Abstract

PURPOSE:To execute the search of victims based on still pictures with specifying a place and a date from navigation data by correspondingly recording a video signal and a data signal from a navigation device. CONSTITUTION:At the time of pushing a shutter or every specified period, etc., a clear pulse CP is outputted and when a specified time (a shutter time) passes, pulses Pi and Ps equivalent to one screen are outputted. The signal charge of a CCD picture pickup part 3 is transferred to a CCD storage part 4 and at the same time the signal charge of the CCD storage part 4 is transferred to a horizontal shift register 5. The transfer pulse T is outputted with synchrous to the last pulse of the transfer pulse Ps to drive the horizontal shift register 5, so that the video signal is outputted to be recorded in a recording device C. At this time, the navigation data from a navigation device 14 corresponding to the video signal is recorded in the recording device C.

Description

DETAILED DESCRIPTION OF THE INVENTION (Aspects of the Invention! 18'F) The present invention relates to a still imaging camera for aerial photography that is mounted on an airplane and takes photographs from the sky.

(Prior art and its problems) When a person is lost in a mountain, etc., conventionally, in addition to a search from the ground, an airplane is used to search for the person from the sky using binoculars.

However, when searching by airplane as mentioned above, relying on human vision makes it difficult to search a wide area, and even if there is a person in distress, it is easy to overlook it. It was easy to lose sight of someone who looked like someone, and if you lost sight of them, you would have to wait until you found them again. Furthermore, even if a person is found in distress, it is difficult to accurately confirm the location where the person was found, and the search team on the ground cannot be accurately notified, resulting in a delay in the search.

Therefore, film cameras and VTRs are used to take pictures, but since they are taken from airplanes flying at high speed, the images are blurred, making it difficult to confirm the presence of the victims. Ta.

(Object of the Invention) The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a still imaging camera for aerial photography that can be effectively used for searching for lost persons, etc. shall be.

(Structure and Effects of the Invention) In order to achieve the above object, the still imaging camera for aerial photography of the present invention includes a CCD solid-state imaging device consisting of a CCD imaging section, a CCD storage section, and a horizontal shift register, and a vertical synchronization signal. VD and in response to the vertical synchronization signal VD, the CCDt! The accumulated signal charge for one field in the image area is CC
A first transfer pulse that transfers to the D storage section, and a second transfer pulse that transfers the signal charge of the CCD storage section to the horizontal shift register.
a timing generator that outputs a transfer pulse Ps and a third transfer pulse T that extracts the signal charge of the horizontal shift register as a video signal; a video signal extracted from the horizontal/horizontal shift register and a data signal from the navigation device; and a recording device that records the information in association with each other.

According to this configuration, external light is converted into an electric signal, the signal charge is accumulated in the CCD imaging section, and the first transfer pulse P is generated from the timing generation section in response to the output of the vertical synchronization signal VD.
i and a second transfer pulse Ps, and the signal charge taken into the CCD imaging section is transferred to the CCD storage section by the first transfer pulse Pi, and the second transfer pulse Ps is output.
transfers the signal charge in the CCD storage section to the horizontal shift register, and then outputs the third transfer pulse T, thereby making it possible to take out the video signal from the horizontal shift register to obtain a still image, and to This information is recorded in a recording device along with data signals from the navigation device, and while identifying the location, date and time from the navigation data, it is possible to search for victims based on still images.

Therefore, by transferring the signal charge accumulated in the CCD m image section, it is taken out as a video signal via the CCD storage section and the horizontal shift register, and a still image is obtained based on the video signal. Therefore, by setting the transfer timing appropriately, , it is now possible to shoot with a high shutter speed, and even when shooting from an airplane, clear still images without blur can be obtained.

Moreover, it is possible to search for victims based on still images.
Accidental oversight can be avoided, and even if the victim is lost after being found, the still image of the victim can be retrieved by retrieving the video signal recorded on the recording device.
It is now possible to easily reconfirm victims.

Furthermore, since the video signal is recorded on the recording device along with the navigation data from the navigation device, by comparing the still image with the navigation data, it is possible to accurately determine the location of the person in distress, and also to find the location where the search is difficult. By extracting the video signal from the recording device and reviewing the still image at night, it is possible to reliably prevent accidental oversights, and as a whole, it is an extremely useful aerial photography method for efficiently searching for victims. We are now able to provide still imaging cameras.
