- Selectable 9-point AiAF and single-point AF (range frame can be set arbitrarily)

The AiAF range frame for the IXY DIGITAL 320 has been increased from the previous 3 points (IXY DIGITAL 200a) to 9 points. As a result, framing unconstrained by the position of

the subject is possible. With multiple focus points, the respective range

frames for the focus points are displayed in green (when there are two or more focus points, the range frames for all focus points are shown).

IXY DIGITAL 320 also employs standard AF system that use

AF frame with a single center point, so that user can choose the

convenient method depending on photographic conditions.

- Settable display times for rec review (2 to 10 seconds)

The Ixy digital 320 is specified so that the image-display time* in rec review (confirmation of recorded image) can be set between two and 10 seconds in 1 second intervals. In this way, users can select a duration to suit their applications.

*“Off” can also be set

-Continuous movie recording and playback with audio with long filming times (3 minutes) (selectable from QVGA and QQVGA)

The Ixy digital 320 can record moving images at 15 frames per second along with audio in 2 formats, QVGA (320 by 240 pixels) and QQVGA (160 x 120 pixels). Because a method is employed that consecutively writes images that are temporary stored in the buffer to the CF card while recording, long continuous filming times are also achieved.

In practice, if the write speed of the CF card is slower*1 than the speed to write an image to the buffer, the recording will stop when the buffer capacity is reached. Taking this circumstance into account, the specification limits the maximum recording time in both QVGA and QQVGA formats to three minutes. Even after three minutes of elapsed filming, the G3 allows the next recording to be resumed in less time than previous models.

During filming, the values for the focus, exposure, white balance and zoom position determined at the beginning are used continuously to the end of the recording. The storage time is also displayed on the LCD monitor during filming.

The file is saved in AVI format, while the image is saved as Motion JPEG data and the audio data in WAVE format (mono).

*1 The write speed varies depending on the brand and capacity of the CF card.

*2 If the free space on the CF card is less than the size of the recording, recording will stop just prior

to the CF card reaching full capacity.
