Description
Technical field
The invention belongs to the camera technique field of opto-electronic conversion, particularly relate to the high-resolution pick-up device of opto-electronic conversion video camera.
Background technology
No matter the camera of opto-electronic conversion video camera has several shooting light wells now, an one light well only communicates with an optical-electrical converter, this optical-electrical converter is as a whole, if the opto-electronic conversion area of this optical-electrical converter is A, under certain optoelectronic scanning frequency f condition, the optoelectronic scanning frequency of a whole optical-electrical converter is this optoelectronic scanning frequency f of determining, the optoelectronic scanning frequency of unit opto-electronic conversion area is scanning accuracy g on its optical-electrical converter, g=f/A.Because the size of opto-electronic conversion area A has certain requirement, A is too little of the light that advances in not holding with great visual angle.And the opto-electronic conversion area A of optical-electrical converter is bigger, and then scanning accuracy g is less, and scanning accuracy g is less, and just to have placed restrictions on the scope of maximum image output pixel of video camera lower.
Summary of the invention
The purpose of this invention is to provide on optical-electrical converter, the higher camera head of optoelectronic scanning frequency on the unit opto-electronic conversion area, this camera head is the part of camera.
Design of the present invention is: the image output pixel that improve video camera, the optoelectronic scanning frequency that must will make unit opto-electronic conversion area on the optical-electrical converter is that scanning accuracy improves, scanning accuracy is improved, the one, improve the optoelectronic scanning frequency f, but improve the optoelectronic scanning frequency f at present is very difficult, also is limited; The 2nd, it is long-pending to reduce on the optical-electrical converter photoelectric conversion surface, and reducing the opto-electronic conversion area is the technical essential that the present invention adopts.
Technical scheme of the present invention is:
High-resolution pick-up device, comprise the optical-electrical converter that light can be converted to the signal of telecommunication in shell and the shell, light well is arranged on the shell, a light well only communicates with a total optical-electrical converter, it is characterized in that: the total optical-electrical converter in light well is merged by two or more little optical-electrical converters and forms, two or more little optical-electrical converters merging conversions are all advanced light and are become the signal of telecommunication, and promptly a little optical-electrical converter only carries out opto-electronic conversion to certain local light of total optical-electrical converter.By this technical scheme, the opto-electronic conversion area of the total optical-electrical converter in light well is A, the opto-electronic conversion area of then little optical-electrical converter is a, must be A＞a, promptly must be the opto-electronic conversion area a of the opto-electronic conversion area A of total optical-electrical converter greater than little optical-electrical converter, under the constant condition of optoelectronic scanning frequency f, optoelectronic scanning frequency on the unit opto-electronic conversion area of little optical-electrical converter is that scanning accuracy is G, G=f/a, and the scanning accuracy in the camera head of existing camera is g, g=f/A.Because A＞a, G＞g is then necessarily arranged, (G＞g), this is with regard to the condition that provides the foundation for the video camera raising maximum image output pixel that high-resolution pick-up device of the present invention is arranged because the scanning accuracy G of the little optical-electrical converter of the present invention is necessarily greater than the scanning accuracy g that has optical-electrical converter in the camera now.Its mathematical expression that can improve maximum image output pixel effect why is:
In the camera head of existing camera, the scanning accuracy of optical-electrical converter is g, g=f/A;
The scanning accuracy of the little optical-electrical converter of each of high-resolution pick-up device of the present invention is G, G=f/a;
G=f/A, G=f/a, because A＞a, so G＞g, the scanning accuracy of little optical-electrical converter is better than the scanning accuracy of optical-electrical converter in the camera head of existing camera.
The output signal of telecommunication of the whole little optical-electrical converters in the same total optical-electrical converter of the present invention is merged through the multiple signals combiner, become the total output signal of telecommunication that comprises that the whole light of this light well convert to, be used for carrying out imaging with other parts of video camera.Other parts that should total output signal of telecommunication connect video camera just can obtain the maximum image output pixel also higher than existing maximum image output pixel under the constant condition of optoelectronic scanning frequency f.Like this, under the constant condition of optoelectronic scanning frequency f, the present invention has found the new way that improves video camera maximum image output pixel, has just found by graduation optical-electrical converter area in kind, remerges the high-resolution pick-up device that multiple signals can improve scanning accuracy.
The output signal of telecommunication of the whole little optical-electrical converters in same total optical-electrical converter, become a signal of telecommunication output through the merging of multiple signals combiner, can be used as the photosignal that improves video camera maximum image output pixel.
Total optical-electrical converter can become plane or level and smooth curved surface, and a plurality of little optical-electrical converter on same total optical-electrical converter becomes parallel array or annular array, can also be the face array of other form.
Optical-electrical converter of the present invention is the device that can convert light to the signal of telecommunication, and optical-electrical converter can be selected CMOS optical-electrical converter or CCD optical-electrical converter for use.
Advantage of the present invention: improve the maximum image output pixel of video camera, the scanning accuracy that improves camera head in the camera is important method and primary condition.Improve the scanning accuracy of camera head in the camera, the most important thing is to improve the optoelectronic scanning frequency on optical-electrical converter unit's opto-electronic conversion area, promptly increase more optoelectronic information on the unit opto-electronic conversion area.Be exactly the present invention the former as a whole optical-electrical converter of camera head in the existing camera, total change into the synthetic optical-electrical converter of a plurality of little optical-electrical converter of the present invention, replaces an existing whole optical-electrical converter with total optical-electrical converter.Like this, under identical optoelectronic scanning frequency f condition, the area of little optical-electrical converter is less than existing whole optical-electrical converter area, just can significantly improve the optoelectronic scanning frequency on the unit opto-electronic conversion area of optical-electrical converter, promptly significantly improve scanning accuracy, found the new way that improves video camera maximum image output pixel, new parts.
