Patent ID: 8730346

Claim:
A solid-state imaging apparatus comprising: a pixel unit in which pixels are arranged in a matrix form; an electronic shutter scanning circuit that can control an accumulation time of the pixels for each of adjacent lines of the pixel unit; a flicker correction circuit that corrects flicker generated in a signal imaged in the pixel unit for each line, based on a signal of the pixels of each of the lines in which the accumulation times are different from each other, wherein the flicker correction circuit includes: a light information detection circuit that detects light quantity change information from the signals of the pixels of the different lines; and a level correction circuit that corrects the signal of the pixels for each line, based on the light quantity change information detected by the light information detection circuit; wherein the light information detection circuit includes: a difference signal generation circuit that generates a difference signal between the signals of the pixels of the lines in which the accumulation times are different from each other; a phase detection circuit that detects a phase of the light quantity change information, based on the difference signal; a level detection circuit that detects a level of the light quantity change information, based on the difference signal; and a period determination circuit that determines whether a period of the light quantity change information is 50 Hz or 60 Hz, based on the difference signal, wherein the period determination circuit sets, as a flicker period, a difference between different vertical line numbers in which a signal level of the difference signal is determined to be zero.
