS imaging sensors and offer a
broad range of resolutions and frame rates. Cheetah cameras are available in both
monochrome and color.
The cameras in this manual are compatible with the USB3 output interface. A GeniCam™
compliant programming graphical user interface ships with the camera. The following
table describes the C5180, C4181, and C4180 model cameras covered in this manual.

Cheetah CMOS cameras are advanced, high-resolution, progressive scan cameras. They
are fully programmable and field upgradeable. Programmable functions include exposure
control, frame rate control, area of interest, subsampling, pixel averaging, gain, offset,
triggering options, strobes, output control, defective pixel correction, and user-
programmable look-up tables (LUT). The cameras use ON Semiconductor area scan
Python CMOS image sensors and feature a built-in processing engine, low noise
characteristics, and optimized thermal distribution.
The Cheetah C5180, C4181, and C4180 model cameras use global shutter operation for
superior motion capture and exceptionally high frame rates for use in high throughput
applications. The cameras can control exposure time using internal controls or an external
pulse width. They support exposure times up to 1 second with 1µs increments. The
cameras also support analog gains up to 10 dB (3.17x).

Built-in gamma correction and user-defined look-up table (LUT) capabilities optimize the
camera’s dynamic range features. Defective pixel correction (DPC) and hot pixel
correction (HPC) correct for pixels that are over-responding or under-responding. Auto
White Balance (AWB) is available in color cameras to correct for color temperature. The
cameras have a USB3 compatible interface that includes 8- and 10-bit data transmission,
as well as camera control functionality in one cable. There is also support of active or
passive Canon EOS lenses.
The camera’s ruggedized design and flexibility enable its use in a wide and diverse range
of applications including machine vision, metrology high-definition imaging and
surveillance, medical and scientific imaging, intelligent transportation systems, aerial
imaging, character recognition, document processing and many more.
