BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing device.

[0002]

2. Description of the Related Art Conventionally, many operations have been performed by buttons in an image reproducing apparatus. For example, when enlarging and scrolling an image, four buttons for up, down, left and right are required only for designating the enlarging position as shown in the remote control device of FIG. 16, and the cost is high. If you continue to hold down the buttons to scroll, rotate the image, or change the enlargement ratio, the speed of those operations does not reflect the user's intention at that time. It took too much time to do it, and there was also a situation in which scrolling, image rotation, and change in the enlargement ratio could not be stopped and could go too far. Also, if you use a mouse or a trackball, continuous movement is possible, but if you want to scroll greatly, rotate the image, or change the enlargement ratio, you have to rotate the sphere many times in one direction, The operation was troublesome.

Further, conventionally, even if the enlarged screen is scrolled, it has not been known at which position on the normal screen the enlarged screen is currently located.

Conventionally, if the image is rotated at the same enlargement ratio, the image may be cut off or a margin may be formed depending on the rotation angle of the image.

Conventionally, when an image to be displayed such as a high-definition image and the monitor have different vertical to horizontal ratios,
As shown in FIG. 7 (a), margins must be attached to the top, bottom, left, and right of the image, or the top, bottom, left, and right must be cut off as shown in FIG. 7 (b).

Further, conventionally, when displaying a plurality of images such as an index screen on one screen, it took a lot of time to perform a process for displaying the plurality of images or a search for searching for a desired image. Furthermore, when one search theme is recorded in multiple storage media as shown in FIG. 8 (a), multiple storage media must be replaced each time to display the index screen, which requires a lot of time. I was spending.

Further, conventionally, when recording an image to which a process such as enlargement has been performed on a recording medium, it has been necessary to record using one frame of image data in addition to the original image. Also, for example, if you want to compare the enlarged and scrolled screen with the normal screen, once you return to the normal screen, you can scroll the magnified screen to the same position again to get the enlarged screen at the position before the normal screen. I had to. This requires the same operation even if the change of the enlargement ratio or the processing of rotation is performed.

In the past, it was possible for a third party to easily operate a portion of an image, such as an image that is not desired to be seen by another person, that is not desired to be operated by a person other than the owner of the recording medium.

Further, conventionally, for example, when the operation part is only on the remote controller, when the power source of the remote controller is exhausted, such as exhaustion of the battery, the device cannot be operated at all.

Further, conventionally, when the cords such as the power cord and the earphone are not used, it is troublesome to worry about the storing place, and even if the storing place is built in the device, the cost becomes high and the device is large. There was a defect such as becoming

FIG. 2 shows a block diagram of the image reproducing apparatus 3. Images taken by a digital still camera are recorded on the memory card 31. Frame memory
The image data from the memory card 31 is taken into 32 by the memory control circuit 30. The memory control circuit 30 can read image data from the memory card 31, write image data to the memory card 31, write image data to the frame memory 32, and read image data from the frame memory 32. . Further, enlargement / reduction, scrolling, trimming, rotation, image processing such as displaying a plurality of images, and writing of information in the header area of the memory card 31 can be performed. The character input device 34 can send the character code and character address of the character to be displayed to the memory control circuit 30. The memory control circuit 30 can write a designated character on a screen at a designated location based on the sent character code and character address. System control circuit
33 controls the memory control circuit 30. The image is output from the memory control circuit 30 and displayed on an image display unit such as a monitor.

FIG. 3 is a conceptual diagram of the memory card 31. Various data other than image data is stored in the memory card 31. The information of the entire memory card includes the card number and the code of the card itself. Then, in the header data that is effective only for one frame of the image, the frame number, the code, whether the image is shot in the horizontal screen or the vertical screen, the aspect ratio of the image, and the character code of the search theme are written. . Further, the enlargement ratio, scroll address, trimming ratio, trimming address, rotation angle, character data, and character address can be recorded as the data of the processed image of the frame.

An example of the operation of the image reproducing device 3 is shown below. In normal reproduction, one frame of image data recorded on a recording medium such as a memory card 31 is taken into an image memory such as a frame memory 32 by the memory control circuit 30 and passed through the memory control circuit 30 again. This is done by outputting to the display unit 35.

