The figures below give two subsampling examples (skip 4x and skip 2x) in advanced mode.

Sub_s = 0

Sub_a = 4

Number_lines = sum of red lines

Sub_s = 0

Sub_a = 2

Number_lines = sum of red lines

FIGURE 38: SUBSAMPLING EXAMPLES IN ADVANCED MODE (SKIP 4X AND SKIP2X)

5.6 NUMBER OF FRAMES

When internal exposure mode is selected, the number of frames sent by the sensor after a frame request can be

programmed in the corresponding sequencer register.

Number of frames

Default value

Description of the value

Number_frames

55-56

The value in this register defines the number of frames

grabbed and sent by the image sensor in internal exposure

mode (min =1, max = 65535)

5.7 OUTPUT MODE

When LVDS output mode is selected, the number of LVDS channels can be selected by programming the appropriate

sequencer register. The pixel remapping scheme and the read-out timing for each mode can be found in section 4 of

this document.

When parallel CMOS output mode is selected, the Output_mode register should be fixed to 3. Also register 69 has to be

set at 9 and pin B2 connected to ground. The read-out timing for this mode can be found in section 4 of this document.

Output mode

Default value

Description of the value

Output_mode

57[1:0]

0: 4 outputs (LVDS)

2: 2 outputs (LVDS)

3: 1 output (LVDS or parallel CMOS)

5.8 TRAINING PATTERN

As detailed in section 4.1.5, a training pattern is sent over the LVDS data channels whenever no valid image data is sent.

This training pattern can be programmed using the sequencer register.

Training pattern

Default value

Description of the value

Training_pattern

61-62[3:0]
