Description

  The present invention relates to a camera device, an image recording method, and an image display method.

  2. Description of the Related Art Today, digital cameras that record image data of a subject imaged by an image sensor such as a CCD or CMOS sensor on a recording medium such as a memory card are widely used. The date of an image taken with a digital camera, that is, the shooting date is recorded as shooting information in an image file if the image file conforms to the standard Exif format, or is included in an arbitrary image. In general, the image is superimposed (combined) as “a part of an image” and recorded. Also, when playing back a captured image on the camera monitor, the shooting date recorded in the image file is superimposed on a predetermined portion of the display image together with other shooting information such as shooting time and image size. What can be displayed is common.

  When the captured image is played back on the camera monitor, if the shooting date is superimposed on it, simply display it, and if the shooting date is added as shooting information, As described above, it is possible to know the shooting date at the same time when the user views the image recorded on the memory card or the like by superimposing and displaying it at a predetermined location.

A technique for displaying character information superimposed on a captured image is also described in, for example, Patent Document 1 below.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a block diagram of a digital camera 1 according to the present invention common to the two embodiments. The digital camera 1 has a general function such as an AE (automatic exposure) function and has the following configuration.

  That is, the digital camera 1 includes a CPU 2 that controls the entire system, and a CCD 4 that is an imaging unit that outputs an analog imaging signal corresponding to the optical image of the subject imaged on the photosensitive portion by the optical system 3. .

  The CCD 4 is scanned and driven by a TG (Timing Generator) 5 at a predetermined cycle, photoelectrically converts the optical image of the subject, and outputs an analog imaging signal composed of pixel signals corresponding to the intensity of light to the analog processing unit 6. The CCD 4 functions as an electronic shutter by controlling the charge accumulation time according to the shutter pulse sent from the CPU 2.

  The analog processing unit 6 is a CDS (Correlated Double Sampling) that removes noise included in the imaging signal input from the CCD 4 and an AGC (gain adjustment) that is an analog amplifier that amplifies the imaging signal that has passed the CDS. Amplifier) and an AD (A / D converter) that converts an analog imaging signal amplified and adjusted by AGC into a digital signal, and outputs the imaging signal converted into digital data to the CPU 2.

  The CPU 2 has various digital signal processing functions including compression / decompression of image data. The image pickup signal output from the analog processing unit 6 is sequentially sent to the DRAM 8 via the address / data bus 7, and the image is stored in the DRAM 8. Accumulate as data. Further, after the image data stored in the DRAM 8 is read out in units of predetermined image processing blocks, digital image data for each of R, G, and B is generated, and then from the luminance (Y) component and the color difference (Cb, Cr) component. Is converted into image data (YUV data), and a video signal is generated based on the converted image data and sent to a liquid crystal monitor 9 which is an image display means of the present invention described later.

  Further, the CPU 2 compresses and encodes image data (YUV data) in units of image processing blocks by a predetermined method during image recording, and decompresses and decodes the recorded still image during reproduction. The image data compressed and encoded at the time of shooting is finally stored in the built-in flash memory 10 or the card interface (card) as an image file of the Exif standard or the like including various shooting information (file size, shooting date and time) attached thereto. The data is recorded on various memory cards 12 (recording media) that are detachable via the (I / F) 11.

  The liquid crystal monitor 9 displays a subject image updated at a predetermined frame period in the recording mode as a through image, or displays a still image read from the memory card 12 and decompressed and decoded in the reproduction mode. In addition, the liquid crystal monitor 9 displays various menu screens for assisting operations, various setting screens and messages for setting the recording image size, and shooting information and the like in the recording mode as necessary.

  The key input unit 13 is used to display the above-described various menu screens and various setting screens on the mode setting switch, shutter key, and liquid crystal monitor 9 used for setting various modes such as the recording mode and the reproduction mode. It consists of switches such as menu keys, four-way keys used for setting operations, and execution (set) switches, and sends operation signals to the CPU 2 in response to key operations by the user. The clock unit 14 counts the date and time, and sends date data and time data to the CPU 2 as necessary during shooting.

  On the other hand, in the built-in flash memory 10, a program area is secured separately from the image storage area for storing the compressed image data. The program area is necessary for various programs for causing the CPU 2 to perform various image signal processing including image data compression / decompression, color adjustment, AE (automatic exposure) control, and operations based on these programs. Various data are stored. Particularly in the present embodiment, when the recording mode is set, the CPU 2 causes the CPU 2 to perform an operation to be described later as necessary, thereby allowing the CPU 2 to execute the recording control means, the day acquisition means, the judgment means, and the image creation of the present invention. A program for functioning as a means is stored.

