1/7 Inch 110 k Pixel CMOS B/W Image Sensor
The TCM5020ALU is a CMOS b/w (= black and white) image
sensor that meets with CIF format. It enables all pixel signals to
be output in sequence each 1/30 s. (progressive scanning)
This element is equipped with 290 vertical and 367 horizontal
signal pixels, and the image size meets with 1/7 inch optical
format. The package with lens is applicable. This small lens unit
package realize small-scaled system.
Use of the CMOS process enables low power-consumption
operations with a single power voltage driving. It is perfect for
use as an image input device for mobile equipments.
Features
• Optical size: 1/7 inch optical format
• Total pixel numbers: 382 (H) × 306 (V)
• Signal pixel numbers: 367 (H) × 290 (V)
• Pixel pitch: 5.6 µm (H) × 5.6 µm (V) (square pixel)
• Image size: 2.055 mm (H) × 1.624 mm (V)
• Package: 16-pin Optical lens unit
• Frame frequency: 30 Hz
• Power voltage: 2.8 V
• Additional functions: Variable electronic shutter (1/30 to 1/4500 s)
