FIG. 1 is a block diagram showing an embodiment of an electronic camera with a pedometer according to the present invention. The electronic camera with a pedometer shown in FIG. 1 has a pedometer function, and can record pedometer data such as an image signal obtained by the imaging means and a total number of steps obtained by the pedometer on the memory card 28.

That is, the CPU 40 has a counter circuit that controls and controls each circuit of the camera and counts the number of steps. The display unit 46 includes, for example, a liquid crystal display panel, and displays the number of frames that can be shot / the number of frames that can be played back, the remaining battery power of the camera, and the like in the camera mode for shooting. Display pedometer data such as

The vibration detecting section 48 generates a walking detection signal in connection with the walking operation, and also functions as a camera vertical / horizontal detecting means or a camera shake detecting means. Here, the vertical / horizontal detecting means of the camera detects a posture (vertical position or horizontal position) when the camera is held, and the detected vertical position or horizontal position is used to determine the imprint position of the shooting date and time. It is used as information. The camera shake detection means is used in a camera shake correction device that moves an optical member or the like of the camera so as to cancel the camera shake, and includes an angular velocity sensor and the like. The camera shake correction device is effective when an image signal indicating a moving image is externally output from the electronic camera.

When the power of the camera is turned on and the release switch in the operation switch unit 50 is pressed, the CPU
40 detects this and sends a command to the control circuit 34. The control circuit 34 includes the photographing lens driving unit 3
6 and the exposure control is performed by controlling the charge accumulation time in the aperture 12 and the CCD 14. Note that the photographing lens 10 can be zoom-driven by operating a zoom switch or the like.

[0013] CC through the taking lens 10 and the aperture 12
The subject light incident on the light receiving surface of D14
4 is converted into signal charges of an amount corresponding to the amount of light incident on each sensor, and the signal charges are sequentially read out as voltage signals (image signals) corresponding to the signal charges based on clock pulses. The image signal output from the CCD 14 is applied to an analog signal processing circuit 16. The analog signal processing circuit 16 has a CDS clamp, a gain control amplifier, and the like, where sampling of an image signal, white balance adjustment, and the like are performed. The image signal processed by the analog signal processing circuit 16 is supplied to an A / D converter 18.
Are converted into R, G, B digital signals and applied to the digital signal processing circuit 20.

Processing such as conversion into a signal C) is performed, and the YC signal is stored in the memory 22. The YC signal stored in the memory 22 is compressed into a predetermined format by a compression / decompression circuit 26, and the memory card 28 is detachable from the camera.
Will be recorded.

Note that the LCD controller 30 controls the R, G, and R signals based on the YC signal input from the memory 22 during photographing.
A B signal and a pulse necessary for liquid crystal display are generated and output to the LCD panel 32 to display an image on the LCD panel 32. At the time of reproduction, the YC signal read from the memory card 28 and decompressed by the compression / decompression circuit 26 is converted to a YC signal. The reproduced image is displayed on the LCD panel 32 on the basis of this. The YC signal is converted into an analog signal by a D / A converter 24, further converted into a predetermined video signal by an encoder (not shown), and output from a video output terminal to an external device such as a television.

On the other hand, the CPU 40 counts a signal (walking detection signal) related to the walking operation input from the vibration detecting section 48 by an internal counter, and calculates the total number of steps and the pedometer indicating the calorie consumption according to the total number of steps. Display data 46
And the pedometer data is recorded at the time of photographing, and image processing based on the pedometer data is executed at the time of reproduction.

Next, a case where an image captured by the electronic camera with a pedometer of the above configuration is reproduced will be described with reference to a flowchart shown in FIG. CPU40
When a reproduction mode is selected by a mode dial for selecting a mode such as shooting or reproduction, first, it is determined whether or not the number of steps is set by a step setting switch for setting a target number of steps (step S10).

If the number of steps is set, the current total number of steps is compared with the set number of steps (step S12,
S14). Here, if it is determined that the total number of steps is larger than (set number of steps + α) based on the comparison result of the total number of steps and the set number of steps, the process proceeds to step S16, and if it is determined that the total number of steps is smaller than (set number of steps−α). If it is determined that the total number of steps is equal to or less than (set number of steps + α) and equal to or more than (set number of steps−α), the process proceeds to step S20.

In step S16, the total number of steps is greater than the set number of steps + α, and the total number of steps exceeds the target set number of steps by a predetermined number of steps (α). Perform filter processing. The image on which the slim filter processing has been performed is reproduced in step S20. Thereby, the LCD panel 32
, A thin image is displayed (FIG. 3 (A)
reference).

In step S18, (set step count−
α)> total number of steps, and since the total number of steps is smaller than the target set number of steps by a predetermined number of steps (α), wide filter processing is performed so that the image to be reproduced looks fat. The image on which the wide filter processing has been performed is reproduced in step S20. With this, LCD
A fat image is displayed on the panel 32 (see FIG. 3C).

If the total number of steps is within the range of (set number of steps + α) ≧ total number of steps ≧ (set number of steps−α), the slim filter processing and the wide filter processing are not performed. Playback is performed (Fig. 3
(B)). If it is determined in step S10 that the number of steps has not been set, the process proceeds to step S2.
Proceeding to 0, standard image reproduction is performed.

By performing a filtering process on the reproduced image according to the difference between the total number of steps and the set number of steps,
It is possible to inform the user of information equivalent to calorie consumption by walking visually. When displaying the reproduced image, the total number of steps may be displayed on the reproduced image as shown in FIG.

In this embodiment, the target number of steps is set. However, the present invention is not limited to this, and the target calorie consumption may be set. In this case, the set calorie consumption is compared with the calorie consumption calculated from the total number of steps, and filter processing is performed based on the comparison result. In addition, a thin image is obtained by changing the vertical and horizontal magnifications of the image based on the pedometer data, but the image processing is not limited to this. For example, special effect image processing such as morphing, defocusing, and deformation can be considered, and the degree of the special effect is changed based on pedometer data. If there are a plurality of special effect image processing functions, the type of special effect may be selectable.

Further, in this embodiment, the image processing on the reproduced image has been described. However, the image processing described above may be performed on an image to be printed out. The electronic camera with a pedometer has a memory (DRAM) 22 as a primary recording medium and a memory card 2 as a secondary recording medium.
8, but one recording medium is sufficient. Furthermore, the reproduction of the image in this embodiment may be reproduced as an opening screen when the power is turned on. Further, when the reproduction or the power is turned on late at night using the clock information, for example, a filtering process or the like for making the complexion worse may be performed to visually urge the user to go to bed early.
