The iCAM501U will still store the picture even if it is flagged up as being of poor

quality. The reason for this is that factors such as the lighting conditions may mean it

is not possible to get a perfect picture and a poor one is better than no picture.

However it is strongly recommended that another picture is taken.

If the flash is required when taking a picture in low lighting conditions, turn the flash

on as indicated in the above section and wait until the red LED stays constantly on.

Note the flash can take up to 20 seconds to fully charge when the batteries are part

used. Once the red LED has turned solid the iCAM501U is then ready to take a

picture in the same way as if the flash was not enabled (the flash will automatically

trigger when the picture is being taken).

2.5.4 Image blur analysis feature

The iCAM501U firmware has an additional image blur analysis feature. Images are

analysed for characteristics of blurring, and given a score, which is in turn compared

with a threshold based on the average light level in the image. Good or bad images

are indicated using the LED sequence previously described in Table 1 and Table 2.

However, the reliability of the image analysis function is dependent on the nature of

the scene being photographed. Images which contain little or no details such as

edges (for example a blank wall) may be indicated as blurred when they are in-fact

acceptable. Therefore the user should bear this limitation in mind when taking

pictures, and it is suggested that users should take some practice shots to get a ‘feel’

for the way in which this software behaves.

Note that the iCAM501U also has an anti-shake function. It takes four pictures and

then selects the best quality one to save to the flash memory. This is the reason that

the flash fires 4 times. This operates independently of the image blur analysis

feature, which examines the best of the 4 images taken.
