The memory controller 7 accumulates the digital image data input from the signal processing unit 6 in the frame memory 9 and, conversely, outputs the image data in the frame memory 9 to the signal processing unit 6. The frame memory 9 is an image memory capable of accumulating image data of at least one screen.
M, SRAM, DRAM, etc. are generally used, but here, a VRAM that can operate independently of the CPU bus is used.

The image storage memory 10 is a memory built in the main body, and the image data stored in the frame memory 9 is stored after being subjected to image compression processing or the like by the main microcomputer 8. As the image storage memory 10, for example, SRAM, DRAM, EEPROM or the like is used. Considering that the image data in the memory is saved,
EEPROM is preferred. IC card controller (P
The CMCIA controller 11 connects an IC memory card (hereinafter simply referred to as an IC card) external recording medium and the main microcomputer 8, and an image stored in the frame memory 9 is compressed by the main microcomputer 8. After being processed, it can be recorded in an external storage medium via the controller 11. An external storage IC card (also referred to as a PC card) connected via the IC card controller 11 is an SRAM card, a D card, or the like.
A RAM card, an EEPROM card or the like can be used, and a modem card or an ISDN card can be used to directly transfer image data to a remote storage medium via a public line.

The strobe 12 is a circuit for causing the built-in strobe to emit light, and here the light emission timing is obtained by the main microcomputer 8 which controls the photographing sequence. The serial port driver 13 performs signal conversion for performing information transmission between the camera body and information between external devices. RS2 is used as the serial transmission means.
Although there are recommended standards such as 32C and RS422A, RS232C is used here.

The sub-microcomputer 14 controls man-machine interfaces such as operation switches of the camera body and a liquid crystal display, and transmits information to the main microcomputer 8 as necessary. Here, a serial input / output terminal is used for transmitting information to and from the main microcomputer 8. It also has a built-in clock function and controls the auto date. The diaphragm driving unit 15 is composed of, for example, an auto iris, and changes the optical diaphragm value of the diaphragm 2 under the control of the main microcomputer 8.

The focus drive section 16 is composed of, for example, a stepping motor, and changes the lens position under the control of the main microcomputer 8 to properly adjust the optical focus surface of the subject A onto the image pickup element 3. The main microcomputer 8 mainly controls a sequence of shooting, recording, and reproducing, and further performs compression / reproduction of a captured image and serial port transmission with an external device as needed. Here, J, which is standardized by CCITT and ISO for image compression, is used.
The PEG method or the JBIG method is used. A liquid crystal panel 18 is connected to the sub-microcomputer 14 and displays photographing information.

Next, a series of operations from photographing to memory recording will be described. The operation mode of the camera is set based on various switch information connected to the sub-microcomputer 14, and information for photographing is input to the main microcomputer 8 as serial information. In accordance with this information, the main microcomputer 8 sets the memory controller 7 and the serial port driver 13. When the release switch SW on the sub-microcomputer 14 is pressed, the sub-microcomputer 14 outputs the first switch signal S
1 is activated, it issues an image input command to the signal processing unit 6, and the signal processing unit 6 operates the image sensor 3, the pre-processing unit 4, and the A / D converter 5 to receive the image data. .

The signal processing unit 6 performs basic signal processing on the received image data, and then creates focus information from the high frequency component of the brightness data and exposure data from the low frequency component. The main microcomputer 8 reads these data from the signal processing unit 6 and drives the diaphragm as necessary,
Focus drive and gain control of the AGC amplifier of the preprocessing unit 4 are performed so that proper exposure and focus can be obtained. Further, depending on the operation mode, the analog image signal can be output from the signal processing unit 6 via the video amplifier 17 as an NTSC signal.

When the sub-microcomputer 14 inputs a signal indicating that the second release switch signal S2 has been pressed to the main microcomputer 8 after the exposure value and the focus have been set to appropriate values, the main microcomputer 8 A command for data acquisition is output to the memory controller 7. Also, if necessary, a light emission signal is output to the strobe 12 at the field timing of the captured image. Memory controller 7

After that, the image data is read by the signal processing unit 6 and the memory controller 7, and the analog signal of the image is output to the NTSC output terminal 19 via the signal processing unit 6. In this way, the functions of the camera for shooting, recording, reproducing, displaying and transmitting are achieved.

