The invention discloses a
mobile phone auxiliary portable photographing device with a simplified structure. The portable photographing device comprises an image collection module, a
data transmission module and a second power supply module. The image collection module comprises a lens optical unit, an imaging unit and a collection controller which are connected. The lens optical unit is a lens
system with multi-level lens cones. The imaging unit is a
CMOS system. The
data transmission module comprises an AD converter, a temporary memory and a transmission controller. Through detachable connection between a connection port and a connector, the detachable connection between the temporary memory and a
mobile phone data storage module, and the detachable connection between a
mobile phone power supply, and the second power supply module are formed. Compared with a traditional portable camera, the device has the advantages that the data storage and
processing system is simplified, and the device is lighter and is more portable. Compared with a built-in camera of a mobile phone, the device has the
advantage that better image data is provided.
