Selects the type of test pattern that is generated by the camera as image source. The test patterns are sensor specific and may vary depending on the model.
|
If your camera has color gains > 1, some images might appear colored instead of gray. To see the true test image, you should display the RAW image data instead of a debayered RGB image representation. |

Values description
•Off: No test pattern is generated. The image acquired by the sensor is displayed.
•Black: The sensor generates a test image with the darkest possible image.
•ChessPattern: The sensor generates a test image with a chess pattern.
•ColorBar: The sensor generates a test image which is filled with stripes of color including white, black, red, green, blue, cyan, magenta and yellow.
•FPGABlack: The FPGA generates a black test image.
•FPGAChessboard: The FPGA generates a test image with alternating pixels from zero intensity and maximum intensity.
•FPGAColorStripe: The FPGA generates a color stripe test image.
•FPGAFramecount: The FPGA generates a homogeneous test image that starts with zero intensity and gets brighter with each frame. When maximum intensity is reached the sequence starts again.
•FPGAGrayscale: The FPGA generates a test image with a horizontal gradient. The gradient starts at zero intensity on the left side and reaches the maximum intensity on the right side.
•FPGAVerticalGrayscale: The FPGA generates a test image with a vertical gradient. The gradient starts at zero intensity at the top of the image and reaches the maximum intensity at the bottom of the image.
•FPGAWhite: The FPGA generates a white test image.
•GreyDiagonalRamp: The sensor generates a test image with a diagonal gradient. The gradient starts at zero intensity and reaches the maximum intensity in a diagonal direction.
•GreyDiagonalRampMoving: The sensor generates a test image with a moving diagonal gradient. The gradient starts at zero intensity and reaches the maximum intensity in a diagonal direction. The ramp moves across the image.
•GreyHorizontalRamp: The sensor generates a test image with a horizontal gradient. The gradient starts at zero intensity and reaches the maximum intensity in a horizontal direction.
•GreyVerticalRamp: The sensor generates a test image with a vertical gradient. The gradient starts at zero intensity and reaches the maximum intensity in a vertical direction.
•GreyWedgeMovingSensor: The sensor generates a test image with moving grey wedges.
•GreyWedgeSensor: The sensor generates a test image with grey wedges.
•RampingPattern: The sensor generates a test image with a moving ramping pattern.
•SequencePattern1: The sensor generates a test image with defined sequential pixel values.
•SequencePattern2: The sensor generates a test image with defined sequential pixel values.
•White: The sensor generates a test image with the brightest possible image.