FIG. 30 is a diagram showing an external configuration example of a digital camera. Reference numeral 20 in the figure denotes an IC card insertion portion.
Other configurations such as the operation buttons, the display unit, and the viewfinder are the same as those of the normal camera, and thus the description thereof will be omitted.

Recently, in addition to the digital camera described above,
Each manufacturer has provided an apparatus that optically reads image information recorded on a silver salt film, converts it into digital image data, and records it on an information recording medium similar to an IC card. For example, there is a new digital photographic image processing system using an MD (mini disk) as a rewritable information recording medium. The digital photographic image processing system will be described below.

FIG. 31 is a block diagram showing an example of the arrangement of a digital image information recording apparatus. (1) ID collation mode The overall control unit 71 collates the ID of the film applied to the CCD scanner with the ID of the MD 41. In the case of film, the film ID in the case of undeveloped film
The ID is read from the reading unit 73 and given to the overall control unit 71. In the case of a developed film, the ID is directly read from the film ID reading unit 74 in the printing unit and given to the overall control unit 71. On the other hand, the ID of MD41 is
It is given from the MDID reading unit 74.

The overall control unit 71 collates the outputs of these ID reading units to check whether the IDs match. If both IDs match, the prescan mode shown below is entered. If they do not match, the film and MD do not correspond, so an alarm display is displayed on the CRT 69 to alert the operator.

In the case of MD, the barcode ID may not be attached. In this case, the CRT
The fact is displayed on 69. The operator is MD
When the image information may be written in, the pre-scan mode below is entered by instructing from the operation unit.

(2) Prescan mode A developed film (which may be negative or positive) is set in the scanner section, and image information recorded on the film is read by the CCD of the film scanner section 61. When reading with the CCD, the pixels of the CCD 61 are thinned out or integrated to reduce the number of pixels compared with the main scan. In the pre-scan, the read image data is not written in the MD but is used for determining the characteristics of the film, adjusting the color balance, index printing, etc., and the pixel density need not be so high. For example, the pixel density in the main scan is 2048 × 307 per screen.
When the number of pixels is 2 pixels, 12 per screen in prescan
Read with a density of about 8 × 192 pixels. In this way, the time required for image processing can be shortened by thinning out or integrating and reducing and reading.

The image data read by the CCD is R,
Each of G and B is converted into digital image data by an A / D converter. The converted digital image data enters the subsequent image processing unit 62, undergoes predetermined image processing, and is sequentially stored in the main memory of the memory unit 63. In the following, the overall control unit 71 uses the film 1 stored in the main memory.
The following processing is performed on the main image data.

Frame Position Discrimination At the time of pre-scanning of a film, the whole film is stored in the memory unit 63. Therefore, it is necessary to determine the frame position. The overall control unit 71 uses a predetermined determination algorithm to determine the boundaries between frames.

Panorama / 35 mm Plate Type Discrimination Next, the overall control unit 71 determines the panorama image and the normal 35 mm version.
Discrimination processing from an image is performed. The overall control unit 71 discriminates the panorama / 35 mm plane using a predetermined discrimination algorithm.

Upon completion of the processes (1) and (2), the overall control section 71 then reads out the prescan image stored in the memory section 63 and transfers it to the CRT control section 68, where C
Display on RT69. At this time, the image displayed on the CRT 69 is an image showing the division between the frames determined by the process of. The overall control unit 71 performs processing such as histogram creation for each frame, histogram creation for the entire film, representative lightness point extraction for each frame, color balance extraction for the entire film, and the like based on the processing results. RGB → YM so that an image of characteristics can be obtained
The gradation curve is written in the pre-scanning one-dimensional LUT of the C conversion unit 64.

After the gradation curve is written in the pre-scan scan one-dimensional LUT, the pre-scan image stored in the memory unit 63 is passed through this one-dimensional LUT to display the CRT.
It is stored in the video memory of the control unit 68. CR
At T69, the prescan image having the corrected characteristic is displayed. Here, the operator looks at the display image of the CRT 69 and checks whether the color, brightness, etc. are optimum. If it is not optimum, the RGB → YMC conversion unit 6
In step 4, the operator corrects the color and lightness so that the image display of the CRT 69 becomes the optimum color. This correction operation is a process of changing the curve of the one-dimensional LUT.

