Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup system, and more particularly to a technique effective when applied to an image pickup system for picking up a moving image with high resolution.

[0002]

2. Description of the Related Art A conventional image pickup system basically comprises a lens system 1, a photoelectric conversion system 2 and a signal processing system 3 as shown in FIG.

The lens system 1 is composed of an optical lens for forming an optical image of a subject on an image pickup device (image pickup means) (not shown) of the photoelectric conversion system 2.

The photoelectric conversion system 2 is, for example, a well-known CCD.
It is composed of an image sensor such as (Charge Coupled Device) and a drive circuit for driving the image sensor, and converts an optical image of a subject formed on the image sensor into an electric signal.

The signal processing system 3 performs amplification of electric signals and various corrections.

In such a conventional image pickup system, the resolution of the picked-up image, that is, the resolution of the picked-up image is mainly determined by the number of light receiving elements of the image pickup element (not shown) of the photoelectric conversion system 2.

FIG. 7 is a diagram showing a schematic structure of an image pickup element, and 2p shows a light receiving element.

In FIG. 7, the two-dimensionally arranged light receiving elements 2p are particularly suitable for capturing a moving image.
The two-dimensional light and dark distribution of the optical image formed on p is converted into the magnitude of the electric signal.

When one frame image is picked up, photoelectric conversion is simultaneously performed by all of the light receiving elements 2p, but when the photoelectric conversion result is taken out as one electric signal, a method known as scanning, that is, each is used. Light receiving element 2p
Are read in time series.

In recent years, the above-mentioned image pickup device is formed on one semiconductor chip and is called a solid-state image pickup device.

That is, since the resolution of the picked-up image is determined by the number of light receiving elements 2p formed on the semiconductor chip, the higher the number of light receiving elements, the higher the resolution of the image that can be picked up.

Therefore, in the conventional image pickup system, the number of light receiving elements 2p per unit area is increased by forming the light receiving elements 2p at a high density by a fine processing technique or the like, or the size of the semiconductor chip is increased. Light receiving element 2 formed on one image pickup element by increasing the area
High-definition of a captured image has been performed by using a method of increasing the number of p.

A cell including one light receiving element on a semiconductor chip is called a pixel of an image pickup device.

[0014]

SUMMARY OF THE INVENTION As a result of studying the above prior art, the present inventor has found the following problems.

In the conventional image pickup system, in order to increase the resolution of a picked-up image, it is necessary to keep increasing the number of light receiving elements 2p on the image pickup element. However, when the number of light receiving elements 2p is increased, the image pickup element is scanned. There was a problem that the clock frequency for doing so must be increased.

The above-mentioned clock frequency is proportional to the number N of light receiving elements from which information is read out per unit time, where n is the number of light receiving elements on the image pickup element and f is the number of frames (frame frequency) per unit time. , N is as shown in the following equation.

[0017]

## EQU1 ## N = n × f On the other hand, when capturing a moving image, f needs to have a certain value or more. For example, the current system televisions such as NTSC system TV and HDTV (High
In Density Television, it is 30 frames / second.

Therefore, in order to increase the resolution of the picked-up image by increasing the number of light receiving elements of the image pickup element used in the NTSC system TV, it is necessary to increase the clock frequency in proportion to the number of light receiving elements.

In the conventional image pickup device, a moving image can be picked up (frame frequency is 30 frames / sec or more), and the image pickup device having the largest number of light receiving elements 2p is H.
2 million pixels (1000 x 2) used for DTV
It is an image sensor of about 000 pixels).

As the image pickup device having the number of pixels of 2 million pixels or more, the "Proceeding of SPIE Vo

5000 × described in "D Image Sensor and Camera"
There are 5000 CCD type image pickup devices, but both have a problem that the frame frequency is as low as 10 or less and cannot be applied to moving image pickup.

An object of the present invention is to provide a technique capable of outputting an image picked up by a conventional high-resolution image pickup means at a high frame frequency.

The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[0023]

It is as follows.

In an image pickup system having an image pickup means for picking up an image of a subject and a conversion means for converting the image pickup into an electric signal, and outputting the electric signal as an image signal, the image pickup means has a predetermined number of images. The first image pickup means and the second image pickup means having the number of pixels larger than the predetermined number of pixels are photographed in the same area as the first image pickup means, and the first image pickup means picks up the image. Motion vector generation means for detecting a motion area and a motion vector of the motion area from an image;
An image generating unit that generates a new image from the image captured by the second image capturing unit based on the moving region and the motion vector, and outputs the new image together with the image captured by the second image capturing unit. And.

According to the above-mentioned means, the image picked up by the second image pickup means which cannot be driven at the frame frequency necessary for picking up the moving picture is picked up by the first image pickup means in order to output at the frame frequency for picking up the moving picture. From the image, the vector generation means detects the moving area in the image and the motion vector thereof.

On the other hand, the image generating means outputs the high-quality image captured by the second image capturing means in synchronization with the output cycle determined by the frame frequency of the moving image capturing, and based on the moving area and the motion vector. , An image to be dropped is newly generated from an image having a large number of pixels captured by the second image pickup means, that is, a high quality image, and at a timing at which the newly generated image is dropped, By outputting as an image captured by the second image capturing unit, a high-quality image captured by the second image capturing unit having a large number of pixels can be output at each output cycle determined by the frame frequency of moving image capturing. It is possible to output a high-quality image captured by the second image capturing unit having high resolution at a high frame frequency.

In the first embodiment, the lens 1, the super-multipixel image pickup device 21, and the low pixel image pickup device 2 are used.
Needless to say, the light 2 and the half mirror 4 are housed in a case (not shown), and only the light that has passed through the lens 1 is incident on the super-multipixel image pickup device 21 and the low-pixel image pickup device 22.

FIG. 2 is a diagram for explaining the operation of generating an image between frames. (I) ... (i + 4) (where i is a natural number of 1 or more) is a frame number, Rm is a moving area, and Rs is Is a still region, Vm is a motion vector when the moving region Rm moves from frame (i) to frame (i + 1), T is a frame period of the low pixel imaging device 22, and particularly in the first embodiment.

Therefore, the frame period of the super multi-pixel image pickup device 21 is 2T.

Next, the operation of the image pickup system according to the first embodiment will be described with reference to FIG. 2. First, the light incident from the lens 1 is transmitted by the half mirror 4 to the super multi-pixel image pickup device 21.
