BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment in which the present invention is applied to a digital still camera (hereinafter, abbreviated as “digital camera”) will be described with reference to the drawings.
[0036]
FIG. 1 shows the circuit configuration, and reference numeral 10 denotes a digital camera. The digital camera 10 can be set by switching between a photographing mode and a reproduction mode as a basic mode. In a monitoring state in the photographing mode, a lens optical system in which a focus position and an aperture position are moved by driving a motor 11. A CCD 13, which is an image pickup device disposed behind the 12 photographing optical axes, is scanned and driven by a timing generator (TG) 14 and a vertical driver 15, and outputs one photoelectric conversion output corresponding to an optical image formed at regular intervals. Output for the screen.
[0037]
This photoelectric conversion output is appropriately adjusted in gain for each of the RGB primary color components in the state of an analog value signal, sampled and held by a sample and hold (S / H) circuit 16, and digitally converted by an A / D converter 17. And output to the color process circuit 18.
[0038]
The color process circuit 18 performs a color process process including a pixel interpolation process and a γ correction process on the digital data of the image sent from the A / D converter 17, and outputs a digital luminance signal Y and color difference signals Cb, Cr. Is generated and output to a DMA (Direct Memory Access) controller 19.
[0039]
The DMA controller 19 converts the luminance signal Y and the color difference signals Cb and Cr output from the color process circuit 18 into the DMA controller 21 once using the composite synchronization signal, the memory write enable signal, and the clock signal from the color process circuit 18 as well. And a DMA transfer output to a DRAM 21 used as a buffer memory via a DRAM interface 20.
[0040]
After the DMA transfer of the luminance and chrominance signals to the DRAM 21 is completed, the control unit 22 reads the luminance and chrominance signals from the DRAM 21 via the DRAM interface 20 and writes the signals into the VRAM 24 via the VRAM controller 23.
[0041]
The digital video encoder 25 periodically reads the luminance and color difference signals from the VRAM 24 via the VRAM controller 23, generates a video signal based on the data, and outputs the video signal to the display unit 26.
[0042]
The display unit 26 includes, for example, a color liquid crystal display panel with a backlight and a driving circuit for the display unit. The display unit 26 is disposed on the rear side of the digital camera 10 and functions as a monitor display unit (electronic finder) in a shooting mode. By performing the display based on the video signal from the digital video encoder 25, an image based on the image information fetched from the VRAM controller 23 at that time is displayed.
[0043]
When the image at that time is displayed on the display unit 26 in real time as a monitor image in this way, when the shutter key among the plurality of keys constituting the key input unit 27 is operated at the timing when the user wants to take a still image, And generate a trigger signal.
[0044]
The control unit 22 stops the path from the CCD 13 to the DRAM 21 immediately after the completion of the DMA transfer of the luminance and color difference signals for one screen taken from the CCD 13 to the DRAM 21 at that time in response to the trigger signal, Transit to the record save state.
[0045]
In this recording and storage state, the control unit 22 transmits the luminance and chrominance signals for one frame written in the DRAM 21 via the DRAM interface 20 to each of the Y, Cb, and Cr components by 8 pixels by 8 pixels. Is read out in units called basic blocks, and written into a JPEG (Joint Photography Coding Experts Group) circuit 28, which is an ADCC (Adaptive Discrete Cosine Transform) and an entropy coding system. Data compression by processing such as conversion.
[0046]
Then, the obtained code data is read out from the JPEG circuit 28 as a data file of one image, and written on a memory card 29 which is detachably mounted as a recording medium of the digital camera 10 and which contains a flash memory as a nonvolatile memory. Put in.
[0047]
Then, with the compression processing of the luminance and chrominance signals for one frame and the completion of writing of all the compressed data to the memory card 29, the control unit 22 activates the path from the CCD 13 to the DRAM 21 again.
[0048]
The control unit 22 is further connected with a GPS receiver 30, a direction sensor 31, an angle sensor 32, a distance measurement sensor 33, and an altitude sensor 34.
The GPS receiver 30 calculates three-dimensional coordinate data of the current position, that is, data of latitude, longitude, and altitude, and current time based on radio waves arriving from a plurality of GPS satellites received by the GPS antenna 35, and performs the above control. To the unit 22.
[0049]
The azimuth sensor 31 includes a magnetic sensor for detecting terrestrial magnetism and a processing circuit thereof, and outputs azimuth data in a direction directly facing the camera body of the digital camera 10 to the control unit 22.
[0050]
The angle sensor 32 includes a gyro sensor and a processing circuit, and outputs angle data of an elevation angle or a depression angle formed by a photographing optical axis constituted by the lens optical system 12 and a horizontal plane to the control unit 22.
