White spot compensation

One of the inherent, general characteristics of CCDs is that white spots may appear in the image at slow shutter speeds or during shooting at high temperatures.

To moderate this phenomenon, this camera is provided with a white spot compensation func- tion.

How to use

White spot detection

Because the number of spots and their size differ with the temperature and shutter speed, etc., it is necessary to detect the positions of the white spots under the conditions of use before the white spot compensation is used.

1. Set the conditions for use (shutter speed, etc.).

2. Ensure that no light falls on the CCD by closing the lens iris, etc. (When a motorized lens is used, the iris will be closed automatically.)

3. Display the [KY-LINK] application software’s Process setting screen.

4. Set the Pixel comp. item to ON.

5. When the Pixel check button is clicked, detection of white spot positions starts. The detec- tion may take several minutes.

6. When the detection is completed, the [Process completed] message appears.

MEMO

•The camera’s white spot compensation function cannot compensate completely for all white spots. White spot detection and compensation by this camera can be performed under the following condi- tions. White spot compensation is not possible under other conditions. Even when these conditions are met, the properties of the white spots may prevent compensation.

Detection and compensation area:

Area of 1024 ⋅ 1024 pixels at the center of the screen.

No. of detections and compensations: Within a total of 15 spots.

•The [PIXEL CHECK FAILED] message may appear if light enters the CCD while white spot detection is being performed, or due to the conditions of the white spots. In this case, confirm that light is not falling on the CCD. If light is not falling on the CCD but the message nevertheless appears, increase the shutter speed one step and perform the detection again.

•During white spot detection, the image in the live window will become a still picture, but this is normal.

•When white spot compensation is carried out, the compensation of the pixel data is performed based on surrounding pixel data, which means that accurate data may not be obtained in case of an image with fine details.

•The result of the white spot detection is retained until the next white spot detection is performed.
