Figure 3.8 Inter-frame timing of W.O.I

3.7.2. Skip_Digital

Sub-sampling ( Skip_Digital ) to VGA ( 640x480 ) pixels readout ( With 4 dark lines ):

H_Start[9:0] = 0,

V_Start[8:0] = 0,

H_Size[9:0] = 1287,

V_Size[8:0]= 1035,

LPF[7:0] = 1036,

Nov_Size_By4[7:0] = 63, Skip_Digital = 1

Valid pixel = ( H_Size + 1 ) / Skip_Digital = 1288 / 2 = 644

Valid line = ( V_Siez + 1 ) / Skip_Digital = ( 1035 + 1 ) / 2 = 518
