Document Type and Number:
Japanese Patent JP7286431
Kind Code:
B2
Abstract:
A photoelectric conversion apparatus includes a plurality of pixels, a generation unit configured to generate a first reference signal changing in potential in a first period from a first point in time to a second point in time, and a second reference signal having a gradient larger than a gradient of the first reference signal and changing in potential in a second period from a third point in time to a fourth point in time, and a plurality of analog to digital (AD) conversion units. Each of the AD conversion units includes a selection circuit configured to select the first reference signal or the second reference signal, and a comparator. The first period and the second period partially overlap with each other. The third point in time is later than the first point in time.
