Abstract

PROBLEM TO BE SOLVED: To obtain increased resolution by driving a lens mechanism part, to eliminate the need to provide respectively independent image pickup elements, and to make the device itself small-sized. SOLUTION: In a 1st step, image size and focus are confirmed by a lens mechanism 2 and a display means 7, input is started with a shutter release button, etc., pressed, and a control means 9 and a driving means 8 drive the lens mechanism 2 to a specific position where an image is easily photographed. In a 2nd step, the shutter function of a CCD sensor included in the lens mechanism 2 inputs an electric signal of an image and the image signal converted by a converting means 5 is stored in a storage means 5. In a 3rd step, the control means 9 and driving means 8 perform the processes of the 1st and 2nd steps similarly. Therefore, image signals of four images stored in the storage means 5 are put together by a composing means 6 in a 4th step to obtain the same image with a subject 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image input device, and more particularly, to an image input device provided with means for realizing high resolution.

[0002]

2. Description of the Related Art A conventional image input device (not shown) uses CCDs in which R, G, and B, which are three primary colors, are independent of each other in order to increase the resolution of an image in an image sensor. In order to achieve high resolution, three image sensors are required independently of each other, and the structure of the device itself becomes large,
In addition, the cost of the device itself has increased.

[0003]

Accordingly, the conventional image input device requires three image pickup devices independently of each other, so that the structure of the device itself becomes large and the cost of the device itself becomes high. Was.

Accordingly, an object of the present invention is to provide an image input device for realizing a high resolution image.

[0005]

In order to solve the above-mentioned problems, an image input apparatus according to the present invention comprises an image pickup means for picking up an image of a subject and transmitting an electric signal, and an electric signal transmitted from the image pickup means. A conversion unit for converting the image signal into an image signal; a display unit for displaying the image signal converted by the conversion unit; a lens mechanism for dividing the subject according to the resolution of the display unit to form an image; Driving means for driving; control means for controlling the imaging of the object divided by the driving of the driving means to be transmitted as the electric signal to the conversion means via the imaging means; and control means controlled by the control means. Storage means for storing image signals of each of the divided objects, and synthesizing means for synthesizing the image signals stored in the storage means so as to be displayed on the display means as the objects. And characterized in that it is configured.

[0006]

Next, an image input apparatus according to a first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an image input device according to a first embodiment of the present invention.

FIG. 2 shows display examples (A), (B) and (C) of the image input device according to the first embodiment of the present invention.

As shown in FIG. 1, an image input device according to a first embodiment of the present invention includes an image pickup means 3 for picking up an image of a subject 1 and sending out an electric signal, Converting means 4 for converting the image signal into an image signal, and display means 7 for displaying the image signal converted by the converting means 4
A lens mechanism 2 for dividing and imaging the subject 1 in accordance with the resolution of the display means 7, a driving means 8 for driving the lens mechanism 2, and a driving means 8 for driving the lens mechanism 2. A control means 9 for controlling the image formation to be transmitted as an electric signal to the conversion means 4 via the imaging means 3; a storage means 5 for storing image signals of the divided objects controlled by the control means 9; A synthesizing unit 6 for synthesizing each image signal stored in the storage unit 5 so as to be displayed on the display unit 7 as the subject 1.

Next, the operation of the image input device according to the first embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the operation of the image input apparatus according to the first embodiment of the present invention is as follows. Is divided into four parts, and the lens mechanism 2
Is a lens that matches the image size of A4 size quadrant,
In the first step, the image size and focus are confirmed by the lens mechanism 2 and the display means 7, and the shutter button or the like is pressed to start capturing. As shown in FIG. 2A, the control means 9 and the driving means 8 are operated. To drive the lens mechanism 2 to a predetermined position where an image of α can be easily photographed.

In the second step, the electric signal of the image α is captured by the shutter function of the CCD sensor included in the lens mechanism 2 as shown in FIG. Is stored in the storage means 5, and the processing of the first step and the second step is similarly performed on the images β to δ by the control means 9 and the driving means 8 in the third step.

Therefore, as shown in FIG.
In the step, the four image signals stored in the storage unit 5 are combined by the combining unit 6, and the same high-resolution image as the subject 1 is obtained.

Next, the operation of the image input device according to the second embodiment of the present invention will be described with reference to the drawings.

FIG. 3 shows display examples (A), (B) and (C) of the image input device according to the second embodiment of the present invention.

In the image input apparatus according to the second embodiment of the present invention, as shown in FIG. 3, the number of divisions is changed according to the magnification of the lens zoom as a zoom mechanism so that the resolution obtained by the lens mechanism 2 can be selected. In the case of the same size, it is possible to obtain the resolution of FIG. 3A, and in the case of four divisions, it is possible to obtain the resolution of FIG. it can.

[0017]

As described above, according to the image input apparatus of the present invention, since the lens mechanism is driven to increase the resolution, it is not necessary to provide independent image pickup devices.
In addition, there is an effect that the size of the device itself can be reduced.
