Equation 9:

��ℎ��_�� = 32 ∗ ��_��

Disabling shutter lag is not possible in the 10-bit short exposure more (IMG.2) and the 12-bit short

exposure mode (IMG.5).

Description

ROW_LENGTH

18-19

[13:0]

See below

The row length trow defines the DVAL frequency during readout; it can be programmed in number of

CLK_PIX cycles with the ROW_LENGTH register.

The row length has a minimum value because a number of parallel processes in the sensor need to

be completed within one row time. The minimal row length depends on the number of outputs used

(see equations in section 7.4.3).

The maximal row length value is only constrained by the 14 bits size of register.

Fine frame rate adjustments are done through external timing or with the FRAME_TIME register.

Changing the row length only influences the DVAL frequency within a readout sequence. This can be

useful when smaller or slower row buffers are used in the external system.

An exception to this rule is the in-line streaming mode, where the ROW_LENGTH register does

directly alter the frame rate.

7.5.3

Vertical Windowing

The sensor supports multiple windows in the vertical direction to create regions of interest (ROI).

Row Addressing

As introduced in section 7.1.1, the sensor has buffer pixels rows above and below the effective pixels.

Every row in the array is paired with a physical row address. This row address is used to specify

vertical ROI positions as described in next section.

Row addresses are assigned in ascending order starting from 0 for the row closest to the package pin

row 1.