  In the program area of the built-in flash memory 10, in addition to the programs and data, setting data relating to various functions of the system or digital camera 1 set manually or automatically is stored in an updatable manner.

  Next, the operation of the digital camera 1 having the above configuration will be described. FIG. 2 is a flowchart showing the contents of the processing according to the present invention executed by the CPU 2 when the power is turned on. When the power is turned on, the CPU 2 first checks whether or not the travel mode is set to ON at that time (step SA1). The travel mode is a mode in which the user can set the use thereof on and off as needed, and is a mode that is intended for use during travel, for example. If the travel mode is not set on (NO in step SA1), the process proceeds to the following process.

  In other words, it is confirmed whether or not the travel mode has been set by a predetermined key operation by the user. If there is no travel mode setting operation (NO in step SA2), the power supply is turned off (NO in step SA3). Repeat judgment. In the meantime, other processing is performed. Thereafter, if the travel mode is set at any time (YES in step SA2), first, the current date held in the clock unit 14 is acquired, and the date data is set as the first day information. That is, it is stored together with other setting data in the program area of the built-in flash memory 10 (step SA4). Thereafter, image data of a bookmark image G1 (see FIG. 3) indicating the first day (first day) is created and recorded in the memory card 12 in the same manner as a normal photographed image (step SA5). The process ends.

  On the other hand, when the travel mode is already set on at the time of turning on the power (YES in step SA1), based on the current date held in the clock unit 14 and the set first day information, The current elapsed date (day n) including the first day is calculated (step SA6). Next, the presence / absence of images photographed (recorded) on each day from the second day to the (n-1) th day except the first day in the memory card 12 is confirmed (step SA7).

  Here, if there are images taken for each day (NO in step SA8), immediately create heel images G2 and G3 (see FIG. 3) indicating the current elapsed date (day n). This is recorded (step SA10), and the process is terminated. On the other hand, if there is a day with no image (YES in step SA8), for each day with no image, image data of one or a plurality of bag images indicating each elapsed date is created first, Is recorded on the memory card 12 in the same manner as a normal photographed image (step SA9), and a bag image indicating the current elapsed date (day n) is created and recorded (step SA10).

  By the above processing, for example, when the power is turned on for the first time after the second day, the heel images showing the elapsed days (the second day, the third day,...) At the time before the shooting of the day is performed. Is automatically created and recorded. For example, if the power is not turned on on the second day and the third day, and the power is turned on on the fourth day, the second day and the third day Are automatically created and recorded prior to the eyelid image indicating the fourth day. In other words, all the lapsed images are created and recorded without being lost.

  For this reason, if the user sets the travel mode on the first day of the trip, the memory card 12 includes a plurality of captured images P taken during the trip, as shown in FIG. The haze images G2 and G3 indicating the elapsed date from the first day of the day can be automatically inserted and recorded immediately before the image P taken at the beginning of each day.

  Therefore, when viewing a series of images taken by the user while traveling, for example, the series of images is displayed on the screen of the liquid crystal monitor 9 of the digital camera 1 by sequential advancement by key operation or continuously using a slide show function. When displaying the image, the user can be informed of the date on which the subsequent display image was captured by the haze images G2 and G3 displayed immediately before the shooting date of the display image is switched. That is, the user can be informed of the shooting date of each image without disturbing the viewing of the displayed image. The same effect can be obtained not only in the digital camera 1 but also in a case where a series of images are displayed by a personal computer or the like.

  In addition, since the bag image G1 indicating the first day is automatically recorded at the beginning of a series of images taken at the destination, etc., when the series of images are displayed, the first image P is taken on the first day of the destination, etc. I can tell you explicitly.

  In addition, as described above, during the travel mode setting period, all the elapsed days of 栞 images are created and recorded without being lost, so when displaying a series of images taken at a destination, etc. A sense of incongruity caused by missing images can be eliminated.

  In the present embodiment, the timing for creating and recording the above-described bag image is the time when the power is turned on for the first time on each day during the travel mode setting period. It may be the time when there was.

(Embodiment 2)
Next, a second embodiment of the present invention will be described. In the present embodiment, a program for causing the CPU 2 to perform processing to be described later is stored in the program area of the built-in flash memory 10 of the digital camera 1 shown in FIG.

