× 480 dots) is a liquid crystal display device.

A shutter SW 114 is a switch for instructing the start of a photographing operation. This shutter SW11
Reference numeral 4 denotes a switch position in two stages depending on the pressing pressure of the switch. When the position of the first stage (low pressing pressure—hereinafter referred to as “half pressing position”) is detected, the locking operation of camera settings such as white balance and AE is performed. Then, upon detecting the position of the second stage (strong pressing pressure—hereinafter referred to as “shutter ON position”), a capture signal capturing operation is performed.

Hereinafter, the processing procedure of the camera operation in this embodiment will be described with reference to the flowcharts shown in FIGS. 2, 3, 4, and 5.

FIG. 2 is a flowchart showing the flow of the viewfinder function in the camera photographing operation mode.

In step 201, when the power is turned on or the switch is switched to the photographing operation mode, first, in step 202, the CCD module including the CCD 106 and the CCD control unit 107 can be operated (e).
Next, in step 203, the operation of the display unit 113, which is an electronic viewfinder for confirming the subject at the time of shooting, is started.

Next, from step 204 onward, a continuous process until an image captured from the camera module is displayed on the display unit 113 will be described. In step 204,
A process of converting light information of a subject taken from the camera lens group 105 into an electric signal by the CCD 106 is performed.

Processing such as automatic white balance, AE, correction at the time of flash photography, or signal conversion to a YUV (4: 2: 2) format is performed. Step 207
In the present embodiment, the photographing mode is determined because the photographing mode 2 in which the captured image is subjected to the binarized image processing and displayed only in the region designated by the operator is displayed. In the case of the photographing mode 1 in which no image processing is performed, in step 209, the YUV-converted signal is directly used by the CPU.
101, a VRAM 10 for storing display image data
3c, use LCD and DMA transfer
Output to the control unit 111. In the case of the imaging mode 2, in step 208, binarization processing is performed on the image in the area specified by the operator of the display unit 113. In step 208, the YUV received from the image processing unit 108
For the data of (4: 2: 2), the CPU 101 first refers to the work area 103b of the RAM 103 with the coordinates of the diagonal of the rectangular area specified by the means described later, and determines the data of the target area. Execute the binarization process. The binarization process is performed on YUV (4: 2: 2) data Cb1, Y1, Cr1, Y2, Cb3, Y3, Cr3,
Y4,... (Y: luminance signal, Cb and Cr: color difference signal) The color difference signal is fixed to an appropriate value, and the magnitude of the luminance signal Y is compared with a set threshold value S. If it is larger than S, it is converted to the maximum value, and if smaller than S, it is converted to the minimum value. The image data including the binarized data is written by the CPU 101 into the VRAM 103c storing the display image data (step 2).
09), after converting the YUV signal received by the LCD control unit 111 into an RGB digital signal in step 210, outputs an RGB signal to the display drive unit 112 in step 211. This display drive unit 112
In step 212, the display unit 113 displays an image of a subject in response to the output signal from.

As described above, steps 204 to 212
By continuously looping the processing up to the cycle of 1/30 second, the subject image is constantly monitored on the display unit 113. By the way, if the operation of the switch by the photographer is detected during the loop monitoring this video,
An interrupt event is generated by the detection signal, and the process shifts to an interrupt process A.

FIG. 3 is a flowchart showing a control procedure of an interruption process by a key operation during a camera photographing operation.

At the stage when this switch operation occurs, there is internally one of two modes. One is a normal mode, in which the viewfinder operation described with reference to FIG. 2 is continuously performed after the power is turned on. The other is a half-press mode, in which the viewfinder operation is performed in a state where the shutter is once pressed halfway and various camera settings are locked. In the figure, the start position of the process is described separately in two cases, that is, the process from the normal mode and the process from the half-press mode.