FIGS. 4 (a) and 4 (a ') show that the image was captured in the memory card 31 in the form as shown in the figure because the digital still camera was held vertically and the image was taken. When the image is reproduced as it is, if the image output means cannot change the height and width of the screen like a TV monitor, the screen shown in FIG.
You must look at the pictures rotated 90 ° like (a) and (a ′).

FIG. 4B shows the images of FIGS. 4A and 4A 'rotated by 90 °. When shooting with the camera held vertically,
On the camera side, a switch such as a mercury switch that detects whether the camera is vertical or horizontal at the time of photographing determines whether the screen is a vertical screen and which is on the top, and writes it in the header area of the memory card 31. When the image captured on this vertical screen is reproduced on the image display unit 35, the data is shown in FIG.
The memory card 31 is loaded into the frame memory 32 once by the memory control circuit 30. At the time of output from the frame memory 32 for displaying as an image, the header information is read by the memory control circuit 30 and sent to the system control circuit 33. When the system control circuit 33 determines from the header information that the image data is vertically shot, it issues a command to the memory control circuit 30 to rotate the image 90 ° as shown in FIG. The control circuit 30 sends the image signal rotated by 90 ° to the image display unit 35.

FIG. 5A shows a desired image displayed by frame feeding. When searching for the frame before and after the normal reproduction of the image in the memory card 31 or the hard disk, the frame can be fed by turning the jog dial 21. The frame feed is performed by the following signal flow. When the system control circuit 33 of FIG. 2 determines that the jog dial 21 has been turned, the system control circuit 33 sends a command to the memory control circuit 30 to advance the frame. The memory control circuit 30 takes out the image data of the next frame being reproduced from the memory card 31, and rewrites it with the image on the frame memory 32. And frame memory 32
The image data recorded in (1) is sent to the image display section 35 by the memory control circuit 30.

FIGS. 5 (b) and 5 (b ') are obtained by changing the magnification of the image. By operating the jog dial 21 after switching to the image magnification mode by pressing the image processing button 12, it is possible to enlarge or reduce the image with the center of the screen as a reference. Thereby, the magnification of the image can be arbitrarily changed to the magnification desired by the user by the rotation angle of the jog dial 21. 5 (b) is enlarged, and FIG. 5 (b ') is reduced. Here, when the system control circuit 33 of FIG. 2 determines that the jog dial 21 has been turned after the image magnification mode is set, the jog dial 21 is turned on.
When 21 is rotated in the direction of enlargement, the enlargement image processing is performed by using the memory control circuit 30 and the frame memory 32.
This is performed by cutting out the image recorded in 1) according to the enlargement ratio and expanding the image data in the horizontal and vertical directions. If the jog dial 21 has been turned in the direction of reduction, the image data in the frame memory 32 is thinned out according to the reduction ratio and output is reduced. The image signal enlarged or reduced by the memory control circuit 30 is output to the image display unit 35. At the same time, the image magnification is set to the RAM in the system control circuit 33.
To store. The image magnification information may be recorded in the header area of the recording medium 31. However, when the image is reduced and then enlarged, the image is not degraded by enlarging the image from which data has been thinned out, and processing is performed based on the enlargement ratio and reduction ratio of the original image in the frame memory 32. Can be prevented. Further, the scaling of the image may be performed not only at the center of the screen but also at an arbitrary position as a reference.

FIG. 5 (c) shows an enlarged image, and FIG. 5 (c ') shows a screen in which the reduced image is scrolled. For image scrolling, the image processing button 12
When in scroll mode, the jog dial 21
Horizontal scroll can be performed with, and vertical scroll can be performed with shuttle link 22. Jog dial 21 in scroll mode
Alternatively, when the system control circuit 33 of FIG. 2 determines that the shuttle link 22 has been turned, the system control circuit 33 determines the position address of the upper left corner of the display image being enlarged or reduced by the memory control circuit 30. When the jog dial 21 is turned, the horizontal address is incremented, and when the shuttle link 22 is turned, the vertical address is incremented or decremented. When the address of the position to be changed is sent from the system control circuit 33 to the memory control circuit 30, the memory control circuit 30 cuts the image of the frame memory 32 from the image of the frame memory 32 according to the enlargement ratio in the case of the enlarged image, and reduces the image. In the case of, the image according to the reduction ratio is arranged at the address of the image. The scrolled image signal is output from the memory control circuit 30 to the image display unit 35. At the same time, the changed position address is stored in the RAM in the system control circuit 33 or the header area of the memory. In addition, jog dial
The speed at which 21 is turned and the speed at which the shuttle link 22 is scrolled can be changed depending on the turning angle.

