Claims (5)

1. En håndholdt skanner (120) omfattende en billedsensor (140); en række åbninger (135) arrangeret i et mønster med en given form, som er anbragt mellem nævnte billedsensor (140) og en scene (99); en linsedel (130), hvor linsedelen (130), billedsensoren (140) og åbningerne (135) er anbragt til at fange lys reflekteret af eller udsendt fra en stor flerhed af isolerede skelnelige punkter i scenen (99), som passerer gennem enhver af flerheden af åbninger (135) og som er modtaget af billedsensoren (140) som en flerhed af isolerede skelnelige punktbilleder, hvor ethvert af de isolerede skelnelige punktbilleder indeholder et antal billedpunkter, som er lig med antallet af åbninger (135); og en processor til at analysere ethvert billedpunkt i ethvert af de isolerede skelnelige punktbillede fra billedsensor (140) til bestemmelse af relative positioner af ethvert af de isolerede skelnelige punkt i scenen (99) i forhold til ethvert af de andre isolerede skelnelige punkter i scenen for at kortlægge et komplet tredimensionelt billede af scenen, hvor den håndholdte scanner yderligere omfatter: en lyskilde omfattende en flerhed af lyselementer (115, 116) ethvert med en farve ud af kun to farver; billedsensoren (140) med tre farvekanaler; og rækken af åbninger (135) omfattende en flerhed af åbninger (135), hvor enhver åbning er kodet til en af de to lyselementfarver for at kunne isolere de skelnelige punkter i scenen (99) på tilsvarende billedsensorfarvekanaler.
2. Håndholdt skanner (120) ifølge krav 1, hvor billedsensorens farvekanaler er røde, grønne og blå, og hvor lyselementemes farver er røde og blå.
3. En forbedret fremgangsmåde for en håndholdt skanner omfattende en billeddanner, en række åbninger og en lyskilde, hvilken fremgangsmåde omfatter at visualisere en scene ved brug af rækken af åbninger arrangeret i et mønster med en given form ved at tillade lys fra scenen kun at passere gennem flerheden af åbninger på billeddanne-ren; at sammenkoble enhver af åbningerne med en anden og adskilt del af billeddan-neren, således at lys, der passerer gennem enhver åbning, afbildes på en anden del af billeddanneren; at indfange lys reflekteret af eller udsendt fra en stor flerhed af isolerede skelnepunkter af scenen, som passerer gennem enhver af flerheden af åbninger, og som er modtaget af billeddanneren som en flerhed af isolerede skelnelige punktbilleder, hvor ethvert af de isolerede skelnelige punktbilleder indeholder et antal billedpunkter, som er lig med antallet af åbninger; og at analysere ethvert billedpunkt i ethvert af de isolerede skelnelige punktbillede fra billeddanneren til bestemmelse af relative positioner af ethvert af de isolerede skelnelige punkt i scenen i forhold til ethvert af de andre isolerede skelnelige punkter i scenen for at kortlægge et komplet tredimensionelt billede af scenen, hvori lyskilden omfatter en flerhed af lyselementer (115, 116) ethvert med en farve ud af kun to farver; billeddanneren har tre farvekana-ler; og rækken af åbninger omfatter en flerhed af åbninger, hvor enhver åbning er kodet til en af de to lyselementfarver og hvor to af tre kanaler muliggør billeddannelsen.
4. Fremgangsmåden ifølge krav 3, hvori de tre tilvejebragte kanaler er røde, grønne og blå, og hvori de to anvendte kanaler er røde og blå.
5. Fremgangsmåden ifølge krav 4, hvori enhver af flerheden af åbninger er farvekode-de som enten en rød åbning eller en blå åbning.
