Abstract

PURPOSE:To double resolution by splitting light to two directions by a reflecting mirror etc. and make the light form images on two solid-state image pickup elements using separate lenses. CONSTITUTION:Light passed through a lens 1 forms a real image on the image forming plane F of the lens 1. A reflecting mirror or a prism 2 is placed to bring an end of its reflecting face at a position + or -delta from the position of the plane F, and the real image picture is splitted to two directions shown by arrow marks A, B. Images of light splitted to two directions are formed again on CCD image pickup elements 5, 6 by lenses 3, 4. A picture 7 is the picture image of which is formed on the element 5, and a picture 8 is the picture image of which is formed on the element 6. delta' indicates superposition of the picture 7 and picture 8, and lightness of the superposed part becomes the same lightness with other parts by composing the picture 7 and picture 8. Thus, a continuous picture having doubled resolution can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a plurality of solid-state imaging devices f (OOD!ll1t image elements). Imaging device designed to increase image resolution [[Related.

There are two ways to increase the resolution of a solid-state imaging device: (1) increasing the resolution of a solid-state imaging device, and 1-1 using multiple solid-state imaging devices and combining the captured images of each device to obtain a single image. There are two methods: *ai image t-4, equivalently increasing the resolution fft-.

This is a method of increasing the resolution of the IJJ ri element itself, and it depends on fast conductor technology. (For method II,
Conventionally, there are spatial pixel shifting method and parallel method, but spatial I
With the iR element shifting method, the resolution does not increase despite the number of elements,
There are problems in that there are gaps in the adjustment, and in the parallel system, it is difficult to provide continuity in the connection between elements.

The purpose of this IJ# is to obtain a large imaging device capable of outputting continuous images with a resolution approximately several times that of the element using an image intensifying element of 2gl.

The present invention will be explained below with reference to the drawings. In Fig. 1, light passing through the lens (11) forms a real image at the imaging plane y (the F-wire gold nail in the drawing) of the lens (1). From the position of surface F, place one end of the reflective surface of the reflecting mirror or prism (2) at the position of δ (δ: 0 and @F position), and divide the real image in two directions indicated by the arrow tAJIB). do.

For example, as an AAP image sensor, the vertical and horizontal resolutions are el(, resolution i#! of a 1aII image synthesized using two IO x 500 element tubes is 500X(1000-/
