VISDEFTABLE (Statement)

Function

Reads images on the camera and sets the look-up table data for image output.

Format

VISDEFTABLE <Table number>, <Input value>, <Output value>

Explanation

<Table number> Designates the number of the look-up table (5 to 15).

<Input value> Designates the input value of the table (0 to 255).

<Output value> Designates the output value of the table (0 to 255).

Example of conversion using the look-up table

Note (1): If you do not set this instruction,

the statement follows the

initial setting values.

Note (2): This instruction requires 2 to 3 seconds to complete.

Note (3): Tables considered useful are set for the table numbers 0 to 4

beforehand. With this command,

you cannot edit.

Table 0: Normal (0 to 255)

Table 1: 70% brightness compressed (0 to 175)

Table 2: γ

γγ

γ compensation

Table 3: Reversed

Table 4: 70% brightness compressed and reversed

Note (4): To execute this instruction,

a µ

µµ

µVision board (option) is

required.

Note (5): During execution of this instruction, do not power off the

controller. If you do so, the controller will recognize in the

next powering-on sequence that it has not been normally

terminated, so it will initialize the vision-related information.
