Imaging Characteristics at Ta = 25°C

Note: 1. When the frame shift frequency is 3.55 MHz and the storage time is 1/50 second.

Test Procedures

The Sanyo evaluation board must be used for the following tests.

1. Sensitivity

Use a CCV31F pattern box (manufactured by Dai Nippon Printing Co., Ltd.) set up at a brightness of 1500 NT and

color temperature of 5100°K with no pattern. Image the pattern box with an HF16A lens (manufactured by Fujinon)

with a 1 mm thick C-500 IR cut filter in front of that lens.

Set the lens f-stop to f8 and set the lens to be 50 cm from the pattern box. Measure the CCD output signal from the

center of the image with this setup.

2. Uniformity of Output Signal

Measure under the following conditions.

• Standard drive conditions (See the specifications document.)

• Use a 3200°K color temperature halogen lamp as the light source.

• Use a 1 mm thick C-500 IR cut filter.

Set the CCD surface illumination to 7 lux, and divide the image into 45 areas as shown in Figure 4.

Measure the average value for each block, and determine the maximum, minimum, and mean of those values.

Determine the ratio of the range of the block average values to the mean of the block average values.

3. Saturated Signal

Saturate the output signal by removing the lens in the test setup for item 1. Measure the CCD output signal from the

center of the image in this state.
