1. Technical Field
This disclosure is related to image capture and image capture devices.
2. Description of the Related Art
The ability to capture digital images/video using portable computing devices is highly desirable. However, digital cameras that are often built into portable devices are limited in their functionality and modularity.
According to the U.S. Federal Communications Commission (FCC) Code of Federal Regulations (CFR) Title 47 Part 2.1093(b), a portable device is defined as “a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user.” Additionally, portable computing devices exclusively rely on a wireless communications connection (as opposed to a physical/cabled connection) to facilitate communication functionality with other devices and communication networks. Common computing devices such as most laptop personal computers, desktop personal computers, and other computing terminals are not considered portable devices by this definition.
Portable computing devices such as smartphones, internet-connected multimedia devices, and tablet computers have powerful computing capabilities and are able to provide much of the functionality previously possible only with non-portable computing devices such as those described above. Most portable computing devices are also able to provide additional useful functionality such as real-time communication and data collection, and many of these devices have integrated camera and lens assemblies able to capture still digital images and video images as well.
Peripheral digital camera systems connectable to non-portable computing devices are already commercially available to consumers. Some of these devices provide specialized functionality by utilizing high magnification optical systems, integrated light sources, or modular light guide caps. Examples include those proposed in U.S. Pat. No. 4,930,951 to Mitsubishi Kasei Co., et al. (1990), and U.S. Pat. No. 5,442,489 to Scalar Co. et al. (1995). A similar product, “Handheld Digital and Optical Microscope Item #44306” was a peripheral digital camera system produced by Celestron, LLC. Similarly, several peripheral camera products provided by Scalar Co. and Ken-A-Vision Mfg. Co., Inc. have also been made available for purchase.
A peripheral microscope camera connectable to portable terminals is proposed in U.S. patent application 2011/0085032 to LG Innotek Co., Ltd. (2011). This device is specifically designed for use as a microscope camera.
Furthermore, many portable computing devices are able to capture, store, retrieve, share, annotate, and edit images and/or video collaboratively with other computing devices and output devices, as proposed in U.S. patent application 2010/0333194 to C. Ricordi, S. Sikes, S. Sanders, N. Tsinoremas (2009). The ability of portable computing devices to communicate with accessory devices using wireless communication methods has also been detailed in U.S. patent application 2010/023552 to Apple Inc. (2010).
Most if not all existing peripheral digital camera systems which applicants are aware of are unable to connect to portable computing devices, are not able to attach modular lenses, are not able to mount to standard microscopes, are not able to provide illumination to imaging subjects, do not provide digital input/output (I/O) interfaces to their accessories, and/or are not able to simultaneously charge the battery packs of either or both the peripheral camera system and the portable computing device.
The peripheral microscope camera described above, does not contain a battery power source in the camera module, and does not provide for modular lens attachment. Thus, this device is also limited in its functionality.
Digital cameras integrated into portable computing devices heretofore known, peripheral digital cameras connectable to non-portable computing devices heretofore known, and digital cameras connectable to portable terminals heretofore known suffer from one or more of the following disadvantages.
(a) The position of cameras built into portable computing devices is usually fixed or limited, requiring users to reposition the entire portable computing device when aiming the camera, thus negatively impacting user ability to access or interact with the portable computing device controls and output.
(b) The ability to mount, constrain, or environmentally isolate cameras built into portable computing devices is limited by the physical size, shape, mass, and configuration of the portable computing device.
(c) Optical characteristics such as image resolution, field of view, focal length, optical filtering characteristics, and target illumination are limited by the size, optics, and physical configuration of the portable computing device.
(d) The ability to capture images or video over long periods of time is limited by the battery capacity of the connected portable computing device.
(e) The ability to simultaneously charge the battery packs of either or both the peripheral camera system and the portable computing device while capturing images or video is not provided.
(f) The ability to control, send data to, and receive data from accessories attached to peripheral camera systems via a digital input/output (I/O) interface is not provided.
(g) The ability to capture, store, retrieve, share, annotate, control, and edit images, video, and/or data with other portable computing devices and accessories, while also displaying images, video, and/or processed information on external viewing devices, is limited by the availability of secondary or tertiary wireless communication modules in the interconnected devices and accessories.
(g) The ability to remotely control or interact with other portable computing devices and accessories, while also displaying images, video, and/or processed information on external viewing devices, is limited by the availability of secondary or tertiary wireless communication modules in the interconnected devices and accessories.
(h) The ability to connect, receive input from, or provide output to one or more input devices or output devices (e.g., sensors, actuators, control systems, annunciators, display devices, etc.), either in addition to or in place of an image sensor.

External power supply 120 may then be removably electrically connected or coupled to camera module subassembly 200a by engaging DC power connector 122 into DC power receptacle 206. In the event that external power supply 120 is also connected to mains electrical power via power plug 128, the battery within portable computing device 100 as well as the battery pack 236 may be charged.

As engaged by software operating on portable computing device 100 or by engagement of camera input device 218, images may then be captured and digitally converted (digitized) by image sensor 228. A continuous or intermittent stream of individually captured images over a given period of time may be considered a video stream, and may be transmitted in a similar fashion as individual images. Image(s) may then be transmitted via power/data cable 208 to portable computing device 100 to be displayed, saved, manipulated, and/or retransmitted to other computing devices by resident software applications.
