[0147]
According to the fourth embodiment, substantially the same effects as those of the above-described first to third embodiments can be obtained, and images before and after correction can be simultaneously viewed and compared.
[0148]
FIGS. 16 to 19 show a fifth embodiment of the present invention. In the fifth embodiment, the description of the same parts as those of the above-described first to fourth embodiments is omitted and mainly different. Only the points will be described.
[0149]
The external appearance of the electronic camera in the fifth embodiment is the same as that shown in FIG. 1, and the electrical configuration is the same as that shown in FIG.
[0150]
FIG. 16 is a diagram showing a logical structure of data stored in one IC card 15 as a recording unit.
[0151]
The IC card 15 is configured so that a plurality of images can be filed, and all information on each image for each image is stored in each area indicated by reference numerals a1, a2, a3, a4,. Has been recorded.
[0152]
The areas for recording information relating to one image indicated by the codes a1, a2, a3, a4,... Are roughly divided into a header section 51 for recording header information, And an image data recording unit 56 for recording the image data of the subject image that has been converted and recorded.
[0153]
The header section 51 includes a standard information header section 52 for recording standard information relating to recording of the IC card 15 as header information, and a write information header section 53 for recording other header information. The write information header section 53 further includes an area 54 for storing information on a frame number of a camera setting copy source, and an area 55 for freely recording camera setting conditions, date, and the like as header information. Is divided into two.
[0154]
In this way, the IC card 15 stores each piece of image information divided into a plurality of areas.
[0155]
Next, the operation of the fifth embodiment will be described with reference to FIG.
After photographing and recording, the mode changeover switch 23 is operated (step S151). When the camera mode is set, the camera switches to the camera mode by the sub-microcomputer 21 (step S165) and ends.
[0156]
On the other hand, when the playback mode is set in step S151, the camera is switched to the playback mode by the sub-microcomputer 21 (step S152), the image data of the frame number 1 is read from the IC card 15, and the playback image is displayed (step S153). ).
[0157]
The operator determines whether or not the reproduced image is the desired one (step S154). If the reproduced image is not the desired one, the operator operates the image selection switch 24 (step S155). The selected image data is reproduced (step S156).
[0158]
Thereafter, or if the reproduced image is a desired one in step S154, it is determined whether or not to display two screens (step S157). If not, the process is terminated.
[0159]
In step S157, when a two-screen display is performed, the two-screen operation key 30 is operated (step S158), and the IC card 15 is searched for image data having the original data of the camera setting (step S159).
[0160]
Based on the search result, it is determined whether or not the IC card 15 has the original data of the camera setting (step S160). If the original data exists, the image data and the image selected by the original data are selected. The conditions of each camera setting with the image data are displayed and reproduced (step S161).
[0161]
On the other hand, if there is no original data, the two-screen display cannot be performed, so that the two-screen display is prohibited (step S162), and a message indicating that the two-screen display is not possible is displayed (step S163).

As to the original data in step S159 in FIG. 17, it is assumed that only data relating to a newly shot image is first written in the area indicated by reference numeral a1 in FIG.
[0164]
In this case, since the image in the area denoted by reference numeral a1 is a newly photographed image, the area number information of the copy source, that is, the camera setting written in the area 55 denoted by reference numeral a1 No frame number information indicating whether the data is copied is not written.
[0165]
Next, assuming that the second image is photographed under the same conditions as the camera settings when the first image was photographed, the camera settings recorded in the area 55 indicated by the symbol a1 are copied to the area 55 indicated by the symbol a2. Written.
[0166]
At the same time, the frame number information of the copy source, that is, the frame number information relating to which frame data is copied in the camera setting written in the area 55 of the code a2 is written in the area 54 of the code a2.
[0167]
In this case, frame number information indicating that the camera setting information is copied from the area indicated by reference numeral a1 is written in the area indicated by reference numeral a2. That is, it is “1”.
[0168]
Further, when photographing the third image, for example, if it is desired to photograph under the same conditions as when the first image was photographed, the photographing is performed not by the camera setting itself of the first image but by the modified camera setting. You can also.
