ABSTRACT:
Solid state imaging devices include an image sensor having a two-dimensional matrix of picture elements arranged horizontally and vertically. A vertical scanning circuit selects horizontal lines of picture elements within the two-dimensional matrix in a predetermined order for reading the picture elements. A horizontal scanning circuit coupled with a plurality of vertical lines joining vertically spaced ones of the picture elements serves to select picture elements in the horizontal lines selected by the vertical scanning circuit to output image signals therefrom. The horizontal scanning circuit is operative to scan the picture elements of the selected horizontal lines through one side of the two-dimensional matrix in a first horizontal direction to output a normal image signal. The horizontal scanning circuit is also operative to scan the picture elements of the selected horizontal lines through the same horizontal side of the two-dimensional matrix in a second horizontal direction opposite the first horizontal direction to output a mirror image signal. Methods of reading a solid state imaging device to produce normal and mirror image signals therefrom include the steps of scanning a two-dimensional matrix of picture elements at a first side in a first direction to output a normal image signal and scanning the matrix at the first side in a second direction opposite the first direction to output a mirror image signal.
