Moving object, hand blurring

The Imager requires a certain amount of exposure time for image capturing. This means that if the

subject is moving during this interval, the resultant image will be blurred. Therefore, if you need

to capture a symbol while looking for its location, it is advised to adjust the Imager to the location

of the symbol with the aimer LED, then perform reading with the Imager held still so that the

objective symbol, as well as the resulting image of the symbol, is also still relative to the Imager.

Sensitivity and noise

Due to the nature of CMOS sensor, it has poor sensitivity and the image is easily affected by noise.

In particular, this is significant when image capturing is attempted in a dark place or the subject is

far from the Imager.

Tips to optimum image capturing

• Always keep the Imager filter clean.

• Remember that the optimum image capturing distance is around 18 cm.

• As much as possible, capture a symbol in a location where the variation in ambient light is

small.

• Hold the terminal so it is inclined 30 degrees inward and so that the symbol can be seen in a

position slightly above the terminal.

• To read a symbol, first adjust the Imager position with the aiming LED and then begin

capturing by holding the terminal still (fixed).

• In a dark location it is advisable to capture within the effective coverage of the illumination

LED while ensuring sufficient illumination for the distance area.
