Hi, I am using the e-puck 1176 (VGA camera 480x640 - rotated camera).
I am capturing some full (480 pixels) horizontal lines (1 to 8 lines) applying the zoom factor of 1, 2, 4 and 8 (on the x component which in this epuck camera is the vertical component). I assume that if I am capturing 4 horizontal lines with zoom 2 its the same of capturing 8 lines with zoom 1 (and so one). The zoom just does the line averaging within groups of 2 lines. When I capture the images I am using a timer (TIMER1) to quantify the capture duration. After my experiments from capturing 1 - 8 lines with zoom 1,2,4,8 I have concluded that the capture time is approximatly constant (between 350 and 450), no matter the number of lines we take and the zoom we do. I have also witnessed a large Jitter between frame captures (the standard deviation of the frame capture times is arround 150ms!). I was expecting a rise of time when I extracted more lines and no Jitter should exist. Could someone tell me what I could be the cause of this behaviour (expecially the Jitter behaviour).
