Overview

This document describes the interfacing and the driving of the image sensor LUPA1300, which is a 1280 by 1024 CMOS pixel array working at 450 frames/sec. The sensor is an active pixel sensor with synchronous shutter. The pixel size is 14 * 14 μm and the sensor is designed to achieve a fame rate of 450 frames/sec at full resolution. This high frame rate can be achieved by 16 parallel output amplifiers each working at 40MHz pixel rate.

The readout speed can be boosted by means of windowed Region Of Interest (ROI) readout. High dynamic range scenes can be captured using the double slope functionality.

The sensor uses a 3-wire Serial-Parallel (SPI) interface. It is housed in a 145-pin ceramic PGA package.

Main features

The main features of the image sensor are identified as:

? SXGA resolution: 1280 x 1024 active pixels.

? 14 μm2 square pixels (based on the high-fill factor active pixel sensor technology of FillFactory (US patent No. 6,225,670 and others)).

? Pixel rate of 40 MHz using 16 parallel outputs.

? Random programmable windowing.

? Dual slope integration possible

? 145-pin PGA package

? Peak QE x FF of 15.

? Optical format: 1,43” (17.9 mm x 14.3 mm)

? Optical dynamic range: 62 dB (1330:1) in single slope operation and 80…100 dB in double slope operation.

? 16 parallel analog output amplifiers.

? Synchronous pipelined shutter.

? Processing is done in a CMOS 0.50 μm triple metal process.