FIG. 5D shows that the scrolled screen reaches the lower right end of the original image and cannot scroll further rightward or downward. The recognition that the scroll screen is at the top, bottom, left, or right of the original image,
This can be done by counting the addresses moved by scrolling. When the scroll mode is set by the image processing button 12 and the jog dial 21 or the shuttle link 22 is turned, the system control circuit 33 in FIG. 2 increments or decrements the position address. Here, in the system control circuit 33, when the address reaches a specified value indicating that it is the end of the image by scrolling, even if the jog dial 21 or the shuttle link 22 is operated, the address cannot be changed any more. ing. When the system control circuit 33 recognizes that the specified address, which is the edge of the image, has been reached, the system control circuit 33 causes the memory control circuit 30 to perform a display as shown in FIG. Send an order to. Then, the memory control circuit 30 adds a display indicating the end of the image to the scrolled screen in addition to the image signal and outputs it to the image display unit 35.

FIG. 5 (e) shows an image obtained by trimming the image at a desired angle of view and reducing it. After the image processing button 12 is pressed to enter the trimming mode, if the image magnification is reduced by the jog dial 21, the screen when the image processing button 12 is pressed is reduced and trimming can be performed. In the enlarged image, when the image processing button 12 is pressed to enter the trimming mode, at the same time, the position address of the upper left corner of the screen is recorded in the RAM in the system control circuit 33 of FIG. The recording of this position address may be performed in the header area of the memory. When the jog dial 21 is turned here, the system control circuit 33 sends to the memory control circuit 30 an instruction for trimming together with the position address and the reduction ratio. Based on the position address, the memory control circuit 30 takes out only the displayed image from the frame memory 32, reduces the image according to the reduction ratio, and outputs it as an image signal to the image display unit 35.

FIG. 5 (f) shows the image rotated by the jog dial 21 to a desired angle. The image can be rotated by pressing the image processing button 12 to enter the rotation mode and then rotating the jog dial 21. When the system control circuit 33 of FIG. 2 recognizes that the jog dial 21 has been turned in the rotation mode, the system control circuit 33 sends the rotation angle and a command for rotation to the memory control circuit 30. At the same time, the rotation angle is recorded in the RAM in the system control circuit 33. The recording of the rotation angle may be performed in the header area of the memory. When the image recorded in the frame memory is taken out by the memory control circuit 30 and the image is rotated, the rotated image is output to the image display unit 35 as an image signal.

The image processing button 1 can be used even for a normal image as shown in FIG. 6 (a).
After pressing 2 for rotation mode, you can rotate the image by rotating the jog dial 21. However,
In this case, if the image is rotated with the same image magnification, the corners of the image are cut as shown in FIG. 6 (b), so the image is reduced according to the rotation angle, and the image is reproduced as shown in FIG. 6 (c). You can also do it. When the system control circuit 33 recognizes that the jog dial 21 is turned in the rotation mode, the system control circuit 33 of FIG. 2 can also determine the reduction ratio according to the rotation angle specified by the jog dial 21 by the following formula. .

The vertical to horizontal ratio of the screen is A: B, and the rotation angle is θ.
And

[0030]

[Equation 1]

The system control circuit 33 sends to the memory control circuit 30 an instruction to perform reduction and rotation together with the determined reduction ratio and rotation angle. At the same time, the reduction ratio and the rotation angle are recorded in the RAM in the system control circuit 33. The information on the reduction rate and the rotation angle may be recorded in the header area of the memory. When the image recorded in the frame memory is taken out by the memory control circuit 30 and the image is reduced and rotated, the image is output to the image display unit 35 as an image signal.

