Olympus Stylus 400 Digital 入門マニュアル

The camera’s built-in exposure meter automatically sets the exposure.

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.

A standard for image files by the Japan Electronics and Information 
Technology Industries Association (JEITA).

This determines the exposure by metering and calculating the light levels in 
the center and other areas of the image separately.

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.

The number of pixels used in the CCD to create the image.

A system for measuring exposure. EV 0 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.

The amount of light used to capture an image. The exposure is determined 
by the time the shutter is open (shutter speed) and the amount of light that 
passes through the lens (aperture).

The total number of pixels in a CCD. Not all pixels are used to create the 
image.