Step 301 is a SW status reading process for checking which switch operation has been performed in the interrupt process from the normal mode. If the shutter ON position (strong pressing pressure) is detected in step 302, in step 303 various types of control performed in the image processing unit 108, such as auto white balance, AE, and flash correction in flash shooting. The camera settings are locked with the current set values, and subsequently, in step 316, the operations of the display drive unit 112 and the display unit 113 are stopped in order to reduce the processing load of the CPU 101. Next, in step 317, in the case of the photographing mode 1, a capture signal is captured, and after predetermined processing in the image processing unit 108, the data of the YUV signal is written to the image development area 103a in the RAM 103. In the case of the photographing mode 2, after performing binarization processing (similar to the processing in step 208) on a designated area for the captured image, the image data is stored in the RAM 103.
Write to the image development area 103a inside. This data is subjected to image compression processing conforming to the JPEG standard in step 318, and then, in step 319, the compressed data is stored in the data storage unit 104 (flash memory).
Write as an image file to Then, step 32
0, the display driving operation that has been stopped is restarted. In step 321, image data is displayed on the display unit 113 for a certain period of time so that the captured image can be confirmed. In step 322, the interrupt processing is terminated. Then, the process returns to the loop of FIG. 2 and the viewfinder process is restarted.

Next, when the half-press position (weak press pressure) is detected from the SW status reading in step 301 (step 304), first in step 305, the internal state setting is set to the half-press mode. In step 306, as in step 303, various camera settings in the image processor, such as auto white balance, AE, and flash correction in the case of flash shooting, are locked with the current settings. Thereafter, in step 307, the interrupt processing ends, and the process returns to the loop of FIG.

Further, the step 308 is executed based on the SW status.
In step 309, when it is detected that the switch for changing the photographing condition is pressed, in step 309, the image processing unit 108 controls the auto white balance, the AE, and the flash correction in the case of flash shooting. After the various camera settings are corrected in accordance with the condition change, the flow proceeds to the return processing of step 307.

If it is detected in step 310 that the OFFSW has been pressed, the operation of the display drive is terminated first (step 311), and then the operation of the CCD module is terminated (step 312). After performing the other photographing operation end processing, the system power-off processing is executed. If no OFF key is detected in step 310, it means that a valid key or switch operation has not been detected.
The processing proceeds to the return processing of step 307 without performing any processing.

Next, the flow of interrupt processing in the half-press mode will be described. Step 314 is a SW status reading process for checking which switch operation has been pressed in the interrupt process from the half-press mode. Here, when the shutter ON position is detected in step 315, the various camera settings (step 306) in the image processor locked by the previous detection of the half-press key (step 304) are enabled, and step 316 is performed. The process proceeds to the execution of the subsequent photographing process (described above). If the SW status detects half-press release as shown in step 323, the internal state setting is released from the half-press mode in step 324, and the process proceeds to the return process of step 322. If half-press release is not detected in step 323, it means that a valid key or switch operation has not been detected, and the process proceeds to the return process of step 322 without performing any processing.

FIG. 4 is an interrupt processing flowchart showing a flow of a process of specifying an area when an input of a handwritten tablet installed on the display unit 113 is detected during a photographing operation (viewfinder function). This embodiment will be described with reference to an external perspective view of the display unit of the camera of this embodiment.

In the schematic view of the display unit shown in FIG. 6, the display unit (LC
D) The handwriting tablet 110 is installed above the 113, and the position specified by the operator with the touch pen 604 with respect to the image displayed on the display unit 113 is detected by the output of the handwriting tablet. The image display area of the display unit 113 is in the range of 601. The icon display unit 602 displays an icon for instructing to turn off the power or cancel the operation, and is instructed when an input is detected. Performs processing corresponding to the icon.

