1-2.Explanation of Terms
Adobe RGB (1998)A color space introduced as the working color space for Adobe Photoshop 5.0.
AdobeRGB encompasses almost all the colors reproduced by CMYK printers and is
intended primarily for printing applications. It was introduced as “SMPTE-240E” in the
RGB settings in Adobe Photoshop 5.0 and as “Adobe RGB (1998)” in the profile settings
from version 6.0 onwards.
CCD-RAWThis is the image data prior to signal processing (the reconstruction of the data read in
from the CCD as an image). Because the signal processing is performed on the computer, high levels of control are possible.
• To reconstruct images, FinePixViewer (on the enclosed CD-ROM) or the Hyper Utility
(optional) must be installed on your computer.
Color spaceRefers to the range of colors, expressed as two-dimensional or three-dimensional
numerical values, that can be reproduced by devices such as cameras, monitors and
printers. The sRGB and AdobeRGB color spaces are each shown as an xy color chart (a
coordinate color space in which colors are represented in two dimensions with no
brightness value). The range of colors that can be expressed by a particular color space
is indicated by a triangle imposed on the xy color chart. Colors become brighter as they
approach the outer edge of the xy color chart. This color representation method is
capable of showing all the actual colors.
Color TemperatureLow-temperature light sources, such as a candle flame, are strongly red, while high-
temperature light sources, such as a gas burner flame, are strongly blue. The color of
the light for these temperatures is expressed as a color temperature (K = Kelvin). The
light of the sun at midday in a completely clear sky is taken to be 5500K.
EV:A number that denotes Exposure Value. The EV is determined by the brightness of the
subject and sensitivity (speed) of the film or CCD. The number is larger for bright
subjects and smaller for dark subjects. 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.
JPEG:Joint Photographic Experts Group
A file format used for compressing and saving color images. The higher the compression
rate, the greater the loss of quality in the decompressed (restored) image.
White Balance:Whatever the kind of the light, the human eye adapts to it so that a white object still
looks white. On the other hand, devices such as digital cameras see a white subject as
white by first adjusting the color balance to suit the color of the ambient light around the
subject. This adjustment is called matching the white balance.
Exif Print:Exif Print Format is a newly revised digital camera file format that contains a variety of
shooting information for optimal printing.

3-3.Description of the Main Block Functions
3-3-1.Overview of the new technology
A number of technological innovations have been used on this model. These innovations are described below.
(1) Large-format (15.5 x 23.0 mm) “Super CCD Honeycom SRII” featuring a new structural design
• Ultra-high image quality with a maximum recorded image size of 4256 x 2848 pixels (12.1 megapixels) provided by the
“Honeycom Signal Processing System” and a resolution of 12.34 effective megapixels (high-sensitivity S pixels: 6.17
million; R pixels designed to increase dynamic range: 6.17 million).
• The “Super CCD Honeycom SRII” is a newly designed CCD that increases the dynamic range to roughly 4 times that of
the previous FinePix S2Pro and provides rich and detailed tonal gradations. It provides superb image quality featuring
high sensitivity, a broad dynamic range and a high S-N ratio.
• According to their needs, users can select either “D-Range: Wide” to take full advantage of the extensive dynamic range
or “D-Range: Standard”, which uses only the S-pixel signals to form the image and is ideal for continuous or high-speed
shooting.
• When “D-Range: Wide” is selected, the photographer can then choose “AUTO” mode, in which the camera automatically
sets the optimum dynamic range for the scene being shot, or set the dynamic range to “WIDE 1” or “WIDE 2” when the
shot is taken to achieve a particular effect.
• Sensitivity settings equivalent to ISO 100-1600 are available, allowing shots to be taken in wide variety of situations both
in the studio and outdoors.
(2) IEEE1394 and USB 2.0 interfaces allow high-speed transfer of image data to a PC. Also provided is a photography
function that transfers photographed images directly from the camera to a PC via the IEEE1394 interface. (Requires the
optional Hyper Utility HS-V2 version 3.0 software.)
23
3. Schematics
(3) In addition to sRGB, support is provided for the Adobe RGB (1998) color space, which is used as the standard color space
in the graphic design and printing fields.
• The inclusion of an additional partner chip with the UCS2 for image processing yields improved color space reproduction
and lower levels of noise.
(4) Image visibility is also improved through the use of a 2.0-inch low-temperature polysilicon TFT color LCD monitor featuring
a resolution of 235,000 pixels and 100% coverage.
