3. Basic operations

3-12. SD memory cards

The unit’s frame memory data and system data can be stored on SD memory cards.
Conversely, this data can be loaded from the SD memory cards to the unit.

Frame memory data (still image data):

The unit supports 24-bit (uncompressed) BMP (bitmap) and JPEG (baseline) is the only file formats.

JPEG format files can be loaded, but they become BMP format files when they are stored from the unit to the
SD memory card.

This unit cannot resize the images so resize them appropriately using another device such as a personal
computer before saving them on the SD memory card.
<Applicable sizes>

HD/1080i: 1920

1080, HD/1080psf: 19201080, HD/720p: 1280720,

SD/NTSC: 720

487, SD/PAL: 720576

BMP files:
If the sizes are different, the center of the images will be lined up.
If the image is large, it will be cropped.
If the image is small, the area around it will be filled in with a black border.
JPEG files:

Images in the sizes listed in “Applicable sizes” above can be loaded.

The pixels of images in SD format are not square, so the aspect ratio will be different when the images are
displayed on the computer and when they are imported into frame memory (with NTSC format, they will be
vertically long).
To keep the images true to their actual proportions, make sure the original size is 720

540 pixels. If the

images are in NTSC format, use images shrunk to 720

487 pixels. If the images are in PAL format, use

images enlarged to 720

576 pixels.

System data:

The “system data” refers to all the data stored in the unit with the exception of the date, time and network
settings and of the still image data. The extension used for the system data files is “h45”.

SD memory card handling precautions
 Do NOT eject the SD memory card while the SD memory card access LED is lighted.
When an SD memory card is ejected while the SD memory card access LED is lighted, the transition of the

operation from data access to card ejection may be temporarily suspended.
In addition, the data stored on the SD memory card may be lost.

 The data stored on SD memory cards may be lost as a result of misplacing the cards or performing erroneous

operations, for instance. It is recommended that valuable data be stored on a personal computer or other
device.
