PRODUCT DESCRIPTION
1.1 FEATURES ..........................................................................................1-1
PhotoPC700 is a compact and high performance digital camera equipped with total 1300K
pixels(available pixels 1200K) and built in Color LCD view monitor. Most of the parts are same as
those of PhotoPC600. Therefore, since this manual mentions only newly added parts and
functions and different points from PhotoPC600, refer to the Service Manual of PhotoPC600 for
other details.
High resolution color CCD applied
Optical size:1/2.7 inch color area
Total Pixels:1343(H) x972(V)
Available Pixels:1290(H) x 966(V), 24 bit output
Unlike PhotoPC and PhotoPC500, since JPEG compression is performed on the circuit,
processing time after shooting is quite shortened.
Back-up function by capacitor for Date and Time setting is added.
In the PhotoPC600, the date and time setting is cleared when the battery energy runs out without
connecting AC adapter, since the back-up battery is not built in. However, in the PhotoPC700, the
setting data can be maintained more than 30 minutes since the capacitor with large capacity is
built on the SY1 board.
High serial interface is built in.
Data transmission speed is maximum 230Kbps. (However, serial communication speed at PC
side requires more than 19200bps)
White Balance:Auto white balance +Fixed white balance
Exposure Control:Program auto exposure + Manual adjustment
4MB Flash Memory Standard is built.(Compact flash memory cards are available)
Picture Size:1280 x 960, 640 x 480, 1280 x 480(Panorama)
Viewfinder:Optical real image view finder
Shooting Mode:Digital two-times zoom, Panorama, Continuous shooting, Black and
White.
Direct print function:Direct printing is available just by connecting the camera and
printer(EPSON Stylus Photo, EPSON Stylus Photo700,
ESPSON Stylus Photo EX, EPSON Stylus Color 800, EPSON Stylus
Color600) and downloading exclusive utility to the camera without
using PC.
The number represented by an asterisk varies, depending on the country.

CAUTION
When shooting the poor contrast or dark subject, there are some cases
that auto focus does not work well. Especially, the auto focus can not
operate normally for the subject that requires flash light. In this case,
focus the subject 1.5m forcibly and shoot it.

Manual exposure adjustment is available(±2)
Viewfinder:Optical real image view finder (View range80%)
Flash Range:0.2m - 2.4m
CAUTION
Shooting within 0.2m at macro mode with flash light will be overexposure. Therefore, take enough light from outside when shooting.

Available number above is measured by EPSON.co., and the number
varies more or less depending on the subject.
If extension function such as direct printing is downloaded to the

When the available number becomes 0, stand-by light(red) turns on
and becomes impossible to shoot. Although this is not malfunction,
some users misunderstand this phenomenon as malfunction.

the table above is just average number, therefore, actual number
does not reach to that average number in some cases, depending on
the result of JPEG compression.