(5) The use of a dedicated microchip for powering up means that media information is recorded even while the camera is
turned off, reducing the time between the camera being turned on being ready to shoot.
(6) The previous FinePix S2Pro needed 2 power supplies (2 CR123 button cells and 4 AA batteries), but the reduced power
consumption levels on the FinePix S3Pro allow it to run on a single power supply (4 AA batteries).
(7) Modifications to the base body allow improved viewfinder magnification, the adoption of D-TTL flash exposure control and
an X-sync speed of 1/180.
(8) A Firmware Update function has been included to allow for future functionality upgrades and support for special models.

3-3-2.Block function descriptions
(1) Imaging circuit (CCD BLOCK) (CAM BLOCK)
The analog video signals output from the new APS-size CCD Honeycom SRII (high-sensitivity S pixels: 6.17 million; R
pixels designed to increase dynamic range: 6.17 million) are processed using false-color correction (CDS), optimized
spacing (CDS), amplification (AGC) and signal mixing (CDS) in a single CSPIC chip (IC906; abbreviated as ACS), before
being converted (A-D) to 12-bit digital signals. The CSP-IC also incorporates the “TG/SSG” function, previously provided
as a separate IC, onto one chip. The converted digital signals are then sent to the signal processing IC (abbreviated as
UCS2; IC104; CSP).
(2) Image processor (PROCESS BLOCK) (Input data from the CCD)
The 12-bit digital image data (the section corresponding to 1H) generated by the imaging unit (CCD-CAM BLOCK) is sent
to the signal processing IC (abbreviated as UCS2; IC104), where buffer processing is performed in the IC’s internal buffer
to convert the signals to 32-bit (16-bit x 2) data (CCD-RAW data). The converted 32-bit data (CCD-RAW data) is stored in
the 16MB SDRAM (IC101 IC102 IC103 and IC106) via the I/O bus for the image signal processing IC. The image data for
each frame (4256 pixels x 2848 lines) is temporarily stored in SDRAM. Also, the 32-bit image data input to the signal
processing IC (abbreviated as UCS2; IC104) is used for additions performed by the AUTO computing unit and then sent
to the CAM BLOCK ACS (IC906) so that the optimal AE, AWB and AF values are obtained. (Recording onto the xD
Pictuer Card/Microdrive) The image data stored in the SDRAM (IC101 IC102 IC103 and IC106) is sent one line at a time
to the signal processor IC (IC104; UCS2; CSP) via the I/O bus in the signal processor IC. In the signal processor, the
data is unpacked and the following processes are called: 16 bit -> 10 bit conversion; preprocessing such as digital
clamping, gamma correction, and 10-bit -> 8-bit conversion for the R, G and B channels; YC processing to convert the 8bit RGB signals to Y:Cb:Cr=4:2:2, after which the Y, Cr and Cb 8-bit image data is returned to the internal buffer. In the
internal buffer, the 8-bit Y, Cr and Cb signals are sorted into a data format that facilitates DCT compression before being
recorded onto an xD Pictuer Card or Microdrive via the JPEG calculation unit and media controller. (Image playback from
the xD Pictuer Card or Microdrive) The compressed image data on the xD Pictuer Card is sent to the signal processing IC
(abbreviated as UCS2; IC104) as 8-bit image data and then sent to SDRAM (IC101 IC102 IC103 and IC106) via the
media control unit, the DMA unit and the internal buffer control unit. The image data temporarily stored in SDRAM (IC101
IC102 IC103 and IC106) is then returned to the signal processor IC (abbreviated as UCS2; IC104) and sent to the signal
processor unit via the media controller and JPEG calculation unit. The signal processor unit performs postprocessing in
which the 8-bit Y:Cr:Cb image signals are converted to 8-bit R, G and B signals. At the same time, the character display
signals are superimposed and sent to the LCD BLOCK. The imaging system adjustment data is stored in F_ROM
(IC314). The 8-bit brightness and color-difference signals processed by the signal processing IC (UCS2; IC104) are D-A
converted in the image signal processing IC encoder unit and the display character signals are superimposed, producing
analog RGB signals. Video (a composite video signal) is also included at the same time in the B component of the RGB
signal output. When the VIDEO terminal is inserted into the camera, a composite video signal is automatically output by
the detector.
(3) LCD Controller (LCD BLOCK)
The RGB analog signals output from the image signal processing IC encoder block are sent to the LCD controller IC
(IC500), where they are converted to digital RGB signals. The LCD controller IC also controls the LCD panel gradations
at the same time.
