Information

Digital ESP (Electro-Selective Pattern) Light Metering

This determines the exposure by splitting the image into 49 areas and metering and

calculating the light levels in each area.

DPOF (Digital Print Order Format)

This is for saving desired print settings on digital cameras. By entering which images to print

and the number of copies of each, the user can easily have the desired images printed by a

printer or print lab that supports the DPOF format.

Eclipsing (Vignetting)

This refers to when an object obscures part of the field of view so that the whole subject is not

photographed. Vignetting also refers to when the image seen through the viewfinder does not

exactly match the image shot through the objective lens, so the photographed image includes

objects not seen through the viewfinder. In addition, vignetting can occur when an incorrect

lens hood is used, causing shadowing to appear in the corners of the image.

EV (Exposure Value)

A system for measuring exposure. EV0 is when the aperture is at F1 and the shutter speed is

1 second. The EV then increases by 1 each time the aperture increases by one F stop or the

shutter speed increases by one increment. EV can also be used to indicate brightness and

ISO settings.

Exposure

The amount of light used to capture an image. The exposure is determined by the length of

time the shutter is open (shutter speed) and the amount of light that passes through the lens

(aperture).

Image pickup device

This converts light passing through the lens into electrical signals. On this camera, light is

picked up and converted into RGB signals to build a single image.

ISO

International abbreviation for International Organization for Standardization. The sensitivity

setting used in digital cameras is based on the same ISO standard used for film sensitivity.

The sensitivity is denoted as shown in “ISO 100”. Higher ISO values indicate greater

sensitivity to light, so images can be exposed even in low-light conditions.

JPEG (Joint Photographic Experts Group)

A compression format for color still images. Photographs (images) shot using this camera are

recorded onto the card in JPEG format when the Record mode is set to SHQ, HQ, SQ. By

downloading these images to a personal computer, users can edit them using graphics

application software or view the images using an Internet web browser.

M (Manual) Mode

The user sets both the aperture and shutter speed.

NTSC (National Television Systems Committee) / PAL (Phase Alternating Line)

Television formats. NTSC is mainly used in Japan, North America and Korea.

PAL is mainly used in Europe and China.

Number of Pixels (PIXEL COUNT)

The number of dots (pixels) used to create an image denotes the image size.

For instance, an image in 640 × 480 pixel count is the same size as the computer screen if

the monitor setting is also 640 × 480. If the monitor setting is 1024 × 768, the image only

takes up part of the screen.

P (Program) Mode

Also called Program AE mode. The camera automatically sets the best shutter speed and

aperture for the shot.

PictBridge

A standard that enables digital cameras and printers made by different manufacturers to be

connected, and also allows pictures to be printed directly from the camera.
