1.4 Function Descriptions In this section, we will outline the MAVIS IM-30/IM-100 camera control functions. To ensure proper implementation, please carefully review the, limitation parameters and formula calculations, listed below. 1.4.1 AOI (Area of Interest) The AOI (Area of Interest) function allows users to select an area of interest, for the camera’s CMOS array to specifically read, display, and transmit. Figure 1-1: AOI (Area of Interest) The AOI function will also enhance camera

current settings is 5. Formula 1: Max. Frames/s = 1 / (((240 + 2) x 15.28us) + 15.28us) Max. Frames/s = 269.2 Formula 2: Max. Frames/s = 1 / (5 x 125us) Max. Frames/s = 1600 Formula 3: Max. Frames/s = 1 / (1000 us + 28us) Max. Frames/s = 972.76 By using the calculations above, the AOI for this particular scenario can be calculated at 269 frames per second. 1.4.2 Test Pattern The MAVIS IM-30/IM-100 series cameras offer an internal generated test pattern for testing came

1.4.3 Mirror Image The mirror image feature is only available in the MAVIS IM-100 camera. When you enable mirror image mode, the camera will reflect the image’s vertical axis, before data is transmitted out of the camera. In factory mode, the mirror image is disabled and the order of transmission for the pixels in each line is pixel 1, pixel 2, pixel 3, to 640. When mirror image mode is enabled, the order of transmission for each line is pixel 640, pixel 639, pixel 638, to pixel 1.

1.4.4 Gain and Brightness The Gain and Brightness adjustment functions are accomplished by manipulation of the sensor’s digital output signal. Please refer in Figure 1-4; when the gain is set to 0, the full 10bit output range of the camera’s CMOS sensor will mapped directly to the 8bit output range of the camera. In this situation, a gray value of 0 is output from the camera when the pixels in the sensor are exposed to no light and a gray value of 255 is output when the pixels a

It should be noted that this setting moves the response curve to the left; therefore increasing the 8bit value output from the camera for any given 10bit value from the sensor, and also increasing the apparent brightness of the image.

1.4.5 Lookup Table MAVIS IM-30/IM-100 cameras have a sensor that reads pixel value at a 10bit depth; however, the camera outputs pixel values at an 8bit depth. When set for 8bit output, the camera normally uses an internal process to convert the 10bit pixel values from the sensor to the 8bit values transmitted out of the camera. When making the 10 to 8bit conversion, the internal process takes the camera current gain and brightness settings into account. The MAVIS IM-30/IM-100 camera a

Figure 1-7 is for a lookup table where the values are arranged so that the camera output increases quickly as the sensor output moves from 0 through 511 and increases gradually as the sensor output moves from 512 through 1023. Figure 1-7: LUT with Values Mapped for Higher Camera Output at Low Sensor Readings Upload a Lookup Table The EZView utility offers an LUT enable and upload button that can be used to easily load a file containing a customized lookup table into the camera.

1.4.6 Shutter (Exposure) The camera exposure time is related with shutter speed or camera frame rate. MAVIS IM-30/IM-100 allowed to set shutter speed range from 20us to 81900us. While user set the exposure time (shutter speed) longer then frame acquisition speed then camera frame rate will be reduced. For example: if user set the frame rate in 30fps but set the shutter speed in 36000us. Maximum exposure time (Shutter speed) = 1s / frame rate 36000us = 1s / frame rate Camer

1.4.7 Input/Output Input Ports The MAVIS IM-30/IM-100 offers 2 input ports; designated as Input Port 0 and Input Port 1. Both ports are TTL level. The input ports are accessed via the 10-pin circular connectors on the back of the camera. Please refer Table 2-1 for input port pin assignments. For each port, an input voltage between 0.0 and 1.5VDC indicates a logical 0. An input voltage between 3.5 and 5.0 VDC indicates a logical 1. Typical current draw for the input port is 1mA. Fig

24mA. An output voltage between 4.2 and 5.0VDC indicates a logical 1. The minimum high level output voltage (i.e., 4.2VDC) will be present when the driver is sourcing the maximum allowed output current of 24mA. Figure 1-7 is an example of a typical circuit that you can use to monitor an output port with a LED or an Opto-coupler. Note that current in the circuit is limited by an external resistor. Figure 1-10: Typical Output Signal By default, Output Port 0 is assigned to transmit an int

1.4.8 External Trigger The external trigger (Ex-Trig) input signal can be used to control the start of exposure. A rising edge or a falling edge can also be used to trigger exposure start. The External Trigger Mode is also used to enable the Ex-Trig exposure start control; enabling users to select rising or falling edge triggering and to assign a physical input port to receive the Ex-Trig signal. The Ex-Trig signal can be periodic or non-periodic. When the camera is operating under c

Level Controlled Exposure Mode When level controlled mode is selected, the length of the exposure is determined by Ex-Trig signal alone. If the camera is set for rising edge triggering, exposure begins when the Ex-Trig signal rises and continues until Ex-Trig signal falls. If the camera is set for falling edge triggering, exposure begins when Ex-Trig signal falls and continues until Ex-Trig signal rises.

1.4.9 Strobe Control This feature allows a user to enable and parameterize up to four strobe light control output signals. The signals are designated as Strobe 0, Strobe 1, Strobe 2, and Strobe3. Each strobe signal can be set to on or off and active high or low by logical value, please refer to section 5, “Function Library”, for command definitions. The strobe delay is determined by a combination of two values. The first is the setting in the Delay Value and the range from 0 to 4095. Th

1.6 Integrate Enabled Signal Timing The time between the start of exposure and the rise of the Integrate Enabled (Int-En) signal will be less than 10 nanoseconds. The time between the end of exposure and the fall of Int-En signal will also be less than 10 nanoseconds. This is very good performance, and is due to the design of the camera output port circuitry. Figure 1-12: MAVIS IM-30/IM-100 Camera Timing Chart - 19 -
