Abstract
A monochrome or color imager having interlaced, non-interlaced or pseudo-interlaced readout utilizing pixels arranged in groups forming equilateral triangles which are interleaved. Separate vertical shift registers driven by different clock signals to implement different forms of interlaced, non-interlaced and pseudo interlaced signal readout are located on each side of the rectangular array and are coupled to alternating row address lines and different groups of column lines in the array. The clock signals driving each shift register can be controlled to select monochrome or color operation in one of the above noted modes of readout. A horizontal shift register is connected to the gates of MOS coupling transistors which couple the column or bit lines of the array to a pair of monochrome outputs, while a second shift register is connected to the gates of MOS coupling transistors which couple the column or bit lines of the array to a trio of color outputs for color output signals. Either horizontal shift register can be disabled while the other is operating to enable either color or monochrome operation. For color operation a color separation filter must be added thereby preventing …