In the correction process described above, Y, M, and
Since the correction is based on the C characteristic, there is an effect that the operator can easily operate. When the correction processing is completed, this characteristic is fed back to the one-dimensional LUT for main scanning (built in the image processing unit 62). That is, the corrected gradation curve is written in the one-dimensional LUT for the main scan. The prescan operation is completed by the above processing.

(3) Main scan mode In the main scan, the film image is read by the film scanner section 6
This is performed using all pixels (for example, 2048 × 3072 pixels) of one CCD. R, G, photoelectrically converted by CCD
The B analog image signal is converted to R, R by the subsequent A / D converter.
Digital image data for each G and B (for example, 11 bits)
And is sent to the image processing unit 62. The one-dimensional LUT in the image processing unit 62 stores the optimum gradation conversion curve determined by the prescan. Therefore, the digital image data obtained by the main scan is subjected to optimum image conversion processing by this one-dimensional LUT. The film image data obtained by this scan is
It is temporarily stored in the memory unit 63 via the image processing unit 62.

The film image data once stored in the memory section 63 is read out frame by frame, and passes through the RGB → YMC conversion section 64 through a color correction section 65. The color correction unit 65 is a three-dimensional LU that converts the characteristics of input image data.
At T, image data not stored in the LUT is interpolated and output by a predetermined method. From this three-dimensional LUT, R, G, B image data are new R,
It is output as G and B image data. The color correction unit 65
The output of is stored in the video memory of the CRT control unit 68 via the selector 66 and displayed on the CRT 69. The operator can see the optimum image for each frame.

On the other hand, the output of the color correction unit 65 is the selector 6
The image data of the JPEG format is compressed by entering the MD processing unit 70 via 6, and the image data according to the JPEG standard is compressed. Next, the compressed image data enters the internal MD driver, and the MD drive writes the image data in the MD 41. In this way, the image data of each frame is sequentially written in the MD 41.

Thus, an apparatus for reproducing an image written on a rewritable image information recording medium (for example, MD) has been developed. This image reproducing device has, for example, an insertion slot for inserting an MD, and by inserting the MD in this insertion slot, the image information recorded in the MD can be read and displayed on the display. This device displays the displayed image
It can also be enlarged or reduced.

Next, a method of converting JPEG compressed data into data having different sampling rates will be described. Conventionally, in order to convert already completed JPEG compressed data into JPEG compressed data having different sampling rates, the compressed data is decompressed once to restore the entire image, the image is resampled, and then JPEG compressed again. The method was adopted. However, according to this method, although some of the JPEG compressed data can be used as they are without any change, if all the compressed data is expanded and recompressed, the image quality may deteriorate. Therefore, the present invention provides a method capable of suppressing image quality deterioration as much as possible when converting already completed JPEG compressed data into JPEG compressed data having different sampling rates.

In order to perform such sampling conversion, the image data writing means separates the JPEG compressed image data into a luminance signal (Y signal) and a color difference signal (C signal), and temporarily stores the separated Y signal. Means for decoding, dequantizing and inverse DCT transforming the separated C signal, and re-sampling the reconstructed image data, and DCT transforming, quantizing,
Means for performing encoding, the generated compressed data,
It is characterized in that the sampling rate of the JPEG compressed data is converted by using the means for reconstructing the temporarily stored Y signal and generating the JPEG compression data.

FIG. 3 is an explanatory diagram of the sampling method.
As shown in the figure, the sampling methods for creating JPEG compressed image data include 4: 2: 2 method and 4: 2: 2 method.
There is a 2: 0 method. There are also 4: 1: 1 methods,
Here, it is omitted. Small squares in the figure are a set of blocked pixels, for example, 8 × 8 pixels. R,
The image data read by G and B is converted into a luminance signal Y and color difference signals Cb and Cr. Y, Cb, and Cr are
It is expressed by the following equation using R, G, and B.

