DETECTING APPARATUS, IMAGE PICKUP APPARATUS, AND DETECTING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18526741 titled 'DETECTING APPARATUS, IMAGE PICKUP APPARATUS, AND DETECTING METHOD
The patent application describes a detecting apparatus that performs focus detection and flicker detection using signals obtained from an image sensor, and controls signal readout from the sensor.
- The apparatus switches between a first readout state for generating focus detecting signals from each of the first and second pixels, and a second readout state for generating focus detecting signals from a focus detecting pixel and flicker detecting signals from a flicker detecting pixel.
- The focus detecting pixel and flicker detecting pixel are different from each other and from the first and second pixels.
- This technology enables efficient focus and flicker detection in image sensors, improving overall image quality and performance.
Potential Applications: - Camera systems - Surveillance systems - Medical imaging devices
Problems Solved: - Improved focus detection accuracy - Enhanced flicker detection capabilities - Optimal signal readout control

Original Abstract Submitted
A detecting apparatus performs focus detection using a pair of focus detecting signals obtained from an image sensor, detects flicker using a flicker detecting signal obtained from the image sensor, and controls signal readout from the image sensor. The detecting apparatus switches between a first readout state for performing signal readout for generating the pair of focus detecting signals from each of the first pixel and the second pixel, and a second readout state for performing signal readout for generating the pair of focus detecting signals from a focus detecting pixel as the first pixel and for performing signal readout for generating the flicker detecting signal from a flicker detecting pixel that is either the first pixel or the second pixel and is different from the focus detecting pixel.
