Abstract

Abstract A solid-state image pick-up apparatus comprising a colour splitting prism (2) which receives incident light images and splits them into the respective colour elements of red, blue and green light beams, a pluarality of solid-state image pick-up elements (3R, 3G, 3B) sensitive to the respective red, blue and green beams for supplying analogue signals of three primary colours, the solid-state image pick-­up elements (3R, 3B) for supplying at least red and blue analogue signals having a number of scanning lines such that higher vertical resolution can be otained than with the usual number of scanning lines used in a normal broadcasting standard, a plurality of analogue-­to-digital converters (5R, 5C, 5B) for digitising the analogue signals of the three primary colours, a registration adjustment circuit (6) to which the digital signals of the three primary colours are supplied so as to interpolate the digital signals corresponding to the red and blue beams and to add these signals to the digital signals corresponding to the green beam, a control device (10) for controlling the registration adjustment circuit (6), and a control storage device (11) for supplying data for controlling the registration adjustment circuit (6) to the control device (10).

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 199 words
A solid-state image pick-up apparatus comprising: a colour splitting prism (2) which receives incident light images and splits them into the respective colour elements of red, blue and green light beams; and a plurality of solid-state image pick-up elements (3R, 3G, 3B) sensitive to the respective red, blue and green beams for supplying analogue signals of three primary colours; characterised by: said solid-state image pick-up elements (3R, 3B) for supplying at least red and blue analogue signals having a number of scanning lines such that higher vertical resolution can be obtained than with the usual number of scanning lines used in a normal broadcasting standard; a plurality of analogue-to-digital converters (5R, 5C, 5B) for digitising the analogue signals of the three primary colours; a registration adjustment means (6) to which said digital signals of the three primary colours are supplied so as to interpolate the digital signals corresponding to the red and blue beams and to add these signals to the digital signals corresponding to the green beam; control means (10) for controlling said registration adjustment means (6); and a control storage device (11) for supplying data for controlling said registration adjustment means (6) to said control means (10).
Claim 2
Dependent Claim 199 words
A solid-state image pick-up apparatus comprising: a colour splitting prism (2) which receives incident light images and splits them into the respective colour elements of red, blue and green light beams; and a plurality of solid-state image pick-up elements (3R, 3G, 3B) sensitive to the respective red, blue and green beams for supplying analogue signals of three primary colours; characterised by: said solid-state image pick-up elements (3R, 3B) for supplying at least red and blue analogue signals having a number of scanning lines such that higher vertical resolution can be obtained than with the usual number of scanning lines used in a normal broadcasting standard; a plurality of analogue-to-digital converters (5R, 5C, 5B) for digitising the analogue signals of the three primary colours; a registration adjustment means (6) to which said digital signals of the three primary colours are supplied so as to interpolate the digital signals corresponding to the red and blue beams and to add these signals to the digital signals corresponding to the green beam; control means (10) for controlling said registration adjustment means (6); and a control storage device (11) for supplying data for controlling said registration adjustment means (6) to said control means (10).
Claim 3
Dependent Claim 38 words
Apparatus according to claim 1 wherein in said solid-state image pick-up elements (3R, 3G) supplying red and blue analogue signals, the number of vertical scanning lines is double the prescribed number of lines of the usual broadcasting standard.
Claim 4
Dependent Claim 47 words
Apparatus according to claim 2 wherein said registration adjustment means (6) comprises a plurality of circuits (6R, 6B) which interpolate the digital signals corresponding to the red and blue beams, and said plurality of circuits (6R, 6B) respectively form optimum interpolation signals from three adjacent scanning lines.
Claim 5
Dependent Claim 22 words
Apparatus according to claim 3 wherein said control storage device (11) has stored therein a ratio for composing three adjacent scanning lines.
