The LS4k is a high speed CMOS System on Chip (SoC) line scan image sensor optimized for applications requiring short exposure times and high accuracy line rates. It incorporates on chip two pixel arrays consisting of 2 rows with 4,096 7μm pitch pixels and 4 rows with 2,048 14μm pitch pixels respectively, a high accuracy (12-bit) high speed (84MHz) analog-to-digital conversion (ADC), and sophisticated on chip optical calibration for PRNU, DSNU, and lens shading correction.
