5-2 CCD Section (1) - CCD Image Adjustment - (DC20 E only)
This camcorder is provided with a primary-color-filter CCD having 2,000,000 pixels. Since the number of CCD pixels is in-
creased, two signal processing circuits are provided for the left-side and right-side imaging areas. For eliminating a level difference
between signals on these two signal processing circuits, it is required to perform initial adjustment using a dedicated tool. The
characteristics of the CCD (sensitivity, void/stuck pixels) largely depend on its temperature, and there are subtle differences in the
CCD characteristics due to variations in production. Therefore, carry out CCD image adjustment twice in total, i.e., at low tempera-
ture (immediately after power-on) and at high temperature (in a lapse of certain time after power-on).
Note)
For CCD image adjustment of this camcorder, it is required to modify the CCD image adjusting tool DY9-1391-000 using the CCD
image adjusting tool modification kit DY9-1404-000.
