WARNING
THE COMPONENTS IDENTIFIED BY THE MARK ON THE SCHEMATIC DIAGRAM AND IN THE PARTS LIST ARE CRITICAL FOR SAFETY.
PLEASE REPLACE ONLY BY THE COMPONENTS SPECIFIED ON THE SCHEMATIC
DIAGRAM AND IN THE PARTS LIST. IF YOU USE PARTS NOT SPECIFIED, IT MAY RESULT IN A FIRE AND AN
ELECTRICAL SHOCK.

SAFETY CHECK-OUT
After correcting the original problem, perform the following
safety check before return the product to the customer.
1. Check the area of your repair for unsoldered or poorly
soldered connections. Check the entire board surface
for solder splasher and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.
4. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer
and recommend their replacement.
5. Check the B + voltage to see it is at the values
specified.
6. Make leakage - current measurements to determine
that exposed parts are acceptably insulated from the
supply circuit before returning the product to the
customer.

If the camera is not used in any way for 30 seconds, this function turns features such as the LCD monitor off (sleep mode) to prevent battery depletion and the waste of power when the AC power adapter is connected. If the camera is then left unused for a further period, the Auto power save function turns the camera off. This period can be set to 2 or 5 minutes on this camera. z The Auto power off function does not operate in PC mode, during automatic playback,

As the brightness of the subject changes, a digital camera maintains the amount of light hitting the CCD at a constant level by adjusting the aperture and shutter speed. When the amount of light striking the CCD doubles, the EV increases by 1. Likewise, when the light is halved, the EV decreases by 1.

3-3-1. Technical Outline

Equipped with a 1/2.5-inch square-pixel interline CCD (with 4.1 effective megapixels) and a 3.4x optical zoom lens
featuring the new slimline sliding lens system.
Features a new image signal processing LSI chip, called the XCS2_IC (IC204, CSP_IC), built into the MAIN PWB ASSY.
This CPU incorporates the standard peripheral I/O functions as well as the peripheral functions required for still image processing into a single chip. Standard peripheral I/O consists of the interrupt controller, DMA controller, clock controller, SDRAM controller, block selection controller, serial I/O, multifunction timer, monitoring timer, programmable I/O ports, USB 2.0 (Full Speed), microprocessor ADC, microprocessor DAC, image processing circuit, JPEG compression/ expansion circuit, display control circuit, still image processing and card interface circuit.
In the white balance procedure, an algorithm has been installed that provides an estimation of the light source used for
shooting based on the brightness and light source color detected when the shot was taken, and a white balance (WB) compensation function based on that estimation. The new algorithm is designed to prevent “hunting” due to field-of-view slippage by providing more accurate brightness and color detection, and to allow the installation of a powerful algorithm for distinguishing between the light source and the original subject colors.
Flash brightness is adjusted using the CCD-TTL method in which the flash brightness is calculated from the CCD
feedback data generated by the pre-flash.

Explanation of the imaging circuit functions
Analog video signals output from the CCD (1/2.5-inch with 4.1 effective megapixels) undergo pseudo-color correction
processing, adaptive interpolation processing, amplification and signal mixing in the AFE_IC (IC151; CSP_IC). The converted digital signals are then sent to the single-chip image signal processing LSI chip, known as XCS2_IC (IC204,
CSP_IC). Input data from the CCD * The 10-bit digital image data (corresponding to 1H) sent from the imaging circuit (AFE BLOCK) is sent to XCS2_IC,
buffered in the chip’s IBFC and replaced by 16-bit (96 MHz) data. The replaced 16-bit (96 MHz) image data is then stored
in the XCS2_IC [SDRAM] via the XCS2_IC [I/O BUFFER]. The image data for each frame is temporarily stored in the
XCS2_IC [SDRAM]. * At the same time, the AE for [AUTO] is calculated using the 10-bit image data input to XCS2_IC and the data required for
AE, AWB and AF is sent to the XCS2_IC [SDRAM]. In the XCS2_IC [SDRAM], the data is sent serially to AFE_CS to
obtain the correct AE, AWB and AF. Recording onto an xD-Picture card
The image data stored in SDRAM is converted to 16-bit (96-MHz) data by [IBFC] in XCS2_IC one line at a time and then
sent to [YC PRO]. In [IBFC], the 32-bit Y and C signals are each converted to 8-bit Y, Y, Cb and Cr signals and sent to the
XCS2_IC [SDRAM]. The image data stored in the XCS2_IC [SDRAM] is compressed using [JPEG] in XCS2_IC and then
recorded sequentially onto the xD-Picture card via [MEDIA] in XCS2_IC. Playing back images from an xD-Picture card
The compressed image data from the xD-Picture card is sent to XCS2_IC and stored in the XCS2_IC [SDRAM] via
[MEDIA]. The compressed image data stored in the XCS2_IC [SDRAM] is expanded using [JPEG] and again stored in
the XCS2_IC [SDRAM]. The expanded image data is sent to [YC PRO] via [IBFC]. In [YC PRO], gain control and
aperture processing is applied for the brightness signals and color difference signals, after which the data is again stored
in the XCS2_IC [SDRAM]. The image data is then displayed via [ENCD] and [D/A]. In movie shooting mode
The 10-bit digital image data output from the imaging unit is converted to 8-bit Y and C signals by the XCS2_IC [YC PRO]
and sent to the XCS2_IC [SDRAM]. The image data is compressed using [JPEG] in XCS2_IC and again stored in the
XCS2_IC [SDRAM]. The compressed data is then recorded sequentially onto the xD-Picture card via [MEDIA] in
XCS2_IC. The imaging system adjustment data is stored in FLASH_ROM (IC202).
Explanation of the LCD controller functions
The R, G and B signals processed in the XCS2_IC image signal processor are output to the LCD panel via [LCD
CONST].

The LCD monitor (2.0-inch 1.54 megapixels) used in the camera uses a low-temperature polysilicon TFT color LCD
screen.

3-3-4. DCTS Board Block Functions

backlight), 5.2V (lens), XCS_3.3V (XCS2_IC), CAM3.3V (AFE), D3.3V (LCD and F_ROM) and AD_3.3V (AUDIO/VIDEO).
