Patent ID: 8237808

Claim:
A solid-state imaging device comprising: a second row of unit pixels between a first row of the unit pixels and a third row of the unit pixels, each of the rows extending along a horizontal direction; a second column of the unit pixels between a first column of the unit pixels and a third column of the unit pixels, each of the columns extending along a vertical direction; a column processor configured to convert analog signals from each pixel within said first row of the unit pixels into a first row of digital data and to convert analog signals from each pixel within said third row of the unit pixels into a third row of digital data; a digital arithmetic unit configured to produce a center row of digital data by applying a weight value during a weighted row addition, said weight value being applied to said first row of digital data or said third row of digital data, wherein said first row of digital data is added to said third row of digital data during said weighted row addition, a spatial position of the center row being shifted from said second row of the unit pixels in said vertical direction by a ratio of the weight value.
