Claims
- 1. A solid-state color imaging apparatus having color filters arrayed at a recurrence cycle of four picture elements in a vertical direction, and constructed so that in first and third rows, same-color filters for generating a same-signal component from each picture element are arrayed; in a second row, a first set of color filters for generating a first modulated color difference signal component are arrayed with a predetermined number of picture elements forming one cycle in a horizontal direction; and in a fourth row, a second set of color filters for generating a second modulated color difference signal component are arrayed with a predetermined number of picture elements forming one cycle in the horizontal direction; wherein said same-color filters of said first and third rows transmit blue, green and red light, the predetermined number of picture elements in said second row is two, and the first set of color filters comprises alternately arranged green and magenta filters.
- 2. The apparatus of claim 1, wherein the predetermined number of picture elements in said fourth row is two, and said second set of filters comprises alternately arranged first and second color filters, said first color filter transmitting red light and transmitting and attenuating incident green light so that the intensity of the transmitted green light is half the intensity of the incident green light, and said second filter transmitting blue light and transmitting and attenuating incident green light so that the intensity of the transmitted green light is half the intensity of the incident green light.
- 3. A solid-state color imaging apparatus having color filters arrayed at a recurrence cycle of four picture elements in a vertical direction, and constructed so that in first and third rows, same-color filters for generating a same-signal component from each picture element are arrayed; in a second row, a first set of color filters for generating a first color modulated color difference signal component are arrayed with a predetermined number of picture elements forming one cycle in a horizontal direction; and in a fourth row, a second set of color filters for generating a second modulated color difference signal component are arrayed with a predetermined number of picture elements forming one cycle in the horizontal direction; wherein said same-color filters of said first and third rows transmit green light and transmit and attenuate incident red and blue light so that the transmitted red and blue light is half the intensity of the incident red and blue light, respectively, thereby to approximate the spectral characteristics of the luminance signal of an NTSC color television signal.
- 4. The apparatus of claim 3, wherein the predetermined number of picture elements in said second row is two, and the first set of color filters comprises alternately arranged green and magenta filters.
- 5. The apparatus of claim 1, wherein the predetermined number of picture elements in said fourth row is two, and said second set of filters comprises alternately arranged first and second color filters, said first color filter transmitting red light and transmitting and attenuating incident green light so that the intensity of the transmitted green light is half the intensity of the incident green light, and said second filter transmitting blue light and transmitting and attenuating incident green light so that the intensity of the transmitted green light is half the intensity of the incident green light.
