An Over 200-dB Dynamic Range CMOS Image Sensor Combining a Lateral Overflow Integration with Photo-Current Readout Operation
Bibliographic record
Abstract
A wide dynamic range 64x64 CMOS image sensor with 20x20um 2 pixel that combines a lateral-overflow integration voltage-readout operation with the current readout operation from the buried photo-diode hasbeen developed.In the voltage readout operation,an over 160-dB dynamic range image with a linear response isobtained from sequential electronic shutter operations from 1/30 s to 1/130 ks with a dynamic range of about 100-dB within a light intensity range from about 10 -2lx to 106lx.In addition,an over 200-dB dynamic range perform-ance of up to 108lx or more with few time exposures in the high illuminance region is made possible by combiningit with the current reading operation.More than 40 dB for all noises,including photon shot noise,occurs around all the switching points.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
