Test Methods
The following tests are performed with the CCD device to be measured mounted on the Sanyo evaluation board.
1. Sensitivity
Set up a CCV31F pattern box (Dai Nippon Printing Co., Ltd., intensity: 1320 NT, color temperature: 3100°K) with
no pattern, and take an image with C-500 a 1 mm thickness infrared blocking filter mounted in front of a Fujinon
HF16A lens. Set the lens aperture to f11, and set the separation between the lens and the pattern box to be 50 cm.
Measure the CCD output signal from the center of the image in this state.
2. Video signal non-uniformity
Test this item under the following conditions.
Standard drive state (See the specifications document.)
Use a halogen lamp with a color temperature of 3200°K as the light source.
Use an infrared blocking filter (C-500, 1 mm thickness).
Set the CCD surface illumination level to be 7 lux, and divide the screen into 45 blocks as shown in Figure 3.
Measure the average value in each block and determine the maximum, minimum, and mean of those values.
Determine the ratio of the difference between the maximum and minimum of the block averages to the mean of the
block averages.

3. Saturated signal level
In the test method 1 setup state, remove the lens to saturate the output signal. Measure the CCD output signal from
the center of the image at this time.
4. Smear
Place a 1/10 V chart in front of a halogen light source as described below and take the image.
Adjust the image (input) light intensity using ND filters so that the output signal at point A, i.e., the CCD output,
becomes 250 mV.
Remove the ND filter and measure the output value for the first line (at point B) in the CCD output signal.