Y = 0.3R + 0.59G + 0.11B Cb = RY Cr = BY 4: 2: 2 Sampling method is used when it is desired to obtain high-quality compressed image data. The Y signal samples all blocks, and the Cb and Cr signals sample every other column. On the other hand, 4:
The 2: 0 sampling method is used to obtain relatively high quality compressed image data such as a picture MD. The Y signal samples all blocks and the Cb and Cr signals are
In the vertical direction, every other column is sampled, and in the horizontal direction, every other row is sampled. In either method, the luminance signal Y includes information that determines the resolution, and therefore thinning sampling is not performed. The JPEG compressed image data recorded on the MD is created by the 4: 2: 0 sampling method, while the JPEG compressed image data recorded on the IC card is 4: 2.
Consider the case of the 2: 2 sampling method.

The main microcomputer 40 reads the image data from the IC card 42 and determines the compression method of the image data. The compression method of the image data is recorded in the header portion of the image data, so that it can be easily identified. When it is determined that the 4: 2: 2 sampling method is used as a result of the determination, conversion to the 4: 2: 0 sampling method is performed.

FIG. 4 is an explanatory diagram of sampling rate conversion. (1) Operation on the digital camera side The original image data has the original image size 32 as shown in the figure.
It is assumed that the x32 pixels are compressed image data that is sampled in 4: 2: 2. The control unit of the camera body
4: 2: 2 sampling is performed from these image data. As a result, sampled image data as shown in (b) is obtained. The camera body control unit performs JPEG compression (DCT conversion → quantization →) on these image data.
Huffman coding). As a result, the completed JPEG compressed image data in the format shown in (c) is obtained. Combinations of two Y signals, one Cb signal, and one Cr signal are well arranged in sequence.

(2) Operation of the device of the present invention The main microcomputer 40 determines that the data compression method is 4: from the header of the compressed image data read from the IC card 42.
When it is determined that the 2: 2 sampling method is used, (c)
The completed compressed image data shown in (4) is separated into Y signal, Cb signal and Cr signal as shown in (d). Of these separated signals, the Y signal is temporarily stored in the RAM or the like inside the main microcomputer 40.

Then, Huffman decoding → inverse quantization → inverse DCT conversion is performed only on the Cb signal and the Cr signal to restore the original image data. As a result, image data as shown in (e) is obtained. Next, the main microcomputer 40 resamples these image data. This resampling is to sample every other row in the horizontal direction. As a result, image data as shown in (f) is obtained. JPEG compression (DC
T-transform → quantization → Huffman coding). As a result, JPEG compressed image data as shown in (g) is obtained. Next, the main microcomputer 40 reconstructs the compressed Y signal stored therein and the obtained compressed Cb signal and compressed Cr signal, and uses the 4: 2: 0 sampling method as shown in (i). Compressed image data with a different sampling rate can be obtained. The main microcomputer 40 copies (writes) the sampling rate-converted image data thus obtained into the MD 41.

FIG. 5 is a flow chart showing the sampling rate conversion operation, showing the operation of the main microcomputer 40. First, the Y signal and the C signal (C
(b, Cr signal) are separated and temporarily stored (S1). Next, Huffman coding, inverse quantization, and inverse DCT conversion are performed only on the C signal to restore the C signal (S2). Next, the restored C signal is resampled (S3). Next, DCT transform, quantization, and Huffman coding are performed on the resampled image data (S4). Then, the generated compressed C signal and the temporarily stored Y signal are reconstructed to complete the compressed image data by the 4: 2: 0 sampling method (S5).

According to this embodiment, even when the compression method of the image data recorded in the IC card is different from the compression method of the image data used in the digital photographic image processing system, the data is recorded in the IC card. It is possible to copy the recorded image information onto the information recording medium without degrading the image quality.

FIG. 6 is a flowchart showing another example of the sampling rate conversion operation, showing the operation of the main microcomputer 40. First, the Y signal and the C signal (Cb, Cr signals) of the JPEG compressed data are separated and temporarily stored (S
1). Next, Huffman coding, inverse quantization, and inverse DCT conversion are performed only on the C signal to restore the C signal (S2). next,
Color correction is performed on the restored C signal (S3). The color correction may be performed by passing the image data through a gradation conversion LUT (look-up table), for example. The main microcomputer 40 gives the restored image data to the signal processing unit 36, and the signal processing unit 36
To correct the color. The color-corrected image data is input again to the main microcomputer 40.