There is also a configuration for reproducing an image as shown in FIG. 6E, which can represent an image of an outer portion of the screen, when the enlarged image as shown in FIG. 6D is rotated. This can be done by turning the jog dial 21 after setting the rotation mode by the image processing button 12 during reproduction of the enlarged image. When the system control circuit 33 of FIG. 2 recognizes that the jog dial 21 has been turned, the system control circuit 33 sends a command for performing a rotation angle and a rotation process to the memory control circuit 30 together with the enlargement ratio at this time. At the same time, the information on the rotation angle and the enlargement ratio is displayed in the system control circuit 33.
Recorded in AM. The recording of this information may be performed in the header area of the memory. The rotation processing of the enlarged image by the memory control circuit 30 does not rotate the displayed image but rotates the image after extracting the image recorded in the frame memory. It is also possible to play back the parts that have been played. The rotated image is output to the image display unit 35 as an image signal.

In FIG. 5 (g), a comment or the like is entered using the character input device 34 in the blank of the screen generated by the above operation. This makes it possible to prevent characters from overlapping the image. Of course, characters may be superimposed on the image. Display characters on the screen by the following method. The character code and the position address of the character input using the character input device 34 of FIG. 2 are converted into an actual character by the memory control circuit 30, and the character is displayed at the desired position according to the specified position address. Is overlaid with the image. The characters are displayed and the character code and position address are recorded in the RAM in the system control circuit 33. Further, the information may be recorded in the header area of the memory. The image signal superimposed on the character is sent from the memory control circuit 30 to the image display unit 35.

If the aspect ratio of the recorded image is different from the aspect ratio of the recorded image such that the aspect ratio of the recorded image is 9:16, and the screen to be displayed is 3: 4. ), The top and bottom of the screen should be blank so that the left and right sides of the image are completely within the screen, or the left and right sides of the image must be cut off and displayed as shown in FIG. 7B. Therefore, if the vertical to horizontal ratio of the captured image recorded in the header information of the memory card 31 and the vertical to horizontal ratio of the displayed screen are different,
Use the image processing button 12 to enter scroll mode, and then use the jog dial.
21 or by operating the shuttle link 22 (Fig. 7 (c))
You can also display the part outside the screen like. When the recorded image and the display screen have different vertical-to-horizontal ratios, the system control circuit 33 of FIG. 2 determines that the scroll mode has been set by the image processing button 12 and the jog dial 21 has been turned. 33 sends a command to the memory control circuit 30 to perform scrolling together with the address of the upper left corner of the image displayed by scrolling. Of the image data recorded in the frame memory, the memory control circuit 30 outputs only the image data of the address designated by the jog dial 21. At the same time, the scrolled address is recorded in the RAM in the system control circuit 33. Further, the information may be recorded in the header area of the memory. Then, the scrolled image signal is sent to the image display unit 35.

When it is desired to record the processed image being displayed on the recording medium 31 such as a memory card or a hard disk, the image processed data is not recorded on the recording medium 31, but the image processed data is recorded on the recording medium 31. . By doing so, it is possible to avoid taking a large amount of memory capacity for the image data of the processed image. When it is desired to record a processed image, the recording button 14 is pressed to write the processing information stored in the RAM in the system control circuit 33 of FIG. 2 to the header area of the frame in the memory. When the system control circuit 33 determines that the record button 14 has been pressed during reproduction of the processed image, the RAM in the system control circuit 33 for zoom ratio, scrolling, trimming position address, character code, character position address, etc.
The image processing information stored in the memory is sent to the memory control circuit 30. The processing information is stored in the header area of the recording medium 31 such as a memory card and the memory control circuit 30.
Written by When the image processing information is directly written in the header area of the recording medium 31 instead of the RAM in the system control circuit 33, the operation with the recording button 14 is not necessary. When it is desired to reproduce the processed image, by pressing the reproduction button 15 after calling the image of the frame, the target processed image can be obtained by performing each image processing based on the header information. When the reproduction button 15 is switched to the reproduction of the processed image during the normal reproduction, the system control circuit 33 issues a command to perform the image processing on the frame being reproduced on the basis of the header information. In response to this, the memory control circuit 30 performs image processing according to the header information, and the processed image is sent to the image display unit 35 as an image signal.

