5-6-7 CCD Pixel Missing Compensation
Note)
(1) If more than the above number are detected in adjustment, the result of adjustment is indicated as NG and the correction is not
performed. Further, if three consecutive missing pixels in a row are detected, the correction is not performed either.
(2) The number of white dot increases with the temperature of the CCD, causing a change in detectable level. If the adjustment is
performed after a lapse of time longer than the specified period of power-on, the temperature of the CCD becomes higher than a
preset temperature level to result in an increase in the number of white dots detected. In this situation, CCD Pixel Missing
Compensation cannot be made properly.
(3) In addition to the CCD Pixel Missing Compensation function mentioned above, this product is provided with a function for
automatically correcting pixel missing points each time power is turned on and a function for automatically correcting pixel missing
points at the time of shooting at a dark object (interlinked with AGC level adjustment).

Preparation)
(1) Carry out compensation for CCD pixel missing in the product state.
(2) Adjustment condition
Shooting mode : Program AE
AF : OFF (Focus short range)
ZOOM : Telephoto-end
Demo mode : OFF
Image stabilizer : OFF
Procedure)
(1) According to the table shown below, carry out CCD Pixel Missing Compensation. (Perform this step about 20 to 60 minutes after
power-on. For the DC20 E, be sure to conduct the CCD Pixel Missing Compensation after CCD image adjustment has been made.)
(2) If the result of adjustment is NG (status 09), refer to the error code table shown below.
Furthermore, by observing an actual image, check for stuck/void pixels. Then, judge whether the result of adjustment is OK or NG.
(In the case of NG, replace the CCD PCB with a new one.)
