Camera Modes of Operation
3.2.5 Delete Last Object - dA/dP/dC
This mode is available with audio record hardware fitted.
If the last object captured was an audio recording, 'dA' (delete audio) is displayed, if the last object
was an image, then 'dP' (delete picture) is displayed, or, if the last object was part of a continuous
capture sequence, then 'dC' (delete continuous) is displayed. If the camera is empty, the mode is
suppressed. The mode works like ‘CL’ (Clear All), that is once the mode is selected, pressing the
shutter button once causes the camera to beep and ‘dA’, ‘dP’ or ‘dC’ to start flashing. Pressing the
shutter button again within 5 seconds deletes the last audio clip, picture or continuous capture
sequence.
3.2.6 Continuous mode - Ct
Pressing the shutter button within 5 seconds causes the camera to start taking pictures for as long
as the shutter button is pressed down (and the camera is not full). If the shutter button is not pressed
within 5 seconds the camera reverts to normal picture taking mode.
Note: 1 In continuous mode, the camera allows pictures to be taken regardless of the available light, which
could result in insufficient exposure.
2 In continuous mode, only every alternate field is grabbed hence capture rate is halved. For example,
12.5fps CIF and 7.5fps VGA
3 Continuous mode is suppressed when the FlashGun enable signal (GPIO2) is high.
3.2.7 Self timer - St
Pressing the shutter button starts a 10-second self-timer. The camera issues a short beep every
second, followed by a longer beep. A further beep will then indicate that the picture has been taken
(high beep - picture successful, low beep - insufficient light, picture not taken). The self-timer mode
cannot be selected when the camera is full. The self-timer count down cannot be stopped once it
has started.
3.2.8 Clearing the camera memory - CL
Pressing the shutter button once causes the camera to beep and the ‘CL’ to start flashing. Pressing
the shutter button again within 5 seconds clears all the images/audio clips in the camera and resets
the counter.
3.2.9 Changing picture resolution - Hr/Lr
The resolution option is displayed, either Hr to change to high-resolution mode (if currently in low-
resolution mode) or Lr to change to low-resolution (if currently in high-resolution mode). Press the
shutter button within 5 seconds to select the resolution option, the camera beeps and the display is
reset, indicating the number of pictures available in the new mode. The picture resolution can be
changed at any time, that is the camera can store both high and low resolution images.