Thus, by performing color correction on the color difference component image data at the time of re-sampling, it is possible to obtain image data having an optimum color tone. Main microcomputer 40
Performs resampling of the color-corrected image data (S4). Next, a filtering process for obscuring the contour is performed on the resampled image data (S
5). Details of this filtering will be described later,
In the JPEG compression method, since image data is divided into blocks of 8 × 8 pixels and signal processing is performed, streaks (edges) may appear at the boundaries between blocks. Therefore, streaks at the boundaries are removed. is there.

The main microcomputer 40 performs DCT conversion, quantization, and Huffman coding on the filtered image data (S6). Then, the generated compressed C signal and the temporarily stored Y signal are reconstructed to be 4: 2: 0.
Complete the compressed image data by the sampling method (S
5).

FIG. 7 is a diagram showing a specific example of the fuzzy filter. (A) is an edge extraction filter and (b) is a smoothing filter, both of which are often used. Here, a method of obscuring edges generated between adjacent blocks will be described. FIG. 8 is a diagram illustrating the operation of the fuzzy filter. In (a), a streak (edge) 80 is generated at the boundary of each block. When the value of each pixel is calculated by applying the edge extraction filter shown in FIG. 7 to this, it becomes as shown in (b). That is, a value other than 0 (the absolute value increases as the edge becomes stronger) appears at the edge portion. Therefore, when this value exceeds a certain threshold value, it is regarded as an edge, and the smoothing shown in FIG. 7 is performed for the pixel of that portion (the pixel of the original color difference signal, not the one to which the edge extraction filter is applied) If you apply a filter,
The edges can be obscured as shown in (c). In (a), the block boundary values are "1" and "10".
However, the pixel values of adjacent blocks become closer to each other and become ambiguous.

FIG. 9 is a flow chart showing the ambiguous filter processing operation. First, the edge extraction filter is applied to one pixel (S1). It is performed by comparing whether or not the pixel after filtering is judged to be an edge with a predetermined threshold value (S2). If it is not determined to be an edge, the process skips to step S4. If it is determined to be an edge, the pixel is subjected to a smoothing filter and the calculated value is set as a new pixel value (S3). Next, it is checked whether the processing has been completed for all pixels (S4). If the process has not been completed for all pixels, the process returns to step S1 to continue the ambiguity process. When the process has been completed for all pixels, the process ends. According to this embodiment, it is possible to prevent the occurrence of streaks at the boundaries of blocks, which are the units of image processing, by performing the filter processing that makes the contours of the color difference component image data ambiguous at the time of resampling.

At the time of data transmission, image data is read from the MD drive 30 via the MD drive controller 31, and the signal modulated by the infrared data communication driver 39 is transmitted as pulsed light from the infrared data transmitter / receiver 38. When receiving data, the pulsed light received by the infrared data transmitter / receiver 38 is sent to the infrared data communication driver 39, demodulated here, and image data is written from the MD drive 30 to the MD 41 via the MD drive controller 31.

According to the first invention, the function of copying image information from the image recording IC card of the digital camera to another information recording medium and the function of copying image information from another information recording medium to the IC card. In an image recording / reproducing apparatus having at least one function of, and capable of reproducing the read image information, compression method detecting means for detecting the data compression method of the recorded image data from the information of the IC card, When the data compression method detected by the compression method detecting means is the same as the compression method of the image data to be written on the information recording medium, the image data is directly written to the information recording medium, and the detected data compression method is the information. If the compression method of the image data to be written to the recording medium is different from that of the image data, after converting the compression method of the image data, By including the image data writing means for performing the imprinting, the compression method of the image data recorded in the IC card is checked, if it is the same as the information recording medium, it is as it is, and if it is different, the compression method is used. Since the data is written in the information recording medium after the conversion of (1), the image information recorded in the IC card can be copied to another information recording medium used in the digital photographic image processing system.

In this case, the image data writing means separates the JPEG compressed image data into a luminance signal (Y signal) and a color difference signal (C signal), a means for temporarily storing the separated Y signal, and a separation means. Means for decoding, inverse quantizing, and inverse DCT transforming the C signal, and re-sampling the restored image data; and means for performing DCT transform, quantizing, and coding on the re-sampled data, By converting the sampling rate of the JPEG compressed data using the generated compressed data and the means for reconstructing the temporarily stored Y signal and generating the JPEG companded data, it is recorded in the IC card. Even if the image data compression method differs from the image data compression method used in the digital photographic image processing system and the sampling rate, The image information recorded on the C card it is possible to copy the information recording medium without deterioration of the image quality.

