WOI is defined using the WOI Pointer, WOI Depth, and

WOI Width registers, (

Table 29 on page 35

through

Ta-

ble 36 on page 37

). Please refer to

Figure 6

for a picto-

rial representation of the WOI within the active pixel

array.

Figure 6. WOI Definition

2.1.6 WOI Sub-sampling Control

The WOI can be sub-sampled per user control. The

user can read out the pixel data in either monochrome

or bayer pixel space in four different sampling rates in

each direction: full, 1/2, 1/4, or 1/8. The user controls

the subsampling via the

Sub-sample Control Register,

(Table 25), on page 32

. An example of Bayer space

sub-sampling is shown in

Figure 7

Figure 7. Bayer Space Sub-sampling Example

2.1.7 CFCM Frame Rate and Integration Time

Control

In addition to the minimum time required to readout the

selected resolution and WOI, the user has the ability to

control the frame rates while operating in CFCM. This is

done by varying the size of a Virtual Frame surrounding

the WOI. Please refer to

Figure 8

for a pictorial descrip-

tion of the Virtual Frame and its relationship to the WOI.

Figure 8. Virtual Frame Definition

The frame rate (time required to readout an entire frame

of data plus the required boundary timing) is completely

defined by the size of the Virtual Frame and can be ex-

pressed as:

Frame Time = vrd

* T

row

+ T

for T

row

< T

lim

Frame Time = (vrd

+ 1) * T

row

for T

row

> T

lim

where vrd

defines the number of rows in the virtual

frame. The user controls vrd

via the CFCM Virtual

Frame Row Depth registers (

Table 40 on page 39

and

Table 41 on page 40

Row Time (T

row

) is the length of time required to read

one row of the virtual frame and can be defined as:

row

= (vcw

+ shs

+ shr

+ 19) * MCLK

period

where vcwd defines the number of columns in the virtual

frame and shs

and shr

are internal timing control reg-

isters. The user controls vcw

via the CFCM Virtual

Frame Column Width registers (

Table 42 on page 40

and

Table 43 on page 41

). The user controls the shs

and shr

values via the

Internal Timing Control Register;

Table 28

and is strongly encouraged to write an 00

this register.

lim

is the minimum amount of time required for the in-

ternally generated frame clamp signal and is defined as:

lim

= 719 * MCLK

period

is the minimum amount of time required to perform

a frame clamp with timing overhead and is defined as:

= (719 + shs

+ shr

+ 19) * MCLK

period
