Solid state color imaging apparatus

Claim 2

A solid state color imaging apparatus comprising: a solid state image sensor comprising a plurality of picture elements regularly disposed in two-dimensional patterns, the disposition comprising a plurality of horizontal lines, each having a plurality of picture elements disposed in repetition at a predetermined pitch, a color filter comprising a plurality filter elements disposed in regular repetition in horizontal lines and in vertical rows, which-comprises: a first horizontal line (n-th) of filter elements for spatially modulating a first color light (B) and a second color light (G) and a second horizontal line ((n+l)-th) of filter elements for spatial modulating said second color light (G) and a third color light (R), said first horizontal line and said second horizontal lines forming alternate vertical repetitions, and sums of levels of low frequency components of said first line and said second lines being made equal.

Claim 3

A solid state color imaging apparatus in accordance with claim 1, wherein in one horizontal line, a first equivalent picture element is divided into two segments wherein its one segment is covered with a first filter element (MG) and the other segment is covered with a second filter element (CY), thereby making a first segmented filter element (MG+CY), and a next equivalent picture element is wholly covered with a third filter element (YE) and half of said next equivalent picture element is covered with said second filter element (CY), thereby making a second segmented filter element (G+YE), the above disposition is repeated in the horizontal line, in the next horizontal line, a first equivalent picture element which is immediately under said first equivalent picture element of said one horizontal line is divided into two segments wherein its one segment is covered with said first filter element (MG) and the other segment is covered with said third filter element (YE), thereby making a third segmented filter element (MG+YE), and the next equivalent picture element is wholly covered with said second filter element (CY) and half of the said next equivalent picture element is further covered with said third filter element (YE), thereby making a fourth segmented filter (G+CY), and the above filter disposition is repeated in said next horizontal line, and horizontal disposition of said one horizontal line and horizontal disposition of said next horizontal line are alternately repeated in vertical direction thereby forming two-dimensional filter mosaic pattern.

Claim 4

A solid state color imaging apparatus in accordance with claim 2, wherein said first filter element is magenta filter said second filter element is cyan filter, and said third filter element is yellow filter.

Claim 5

A solid state color imaging apparatus in accordance with claim 1, wherein in one horizontal line, a first equivalent picture element is wholly covered with a first filter element (MG) and a half of the first equivalent picture element is further covered with a second filter element (YE), thereby making a first segmented filter element (MG+R), and a next equivalent picture element is wholly covered with a third filter element (CY) and half of said next equivalent picture element is further covered with a said second equivalent picture.element (YE), thereby making a second segmented filter element (CY+G), and the,:above disposition is repeated in the horizontal line, in the next horizontal line, a first equivalent picture element which is immediately under said first equivalent picture element of said one horizontal line is wholly covered with said first filter element (MG), and half of said first equivalent picture element is further covered with a third filter element (CY), thereby forming a third segmented filter (MG+B), and the next equivalent picture element is wholly covered with said second filter element (YE) and half of the said next equivalent picture element is further covered with said third filter element (CY), thereby forming a fourth segmented filter (YE+G), and the above filter disposition is repeated in said next horizontal line, and horizontal disposition of said one horizontal line and horizontal disposition of said next horizontal line are alternately repeated in vertical direction thereby forming two-dimensional filter mosaic pattern.

Claim 6

A solid state color imaging apparatus in accordance with claim 4, wherein said first filter element is of magenta filter, said second filter element is of yellow filter, and said third filter element is of cyan filter.

Claim 7

A solid state color imaging apparatus in accordance with claim 1, wherein in one horizontal line a first picture element is wholly covered with a first filter element (YE) and a half of the picture element is further covered with a second filter element (MG), thereby making a first segmented filter element (YE+R), and a next picture element is wholly covered with a third filter element (CY) and half of said next picture element is further covered with said second picture element (MG), thereby making a second segmented filter element (B+CY), and the above disposition is repeated in the horizontal line, in the next horizontal line, a first picture element which is immediately under said first picture element of said one horizontal line is wholly covered with said second filter element (MG), and next horizontal element is wholly covered with a fourth filter element (G), and the above filter disposition is repeated in said next horizontal line, and horizontal disposition of said one horizontal line and horizontal disposition of said next horizontal line are alternately repeated in vertical directions thereby forming two-dimensional filter mosaic pattern.

Claim 8

A solid state color imaging apparatus in accordance with claim 6, wherein said first filter element is of yellow filter, said second filter element is of magenta filter, and said third filter element is of cyan filter.
