Abstract:
1. A solid-state imaging apparatus comprising: a solid-state imaging device comprising a pixel section having a plurality of pixels that are two-dimensionally arranged, each having a photoelectric conversion means, an amplification means for amplifying a signal supplied to an input section thereof, a reset means for resetting the input section of said amplification means, and a transfer means for transferring imaging signal generated at said photoelectric conversion means to the input section of said amplification means where an output section of said amplification means of each of the pixels arranged in each column is connected to a common signal line provided for each column, a column processing circuit for suppressing noise of signals from said pixels outputted onto said common signal line, a vertical scanning circuit for controlling by the unit of row said amplification means, said reset means, and said transfer means of said pixels, a horizontal scanning circuit for controlling by the unit of column the outputting of the signals after noise suppression from said column processing circuit to a horizontal signal line, and a mode setting control circuit for effecting drive control in accordance with a set read mode, capable of setting a first read mode for reading said imaging signal out to said horizontal signal line and a second read mode for acquiring correction data for suppressing noise due to said column processing circuit based on a plurality of signals independently read out to said horizontal signal line from said pixel in each of the condition where said input section is reset and the condition where said imaging signal is not retained; a memory for retaining said correction data; and a correction means for correcting said imaging signal read out in said first read mode based on the correction data retained at said memory, wherein said memory retains correction data derived from addition for each column of said correction data of a plurality of rows.
