- the first luminance detection unit 203 calculates a first average luminance of the entire image captured by the first imaging unit 201, and outputs the calculated first average luminance to the comparison unit 205. Output.
- the second luminance detection unit 204 calculates a second average luminance of the entire image captured by the second imaging unit 202, and outputs the calculated second average luminance to the comparison unit 205. I do.
- the comparison unit 205 compares the input first and second average luminances, and outputs the comparison result to the control unit 116.
- FIG. 10 is a flowchart showing an antenna switching control processing procedure in the second embodiment.
- This processing program is stored in the ROM in the control unit 116 and is also executed by the CPU in the control unit 116 at predetermined intervals. It should be noted that, instead of being performed every predetermined cycle, if there is a change in the detection result of the first and second detection units or the first and second luminance detection units, the processing may be executed by interrupt processing. Good.
- the open / close detection results of the first detection unit 114 and the second detection unit 115 are acquired (step SI 1).
- the open / close detection result is determined by referring to the table of FIG. 6 (step S12).
- the control unit 1 16 detects the detection result of the first detection unit 1 1 4, and the upper housing 103 has the lower housing 1 0 5 centered on the first axis 106.
- the upper housing 103 is closed with respect to the lower housing 105 around the second shaft 107 as a result of detection by the second detection unit 115.
- the state non-rotation state
- the first antenna 102 is selected to select the first antenna 102.
- a signal for selecting 102 is transmitted to the switching section 117 (step S13).
- step S12 the detection result of the first detection unit 114 indicates that the upper housing 103 is closed with respect to the lower housing 105 around the first axis 106. And the detection result of the second detection unit 115 indicates that the upper housing 103 is closed with respect to the lower housing 105 about the second shaft 107 (no rotation).
- State that is, in the case of closing Z, in which case the mobile radio apparatus 200 is determined to be in the standby state, and the second antenna 104 is selected to select the second antenna 104.
- a signal for selection is transmitted to the switching section 1 17 (step S 14).
- step S12 the result of detection by the first detection unit 114 indicates that the upper housing 103 is opened with respect to the lower housing 105 around the first axis 106. And the detection result of the second detection unit 115 indicates that the upper housing 103 is open to the lower housing 105 about the first shaft 106 (rotational state). ), That is, in the case of the open Z-open, it is determined that the portable wireless device 200 is in the shooting state, and in this case, the comparison result of the comparing unit 205 is further obtained (step S15). Then, as a result of the comparison, it is determined whether or not the first average luminance by the first imaging unit 201 is higher than the second average luminance by the second imaging unit 202 (step S16). If the average luminance of 1 is higher than the second average luminance, select the first antenna 102 (step S 17), otherwise select the second antenna 104 (step S 17) S18). After that, the process ends.
- the first antenna 102 suitable for the call state and the second antenna 104 suitable for the standby state are selected.
- the detection results of the first and second detection units show that the upper housing 103 is opened with respect to the lower housing 105 around the first axis 106 and the second axis 107, respectively.
- the state (rotational state) the first average luminance in the first imaging unit 201 and the second average luminance in the second imaging unit 202 are compared based on the second average luminance. Since the first antenna 102 or the second antenna 104 is selected, the user can select an antenna that is not affected by the hand or finger. As a result, good communication quality can be ensured in various usage forms of the CDMA-type portable wireless device having the biaxial hinge mechanism and the imaging unit.
- the present invention is applied to a CDMA-type portable wireless device, but it is needless to say that the present invention may be applied to a TDMA-type portable wireless device.
- the opening / closing detection results by the first and second opening / closing detection units and the first and second averages by the first and second brightness detection units are provided.
- Antenna selection control is performed using both the luminance comparison result and a straight type portable wireless device (see Figs. 11 and 12) or a portable wireless device with a one-axis hinge mechanism (Fig. 1). 3), the first and second luminance detectors
- the antenna selection control may be performed using only the comparison result of the first and second average luminances according to the above.
- the first antenna 102 is a dipole antenna
- the second antenna 104 is a monopole antenna.
- the specifications of the antenna are not particularly limited. For example, a similar effect can be obtained even if at least one of the first antenna and the second antenna is a built-in antenna such as an inverted F antenna or a patch antenna.
- both of the two antennas 102 and 104 are built-in antennas.
- the present invention is not limited to the built-in antennas.
- the first antenna and the second antenna The same effect can be obtained if at least one of the antennas is an external antenna such as a whip antenna or a helical antenna.
- the external antenna may have elasticity or may not have elasticity.
- the case of two antennas 102 and 104 has been described, but the number of antennas may be three or more. Further, in the second embodiment, two antennas 102 and 104 are arranged one each in the upper and lower housings. However, a plurality of antennas may be arranged only in the upper housing 103 and Multiple pieces may be arranged only on the side casing 105.
- good communication quality can be ensured in various usage modes provided by the biaxial hinge mechanism. Further, good communication quality can be ensured when the imaging device is mounted.
