Abstract

PURPOSE:To attain reproduction of focused picture by providing a focal point setting circuit changing the focal point between a storage medium and a picture forming circuit in an electronic camera system to attain the change in the focused position at reproduction. CONSTITUTION:The focal point setting circuit 18 changing the focal point is provided between the storage medium 15 and the picture forming circuit 16 and the processor is constituted so as to the focal point by processing the picture information stored in the storage medium 15. Thus, even if an object is picked up out of focus, the reproduction of the focused picture is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image processing device applied to, for example, an electronic camera system.

[Technical background of the invention]

Conventionally, electronic camera systems are shown in FIG. 1(a), for example.
(b) [Constructed as shown. (,) The figure shows the configuration of the imaging side, and in the figure, the optical system for forming a real image of the 11Fi subject 12 on the imaging surface 13a of the image sensor 13, and 14 are the drive circuits of the image sensor 13, The driving circuit 14 drives the image sensor 13 to perform photoelectric conversion. Then, the photoelectric conversion output of the image sensor 13 is transferred to a storage medium (for example, a storage element or a magnetic disk).
15 is stored.

On the other hand, Figure (b) shows the configuration on the image reproduction side, in which the electrical signals output from the storage medium 15 are processed by the image forming circuit 16 into electrical signals necessary for image formation, and are processed by the image display device, e.g. It is reproduced on the CRT display device 17.

[Problems with background technology]

By the way, in the above configuration, the focus state of the subject image is determined only on the imaging side, so naturally, if the image is captured out of focus, that is, out of focus, the reproduced image will also be out of focus. . For this reason, there is a demand for a function that allows correction (focusing) on the playback side even if the image is out of focus during image capture. Further, even if the object is in focus at a certain position, it will be out of focus at a position beyond the depth of field of the lens 11. In such cases, it would be even more convenient if the focus position could be changed on the playback side.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and its purpose is to be able to reproduce an in-focus image even if the body of a cat is taken out of focus, and to be able to maintain focus during image reproduction. An object of the present invention is to provide an image processing device that can change the position where the images match.

[Summary of the invention]

That is, in this invention, a focus position setting circuit for changing the focus position is provided between the storage medium 15 and the image forming circuit 16 in FIG. The structure is such that the pin Y position can be varied by processing.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In FIG. 2, the same components as those in FIG. 1(b) are given the same reference numerals, and their explanations will be omitted. That is, the storage medium 15 and the image forming circuit 1 in FIG. 1(b)
A focus position setting circuit 18 is provided between the pixel 6 and the pixel. Output generator 2
1, and a focus position setting signal output circuit 22 that outputs a focus position setting signal according to the user's operation. The pixel output generator 21 is comprised of an IH delay line 211 that captures and stores image information for one scanning line, a bit delay line 212 that stores image information for one bit, and the like.

The operation in the above configuration will be explained.

First, if an image is taken in an out-of-focus state, this image information is stored in the storage medium 15.

The pixel output generator 21 is supplied to the pixel output generator 21 and the pixel output generator 21 .

In the matrix circuit 19, a plurality of oscillation outputs supplied from the oscillation output 20 or 1, an output from the memory U unit 15,
Image information is corrected (focus position correction) for each pixel based on the output of the pixel output generator 2 and the output of the focus position setting signal output circuit 22. At this time,
The focus position setting signal output circuit 22 functions to change the coefficients of the calculation performed by the matrix circuit 19 in accordance with the user's skills and actions. And matrix circuit 19
The correction output output from the CR1 display device 17 is processed by the image forming circuit 16 into an electrical signal necessary for image formation, and the image of the vC wandering object 12 is reproduced and displayed.

Therefore, with such a configuration, even if the image is out of focus at the time of imaging, it is possible to correct this at the time of reproduction and reproduce an in-focus image. Also, by the same operation as above,
For example, even if an image is taken in focus at a nearby location, a reconstructed image that is focused at a different location, such as a far location, can be obtained.

In the above embodiment, the focus position setting circuit 1BVC pixel output generator 21 is provided, but if the storage medium 15 has a configuration that allows multiple readings to be performed simultaneously, the pixel output generator 21 as shown in FIG. 2 is not necessary.

〔Effect of the invention〕

As described above, according to the present invention, an excellent image processing device can be obtained which can reproduce an in-focus image even when a subject is captured in an out-of-focus state, and can also change the in-focus position during image reproduction.