[0169]
Also in this case, the frame number information indicating that the camera setting information is copied from the area indicated by reference numeral a1 is written in the area indicated by reference numeral a3.
[0170]
After sequentially capturing images in this manner, for example, when trying to reproduce an image of the area a2, when the user wants to simultaneously see the original image with reference to the camera setting when capturing the image of the area a2, The original image is searched based on the frame number information written in the area 55 of the area a2 (see steps S159 and S160), and a two-screen display is performed as shown in FIG.
[0171]
That is, as shown in FIG. 18, an original image 61 reproduced from the area a1 in the IC card 15 and an image 62 reproduced from the area a2 in the IC card 15 newly photographed based on the camera settings are obtained. They are displayed side by side on two screens at the same time.
[0172]
In these images 61 and 62, camera setting conditions 63 and 64 and image frame numbers 65 and 66 are displayed, respectively.
[0173]
As described above, when certain image data and its original image data are recorded on the same IC card, two-screen display can be performed, but these are recorded on different IC cards, for example. In such a case, the two-screen display is prohibited (see step S162), a message indicating that the two-screen display cannot be performed is displayed, and the process ends (see step S163).
[0174]
In the above-described fourth embodiment, the already recorded image data and the corrected image data are displayed on two screens, whereas in the fifth embodiment, certain image data and the image data Are displayed simultaneously on two screens in order to compare a plurality of images different from the original image data with reference to the camera settings when photographing.
[0175]
In addition, although the case where the two-screen display is performed has been described above, the present invention is not limited to this. For example, as shown in FIG. 19, three screens may be displayed simultaneously.
[0176]
That is, when there are a plurality of images 71 and 72 that are newly photographed based on the image 70 serving as the reference of the camera setting conditions, these are simultaneously displayed and the respective camera setting conditions are set. Are displayed in the area 73 as indicated by reference numerals 74, 75 and 76.
[0177]
According to the fifth embodiment, substantially the same effects as those of the above-described first to fourth embodiments can be obtained, and the original data can be easily searched based on the information in the header portion.
[0178]
20 to 22 show a sixth embodiment of the present invention. In the sixth embodiment, the description of the same parts as those of the first to fifth embodiments is omitted, and the sixth embodiment is mainly different. Only the points will be described.
[0179]
The sixth embodiment is a further application of the fifth embodiment described above. The external appearance of the electronic camera is the same as that shown in FIG. 1 and the electrical configuration thereof is the same as that shown in FIG. The details of the data stored in the IC card 15 are the same as those shown in FIG.
[0180]
Next, the operation of the fourth embodiment will be described with reference to FIGS. 20 and 21 are originally one drawing, but are divided into two for convenience.
[0181]
After the photographing and recording, the mode changeover switch 23 is operated (step S171). When the camera mode is set, the process is terminated as it is. When the mode is set to the reproduction mode, a command is sent from the sub-microcomputer 21 to switch to the reproduction mode (step S171). S172).
[0182]
Next, the image data of the frame number 1 is read from the IC card 15 and reproduced (step S173), and it is determined whether or not the reproduced image is a desired image (step S174).
[0183]
If the image is not the desired image, the image selection switch 24 is operated (step S175), a desired image is selected from the IC card 15, and the image data is reproduced (step S176).
[0184]
Thereafter, or if the image is a desired image in step S174, it is determined whether or not the two-screen display is to be performed (step S177).
[0185]
If it is not necessary to display the two screens, the process ends as it is, and if it is to be displayed, the two-screen operation key 30 is operated (step S178).
[0186]
As a result, the IC card 15 refers to the header portion of the playback image selected by the image selection switch 24 in step S174, obtains the frame number information of the copy source image serving as a reference for the camera setting, and performs a search ( Step S179).
[0187]
The camera searches the IC card 15 for an image serving as a copy source (step S180). If there is no original image, it is determined that two-screen display cannot be performed, and two-screen display is prohibited (step S180). In step S181), the sub-microcomputer 21 displays that two-screen display is impossible (step S182), and ends the processing.
