Abstract

PROBLEM TO BE SOLVED: To provide a camera system with which an image-pickup conditions at image-pickup and an image-pickup state of an image are notified to a user after the photographing. SOLUTION: An image-pickup state of an image is detected (T1), and various state data detected at a point of image-pickup time are analyzed by a corresponding analysis module (T2, T3). Whether or not the analysis result exceeds each corresponding threshold level is checked (T4). The check result which exceeds a threshold level is discriminated to be a defective image and a corresponding state flag is set. All the corresponding status flags of the result with less than the threshold level are reset (T5, T6). Furthermore, whether or not all the state flags are reset is checked (T7), and when all the flags are reset, an OK flag is set on. When any one of them is set, the OK flag is set to off (T8, T9). Then voice data corresponding to the status flags which are set are extracted from a voice data registration list, the data are decoded into voice signals to sound a photographing state message for informing a photographer or the like of the detected photographing state (T10, T11).

[Embodiment of State Detection (A)] An example in which a vibration detecting device is used as an embodiment of the imaging state detecting means 221 to detect a camera shake at the time of imaging by the vibration detecting device and notify after the imaging. State.

FIG. 10 is a block diagram of a main part of the imaging state detecting means 221-1 using the vibration detecting device. The vibration detecting device 60 is provided near the imaging lens 111 of the digital camera body 100 (FIG. 1). I have.

In this embodiment, a vibration detecting device using a piezoelectric element (piezo element) 61 is used as the vibration detecting device 60. In a vibration detecting device using a piezo element as a piezoelectric element, when a distortion force is transmitted to the piezoelectric element by vibration, the piezoelectric element generates a voltage corresponding to the magnitude of the distortion. The signal is converted into a digital signal by the converter 63 and transmitted to the control unit 20.

The vibration detection device 60 is configured to operate only at the time of image capturing because it is difficult to detect a camera shake at the time of image capturing if the device is activated each time the user moves the digital camera 100 ′. For this reason, an image is taken after a time t after the shutter button 37 is pressed, and when the shutter button 37 is not pressed, a signal from the vibration detection device 60 is not accepted, and the time when the shutter button 37 is pressed is not received. Vibration detection device 60
To accept signals from Then, when the vibration value detected by the vibration detection device 60 during the time t after the shutter is depressed is larger than the threshold value λ, it is determined that camera shake has occurred.

FIG. 11 is a flowchart showing an example of an image pickup state notification operation when a camera shake is detected using the vibration detection device. The control unit 20 checks whether or not the shutter button 37 has been pressed (U1).
The signal from 0 is received and compared with a threshold value λ (U2).
The status flag 1 of 0 is turned on and the process proceeds to U6 (U
3). In the above U3, when the signal from the vibration detecting device 60 is equal to or smaller than the threshold λ, it is checked whether or not the time t has elapsed (U3).
4) If the time t has not elapsed, the process returns to U2, and if the time t has elapsed, the imaging state flag 1 is turned off (U5). It is checked whether all the status flags are off (U6). If all the status flags are off, the OK flag is turned on (U7).
The K flag is turned off (U8). The audio data corresponding to the ON state flag of the imaging state detection flag table 80 is extracted from the audio data registration list 452 and sent to the audio output unit 10 (U9). The audio output unit 10 restores the received audio data into an audio signal, outputs an imaging state message as audio, and notifies the imaging person or the like of the detected imaging state (U10).

If the camera shakes due to the above operation, the status flag 1 is turned on in steps U2 to U4.
In step U9, audio data corresponding to the code "01" is extracted from the audio data registration list 425 and sent to the audio output unit 10. In step U10, the received audio data is restored to audio by the audio output unit 10, and the camera shake is performed. There was a camera status message saying "There was a camera shake,
Please retake "is output as a sound and notified to the photographer or the like.

