Embodiment 1

[0019] The high-resolution camera device includes a housing and a photoelectric converter capable of converting light into electrical signals in the housing. There is a light inlet hole on the housing, and the light inlet hole is only communicated with one total photoelectric converter 2, that is, all optical paths are communicated. The total photoelectric converter 2 in the light inlet is formed by merging three small photoelectric converters 1 into a concentric circular array. These three small photoelectric converters 1 are arranged on a flat circuit board to convert the small photoelectric converters respectively The incoming light on the converter 1 becomes an electrical signal, that is, a small photoelectric converter 1 only performs a photoelectric conversion function on a certain part of the total photoelectric converter 2, that is, a small photoelectric converter 1 only performs a photoelectric conversion function on a certain part of the total light inlet 1. Partial l...

Abstract

The invention relates to a high-resolution pick-up device which belongs to cameras of a photoelectric conversion pick-up camera. The high-resolution pick-up device comprises an outer housing and a photoelectric converter used for converting light into electrical signals, wherein light inlet holes are formed on the outer housing, and one light inlet hole is only communicated with one general photoelectric converter. The high-resolution pick-up device is characterized in that the general photoelectric converter in one light inlet hole is formed by combining two or more small photoelectric converters, and the two or more small photoelectric converters are combined to convert entered light into the electrical signals, namely, one small photoelectric converter only has the function of photoelectric conversion on partial light in the general photoelectric converter. The high-resolution pick-up device has the advantages that the integrated photoelectric converter of the existing camera is replaced by the general photoelectric converter formed by combining a plurality of small photoelectric converters; and under the condition of identical optoelectronic scanning frequency f, the optoelectronic scanning frequency on the unit photoelectric conversion area of the photoelectric converter can also be greatly increased, and therefore, a new way of improving the maximum image output pixel ofthe pick-up camera is found.

Description

technical field [0001] The invention belongs to the technical field of photoelectric conversion imaging, in particular to a high-resolution imaging device of a photoelectric conversion camera. Background technique [0002] Now, no matter how many camera light inlets the camera head of the photoelectric conversion camera has, one light inlet only communicates with one photoelectric converter. This photoelectric converter is a whole. If the photoelectric conversion area of ​​the photoelectric converter is A, then Under the condition of a certain photoelectric scanning frequency f, the photoelectric scanning frequency of an integral photoelectric converter is this determined photoelectric scanning frequency f, and the photoelectric scanning frequency per unit photoelectric conversion area on the photoelectric converter is the scanning precision g, g=f / a. Since the size of the photoelectric conversion area A has certain requirements, if A is too small, it will not accommodate ...
