JP4090899B2 - Digital camera shooting mode setting method and digital camera - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shooting mode setting method for a digital camera and a digital camera used for carrying out this method.
[0002]
[Prior art]
When taking a picture with a camera, it is necessary to set an appropriate condition according to each shooting condition, such as night view or sports. In response to such a request, the digital camera can set various shooting modes. However, it is not easy for beginners to appropriately select and set those shooting modes. In order to facilitate this, one solution is to create various samples as a database and refer to them.
[0003]
By the way, various techniques are conventionally known as techniques for creating a database for photographing by a digital camera. For example, there are the following technologies.
[0004]
(1) When product images are converted into data and printed matter is edited, JAN codes are not handwritten, errors associated with handwriting are eliminated, and accurate processing is performed in a short time. There is a technique (for example, refer to Patent Document 1). In this technology, a subject to be photographed is photographed with a digital camera, a card that has been photographed by a computer is read with a card reader, a barcode attached to the subject to be photographed is read with a barcode reader, and the read barcode is dealt with differently. A digital image database is created by converting the file name to a digital image file name.
[0005]
(2) There is a technique for preventing forgetting to take a photograph that cannot be retaken such as a photograph of a construction site (for example, see Patent Document 2). In this technique, guide information such as a shooting location and shooting purpose is written in a memory card of a digital camera, and the guide information is displayed on a liquid crystal monitor of the digital camera at the time of shooting. The photographer takes a picture with reference to the displayed guide information. Therefore, it is possible to prevent forgetting to shoot a necessary scene. Image data acquired by shooting is stored in a memory card together with guide information corresponding to the image data, and is used for creating an album by the album editing means.
[0006]
(3) There is a technique that allows a specific scene in a moving image to be designated for printing without using an unnecessary capacity of a recording medium, and prints a still image according to the print designation (see, for example, Patent Document 3). This technology uses a digital camera for print designation to create a “print designation file” that describes a print job in a memory card that records image data, and to specify the file to be printed in this file. Information for identifying whether the print target file is a moving image file or a still image file, and information for specifying a print target scene in the moving image are recorded. The printing apparatus reads a “print designation file” from the memory card, extracts image data to be printed from the memory card based on the information, and executes printing.
[0007]
(4) In addition, there is a technique for easily performing a desired process without complicating the configuration of the image capturing apparatus (see, for example, Patent Document 4). A medium on which a bar code representing information to be input to the digital still camera, for example, information representing photographing conditions, information representing processing conditions for image processing, and the like is recorded is imaged by the digital still camera. It is determined whether the area corresponding to the barcode exists in the image, the area corresponding to the barcode is extracted, the encoded information represented by the barcode is analyzed, and the encoded information is consistent. For example, it is stored in a storage area corresponding to the type of coded information. Based on the stored information, shooting conditions are set and image processing conditions are set.
[0008]
The prior art as described above is a technique for creating a database, but it is not a technique that allows a beginner to easily set a scene-specific shooting mode of a digital camera.

[Problems to be solved by the invention]
Conventionally, when setting a scene-specific (night view, sports, macro, etc.) shooting mode on a digital camera, it is necessary to set a menu or a menu screen displayed on a switch, dial, or LCD. . The operation procedure of such a scene mode is complicated and difficult to use, and it is difficult for beginners who are users of most digital cameras.
[0011]
The present invention solves such problems, and provides a technique in which an appropriate number of scene-specific sample screens are arranged so that an appropriate scene-specific shooting mode can be automatically set. It is intended.
[0012]
[Means for Solving the Problems]
The present invention has been made in order to solve the above-mentioned problems. Preparation of shooting mode identification information is performed, and shooting means is used as a means for identifying this information, and the shooting mode is set in the camera based on the obtained information. Means for setting are provided.
[0013]
The specific technical means of the present invention is to prepare a scene-specific sample screen, shoot it with a digital camera, and automatically set the corresponding shooting mode in the camera based on the sample screen shot. And a method for setting a shooting mode of a digital camera , wherein the scene-specific sample screen is stored in a memory of the camera, and is printed out to prepare the scene-specific sample screen. .
[0014]
In the present invention, a maker prepares a manual attached with a card (one or a plurality of sheets) printed with a digital camera scene-specific sample screen (night view, sports, macro, etc.). The sample screen corresponding to the scene to be photographed is selected, and the selected sample screen is photographed with a digital camera. A camera that recognizes the sample screen has a built-in program that automatically sets the shooting mode based on this recognition, and the mode is automatically set based on the recognition.
[0015]
If marking is used together on the scene-specific sample screen, this marking can be read and mode setting can be performed, and further, if a barcode is used as this marking, the mode setting program is simplified.
[0016]
In the present invention, the scene-specific sample screens (including markings including markings) are stored in the camera memory, and are printed out to prepare the scene-specific sample screens . Can be easily played when the sample screen is soiled or lost.
[0017]
Also, in the above-described digital camera shooting mode setting method, when the scene sample screen is shot, the set mode is displayed on the liquid crystal screen, and the data of the sample screen is automatically deleted from the memory at an appropriate timing. It is preferable to provide a process to perform. This timing may be at the time of shooting, when the next sample screen is shot, or when the memory is full.
[0018]
The camera of the present invention capable of suitably carrying out the above-described method of the present invention is a digital camera that captures a scene-specific sample screen and automatically sets a corresponding shooting mode in the camera based on the sampled screen.