FIG. 8 (a) is an index screen of each memory card 31 in the search theme of Mt. Fuji, FIG.
(b) shows the index screen displaying all images of the search theme Mt. Fuji. In the index screen that displays what kind of image is in one memory card 31 or what kind of image is about a certain search theme, it takes some time until the screen is displayed. It is convenient to create an index screen for each card and search theme in advance by using one frame like). The creation can be performed by displaying the index screen for each search theme or card by the index button 16 and then pressing the record button 14 to record the index screen on the recording medium 31 such as a memory card or a hard disk. When the image of the search theme is spread over a plurality of memory cards 31 as shown in FIG. 8 (a), the cards are replaced several times and the images of the plurality of cards are stored in one screen. You can create such an index screen. When the system control circuit 33 shown in FIG. 2 recognizes that the card number or the search theme has been input by the character input device and the index button 16 has been pressed, the system control circuit 33 performs a search or the like to identify the image number to be indexed. An index processing command is sent to the memory control circuit 30. The index image is created by the memory control circuit 30 reducing and extracting an image in the recording medium 31 such as a memory card by thinning out pixels and arranging the reduced image on the frame memory 32. The display is performed by taking out the images arranged on the frame memory 32 by the memory control circuit 30 and outputting them to the image display unit 35 as image signals. The index screen is recorded by taking out the image of the index created on the frame memory 32 by the memory control circuit 30 and recording it on the recording medium 31 such as a memory card. At the same time, a recording medium such as a memory card 31
In the header part of, record the number of the card number or the index of the search theme. Also, the card number for displaying the index screen,
Alternatively, in order to input the search theme, it is preferable to record in the RAM in the system control circuit 33 or the header of the recording medium 31 that there is an index screen created in advance for the input.

FIG. 9 shows a flowchart for displaying the index screen. When the index button 16 is pressed and a card number or a search theme is input, if an index screen has been created in advance for that input, that index screen is displayed. If there is no created index screen, the necessary image data is fetched frame by frame and displayed as an index screen. Even though there is a created index screen, the recording medium such as the memory card or hard disk being accessed 31
If the image is not included in the display, that fact is displayed and awaiting replacement with another recording medium 31.

For example, even if an image is a confidential one which should not be seen by others, the image can be easily seen by anyone who can handle the image reproducing device. Therefore, it is conceivable to provide a code for each image so that the image can be viewed only by a specific person. A cipher consisting of identification of whether or not a confidential image and data of several bits is recorded in the header area of the recording medium 31 such as a memory card.

The method for creating the encrypted data using the jog dial 21 or the shuttle link 22 is as follows. The jog dial 21 and shuttle link 22 send different signals depending on whether they rotate left or right. Therefore, if you rotate the jog dial 21 or shuttle link 22 once to the right, it will be 1, and if you rotate it to the left, it will be 0.
A method of generating bit data by a signal sent from 21 or shuttle link 22 can be considered. Then, the created bit data is stored in the RAM in the system control circuit 33 one by one, and encrypted data of several bits is created.

The encryption code thus created is sent from the system control circuit 33 of FIG. 2 to the memory control circuit 30 when setting is performed, and is written in the header area of the recording medium 31 by the memory control circuit 30. Further, when the encryption is used for cancellation, the memory control circuit 30 extracts the cipher from the header area of the recording medium 31 and sends the cipher to the system control circuit 33. Therefore, the system control circuit 33 compares the cipher sent from the header area with the data input by the jog dial 21 or the shuttle link 22 to determine whether the image can be reproduced.

A method of encrypting the image itself can be considered. The image captured from the recording medium 31 to the internal memory such as the frame memory 32 is scrambled according to a certain rule, and the scrambled image is recorded again on the recording medium 31. By doing so, the image on the recording medium 31 will not be seen by another image reproducing device that does not have a decryption function. This scrambling operation may be performed at the stage of capturing an image in the card when the image is taken by the camera. The reproduction can be performed by the user inputting a signal for descrambling.