[0051]
When the digital camera 10 has an active AF (automatic focusing) function, the distance measuring sensor 33 emits infrared rays to the subject position and receives the reflected light thereof. The processing circuit calculates the distance to the subject from the time lag from light transmission to light reception, and outputs the obtained distance data to the control unit 22.
[0052]
The altitude sensor 34 includes an atmospheric pressure sensor and a processing circuit, and calculates altitude data of the current position according to a change in the atmospheric pressure from the set altitude position, and outputs the altitude data to the control unit 22.
[0053]
The key input unit 27 includes, in addition to the shutter key described above, a mode switching key for switching between a photographing (REC) mode and a playback (PLAY) mode, which are basic modes, a “menu” key for displaying various menu items, A cross key to indicate the up, down, left, and right directions for selecting images and various detailed modes, specifying menu selection items, etc.It is arranged at the center of this cross key and indicates the contents selected at that time And a display key for turning on / off the display on the display unit 28. Signals associated with these key operations are sent directly to the control unit 22.
[0054]
Next, the operation of the above embodiment will be described.
The shutter key of the key input unit 27 operates in two stages of strokes, and performs AF (automatic focusing) and AE (automatic exposure) in a first stage operation state generally expressed as "half-press". It is assumed that the preparation for the first shooting is performed, and the shooting is executed in the operation state of the second stage in which the pressing operation is performed more strongly, which is generally expressed as “fully pressed”.
[0055]
FIGS. 2 and 3 mainly show the processing contents executed by the control unit 22 in a state where the photographing mode is selected as the basic mode.
At the beginning of the processing, the image captured by the CCD 13 is held as it is in the DRAM 21 serving as a buffer memory, and a live view image display for monitor display is performed on the display unit 26 (step S01). It is determined whether or not a half-press operation has been performed (step S02), and the process waits for the operation of the shutter key.
[0056]
When it is determined in step S02 that the shutter key has been half-pressed, distance data from the distance measuring sensor 33 to the subject is acquired (step S03), and the focus lens in the lens optical system 12 is converted to the distance data. Move to the corresponding step position (step S04).
[0057]
At this time, an appropriate exposure value is obtained by executing the AE process at the same time, and the aperture value and the shutter speed are set according to the exposure value.
[0058]
Thereafter, it is repeatedly determined whether or not the shutter key has been fully pressed (step S05) and whether or not the shutter key has been half-pressed (step S06). While waiting for the shutter key to be fully pressed.
[0059]
If the half-pressed state of the shutter key is released, this is determined in step S06, the locked state of AF and AE is released, and the process returns to step S01.
[0060]
Then, when it is determined in step S05 that the shutter key has been fully pressed, a photographing process is executed (step S07).
[0061]
At this time, the positioning process of the current position by the GPS receiver 30 is started at the same time, and whether or not there are four or more GPS satellites that can receive the incoming radio wave at that point, that is, in principle, the total of the three-dimensional position and the current time is 4 It is determined whether or not the variable can be calculated accurately (step S09).
[0062]
If arriving radio waves from four or more GPS satellites can be received, it is determined that accurate positioning of the current position can be performed using only the arriving radio waves from the GPS satellites, and only the received content is used. The positioning calculation is executed to acquire three-dimensional position, that is, data of latitude, longitude, and altitude (step S10).
[0063]
Thereafter, the azimuth data of the shooting direction facing the digital camera 10 is obtained from the azimuth sensor 31 and the angle data is obtained from the angle sensor 32 (steps S11 and S12).
[0064]
Next, position (latitude / longitude / altitude) data of the subject at the in-focus position in the three-dimensional space is calculated from the acquired latitude, longitude, and altitude position data, the distance data, the azimuth data, and the angle data. Then, the calculated position data of the subject is recorded and set in the memory card 29 in association with the image data obtained by the photographing process in step S07 (step S14), and a series of photographing-related processes is once performed. The process is completed, and the process returns to step S01 to prepare for the next photographing.
[0065]
If it is determined in step S09 that the number of GPS satellites capable of receiving the incoming radio wave is not four or more but three or less, it is then determined whether or not the number is three (step S09). S15).
[0066]
Here, if it is determined that the number of GPS satellites that can receive the incoming radio wave is three, a positioning operation is performed on the assumption that the altitude data is “0” (0 [m] above sea level), and two-dimensional positioning is performed. The position on the plane, that is, each data of latitude and longitude is acquired (step S16).
[0067]
Next, the altitude data of the current position is acquired from the altitude sensor 34 (step S17), and then the process proceeds to step S11, where the three-dimensional position of the subject is obtained in the same manner as when the incoming radio waves from four or more GPS satellites can be received. Is calculated and recorded and set on the memory card 29 in association with the image data.
