(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a television camera that inputs one painter.

[Conventional technology]

The conventional television image capture device that inputs the artist's information only uses a single camera to capture the image, as shown in FIG.

[Problem that the invention seeks to solve]

However, with the above-mentioned conventional technology, when the TV camera is focused on a near object, the distant object is out of focus and the 1lii image is buried, and when the TV camera is focused on the distant object, the near object Im's image is buried. has. One possibility is to increase the depth of focus of the TV camera's optical lens to increase the apparent sensitivity of a wide range, but it is difficult to cover the entire range, and the 8M signal may deteriorate due to the darkening of the image. , there are problems such as the image light receiving element not working. For this reason, when you view an image narrowed down by these methods on a display, etc., you will see a clear image if you are looking at the in-focus area, but you will have to endure the fact that the other areas will be out of focus. Ta. Even more so, when a stereo system is used to give a pseudo sense of depth, even if an attempt is made to recreate a realistic screen, the image will be blurred in the depth direction, resulting in an unsatisfactory state. Even more so, when the display capability becomes high, such as in high-definition televisions, the display becomes reborn, where the display's performance cannot be fully utilized.

[Means for solving problems]

The television imaging device of the present invention splits the incident light of an external scene, a person, etc. using a semi-transparent mirror, uses two or more television imaging cameras with different focusing, and outputs the two or more camera outputs.
The present invention is characterized in that the signal of the focal position of each pixel of number h is outputted through a circuit having means for arithmetic and selective processing.

[Implementation row]

FIG. 1 is a conceptual block diagram of the components in an embodiment of the present invention, including a semi-transparent mirror that separates incident light from the outside world, and two television cameras with different focusing positions with respect to the outside world that image the respective spectra. It consists of a circuit that inputs painter signals from the hoe material and each television imaging material in parallel, and partially selects and outputs the signal of the focused part of each corresponding scanning line, and the output signal can be used for both far and near. Although we have listed two rows of television cameras at Kashigeoka, which output clear image signals suitable for can.

Figures 2 and 3 show the different image states of the TV camera B when focusing. The scanning signal is shown in FIG.
Figure 7 shows the painter that would be reproduced if the focused and sharp peak signals of the signals in Figures 4 and 5 were partially selected and the scanning signal as shown in Figure 6 was obtained. show.

〔Effect of the invention〕

As described above, according to the invention, the light that has been separated through a semi-transparent mirror is imaged by two or more television imagers with different focusing, and the focal position of each pixel of the signal from each television camera is aligned. By outputting the signals from both sides through a circuit having a means for arithmetic and selective processing, it is possible to provide a clear image in real time as if all objects near and far were in focus.

Over time, high-definition televisions will be put into practical use, and with the development of three-dimensional televisions and large-capacity image transmission, it will be necessary to accurately convey information in the depth direction. In the past, focusing was performed solely by the will of the photographer, and this state was forced and restricted even when re-forming. However, according to the present invention, when re-forming, the scenery outside the window expands and the depth increases. This is possible by providing a screen with a realistic feel that makes you feel vividly.
