Command Descriptions

 

28H:

 

[Delay time for the trigger] Initial Data: DLY[70]

= 0, Data Range: 0 to 65,535

DLY[70]

 

Sets the delay time from the trigger input signal to the start of the exposure.

29H

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DLY[15...8]

 

At 90 fps: Delay time (us) = 74 x 0.0271606 * DLY[70] = 2.0099 (us) * DLY[70],

 

 

At 60 fps: Delay time (us) = 74 x 0.0407408 * DLY[70] = 3.0148 (us) * DLY[70],

 

 

At 30 fps: Delay time (us) = 74 x 0.0814816 * DLY[70] = 6.0296 (us) * DLY[70],

 

 

where CLK = pixel clock.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

30H

 

[CDS gain] Initial Data: PGA[70] = 0, data range:

0 to 255

 

PGA[70]

 

Sets the CDS gain (programmable analog gain).

 

 

 

 

 

 

CDS gain (dB) = ( (PGA[7..0] + GOFS[7..0] ) * 2 * 0.0351) + 6

 

 

 

*GOFS[7...0]: The gain offset (The value of the address 32H)

 

 

 

 

 

 

 

 

 

 

 

 

 

31H

 

[Digital gain] Initial Data: The factory adjusted value, data Range: 0 to 255

 

DGB[70]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Output level = (input level

CLAMP[70]) * (1 + D

 

GB[7..0] / 128) + clamp level

 

 

*CLAMP[7...0]: clamp level (The value of the address 38H)

 

 

 

 

 

 

 

 

 

 

 

 

 

32H

 

[Gain offset] Initial Data: The factory adjusted value, data range: 0 to 255

 

GOFS[70]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

38H:

 

[Clamp level] Initial Data: CLAMP[70] = 9, Data Ra

nge: 0 to 255

 

CLAMP[70]

 

Sets the clamp level value of the black level.

 

 

 

 

 

 

At 12bit output: Clamp level = CLAMP[70] x 8 + 56

 

 

 

At 10 bit output: Clamp level = (CLAMP[7...0] x 8 + 56) / 4

 

 

 

At 8bit output: Clamp level = (CLAMP[7...0] x 8 +

56) / 16

 

 

 

 

 

 

 

 

 

 

 

 

 

3EH: TP0[70]

 

[Test pattern level] Initial data: 768 (300H), data range: 0 to 1023

 

3FH:TP0[98]

 

Sets the output level of the test pattern 4: Raster (variable level) in 10bit output format.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

54H:

 

[Delay time (us) for the strobe signal]

 

 

 

 

 

 

STRBDLY[7..0]

 

Initial data: STRBDLY[23..0] = 0, data range: 0 to 2,000,000

STRBDLY[23..16]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

58H:

 

[Strobe signal polarity] Initial data: IOSIGNAL_POL[7..0] = 00H,

 

STRBPOL[7..0]

 

Sets the strobe signal polarity.

 

 

 

 

 

 

 

 

 

D[7..0]