In the case of converting the compressed image data, color correction is performed on the restored color difference component image data before resampling, so that color correction is performed on the color difference component image data at the time of resampling. This makes it possible to obtain image data with an optimum color tone.

Further, in the case of converting the image compression data, the contour of the color difference component image data is blurred at the time of sampling by performing the filtering process for blurring the contour of the color difference component image data after resampling. By performing the filtering process of No. 3, it is possible to prevent the occurrence of streaks at the boundaries of blocks, which are the units of image processing.

Further, in the case where the device is provided with an infrared data transmission / reception unit, by providing the transmission / reception unit on a surface other than the insertion surface of the IC card or the information recording medium,
When infrared communication is used in this device, by providing the light transmitting / receiving unit on a surface other than the insertion surface of the IC card or the information recording medium, it is possible to improve the operability when the IC card or the information recording medium is taken in and out. .

It is possible to provide a good device.

Further, in the case where the device is provided with a light transmitting / receiving unit for infrared data communication, by providing a mechanism capable of connecting with a light transmitting / receiving unit of another device by an optical fiber, communication by the optical fiber can be performed. Even if a shield is placed between the two devices, the communication error is eliminated and the reliability can be improved.

Further, by providing the apparatus with a plurality of light transmitting / receiving units, by providing a plurality of light transmitting / receiving units, it is possible to connect to another device having a plurality of light transmitting / receiving units, thereby enabling multi-communication. If the amount of communication data is doubled and a certain amount of data is transmitted, the processing time can be shortened.

A second invention for solving the above-mentioned problems is a function of copying image information from an image recording IC card of a digital camera to an information recording medium and a function of copying image information from another information recording medium to an IC card. In an image recording / reproducing apparatus having at least one function of, and capable of reproducing the read image information, a management file is created from at least the file name and the shooting date / time information of the information recorded in the IC card. And a management file created by the management file creating means and a management file on the information recording medium,
Of the image information recorded on the C card, the determination means for determining whether or not the image information is already recorded on the information recording medium, and based on the determination result of the determination means, only the unrecorded image information is displayed. It is configured to include a writing unit for writing on the information recording medium, and it is determined whether or not the image is an unrecorded image by comparing the information recorded in the management file creating unit with each other by the determining unit. Therefore, only the unrecorded image information can be written in the information recording medium by the writing means.

In this case, when the image data is copied, the judging means determines that there is a file whose file names match at the copy destination, but the image data amount and the file creation date and time do not match. By changing the file name by the writing means and copying,
It is possible to copy different images with the same file name to the information recording medium by changing the file name.

When copying image data, when searching for the same image file at the copy destination,
The determination unit searches only the files in the directory designated as the copy destination, and the writing unit copies the files to limit the files to be searched to only the designated directory, thereby shortening the search time. .

Further, when copying image data, the management file creating means creates a directory corresponding to the file of the copy source in the storage means of the copy destination, and copies the directory to the directory by the writing means. File management can be efficiently performed by creating a directory corresponding to the copy source file in the copy destination storage means.

When copying image data, the management file creating means creates a directory corresponding to the creation date and time of the copy source file in the copy destination storage means, and copies it to the directory by the writing means. Thus, by creating a directory according to the creation date and time, file management can be efficiently performed.

When copying the image data, the management file creating means creates a directory corresponding to the storage means of the copy source in the storage means of the copy destination, and copies it to the directory by the writing means. By creating a directory according to the storage means of the copy source, file management can be performed efficiently.

When copying the image data, the management file creating means creates a directory corresponding to one copying operation in the storage means of the copy destination, and copies the directory to the writing means by the writing means. File management can be efficiently performed by creating a directory corresponding to one copy operation.

In the case of copying the image data, the management file creating means creates a directory corresponding to the camera that has taken the image in the storage means of the copy destination, and the writing means copies the directory to the directory, thereby taking a picture. File management can be efficiently performed by creating a directory corresponding to the camera.

Further, in the case of copying image data, the management file creating means selects a directory creation standard by making it possible to select a directory creation standard when creating a directory in the copy destination storage means.
