20090073269 | Imaging apparatus and imaging method - An imaging apparatus and an imaging method supply an optimum amount of image data to another apparatus. When a PDA has a maximum transfer rate of 1.5 Mbps, a mobile phone determines that the maximum speed of communication with the PDA is low, reduces the amount of moving image data captured by a CCD of the mobile phone accordingly, and supplies the captured moving image data to the PDA. The PDA therefore displays a low-quality moving image on its display unit. When the PDA has a maximum transfer rate of 480 Mbps, the CPU of the mobile phone leaves unchanged the amount of moving picture data captured by the CCD and supplies the captured moving image data to the PDA. The PDA then displays a high-quality moving image on its display unit. The foregoing may be advantageously applied to digital cameras. | 03-19-2009 |
