HP 912 Digital Camera User’s Guide 132 Glossary
Program exposure mode
The exposure mode where the camera selects an appropriate aperture and shutter speed. However, you
can change or override all settings. See also “exposure modes” on page 127.
protect
Marking an image so that no one can delete it.
record button
See “sound record button” on page 133.
red-eye
Refers to a human’s or animal’s eyes that appear red in captured images, which is caused by using the
flash on a camera.
red-eye reduction
A flash mode you can use to minimize red-eye in captured images of humans or animals. The camera
does this by flashing twice. See also “flash mode” on page 127.
reformat
Reformatting completely erases the memory card, including all images (protected and unprotected) and
all other files.
remote controller
A device used to trigger the shutter from a location that is remote from the camera, such as when you want
to take a self portrait or want to be in a group picture. When you press the remote trigger, the image
capture is delayed by a length of time specified by the timer mode. See also “timer mode” on page 134.
resolution
The measure of how many pixels are displayed or printed. The resolution of a CCD is determined by
multiplying the X pixels by the Y pixels. The greater the resolution, the greater the amount of detail
visible, and the larger the file size. The final output device (computer monitor or printer) on which an
image is displayed or printed determines the actual resolution you will see. For example, if you capture an
image at 1600 x 1200 pixels, and your printer is capable of printing at only 300 dpi (dots per inch), the
printed image will be no more than 300 dpi.
review
The process of using the image LCD to view the images stored on the memory card.
Review mode
An operational mode you can use to sort and edit the captured images on the camera, and to print photos
of the images. See also “camera mode dial” on page 126.
self-timer
See “timer” on page 134.
Send button
A button on the back of the camera you can use to send images from the camera to a printer via the
HP JetSend infrared technology. The Send button is active in the Capture, Review, and Playback modes.
See also “JetSend” on page 129.
shutter
A set of surfaces that block light from the film or CCD in a camera. When the shutter is released, the
surfaces open for a predefined time, admitting a measured amount of light. See also “CCD” on page 126.
Shutter Priority (Tv) exposure mode
The exposure mode that lets you select a shutter speed, and the camera automatically selects the
aperture setting. See also “aperture” on page 125, “Aperture Priority (Av) exposure mode” on page 125,
“exposure modes” on page 127, “shutter” on page 132, and “shutter speed” on page 133.