  That is, FIG. 4 is a flowchart showing the contents of the processing according to the present invention executed by the CPU 2 in the power-on state. When the power is turned on, the CPU 2 checks whether or not the travel mode is set by a predetermined key operation by the user (step SB1). Also in the present embodiment, the travel mode is a mode in which the user can set the use on and off as needed, as in the first embodiment, and is intended for use during travel, for example. This mode is provided.

  If there is no travel mode setting operation (NO in step SB1), the determination of SB2 is repeated until the power is turned off (NO in step SB2). In the meantime, other processing is performed. Thereafter, when the travel mode is set at any time (YES in step SB1), the current date held in the clock unit 14 is acquired, and the date data is set as the first day information. That is, it is stored together with other setting data in the program area of the built-in flash memory 10 (step SB3), and the process is terminated. Further, the process ends when the power is turned off regardless of whether or not the travel mode is set (YES in step SB2).

  FIG. 5 is a flowchart showing the processing contents of the CPU 2 after the recording mode is set by the user in the state where the travel mode is set to ON.

  As will be described below, when in the recording mode, when there is a photographing operation by the user (step SB101), the CPU 2 performs an imaging process of a recorded image by the CCD 4, and temporarily stores the acquired imaging data in the DRAM 8 (step SB102). . Next, by confirming whether or not the image (image file) to which the current date held in the clock unit 14 is added as the photographing date exists in the memory card 12, the photographing operation confirmed in step SB101. Confirms whether or not there is a first photographing operation today, and if it is not the first photographing operation (NO in step SB103), the memory of the photographed image temporarily stored in the DRAM 8 is compressed and stored in the memory as in the normal recording mode. Recording is performed on the card 12 (step SB109).

  On the other hand, when it is the first shooting operation today (YES in step SB103), the current day's progress including the first day based on the current date held in the clock unit 14 and the set first day information. After calculating the date (day n) (step SB104), the images taken (recorded) on each day of the memory card 12 until yesterday (day 2 to day (n-1)) excluding the first day The presence or absence is confirmed (step SB105).

  If there is an image taken for each day (NO in step SB106), the image with the reduced contrast of the image is immediately updated based on the imaging data (image data) stored in the DRAM 8 immediately. Gutter images G11, G12, G13 (see FIG. 6) on which characters of the current elapsed date (day n) are superimposed are created and recorded on the memory card 12 in the same manner as a normal photographed image (step SB108). . Thereafter, the image data temporarily stored in the DRAM 8 is compressed and recorded in the memory card 12 (step SB109).

  On the other hand, if the determination result in step SB106 is YES and there is a day when there is no image, for each day when there is no image, one or a plurality of bag images G12 and G13 indicating the respective elapsed days are displayed first. After creating image data and recording it on the memory card 12 in the same way as a normal photographed image (step SB107), the above-mentioned creation and recording processing of the heel images G11, G12, G13 of the current elapsed date, A normal captured image recording process is sequentially performed (steps SB108 and SB109). Thereafter, the above process is repeated.

  Through the above processing, after the first day when the travel mode is set, each elapsed day (first day, second day, third day,...) Is superimposed on the captured image at the time when the first shooting is performed on that day. The haze images G11, G12, and G13 thus created are automatically created and recorded. For example, in the case where shooting was not performed on the second day and the third day and shooting was performed on the fourth day, the second day and the third day when the first shooting was performed on the fourth day. Two haze images consisting only of an elapse date such as a day are automatically created and recorded before a haze image in which the characters of the fourth day are superimposed on the captured image. Further, at the time of other shooting (at the second and subsequent shootings of each day), only the image shot as usual is recorded.

  Therefore, if the user sets the travel mode on the first day of travel, the memory card 12 has a plurality of captured images P captured during the travel, as shown in FIG. The haze images G11, G12, and G13 indicating the elapsed days from the first day of the day can be automatically inserted and recorded immediately before the first image taken on each day.

  Therefore, in the present embodiment as well, in the same way as in the first embodiment, when viewing a series of images taken by a user at a travel destination or the like, a bag image that is displayed immediately before the shooting date of the display image is switched. By G11, G12, and G13, the user can be instructed on what day the subsequent display images were taken. That is, the user can be informed of the shooting date of each image without disturbing the viewing of the displayed image. The same effect can be obtained not only in the digital camera 1 but also in a case where a series of images are displayed by a personal computer or the like.

