PHOTOELECTRIC CONVERSION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240284066 titled 'PHOTOELECTRIC CONVERSION DEVICE
Simplified Explanation: The patent application describes a photoelectric conversion device that can switch between two operation modes to output signals based on charges generated in photoelectric conversion units. The device corrects output signals from different pixel rows using correction values obtained from signals read in each operation mode.
- First driving for outputting a signal based on a sum of charges generated in photoelectric conversion units
- Second driving for outputting a signal based on charges generated in one photoelectric conversion unit
- Switchable operation modes for reading signals from pixel rows
- Correction of output signals based on signals read in different operation modes
Key Features and Innovation:
- Ability to switch between operation modes for signal output
- Correction of output signals based on signals read in different modes

Original Abstract Submitted
a photoelectric conversion device can execute a first driving for outputting a signal based on a sum of charges generated in photoelectric conversion units and a second driving for outputting a signal based on charges generated in one photoelectric conversion unit. a first operation mode in which a signal is read from a pixel of one row by the first driving and a second operation mode in which a signal is read from a pixel of one row by continuously performing the first driving and the second driving are switchable for each row. an output signal of a first pixel row is corrected based on a first correction value based on an output signal of a second pixel row read in the first operation mode and a second correction value based on an output signal of the second pixel row read in the second operation mode.