An example of setting and decoding the scramble is shown below. With the memory control circuit 30 of FIG.
When a normal image is fetched from the recording medium 31 such as a memory card to the frame memory 32, the image is scrambled to the image by the memory control circuit 30 which takes out image data consisting of several bits per pixel from the frame memory 32. The pixel data can be scrambled and recorded again on the recording medium 31. FIG. 10 shows image data of a normal image and image data after scramble processing. For scrambling, a method is considered in which the image data arranged in a fixed order such as luminance and color difference is shifted by several bits as shown in FIG. 10 so that the reproducing device side cannot read the correct data. Descrambling is performed by returning the shifted data to the original, but how many shifts are decided at the time of cipher setting, and the number of shifts can be included in the cipher. As a result, the user has to know not only the cipher recorded in the header information, but also the number of shifts for descrambling,
It has a double protection function and can prevent image dubbing.

FIG. 11 is a flow chart when the image is encrypted. It will be explained according to the flow. When playing back an image, it is first identified whether the image can be played back. If the image can be seen by anyone, it will be played back without any problem, but if it is an image for which encryption is set, press the encryption button 17 and then turn the jog dial 21 or shuttle link 22 to send several bits of data. To create. The input encrypted data is compared with the encrypted data recorded in the header area of the memory card 31, and if they match, the process proceeds to the input of the descrambling shift number. If the code is wrong, the scrambled image is played back as it is. Then similarly use the jog dial
21 or turn the shuttle link 22 to input the number of shifts for descrambling. Then, the image data is shifted and the image is output. At this time, even if the input shift number is incorrect, the shift number is shifted and the scrambled image is output. In addition, the code and the shift number are input by a series of operations that rotate the jog dial 21 or the shuttle link 22, and even if a scrambled image appears,
The user may not know whether it is due to the wrong code or the wrong shift number.

Also, by operating the image reproducing apparatus 3, the user can be restricted by setting the encryption. For example, the image erasing function can be used by anyone, and the user can confirm the code at the same time when the image erasing erasing button 13 is pressed so that the image is not erased by mistake. This operation uses the system control circuit 33 shown in FIG.
This can be done by the system control circuit 33 comparing and judging the stored cipher and the data input by the jog dial 21 and the shuttle link 22.

FIG. 12 shows an embodiment of a remote control device 10 having a power generation and storage system by rotating the jog dial 21. A generator 211 is connected to the rotary shaft of the jog dial 21, and the charger 21 is connected to the generator 211.

The storage battery 213 is charged with the electric power generated by the charger 212. Therefore, when the operation of rotating the jog dial 21 is performed, the storage battery 213 is always charged in addition to the original function of the jog dial 21. The electric power of the storage battery 213 is not supplied only from the charger 212, but may be a known storage battery that can be charged from AC100V or the like.

FIG. 13 shows an outline view of the remote control device 10 in which the jog dial 21 is provided with the winding portion of the cord 214. When cords are connected to the remote control unit, the cords can be stored by this device.
The cord 214 is connected to a microphone, an earphone, a transmitter, a receiver, and the like by a plug 214A, and exchanges signals and electric power. The range indicated by the arrow in Fig. 13 shows the operating range of the shuttle link 22, and if the shuttle link 22 is within this range, the cord take-up reel and the jog dial 21
Has a free relationship with. In FIG. 13, reference numeral 21A is provided for facilitating the operation of the jog dial 21 with a finger.

FIG. 14 shows a winding section by the jog dial 21 in the remote control device 10.
As shown in FIG. 14, when the shuttle link 22 is turned in the direction of the arrow, the jog dial portion and the reel portion are connected, and when the jog dial 21 is rotated after the connection, the cord 214 can be wound.

FIG. 15 is a sectional view of the cord winding portion 215 by the jog dial 21 in the remote control device 10. When the shuttle link 22 of FIG. 13 is turned to the set position, the shuttle contact surface 22A causes the rotating piece 217 to be the fulcrum 2.
17A is pushed down around the rotation axis, whereby the reel 216 rises and hits the connecting portion where the opposing surfaces mesh with each other. As a result, the jog dial 21 and the reel 216 are connected, and the cord 214 can be wound by rotating the jog dial 21. Signal exchange of the cord 214 wound on the reel 216 with the remote control main body may be performed by a known method such as using a brush and a rail.
