Integration Time for Interlaced HDR Readout
Integration Time for Interlaced HDR Readout
Tint1 (integration time 1) and Tint2 (integration time 2)
The limits for the coarse integration time are defined by:
coarse_integration_time_min  coarse_integration_time  frame_length_lines – coarse_integration_time_max_margin
(EQ 4)
coarse_integration_time2_min  coarse_integration_time2  frame_length_lines – coarse_integration_time2_max_margin (EQ 5)
The actual integration time is given by:
integration_time
=
_{---c---o---a---r--s--e---_---i--n---t-e---g---r--a---t--i--o---n---_---t-i--m----e----}_{-----l--i--n---e--_---l--e---n---g---t-h---_---p---c---k---}
vt_pix_clk_freq_mhz  10⁶
(EQ 6)
integration_time2 = ^---c---o---a---r--s--e---_---i--n---t-e---g---r--a---t--i--o---n---_---t-i--m----e---2-----^----l--i--n---e--_---l--e---n---g---t-h---_---p---c---k---^
vt_pix_clk_freq_mhz  10⁶
(EQ 7)
If this limit is broken, the frame time will automatically be extended to
(coarse_integration_time + coarse_integration_time_max_margin) to accommodate the
larger integration time.
The ratio between even and odd rows is typically adjusted to 1x, 2x, 4x, and 8x.
