1. Problem 22.14 (10 points)
A digital camera that uses a CCD image sensor has a 1024 × 768
pixel matrix. The analog-to-digital converter takes 0.05 μ-sec
(0.05 × 10-6 sec) to convert the analog charge signal for each
pixel into the corresponding digital signal, including the time to
switch between pixels. Determine (a) how much time is required to
collect the image data for one frame, and (b) is this time
compatible with the processing rate of 30 frames per second?
2. Problem 22.16 (10 points)
A digital camera that uses a CCD image sensor is to have a 1035
× 1320 pixel matrix. An image processing rate of 30 times/sec must
be achieved (0.0333 sec per frame). To allow for time lost in other
data processing per frame, the total ADC time per frame must be 80%
of the 0.0333 sec. In order to be compatible with this speed, in
what time period must the analog-to-digital conversion be
accomplished per pixel?
3. Problem 22.18 (10 points)
Triangulation computations are used to determine the distance of
parts moving on a conveyor. The setup of the optical measuring
apparatus is as illustrated in the text in Figure 22.14. The angle
between the beam and the surface of the part is 30°. Suppose for
one given part passing on the conveyor, the baseline distance is
7.500 in, as measured by the linear photosensitive detection
system. What is the distance of this part from the baseline?
