Abstract

PURPOSE:To obtain a panoramic picture with only one pickup by recording an object picture data and attribute information of an anamorphic lens to a removable storage means in pairs and decoding the compressed picture into an original picture at reproduction based on the attribute information of the anamorphic lens. CONSTITUTION:A CPU 6 has information relating to a characteristic of an anamorphic lens 1 in advance and records the characteristic of the anamorphic lens 1 to an attribute recording part 11 and a video signal to a video data part 12 in a memory card 7 through a memory controller 5. Moreover, the CPU 18 reads the information of the attribute recording part 11 of the memory card 7 by loading the memory card 7 and designating a picture number through the operation of a keyboard 21 to control a signal processing circuit 15 in response to the information and reads the picture data thereby decoding the compressed picture by a signal processing circuit 15. Thus, a panoramic picture is picked up by one pickup and a panoramic picture or a scroll picture is displayed by the mode selection at reproduction.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a digital electronic still camera system that uses an anamorphic lens to obtain panoramic images.

``Prior art'' Conventionally, in order to obtain a horizontally elongated screen (hereinafter referred to as a panoramic screen) using normal screen processing in a silver halide film camera, the subject was compressed horizontally and placed on the film surface through an anamorphic lens. When recording, developing and projecting, the original image is again projected through another anamorphic lens to obtain the original panoramic screen; A method has also been proposed in which a panoramic image is obtained using a camera.The camera is rotated at one time to take a plurality of images, and the images are combined to obtain a panoramic image (for example, Japanese Patent Laid-Open No. 1-251962).

``Problem to be solved by the invention'' In the case of silver halide film, especially for movies, the anamorphic lens is used again during playback, making the entire system complex and expensive, and the anamorphic lens is used both during shooting and playback. The problem is that the image quality is poor because it uses a lens, and there is also a lack of immediacy. Next, in the case of an electronic still camera, although it is instantaneous, it is necessary to rotate and position the camera, which makes the device large and complicated, making it expensive. There was a problem that it was necessary.

The present invention aims to obtain a panoramic image using a simple device, which is instantaneous and requires only one photographing.

[Invention or means to solve the problem]

The present invention provides a digital electronic camera to which an anamorphic lens can be attached, in which compressed f-trinuclear image data to be processed on the anamorphic lens and attribute information of the anamorphic lens are attached and detached as a pair. A digital electronic camera that is capable of recording (-1) compressed images based on the attribute information of the anamorphic lens and restoring them to the original image during playback, and is equipped with screen display method selection means during playback. provide the system.

[For production]

If the configuration of the present invention is applied, a panoramic image can be obtained instantly with one shooting.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a basic configuration diagram of a digital electronic camera intended for photographing. A subject image is formed on a solid-state image sensor 3 through a detachable anamorphic 1/lens 1 and an imaging lens 2. The video signal output from the solid-state image sensor 3 is A/D
After being converted, it is processed into a predetermined recording format for the signal processing circuit 4. When the anamorphic l/lens 1 is installed, the detection signal from the detection means 8I is sent to the CPU 6.
The CPU 6 contains information regarding the characteristics of the anamorphic lens in advance.

As shown in FIG. 2, the CPU records the characteristics of the anamorphic lens in the attribute recording section 11 and the video signal in the video data section 12 in each area of the memory card 7 through the memory controller 5.

The above explanation focused on the method using the detection means 8, but in a camera with a built-in anamorphic 1/lens, if you change the mode to panorama mode, the lens will switch to the anamorphic lens and the signal processing will also change to panorama mode. It may be configured to switch.

If the anamorphic lens itself stores lens information in advance and has one built-in IC, when an anamorphic lens is attached, the lens information will be changed to CptJ.
The data may be recorded on the memory card 7 via 6V.

Figure 3 shows one memory card 7 which is a basic configuration diagram of the playback machine.
When the user attaches the camera and designates an image shop by operating the keyboard 21, the CPU 18 reads information from the attribute recording section 11 of the memory card 7 and controls the signal processing circuit 15 in accordance with the information. The image data is read out, the signal processing circuit 15 restores the compressed image, and the restored data is recorded in the frame memory 16. TV monitor 20V
c To display the image, the CPU 18 commands the memory controller 17 to transfer the image from the frame memory 16.
The signal is output to the television monitor 20 through the A converter.

Next, FIG. 4 shows an original panoramic image of the subject.

Images taken with a digital electronic still camera equipped with the anamorphic 1/lens explained in Figure 1 are compressed into a single image as shown in Figure 5 using the compression ratio determined by the lens. . The image data on the memory card is this compressed image data.

FIG. 6 shows an example of a panoramic image displayed on the TV monitor 20 after the image has been restored as described above.

Since a horizontally long screen is displayed on a monitor, the top and bottom are cut off to create a panoramic image. Figure 7 shows that when the scroll mode is selected on the keyboard 21 during playback, the TV monitor 20
It is also possible to scroll and view the range from the left end to the right end of the panoramic original image in FIG. 4.

〔Effect of the invention〕

Normally, it is possible to take standard pictures as an electronic still camera, but by attaching an anamorphic lens, a panoramic image can be taken in one shot. Also, during playback, mode selection vC = repanoramic image or scroll image is displayed, allowing different types of panoramas to be provided.

[Brief explanation of the drawing]

FIG. 1 is a schematic configuration diagram of an electronic camera according to an embodiment of the present invention, FIG. 2 is an explanatory diagram showing a data area of a semiconductor memory card, and FIG. 3 is a schematic configuration diagram of a playback device according to the embodiment. FIGS. 4 to 7 are explanatory diagrams showing the relationship between a subject image and a reproduced image.
