Pixel Defect Compensation - Black Point; Pixel Defect Compensation - White Point; Getting Of Reference Values; Factory Default Setting - Nikon D60 Repair Manual

(7) Pixel defect compensation - black point
When pixels of which the output level is under specified value with LV13 equiv., are detected, the
coordinates of the detected pixels are rewritten as pixel defect compensation data.
(8) Pixel defect compensation - white point
Shots are taken on the dark surface. In case the pixel output is found to be beyond the standard value, the
detected pixel coordinate is additionally written as the pixel defect compensation data.
(9) Getting of reference values
・Sensitivity reference value calculation
The reference body is faced to the color viewer of LV13 equiv. with the ND filter (-5 step) being put
between them. Then, store the G output average value of the center (425 pixels × 425 pixels) is stored in
the D60BSD.DAT file as the sensitivity reference value.
・Sensitivity ratio reference value calculation
The reference body is faced to the color viewer of LV9 equiv. (without filter) and to the color viewer of
LV13 equiv. with the ND filter (-3 step) being put between them. Then, the sensitivity ratio reference
value GR and GB is calculated, based on the G/R/B output average of the center (425 pixels × 425
pixels), and they are stored in the D60BSD.DAT file.
It is necessary to calculate the reference values of "Sensitivity" and "Sensitivity ratio" in order to prevent
the color temperature fluctuation caused by color viewer's changes over time from affecting the results of
the shooting image adjustment. By using the reference body, calculate the reference values once in about
every 3 months, when the fluorescent of the color viewer is replaced.
The reference value file D60BSD,DAT is created after getting the reference values.
(10) Factory default setting
By reset the settings of camera, factory default settings are restored.
Select the language and video mode to perform.
Because this setting of RP TOGO-PCB is blank, be sure to set the initial default setting when the TOGO-
PCB is replaced.
When this setting is used, the USB mode is set to "Mass Storage" mode.
(11) Confirming the Data
Storing and restoring each register is the function used when some trouble occurs and ask to send backup
data to Service Planning for analysis.
(12) Version no./ Serial no.
RISC firmware version and serial number are indicated. Serial number can be written.
※ Whenever the license sheet is replaced, be sure to input the serial number.
(13) TFT adjustment
Flickering, color and luminance of TFT are adjusted.
※ Whenever the TOGO-PCB and TFT monitor are replaced, be sure to perform "REWRITING THE TFT
FIXED VALUE.".