In the above embodiment, the vibration detecting device 60 is configured as a vibration detecting device using a piezoelectric element. However, the vibration detecting device 60 may be configured using a photo sensor. Further, the automatic iris mechanism 11 is operated in the same manner as in FIG.
The light quantity measuring device 2 may be used as an image pickup state detecting means to detect and report the light quantity shortage. In this case, FIG.
When the amount of light detected in steps U2 and U3 is equal to or smaller than the threshold ν, the state flag 3 of the imaging state detection flag table 80 is set.
Is turned on, and if the light amount is larger than the threshold value ν until the time t elapses, the imaging state flag 3 is turned off in step U5.

[Embodiment of State Detection (B)] Signal Processing Unit 1
The color process circuit 3 separates and generates a luminance signal, a color component signal, and the like from the image data.

FIG. 12 is a block diagram showing a configuration example of a color process circuit of the signal processing unit 13. In FIG. 12, the color process circuit 131 includes an R component integrator 1311 and a G component integrator.
It has a component integrator 1312, a B component integrator 1313, an integrator 1314 for AE (auto iris), a filter 1315 for AF (auto focus), an AWB circuit 1317, and a signal combining circuit 1318.

The image signal photoelectrically converted by the CCD is A / D-converted by an A / D converter of the signal converter 12 and input to the color process circuit 131. Color process circuit 13
In step 1, a process for generating an auto iris (AE) signal, an auto white balance (AWB) signal, an auto focus (AF) signal, and Y, Cb, Cr signals is performed on an input signal.

The AE integrator 1314 integrates the input signal and outputs the integrated value. The AF filter 1315 detects a high frequency for contrast autofocus from the input signal.
F), the integrated value of the output is output, and the AWB circuit 1317 outputs an R component integrator 1311 and a G component integrator 1
An integrated value of each component integrated by 312 and B component integrator 1313 is output. These integrated outputs are output to the control unit 2
The control unit 20 outputs a control signal for controlling the gain, the shutter speed, and the lens 111 to be given to the AGC of the signal processing unit 12 based on these signals. Therefore, the color process circuit 131 is used as one of the imaging state detection means 221 as the color process circuit 131.
The imaging state can be detected using the integrated output of.

Hereinafter, as an embodiment of the image pickup state detecting means 221, an example will be described in which image pickup data of the digital camera 100 (integrated output of the color process circuit 131) is used to detect a camera shake at the time of image pickup and notify after image pickup.

FIGS. 13A and 13B are distribution diagrams showing an example of the distribution of the integrated output of the high frequency for AF used for the detection of the camera shake. FIG. 13A is a distribution diagram of the integrated output before time t from the imaging time, and FIG. Distribution map of the integrated output at the time of imaging without
(C) is a distribution diagram of the integrated output at the time of imaging when there is a camera shake, and (d) and (e) are diagrams showing changes in the difference depending on the presence or absence of the camera shake.

Assuming that the integrated output of the AF filter 1315 before time t before the imaging time is Y0-t (a), and that the integrated output when there is no camera shake at the imaging time is Y0 (b),
If there is no camera shake, the difference ΔY of the integrated output during time t =
Y0-Y0-t becomes a constant value C and becomes constant over the entire line as shown in (d). However, if there is camera shake at the time of imaging, the difference ΔY 'between the integrated output Y0-t just before the time t and the integrated output Y'0 at the time of imaging is ΔY' = Y'0-Y0-t.
Varies on the line as shown in (e).

Therefore, the integrated value of the AF high frequency is calculated at time t '.
By sampling every (t ′ ≦ t) and checking whether or not the difference from the previous integral value is within the threshold ρ over one line, it is possible to detect whether or not the image is blurred due to vibrations such as camera shake. . Ideally, the difference ΔY = Y0 between the integrated outputs
The case of −Y0−t = C is the case without camera shake. However, in practice, even if the camera is intended to be fixed by hand, a small vibration occurs during the interval of breathing, etc., and even if the camera is fixed with a device such as a tripod, etc. It is desirable to determine the threshold ρ within the range where vibration can be absorbed in terms of camera performance, taking into account the fact that vibrations of the ground are transmitted, camera structure and resolution, and some practical factors such as slight vibrations can be ignored. .

