Sony patents camera sensor fix for mixed signal noise
Sony describes a camera sensor design that captures both standard image frames and specific light changes simultaneously. The system detects when these two data streams overlap and interfere with each other, then adjusts the data to remove the resulting noise.
In the filing’s own words
The present technology relates to a light detection device, a correction method, and a program that can reduce effects of interference between a gradation signal and an event signal. The present technology includes a pixel array section including a plurality of pixels disposed in a two-dimensional matrix, the pixel including an event data generation section configured to detect, as an event, a change in luminance of incident light in the same direction and generate event data based on the event that is detected and a gradation data generation section configured to generate gradation data that is data corresponding to the luminance of the incident light; an interference intensity identification section configured to identify an intensity of interference generated by an overlap between a period in which the gradation data is generated and a period in which the event is detected; and a correction section configured to correct the event data according to the intensity of the interference identified by the interference intensity identification section. The present technology can be applied to, for example, a light detection device that acquires a gradation signal and an event signal.
What exactly they claim (claim 1)
1. A light detection device comprising: a pixel array section including a plurality of pixels disposed in a two-dimensional matrix, the plurality of pixels each including an event data generation section configured to detect, as an event, a change in luminance of incident light in the same direction and generate event data based on the event that is detected and a gradation data generation section configured to generate gradation data that is data corresponding to the luminance of the incident light; an interference intensity identification section configured to identify an intensity of interference generated by an overlap between a period in which the gradation data is generated and a period in which the event is detected; and a correction section configured to correct the event data according to the intensity of the interference identified by the interference intensity identification section.
