Decoding of the first line info block

Serial number

Structure

The serial number consists of two parts.

Decoding

The decoding of the serial number is:

The first part of the serial number S₁ = P_x1 × 256 + P_x2

The second part of the serial number S₂ = P_x3 × 256 + P_x4

Example

S₁ = 156 × 256 + 64 = 40000

S₂ = 0 × 256 + 157 = 157 

Example: decoding of SN: 40000-00157

Image count

Structure

Decoding

The decoding of the image count is:

I_c = P_x6 × 256 + P_x7

Example

I_c = 1 × 256 + 120 = 376

Example: image count 376

Exposure time

Structure

Decoding

The decoding of the exposure time is:

E_t = (P_x8 × 256 + P_x9) / f_a

f_a (10k, 15k) = 50 Mhz

f_a (8k) = 80 Mhz

Example

E_t = (5 × 256 + 220) / 50 = 50 µs

Example: Decoding of exposure time

Line time

Structure

Decoding

The decoding of the Line time is:

L_t = (P_x11 × 2¹⁶ + P_x12 × 2⁸ + P_x13) / 100

Example

L_t = (0 × 2¹⁶ + 21 × 2⁸ + 124) / 100 = 55 µs

Example: Decoding of line time

Encoder clocks

Structure

Decoding

The decoding of the encoder clocks is:

E_c = P_x14 × 2³² + P_x15 × 2¹⁶ + P_x16 × 2⁸ + P_x17

Time stamp

Structure

Decoding

The decoding of the time stamp is:

T_s = (P_x19 × 2¹⁶ + P_x20 × 2⁸ + P_x21) / 4