FIG. 14 is a flowchart showing an example of an image pickup state notifying operation at the time of detecting a camera shake using a high frequency for AF. In the recording mode, an AF signal is output by the color process circuit 131 based on the input image signal, and is integrated by the AE integrator 1314 (V1). The integrated value for one line is recorded in the RAM 22, sampled at each time t ', and the previous and current sampled values are held in the RAM 22 (V2). The control unit 20 checks whether or not the shutter button 37 has been pressed (V3). When the shutter button 37 has been pressed, the difference ΔY between the previous sampling value and the integrated value for one line at the time when the shutter button 37 was pressed is determined. Is compared with the threshold value ρ (V4). If the difference is larger than the threshold value ρ, the state flag 1 of the imaging state detection flag table 80 is turned on and the process proceeds to V7 (V5). The flag 1 is turned off (V6). It is checked whether all status flags are off (V7). If all status flags are off, the OK flag is turned on (V8). If at least one status flag is on, the OK flag is turned off (V8). V9). The audio data corresponding to the ON state flag of the imaging state detection flag table 80 is extracted from the audio data registration list 452 and transmitted to the audio output unit 10 (V10). The audio output unit 10 restores the received audio data to an audio signal, outputs an imaging state message as audio, and notifies the imaging person or the like of the detected imaging state (V11).

According to the above operation, if there is a camera shake, the state flag 1 is turned on in the above-mentioned steps V3 to V5 based on the image pickup data, and in step V10, the state corresponding to the code "01" from the audio data registration list 452 The audio data is extracted and sent to the audio output unit 10. In step V11, the received audio data is restored to audio by the audio output unit 10, and an image capturing state message indicating that there is a camera shake "There was a camera shake, retake Please "is output as a voice and notified to the photographer or the like.

It is to be noted that the out-of-focus state is detected and notified based on the difference between the luminance signal and the distribution of the high frequency for AF within the time t by using the color process circuit 113 as the image pickup state detecting means in substantially the same operation as in FIG. It is also possible to detect and report the insufficient light amount based on the luminance signal at the time of imaging, and to detect and notify the contamination of the image based on the difference (or characteristic) between the color distribution signals before and during the imaging.

The embodiments of the present invention have been described above.
The present invention is not limited to the above embodiment, and it goes without saying that various modifications can be made.

As described above, according to the camera apparatus of the first aspect, the user can know various imaging condition values and external environment conditions set at the time of imaging by displaying or transmitting voice after imaging. Since it is possible to immediately check under what imaging conditions the image was taken after the image was taken, it is possible to quickly take measures such as changing the imaging conditions and retaking the image if the intended image could not be obtained. it can. Further, by adopting a configuration including the imaging environment condition detecting means, it is possible to know the imaging environment conditions such as the temperature and humidity at the time of imaging, which can be useful in the case of creating survey materials and the like. Also, after the shutter is pressed, it takes some time until the image is recorded, but it is possible to notify the imaging condition during the recording operation, so that the image is captured under any imaging condition before the recording is completed. Can be checked immediately after imaging, and the response can be made more quickly.

According to the camera device of the second invention,
The user can know the state of the image at the time of imaging by displaying or transmitting the sound after imaging, so that the user can know good / bad of the captured image without reproducing the image and determine whether or not it is necessary to retake the image. Is simplified. In addition, a detection device that physically detects the state of the image at the time of imaging can be provided, and the imaging state (imaging failure state) of the image can be determined based on the output of the detection devices. Becomes easier. Further, when the state of the image at the time of imaging is determined from data based on image data obtained from a subject image of the camera device, it is not necessary to increase the physical size of the camera device. In addition, by outputting the state of the image at the time of imaging by a voice message, it is possible to know the image state without looking at the display each time. In addition, since it is possible to listen to the voice message and gaze only when the image state is poor, it is possible to reduce troublesome image confirmation for the user. In addition, since the state of the image at the time of imaging is output as a display message, no special device such as an audio output device is required, so that the physical size does not need to be changed. Furthermore, since the operation guidance such as re-taking can be performed simultaneously by the display message, the operation becomes easy for the user.
