By convention, the MT9V012 pixel array is shown with pixel (0,0) in the top right-hand
corner (see Figure 5). This reflects the actual layout of the array on the die. When the
sensor is imaging, the active surface of the sensor faces the scene, as shown in Figure 6.
When the image is read out of the sensor, it is read one row at a time, with the rows and
columns sequenced as shown in Figure 5. By convention, data from the sensor is shown
with the first pixel read out—pixel (34,14) in the case of the MT9V012—in the top left-
hand corner (Figure 7).
The MT9V012 image data is read out in a progressive scan. In default mode, valid image
data is surrounded by horizontal blanking and vertical blanking, as shown in Figure 7.
The amount of horizontal blanking and vertical blanking is programmable; LINE_VALID
is HIGH during the shaded region of the figure. FRAME_VALID timing is described in the
next section.