  Also, when displaying a series of images, it is possible to explicitly tell that the first image P was taken on the first day of a trip or the like, and when displaying a series of images taken at a trip or the like It is possible to eliminate a sense of incongruity caused by missing oak images.

  Here, in the first and second embodiments described above, a bag image to be recorded on the memory card 12 is created at any time during the travel mode setting period. The nail image indicating the nth day) is stored in the built-in flash memory 10 or the like, and during the travel mode setting period, the nail image of the required elapsed date (nth day) is read and recorded in the memory card 12 You may make it make it.

(Embodiment 3)
Next, a third embodiment of the present invention will be described. In the present embodiment, the CPU 2 causes the program area of the built-in flash memory 10 included in the digital camera 1 shown in FIG. 1 to perform the same processing as shown in FIG. 4 and the processing described below. Thus, a program for causing the CPU 2 to function as the information addition means, information acquisition means, determination means, days acquisition means, display control means, and image processing means of the present invention is stored.

  That is, FIG. 7 is a flowchart showing the processing contents of the CPU 2 after the recording mode is set by the user in the state where the travel mode is set on.

  As will be described below, when in the recording mode, when there is a photographing operation by the user (step SC101), the CPU 2 performs an imaging process of the recorded image by the CCD 4, and temporarily stores the acquired imaging data in the DRAM 8 (step SC102). . Next, by confirming whether or not the image (image file) to which the current date held in the clock unit 14 is added as the photographing date exists in the memory card 12, the photographing operation confirmed in step SC101. Confirms whether or not there is a first shooting operation today (step SC103). If it is not the first shooting operation (NO in step SC103), the shot image data temporarily stored in the DRAM 8 is compressed in the same manner as in the normal recording mode, and the normal shooting information is added to the compressed image data. The image file is recorded on the memory card 12 (step SC106).

  On the other hand, when the shooting operation confirmed in step SC101 is the first shooting operation today (YES in step SC103), based on the current date held in the clock unit 14 and the set first day information, The current elapsed date (day n) including the first day is calculated (step SC104). Thereafter, the image data temporarily stored in the DRAM 8 is compressed, and an image file in which shooting information including the elapsed date data (hereinafter referred to as elapsed date data) is added to the memory card 12 is added to the compressed image data. Recording is performed (step SC106). Thereafter, the above process is repeated.

  FIG. 8 shows the contents of image display processing executed by the CPU 2 when displaying any image recorded on the memory card 12 in the playback mode in which the travel mode is set to ON. It is a flowchart.

  As will be described below, when displaying an arbitrary image, the CPU 2 reads an image file to be displayed from the memory card 12 (step SC201). Next, it is determined whether or not the above-mentioned elapsed date data is added to the image file, that is, whether or not the elapsed date data is included in the shooting information. If the elapsed date data is not added (step SC202). NO), the image data of the read image file is immediately decompressed, and the image is displayed on the liquid crystal monitor 9 (step SC205).

  On the other hand, when the elapsed date data is added (YES in step SC202), the habit image indicating the elapsed date (first day, second day, third day, etc.), that is, in the present embodiment, the first date In the embodiment, images similar to the haze images G1, G2, and G3 shown in FIG. 3 are created (step SC203), and the haze image is displayed on the liquid crystal monitor 9 for a predetermined time (step SC204), and then the display target image. Is displayed on the liquid crystal monitor 9 (step SC205).

  As described above, in the digital camera according to the present embodiment, the user sets a travel mode on the first day of the trip and takes a picture during the trip, and the digital camera captures a series of images taken by the user at the destination. When the travel mode is set to ON when displaying on the screen of the LCD monitor 9, the 一連 image is automatically displayed for a certain period of time immediately before the shooting date of the display image changes while displaying a series of images in order by key operation.

(Embodiment 4)
Next, a fourth embodiment of the present invention will be described. In the present embodiment, the CPU 2 performs the processes shown in FIGS. 4 and 7 in the program area of the built-in flash memory 10 of the digital camera 1 shown in FIG. 1, as in the third embodiment. A program for performing the following processing different from the third embodiment is stored.

  That is, FIG. 9 is a flowchart showing the contents of image display processing executed by the CPU 2 when displaying an arbitrary image recorded on the memory card 12 in the playback mode in which the travel mode is set to ON. It is.