[0068]
If it is determined in step S15 that the number of GPS satellites that can receive the incoming radio wave is not three, the current position cannot be calculated by the GPS positioning calculation. While acquiring the altitude data (step S18), the angle data is acquired from the angle sensor 32 (step S19).
[0069]
Then, only the altitude data at which the subject is located is calculated from the distance data to the subject acquired at this time, the altitude data of the current position of the digital camera 10, and the angle data from the digital camera 10 to the subject ( (Step S20), the calculated altitude data of the subject is associated with the image data obtained by the photographing process in step 07, and is recorded and set in the memory card 29 (step S21). Then, the process returns to step S01 again in preparation for the next photographing.
[0070]
As described above, when the accurate three-dimensional position of the subject can be calculated, the position is calculated. When the position cannot be calculated, only the height of the subject is calculated and recorded in association with the image data.
[0071]
Thereby, for example, the three-dimensional position or altitude of a bird on a tree distant from the actual shooting location can be recorded together with image data as an accurate subject position, and can be used for various purposes depending on the idea.
[0072]
In the operation of the above-described embodiment, the three-dimensional position or altitude of the subject is calculated at the time of shooting and recorded in association with the image data. However, various data required to calculate the three-dimensional position or altitude are used. May be recorded directly in association with the image data, and at the time of reproducing the image data, the three-dimensional position or altitude of the subject may be calculated from various data recorded in association with the image data.
[0073]
Further, for example, the processing required for GPS positioning is performed at the time of turning on the power of the digital camera 10, setting of the shooting mode, or periodically, regardless of the operation state of the shutter key. Is executed, the position data or the altitude data acquired in the immediately preceding positioning process may be used.
[0074]
Further, after the photographing of the subject is instructed, various data are obtained, the three-dimensional position or altitude of the subject is calculated, and the data is recorded in association with the image data. The three-dimensional position or altitude of the subject may be obtained and calculated and superimposed and displayed on the through image on the display unit 26. It is possible to cope with cases such as when you want to keep.
[0075]
Also, a map database that stores three-dimensional position information and facility names (names) in association with each other as a built-in or externally connected information processing device such as a personal computer is provided in the digital camera 10. For example, a facility name such as “First Observation Deck of Tokyo Tower” corresponding to the three-dimensional position data is recorded in association with the image data, superimposed on a through image, or displayed at the time of image reproduction. It may be a thing.
[0076]
Further, the digital camera 10 has an active AF function and the configuration in which the distance measurement sensor 33 is provided has been described. However, a passive AF function, for example, a contrast AF function used in many digital cameras has been described. If it has an AF function, it is assumed that distance data is acquired from the drive step position of the focus lens at the time when the contrast is determined to be the highest.
[0077]
In step S09 and step S16, an incoming radio wave from a GPS satellite is received, and a positioning operation is performed based on the received content to obtain a three-dimensional position or a two-dimensional position. Is provided, the reception information (GPS information) received by the GPS receiver 30 is transmitted to an external service center by a communication function, and the service center communicates the three-dimensional position or the two-dimensional position calculated by the positioning based on the GPS information. You may make it acquire by receiving using a function.
[0078]
Further, information necessary for calculating the three-dimensional position or altitude of the subject, such as camera two-dimensional position information (or GPS information), camera altitude information, shooting azimuth information, shooting angle information, shooting distance information, etc. The three-dimensional position or altitude (or corresponding name) of the subject calculated based on the various types of information received by the service center is transmitted to the external service center by the communication function, and is received by the communication function. May be recorded in association with, or superimposed on a through image, or displayed during image reproduction.
In such a configuration, it is not necessary for the camera to calculate the three-dimensional position of the subject, so that the processing load on the camera can be significantly reduced.
In step S14 and step S21, the three-dimensional position or altitude of the subject is recorded in association with the image data. However, when a communication function is provided, the image data and the subject 3 are recorded using the communication function. The dimensional position or altitude may be transmitted to an external recording device.
Further, in addition to the circuit configuration shown in FIG. 1, there is provided an acceleration sensor corresponding to a three-dimensional direction, and sensors having a movable mechanism corresponding to the output of the acceleration sensor, for example, an angle sensor 32 using a gyro sensor. If the digital camera 10 is used in a dynamic state in which an external force such as a centrifugal force is applied, for example, the user of the digital camera 10 can take a picture of another paraglider while gliding with a paraglider. Even in such a case, accurate various data can be obtained and the positioning calculation can be executed.
[0079]
