[0025]

[Table 1]

[0026]

[Table 2]

The voice is input by the voice input unit 107, converted into an electric signal, modulated by the control unit 101, and transmitted by the wireless function unit 103.

The transmitted moving image or still image is received by the wireless communication function unit 103, demodulated by the control unit 101, and then displayed on the display unit 105. Also,
The voice is received by the voice input unit 107, and the control unit 10
After the demodulation processing is performed at 1, the sound is output by the audio output unit 108.

(B) When the battery level is low: By operating the operation unit 106, communication involving image transmission is started. The remaining battery level detector 112 measures the voltage of the battery 109, detects the remaining battery level, and sends the detection result to the remaining battery level indicator 113 and the lower battery level alarm unit 114. During communication, when the remaining battery level decreases and the remaining battery level detected by the remaining battery level detection unit 112 falls below a predetermined value, the low battery level alarm unit causes the remaining battery level to be lower than in normal communication. Differently, an alarm sound is output to the voice output unit 108, and the display unit 10
The alarm is displayed on 5.

Further, the image pickup section 104 photographs a moving picture or a still picture, converts the photographed moving picture or the still picture into a digital signal, and transmits the digital signal to the image data converting section 116 of the control section 101.

In the case of a low battery level alarm, the image data amount setting unit 115 causes the image data converting unit 116 to convert the image data into a preset number of pixels and frames. In the image conversion unit 116, the image data amount setting unit 115
The digital signal from the image pickup unit 104 is converted into image data by performing image processing with a preset number of transmission pixels and a predetermined number of frames according to an instruction from the. For example, according to the first embodiment, as shown in Table 1 and Table 2,
In a moving image, the number of pixels is 50 × 50 dots, and the number of frames is 1 image per second.
Image processing is performed by performing image processing with a pixel number of 50 × 50 dots and a transmission interval of 10 seconds. The image data is transmitted via the wireless function unit 103.

The above processing will be described with reference to FIGS. 3 and 4.
explain. Communication involving image transmission is started (step 301, step 401). When the low battery level alarm is generated (step 302, step 402), if the image data amount of the transmitted image is set to be reduced in advance (step 303, step 403: YE).
S) Then, the image data conversion unit 116 of the control unit 101 reduces the number of pixels and the number of frames to preset values (step 304, step 404).

As for voice, as in the case of normal communication,
It is input to the voice input unit 107, converted into an electric signal, modulated by the control unit 101, and transmitted by the wireless function unit 103.

The transmitted moving image or still image is received by the wireless communication function unit 103, demodulated by the control unit 101, and then displayed on the display unit 1 as in the case of normal communication.
It is displayed on 05. In addition, the voice is received by the voice input unit 107 as in the case of normal communication, and the control unit 101
After the demodulation processing is performed in, the sound output unit 108 outputs the sound.

As described above, when a digital signal of a moving image and a still image taken by the image pickup unit 104 is converted into image data when the low battery level alarm is generated, the process for suppressing the image data is as follows. By performing the process of reducing the number of repetitions of the number of frames by increasing the number of screens transmitted per second for moving images or the transmission interval for still images, and the process of reducing the number of pixels that make up one screen of moving images and still images. Even when the battery level is further reduced, communication involving image transmission is possible.

With the above configuration, even when the battery level is low and a low battery level alarm is generated, the amount of image data to be transmitted can be suppressed based on the battery level. Therefore, even when the remaining battery level is low, it is possible to continue communication with image transmission.

Further, as processing for suppressing the image data amount,
When you want to shorten the time it takes to switch the screen even if you sacrifice the number of pixels of the image to be displayed by having the process of reducing the number of repetitions of the number of frames and the process of reducing the number of pixels that make up one screen of the image. In particular, the convenience when used as a videophone is improved.

In the first embodiment, when the low battery level alarm is issued, the image data conversion unit 116 is activated.

In the first embodiment, the case where the number of pixels and the number of frames of the image set in the image data amount setting unit 115 is one when the communication quality alarm is generated has been described. You may make it possible to set in multiple steps according to the amount. By doing so, it is possible to suppress the data amount of the image to be transmitted according to the remaining battery level.

In the first embodiment, the case where both the frame number setting unit 202 and the pixel number setting unit 201 are provided and both the frame number and the pixel number are changed has been described, but the frame number setting unit 202, Pixel number setting unit 20
One of the two may be provided.

When both the frame number setting unit 202 and the pixel number setting unit 201 are provided, an image data amount setting unit 115 for setting whether to operate at least one of them may be provided. Further, the image data amount setting unit 115 may be able to set at least one of the number of constituent pixels, the number of frames, and the transmission interval.

Further, by the image data amount setting unit 115,
When the number of pixels and the number of frames are set in advance, the display unit 105 may display whether or not the setting is performed. By doing so, it is possible to recognize that the communication accompanied by the image transmission can be continued even when the battery level is reduced during the communication.
