... Sensor Architecture The LUPA 4000 architecture is shown in Image Core The image core consists of a pixel array, one X-addressing and two Y-addressing registers (only one drawn), pixel array drivers, and column amplifiers. The active pixel area is read out in progressive scan by one or two output amplifiers. The output amplifiers operate at a nomimal ...

... SPI. Analog-to-Digital Converter The LUPA 4000 has two 10-bit flash ADCs running nominally at 10 Msamples/s. The ADC block is electrically separated from the image sensor. The inputs of the ADC must be tied externally to the outputs of the output amplifiers ...

... FOT Handling ROT Document Number: 38-05712 Rev. *F Operating Modes The LUPA 4000 sensor operates in the global shutter mode. Global Shutter Mode In the global shutter mode, light integration takes place on all pixels in parallel, although subsequent readout is sequential. Figure 8 synchronous shutter. All pixels are light sensitive at the same period of time. The whole pixel core is reset simultaneously ...

... The voltage supplies Vpix and Vaa must be noise free. Startup Sequence The LUPA 4000 goes in latch-up (draw high current) when all power supplies are turned on simultaneously. The sensor comes out of latch-up and starts working normally as soon clocked ...

Biasing and Analog Signals The expected analog output levels are between 0.3 V for a white, saturated, pixel and 1.3 V for a black pixel. There are two output stages, each consisting of two output amplifiers, resulting in four outputs. ...
Page 11
In Figure 11, levels are defined by the pixel array voltage supplies; for correct polarities of the signals see signals in Figure 11 are generated from the on-chip drivers. These on-chip drivers need two types of signals to generate the ...

... To acquire a frame rate of 15 frames/sec, the output amplifier should run at 66 MHz pixel rate or two output amplifiers should run at 33 MHz each, assuming an ROT of 200 ns. The frame period of the LUPA 4000 sensor is calculated as follows: Frame period = FOT + (Nr. Lines × (ROT + pixel period × Nr. ...

... Timing and Readout of Image Sensor The timing of the LUPA 4000 sensor consists of two parts. The first part is related to the control of the pixels, the integration time, and the signal level. The second part is related to the readout of the image sensor. As full synchronous shutter is possible with this image sensor, integration time and readout can be in parallel or sequential ...

X and Y Addressing To read out a frame, the lines are selected sequentially. Clock_y and Sync_y signal. The Sync_y signals synchronises the y-addressing and initialises the y-address selection registers. The start address is the address downloaded in the SPI ...
Page 16
The figure shows Clock_x, Sync_x, internal selection pixel 1 and 2, internal selection pixel 3 and 4, internal selection pixel 5 and 6. The first pixel selected is the x-address downloaded in the SPI. The starting address is the number ...
