Imaging apparatus and processing method thereof

Abstract

An imaging apparatus is provided having: a pixel unit including an effective pixel region of multiple pixels accumulating charges generated according to incident light to output signals and an ineffective pixel region of multiple pixels outputting signals not dependent on incident light; a plurality of vertical signal lines provided for each column of pixels of pixel unit; a vertical scanning circuit that scans and selects pixels of pixel unit in row units to output signals of selected pixels of same row to plurality of vertical signal lines; and a horizontal scanning circuit that scans and selects signals of plurality of vertical signal lines to output signals of selected vertical signal lines; wherein the vertical scanning circuit selects pixels of same row of effective pixel region in row units once during one frame and selects pixels of same row of ineffective pixel region in row units multiple times during one frame.

1 . An imaging apparatus comprising:
 a pixel unit including an effective pixel region of a plurality of pixels accumulating a carrier generated based on an incident light and outputting a signal, and an ineffective pixel region of a plurality of pixels outputting a signal independent of the incident light;   a plurality of vertical signal lines arranged each for each of columns of the pixels of the pixel unit;   a vertical scanning circuit for scanning and selecting row by row, or rows by rows, the pixels of the pixel unit, such that the signal of the pixels of the same selected row is outputted to the plurality of vertical signal lines; and   a horizontal scanning circuit for scanning and selecting the signal of the plurality of vertical signal lines such that the signal of the selected signal line is outputted, wherein   the vertical scanning circuit selects at a single time row by row, or rows by rows, the pixels of the same row of the effective pixel region during a one frame time period, and selects at plural times row by row, or rows by rows, the pixels of the same row of the ineffective pixel region during the one frame time period.
