  • Page 33: Internal Exposure Control - Electronic Shutter

    CHEETAH Hardware User’s Manual 2.1 EXPOSURE CONTROL 2.1.1 Internal Exposure Control - Electronic Shutter In global shutter, all pixels in the array are reset at the same time, allowed to collect signal during the exposure time and then the image is transferred to a non- photosensitive region within each pixel.

  • Page 34: Frame Time Control

    CHEETAH Hardware User’s Manual 2.2 FRAME TIME CONTROL 2.2.1 Internal Line and Frame Time Control The camera speed (frame rate) depends on the CMOS “read-out” time – the time necessary to read all the pixels out of the CMOS imager. The frame rate can be calculated using the following Formula 1.1:...

  • Page 35: Camera Output Control

    These camera settings combined with the output bit-depth (8 or 10-bit) to control the total the interface bandwidth. The output interface clock speed for the Cheetah Camera is 85-MHz (Camera Link Spec is 85 MHz maximum) It is important to match the camera’s output to the frame grabber.

  • Page 36: Area Of Interest

    For some applications the user may not need the entire image, but only a portion of it. To accommodate this requirement, CHEETAH provides one Region of Interest (ROI) also known as Area of Interest (AOI). The camera offers a pre-programmed quad full HD (QFD) AOI (3840 x 2160 resolution) to simplify camera setup for QFHD applications.

  • Page 37: Factors Impacting Frame Rate

    / averaging modes will have the effect of increasing the camera frame rate. The maximum horizontal window size (H) and the vertical window size (V) are determined by image full resolution (For example, C5180: 5180 x 5180 or C4181: 4096 x 4096).

  • Page 38: Table 18: C5180 Aoi Frame Rate For Various Aois

    The camera will calculate and display the actual frame rate at any horizontal and vertical window selection. Examples of C5180 Frame Rate performance at full resolution and within selected AOIs are described in Table 18.

  • Page 40: Sub-Sampling Decimation

    If an area of interest (AOI) is selected, then the field of view of the AOI is maintained. The C5180, C4181, C4180 and C2880 employ a ‘keep one pixel’, ‘skip one pixel’ sequence. When enabled in both x and y, every other pixel within a line is retained and every other line within the image is retained.

  • Page 41: Camera Triggering

    CHEETAH Hardware User’s Manual 2.5 CAMERA TRIGGERING 2.5.1 Triggering Inputs In the normal mode of operation, the camera is free running. Using the trigger mode allows the camera to be synchronized to an external timing pulse. . There are four input modes available for external triggering – computer (CC), internal (pulse generator), external and software.

  • Page 42: Triggering Modes

    CHEETAH Hardware User’s Manual “Pulse Width” – the trigger pulse width (duration) determines the exposure subject to limitations. “Internal” – the camera internal exposure register determines the exposure. CAUTION NOTE 1. The de-bounce interval MUST be smaller than the trigger pulse duration. Adjust the interval accordingly.

  • Page 43: Strobes

    CHEETAH Hardware User’s Manual Figure 17: Trigger Mode (Pulse Width Exposure Control) CAUTION: When using the internal exposure timer, if the next trigger is received prior to the completion of the previous exposure time, the trigger will be ignored. 2.6 STROBES The camera can provide up to two strobe pulses for synchronization with an external light source, additional cameras or other peripheral devices.

  • Page 44: Digital Gain

    CHEETAH Hardware User’s Manual 2.7.2 Digital Gain Digital gain can be varied from 1x (0dB) to 15.9 (24 dB) with a precision of 0.001x. 2.7.3 Digital Offset Digital offset is a digital count added or subtracted from each pixel. The range is +/- 512 counts.

  • Page 49: White Balance And Color Conversion

    The color representation in the image depends on the color temperature of the light source and CHEETAH has a built-in algorithm to compensate for this effect. When white balance correction is enabled, the camera collects the luminance data for each of the primary colors R, G and B, analyzes it, and adjusts the color setting in order to preserve the original colors and make white objects appear white.

Imperx, Inc. Rev. 1.6 6421 Congress Ave.

  • Page 81: Overview

    The CamConfig utility provides an intelligent, automated method of ‘discovering’ and ‘searching’ all available UART components in your PC and allowing the user to select the one that is connected to CHEETAH camera. CHEETAH Cam Configurator is expecting the serial interface DLL clserXXX.dll file to be located in C:\\Windows\System32.

  • Page 91: Figure 43: Aoi Functions

    CHEETAH Hardware User’s Manual Pixel Clock Rate – The Pixel Clock Rate determines the Line Readout Rate. Decreasing the Pixel Clock Rate will increase the time to readout a line. Zero-ROT - Unchecking Zero-ROT control increases the line readout time by one micro-second. As a general rule, the user should always enable Zero-ROT (checked) unless prompted by the camera to uncheck it.

    Checking the ‘in Y’ box discards every other line within the frame. Averaging: The Cheetah offers a four-into-one (4:1) averaging function for monochrome cameras only. Checking ‘in X’ averages two adjacent pixels within a line to produce a single pixel result.
