Abstract: An image capturing device, a depth information generation method and an auto-calibration method thereof are provided. The methods are adapted to an image capturing device having dual lens without pre-alignment and include the following steps. A scene is captured by using the dual lens to generate a first image and a second image. First feature points and second feature points are respectively detected from the two images to calculate pixel offset information between the two images, and a rotation angle between the two images are obtained accordingly. An image warping process is performed on the two images according to the pixel offset information and the rotation angle to generate a first reference image and a second reference image aligned with the first reference image. Depth information of the scene is calculated or a stereoscopic image is generated according to the first reference image and the second reference image.

Abstract: A mobile communication device with camera comprises a mobile communication module, a camera module, a storage unit, a display unit, and a switching module. The mobile communication module has a first transmission interface, the camera module has a second transmission interface; image data processed that are outputted by means of the camera module via the second transmission interface, and next the image data outputted that are received by the mobile communication module via the first transmission interface, and next the image data received that are transmitted to the storage unit to be stored and to the display unit to be displayed. The switching module is installed in the mobile communication module for switching to the camera module operation or the mobile communication module operation.

Abstract: A portable electronic device with an operation mode determined in accordance with power consumption and an operation mode switching method thereof are proposed. The method examines the voltage required by different systems to control every power system independently. By examining the capacity of a battery cell unit and comparing the capacity result with a first reference capacity and a second reference capacity, whether to offer operation power in order to operate a mobile communication module or a digital camera module is determined. Therefore, when a digital camera module, which has high power consumption requirements, is off, the mobile communication module can still operate to effectively use energy provided by the power supply unit.

Abstract: A portable electronic device with a power saving function includes a portable electronic system, a DSC (Digital Still Camera) system, and a transmission interface. The portable electronic system has a first process unit, the DSC system has a second process unit, and the transmission interface is electrically connected between the first process unit of the portable electronic system and the second process unit of the DSC system. Whereby, when using the DSC system, the portable electronic system gets into a power saving mode, and when needing to use the portable electronic system, the DSC system outputs a trigger signal to the portable electronic system via the transmission interface to wake the portable electronic system up.

Abstract: A portable electronic device for sharing a common storage device via a by-pass mode is disclosed. The portable electronic device includes a portable electronic system, a DSC (Digital Still Camera), and a mass storage system. The portable electronic system has a first process unit and a signal multiplexer electrically connected with each other. The DSC system has a second process unit. The DSC system is electrically connected with the signal multiplexer. The mass storage system is electrically connected with the signal multiplexer. Whereby, when a raw image signal is captured via the DSC system, the raw image signal is processed via the second process unit to obtain a predetermined image signal. The predetermined image signal is then stored in the mass storage system via the signal multiplexer.
