The invention generally relates to wireless camera systems. In particular, the present invention relates to a wireless camera system that includes a camera module and a power module configured to independently or cooperatively transmit data wirelessly to a portable computer device system.
Portable computing devices (PCD) such as smartphones, tablet phones, tablets, etc. have become ubiquitous among industrialized populations. PCDs are characterized by independent communication and computer processing. For example, PCDs include a radio capable of communicating wirelessly over one or more data frequencies (i.e. cellular, Bluetooth, Wi-Fi). PCDs further include computer components which enable the PCD to function independently of other computing devices, including processors, power sources, memory modules, etc.
PCDs include a variety of input components such as cameras, touch screen, biometric sensors, connectors, microphones, etc. which enable a user to input data into the PCD via various mediums. For example, a user may input video or photo data via an integrated camera within the PCD. The PCD may then process and display the video or photo data on an output component such as a display screen. The processing of data may include selective manipulation via various applications, or apps.
Conventional integrated PCD-based camera components are limited in their operation and utility. Most PCDs include one or more integrated photo and/or video camera components. However, the integrated camera components are inherently restricted to a location on the PCD device. Therefore, to capture both an image and view the real-time input of the photo/video component on the display screen of the PCD, a user is inherently limited in positioning and orienting the photo/video component. Likewise, video capture over a period of time is cumbersome by requiring a user to physically position the entire PCD in a manner to capture the desired video view angle.
External camera components such as GO PRO® type devices provide convenient positioning but then require cumbersome data transfer to one or more computing devices. Many external components transfer data onto digital mediums that cannot be directly transferred into a PCD without additional components (i.e. SD Cards). Thus, conventional external cameras do not efficiently transmit data to the PCD while allowing optimum positioning for data recording.
Therefore, there is a need in the industry for a wireless camera system that integrates with a portable computing device to provide optimum positioning and efficient wireless data transfer.
The present invention relates to wireless camera systems, including a camera module and power module which are configured to wireless transmit data to a portable computing device. The portable computer device may be a smartphone, tablet, or tablet phone having a total volume smaller than twenty cubic inches. The camera module may have an outer dimension smaller than three cubic inches and may further include an electrical coupler, secondary battery, lens, image sensor, circuit board, and microphone. The camera module may be configured to generate data from the image sensor or microphone. The power module may have an outer dimension smaller than twenty cubic inches and may further include a primary battery, an electrical input, and a camera receptacle. The electrical input may be configured to receive a direct current to charge the primary battery, and the battery receptacle may include both a physical camera receptacle and an electrical camera coupler. The system may include a coupled state in which the camera module is disposed within the physical camera receptacle and an electrical coupling between the electrical coupler of the camera module and the electrical camera coupler of the power module. The system may include a separated state in which the camera module is physically separate or independent of the power module. The portable computer device may be configured to wirelessly receive the data generated by the camera module. In a first embodiment, the camera module may further include a wireless communication module configured to wirelessly transmit the data to the portable computer device in the separated state. In a second embodiment, the power module may be configured to receive the data from the camera module in the coupled state and wirelessly transmit the data to the portable computer device in the coupled state via a wireless communication module.
Embodiments of the present invention represent a significant advance in the field of wireless camera systems. Conventional external camera systems generally fail to include an integrated wireless transmission system, thereby making the data transfer process cumbersome. Likewise, some external camera systems require a physical wire between the camera module and the portable computer system, making data capture cumbersome. Embodiments of the present invention provide a portable camera system that optimizes both functionality in data capture and transfer to a portable computer device. The first embodiment relates a “smart camera” in which both the data capture and data transmission are handled by the camera module. In the first embodiment, the power module acts as a “dumb component,” serving only to charge the battery in the camera module. The second embodiment relates to a “smart power module” in which the camera module must record the data as it's captured and then directly transfer the data to the power module via an electrical coupling. The power module may then wireless transmit the data to the portable computer device. The novel integration of the camera module and power module to both enable optimum camera functionality and data transfer functionality is not present in the prior art.

It will be appreciated that embodiments of the camera module may incorporate processing of a raw video stream as captured by the image sensor. The steps may include demosiacing, color correction, gamma correction, local contrast enhancement, noise filtering, and sharpening. Video compression may be employed prior to saving the video stream to storage. Video processing and compression are typically the most power intensive operations for a video camera. In order to save power in the camera module, and thus reduce its size, some or all of the processing and compression may be moved to the power module or the PCD. In one embodiment, the camera module would only store raw image sensor data and the power module and/or the PCD would do all the video processing and compression. Alternatively, the camera module may perform only preliminary processing and compression. For example, the camera module may only process motion JPEG to eliminate the need for a DRAM chip on the camera module. In this scenario, the power module and/or the PCD may perform the secondary processing and compression such as completing the compression of the stream. Alternatively, the camera module may perform the majority of the processing and compressing while some minor final processing such as Electronic Image Stabilization (EIS) is performed by the power module and/or PCD.
It should be noted that various alternative system designs may be practiced in accordance with the present invention, including one or more portions or concepts of the embodiment illustrated in