In the flowchart of FIG. 4, when an input of the handwriting tablet 110 is detected, step 401 is performed.
Then, the designated coordinates are determined, and if it is the image display area 601 of the display unit 113, the process proceeds to step 402 to determine the current shooting mode, and in the case of the shooting mode 1, it is displayed on the display unit 113. It is determined that the operator has started the operation of designating the area to be binarized for the selected image, and step 4
At 03, the specified range is detected. In the designation of the area, the output from the handwriting tablet 110 is used as the coordinates corresponding to the display unit 113 through the tablet control unit 109 as C.
Since the PU 101 is notified, as shown in FIG. 6, the operator uses the touch pen 604 to move the coordinates 605 on the display unit 113.
By tracing from a to 605b, it is possible to specify a quadrangular area 603 having a diagonal end point 605b where the touch pen 604 is separated from the start point 605a. When the area designation is started, the currently designated area is always displayed by a dotted line 603 in order to clearly indicate the range designated by the operator. When the touch pen 604 is released from the handwriting tablet, the process proceeds to step 404, where the area indicated by the dotted line 603 is determined as a binarization target area, and the coordinates of the start point 605a and the end point 605b of the specified area are stored in the work area of the RAM 103. The coordinates are stored in the area 103b, and the coordinates are referred to in step 208 in FIG. In step 405, since the area to be binarized is set, the shooting mode is set to 2
Is set in step 412 and the process returns to step 204 of the main routine.

If the photographing mode is 2 in step 402, the operator designates 2 for the already designated area.
Since the operation of changing the parameter of the value conversion or the change of the designated area is instructed, the process proceeds to step 406, and it is determined whether the detected position on the handwritten tablet is within the frame of the dotted line 603 or on the dotted line 603, If it is within the frame of the dotted line 603, the setting of the binarization parameter is changed in step 407. In the setting change, a process of increasing or decreasing the value of the threshold value S is performed. If the position on the handwritten tablet detected in step 406 is on the dotted line 603, a change in the designated area is detected in step 408, and step 409 is performed.
The coordinates of the starting point and the ending point of the diagonal of the area designated by are stored in the work area 103b in the same manner as the processing of step 404, and the processing is returned. If it is out of the frame of the dotted line 603 in step 406, nothing is performed and the process returns in step 412.

In step 401, the icon display unit 602
If the area is designated, a process corresponding to the displayed icon is performed in step 411. At this time, if cancel is selected in the icon display of the icon display area 602, it is determined in step 410 that the end of the binarization processing has been instructed, and the shooting mode is returned to 1. At this time, the display unit 113 returns to a state where the binarized area is not specified.

FIG. 5 is a view for reproducing and displaying a photographed image.
6 is a flowchart illustrating a flow of a process in a reproduction operation mode.

In step 501, when the power is turned on or the switch is switched to the reproduction operation mode, first, in step 502, the operation of the display unit 113, which is an electronic viewfinder for confirming a subject at the time of photographing, is started. Next, in step 503, the compressed image data file written in step 319 in FIG. 3 (photographing operation) is read from the data storage unit 104 (flash memory), and written in the image development area 103a in the RAM 103. An image decompression process, that is, a process of converting compressed data conforming to the JPEG standard into original data (YUV data) is executed, and in step 505, the decompressed original data is written to the VRAM 103c for storing display image data. Or later,
First, in step 506, as in the processing of steps 210 to 212 in FIG.
After the signal is converted into an RGB digital signal, an RGB signal is output to the display drive unit 112 in step 507. In response to the output signal from the display driving unit 112, in step 508, the display unit 113 displays a subject image.

As described above, in the digital camera of this embodiment, the result of performing the image processing specified for the area specified by the operator is displayed on the display unit during the shooting operation (viewfinder function). This allows the operator to take a picture while always checking the result of imaging while taking the picture, so that a failure at the time of taking a picture is reduced and an easy-to-use camera can be provided.

When characters are included in the photographed image, the characters can be easily read by binarization, and the entire image can be photographed as a natural image.

In this embodiment, binarization processing is performed on a specified area of the display unit as image processing. However, image processing such as brightness change or mosaic processing may be performed. Good.

