1. Measurement of sharpness When multiple cameras are used for testing, the same lens should be used (it is recommended to use fixed focus and two variable lenses). The center circle of the test card appears on the right and left sides of the monitor screen. Clear and accurate. Count a total of 10 vertical lines and 10 horizontal lines for the given tick marks. Represents vertical resolution and horizontal resolution, respectively, and the corresponding set has given the number of lines. For example, the vertical 350 line level 800 line, at this time it is best to use a black and white monitor. The test can focus on distant objects or focus on the edge. It is best to use both, and you can see the differences in this camera (for far and near convergence).
2. Illumination The camera is placed in a dark room. Before and after the dark room, there is an active 220V self-firing lamp. Here, a voltage regulator is set to adjust the darkness of the dark room lamp with the voltage regulator to adjust the voltage. The voltage can be adjusted from 0V to 250V. Indoor lighting can also be adjusted from the darkest to the brightest. Record the next lowest illuminance when the camera's aperture is at its maximum during the test (dimming the active light regulator to a darker one). Record the next minimum illuminance value to the minimum, and adjust the pressure on the front and back lamps respectively.
3, ball-shaped distortion to see the ball-shaped distortion to test card placed in front of the camera so that the entire sphere appears on the screen to see whether the round spherical oval, the camera forward, see the center of the circle with or without amplification, and then test the distance, corner , whether the box has arc distortion.
4, color reproduction test test This parameter should be selected color monitor. First observe the characters and costumes from a distance to see whether there is color distortion or not. Compare the objects with vivid colors. Look at the sensitivity of the camera. Take the color picture book in front of the camera. Look at the picture clearly, too light or too thick, and respond to the motion again. The color objects are photographed for color smearing, lag, blur, etc. The test conditions such that the maximum illuminance of the camera should be measured under 50+10V illuminance at 50V, that is, plus ten volts per camera minimum illuminance, and the aperture should maintain the closest state.
5, backlight compensation test This parameter has two methods: one is in the dark room, the front of the camera to adjust the pressure to open the light, to the brightest, and then place a picture or text under the lamp, the camera welcome camera To see if the image and text can be seen, the picture is not dazzling, and adjust the AL, AX pullout switch to see if there is a change, which effect is best. The other is to take the camera out of the window when the sun is shining. At this time, you can see if the image and text are clear.
6, the lowest power consumption voltage, use a multimeter to measure the current, use a small voltage regulator to adjust the voltage.