[0188]
On the other hand, if it is determined in step S180 that there is a copy source image in the IC card 15, the system microcomputer 16 reproduces the image selected in step S174 and the image from which the camera settings were copied in two screens. At the same time, the sub-microcomputer 21 performs setting display of each image (step S183).
[0189]
As a result, a two-screen display as shown in FIG. That is, a copy source image as indicated by reference numeral 81 and an image as indicated by reference numeral 82 newly photographed based on the camera settings of this image are simultaneously displayed side by side.
[0190]
The images indicated by reference numerals 81 and 82 display camera setting conditions 83 and 84 and image frame numbers 85 and 86, respectively.
[0191]
Next, it is determined whether or not any of the two screens displayed as described above is to be deleted (step S184).
[0192]
If there is no need for erasure, the process is terminated as it is. If erasure is required, the image selection switch 24 is operated (step S185).
[0193]
By operating the image selection switch 24, it is determined whether the image to be deleted is the image selected in step S174 or the image of the copy source searched in step S179 (step S186).
[0194]
Here, when deleting the image which is not the copy source selected in step S174, the sub-microcomputer 21 displays on the screen that the image is selected for deletion (step S187), and operates the delete key 32 (step S187). In step S188, the completion of the erasure by the sub-microcomputer 21 is displayed on the screen by an erasure display 87 of "ERASE" as shown in FIG. 22B (step S189).
[0195]
The operator enters an erasing operation for the purpose of confirmation, operates the release button 26 (step S190), and instructs the IC card 15 to delete the image data and the header part from the system microcomputer 16 (step S191). .
[0196]
The two-screen display is performed by the system microcomputer 16, but the selected and erased image data which is not the copy source is processed so as to be reproduced as a dark image in which no image is displayed. It is displayed in the state, that is, as shown in FIG. 22C, and no image is displayed in the area 88 (step S192).
[0197]
The two-screen operation key 30 is operated to return to the one-screen display (step S193), the sub-microcomputer 21 displays the frame number and the system microcomputer 16 displays a dark image (step S194), and the process ends.
[0198]
If the image to be copied is to be deleted in step S186, the sub-microcomputer 21 identifies and displays that the image to be copied is to be deleted (step S195).
[0199]
Then, it is determined whether or not the selected image that is not the copy source is moved to a blank portion when the copy source image is deleted (step S196).
[0200]
Here, when transferring a newly shot image that is not the copy source, the erase key 32 and the operation key 31 are simultaneously operated (step S197), and the sub-microcomputer 21 performs erase display (step S198).
[0201]
The release button 26 is operated to perform erasure (step S199), and the camera issues a command from the system microcomputer 16 to the IC card 15 to erase the copy source image data and header information (step S200).
[0202]
Thereafter, the system microcomputer 16 calls the selected image data and the header portion which are not the copy source (step S201), issues a command from the system microcomputer 16 to the IC card 15, and copies the called copy to the portion where the copy source image has been deleted. The non-original image data and the header part are moved (step S202).
[0203]
Then, a two-screen display is performed by the system microcomputer 16, but the image which is not the copy source selected in step S174 is displayed in the area where the image of the copy source is displayed, and the image where the image was originally displayed is displayed. Dark reproduction is performed, that is, the image is displayed as shown in FIG. 22D (step S203).
[0204]
Next, the two-screen operation key 30 is operated to return to the one-screen display (step S209), the sub-microcomputer 21 displays the number of frames, and the system microcomputer 16 reproduces the image selected and moved in step S174. (Step S210).
[0205]
On the other hand, in step S196, when the blank space after deleting the copy source image is left as it is, and the image selected in step S174 is also left there, the delete key 32 is operated (step S196). In step S204, erasure display is performed by the sub-microcomputer 21 (step S205).
[0206]
When the release button 26 is operated (step S206), a command to delete the copy source image is sent from the system microcomputer 16 to the IC card 15 and executed (step S207). The portion where the copied copy source image is displayed is darkly reproduced, that is, displayed as shown in FIG. 22E (step S208). Thereafter, steps S209 and S210 are performed, and the process ends.
[0207]