(Second Embodiment) In the first embodiment, an image obtained by performing binarization processing on an area designated during the operation of the finder function is displayed on the display unit 113. In the second embodiment, as an image processing method, enlargement processing is performed on a designated area, and the result is displayed in another designated area on the display unit. The image after the enlarging process is superimposed and displayed on a partial area of the photographed image. The hardware configuration in this embodiment is the same as that in the first embodiment.

In the present embodiment, the operation in step 208 is changed from the operation in FIG. 2 of the first embodiment. The processing procedure of step 208 in this embodiment will be described with reference to the flowchart of FIG. 7 and the display example of this embodiment in FIG. If the photographing mode is 2 in step 207, step 2
08, that is, the process proceeds to step 701 in FIG. 7, and temporarily stores the image signal data in the image development area 103a of the RAM 103.
1 is enlarged, and the image after the enlargement processing is overwritten on the area of the image data temporarily stored in the image development area 103a corresponding to the designated enlarged image display area 902 (step 703). At this time, the area 90 in the image
Numerals 1 and 902 are designated by rectangular areas, and information of diagonal coordinates (FIG. 9: a and b of 901 and A and B of 902) are stored in the work area 103b according to a processing procedure of FIG. Therefore, enlargement processing is executed with reference to this value. The enlargement ratio in the enlargement process is defined in both the X and Y directions by the ratio of the rectangular areas 901 and 902. In step 704, after transferring the enlarged YUV image data to the VRAM 103c,
The process proceeds to step S10, where the image subjected to the enlargement processing is displayed on the display unit 113 by the processing of steps 210 to 212.

Next, rectangular areas 901 and 90 by the operator
The processing procedure of 2 designation detection will be described with reference to the flowchart of FIG.

When the input of the handwriting tablet 110 is detected, the designated range is determined in step 801, and if it is the image display area, the current shooting mode is determined in step 802, and the shooting mode is determined. In the case of 1, since the operator has started the operation of specifying the area to be enlarged with respect to the image displayed on the display unit 113, the specified range is detected in step 803. To specify the area to be enlarged, the output from the handwriting tablet 110 is output to the tablet control unit 10.

01, the operator uses the touch pen 604 to
By tracing from the coordinates 901a to 901b on the display unit 113, the rectangular area 901 can be designated by detecting the diagonal coordinates of the end point 901b at which the touch pen 604 is separated from the start point 901a. When the operation of specifying the area to be enlarged is started by the operator, the currently specified range is always indicated by a dotted line 901 to clearly indicate the specified range.
To display. Touch pen 604 is handwritten tablet 11
When it is separated from 0, the area currently indicated by the dotted line 901 is determined as the target area of the enlargement processing in step 804, the coordinates of the start point 901a and the end point 901b are stored in the work area 103b of the RAM 103, and the above-described step of FIG. 7

03 in the work area 103b. Step 80
In step 6, the photographing mode is set to 2, and the process returns to the main routine in step 810. If the photographing mode is 2 in step 802, an instruction to change the area to be enlarged or the enlarged image display area is given to the already specified area. It is determined whether the upper position is the area to be enlarged or the enlarged image display area. If the area is the area to be enlarged, the process proceeds to step 808. When the touched pen is released after moving the frame line, the diagonal coordinates of the rectangular area changed to reset the enlarged area are stored in the work area 10 of the RAM 103.

Are stored in the work area 103b of the RAM 103, and the process returns to step 811.

If it is determined in step 807 that the enlarged image display area has been designated, in step 809, the change of the enlarged image display area is performed on the frame line if the touch pen is moved in the same manner as in the processing of step 808 if the touched pen is moved. When the touch pen is released and the touch pen is released, the diagonal coordinates of the rectangular area changed to reset the enlarged image display area are stored in the RAM.
103 is stored in the work area 103b. If the size of the rectangular area is changed within the enlarged image display area, the rectangular area is moved and the touch pen is released while the size of the rectangular area is changed with the movement of the touch pen.