  As will be described below, when displaying an arbitrary image, the CPU 2 reads an image file to be displayed from the memory card 12 (step SD201). Next, it is determined whether or not the above-mentioned elapsed date data is added to the image file, that is, whether or not the elapsed date data is included in the shooting information. If the elapsed date data is not added (step SD202). NO), the image data of the read image file is immediately decompressed and the image is displayed on the liquid crystal monitor 9 (step SD205).

  On the other hand, when the elapsed date data is added (YES in step SD202), the elapsed date (first day, second day) is added to the image with the reduced contrast of the image based on the image data of the image file to be displayed. 3) or the like, that is, images similar to the cocoon images G11, G12, and G13 shown in FIG. 6 in the second embodiment (step SD203). After displaying on the liquid crystal monitor 9 for a certain time (step SD204), the display target image is displayed on the liquid crystal monitor 9 (step SD205).

  Therefore, also in the digital camera 1 of the present embodiment, as in the third embodiment, the user sets the travel mode on the first day of the trip and takes a picture during the trip, and the user takes a picture at the destination. When displaying the series of images on the screen of the liquid crystal monitor 9 of the digital camera, if the travel mode is set to ON, the series of images are displayed in order by key operation, immediately before the shooting date of the display image is switched,栞 The image is automatically displayed for a certain time. For this reason, the user can be informed of the date on which the subsequent images were taken with the haze images (G2, G3). That is, the user can be informed of the shooting date of each image without disturbing the viewing of the displayed image.

  In the present embodiment, in the playback mode in the state where the travel mode is set to ON, the haze image displayed for a certain period of time is converted into an image in which the contrast of the image displayed thereafter is reduced (image processing is performed). An image in which characters of the elapsed date (the first day, the second day, the third day, etc.) are superimposed and created at any time, may be as follows. In other words, a bag image indicating a plurality of days of elapsed days (day n) is stored in advance in the built-in flash memory 10 or the like, and an elapsed date (n corresponding to elapsed date data added to a captured image displayed thereafter) The day image) may be read and displayed for a certain period of time.

  In addition, as in the third and fourth embodiments described above, when a bag image is created when a series of recorded images are displayed in the travel mode, for example, the following can be performed. That is, shooting mode data indicating that shooting was performed in the travel mode and first date data indicating the date of the first day of travel are added as shooting information to all the shot images recorded during shooting in the travel mode. As a playback mode, a mode is provided in which only images shot in the travel mode are played back continuously in the shooting order (recording order). And when displaying images continuously in that mode, when displaying the first image and an image whose shooting date is different from the previous display image, prior to displaying those images, Based on the first day data, the elapsed date (day n) including the first day is calculated, and the character or habit image indicating the calculated elapse date, or the eaves image in which the elapse date is superimposed on the image with reduced contrast of the image May be displayed for a certain period of time.

  Further, in the third and fourth embodiments, even if the travel mode is set during the trip, for example, shooting was performed on the third or fourth day without shooting on the second day. In some cases, when displaying a series of recorded images in the travel mode, it is not possible to display a bag image indicating the third or fourth day. To avoid this, for example, as follows: do it. That is, as in the above-described example, the travel mode at the time of playback is set to a mode in which only images captured in the travel mode are continuously played back in the shooting order (recording order). Prior to that, compare the elapsed date with the elapsed date of the 栞 image displayed for a certain period of time immediately before that to check whether there is a missing portion of the elapsed date between them. In the case where there is, there is only a need to perform processing for creating a corresponding heel image (one or more) in advance and displaying it for a certain period of time.

  Further, in the first to fourth embodiments described above, the characters included in the bag image are the dates of the schedule (the first day, the second day,...). If it has been decided, the place name of the destination can be entered, and the date and place name of the schedule can be used as the characters of the bag image. FIG. 10 shows the hail image G101, G102, G103 when it is performed in the first and third embodiments, and FIG. 11 shows the haze image G111, when it is executed in the second and fourth embodiments. It is the figure which illustrated G112 and G113, respectively.

  Further, when the travel mode is set to ON, the setting operation date is set to the first day (first day) of the trip, but it may be set to an arbitrary day. For example, when setting the travel mode, the LCD monitor 11 displays a predetermined setting screen in which the setting operation date is set as the initial value of the first day of the trip, and the user changes the initial value as appropriate on the setting screen. You may be able to do that.

  In addition, in the first and third embodiments, the haze image to be inserted and recorded between the series of captured images in the memory card 12 and the haze image created for display in the second and fourth embodiments are The image does not need to be a full-size image, and can be an image having a size smaller than the captured image.
