Abstract
An Internet based camera providing cost-effective higher security and easier and quicker installation by internally determining a degree of quality measure and providing low latency feedback to the installer on adjusting focus.
Claims30
An apparatus comprising:
- an installer indicator device;
- an adjustable image capture device;
- a focus engine circuit;
- a user interface circuit;
- the focus engine circuit coupled to the adjustable image capture device,
- the user interface circuit coupled to the focus engine and to the installer indicator device, whereby an installer can perceive an indication of the degree of quality during the adjustment of the image capture device.
3 more elements
An apparatus comprising
- a user interface circuit, comprising
- an indicator to adjust a digital image capture device,
- an indicator of improving or not improving degree of quality measure, and
- an indicator to stop adjusting the digital image capture device
- a current focus store and a best seen focus store coupled to
- a circuit to determine when the difference between the current focus store value and the best seen focus store value is less than a certain range,
- wherein the best seen focus store is a latch recording the highest value of the current focus store for all adjustments of the digital image capture device;
- and
- a focus engine circuit coupled to the adjustable digital image capture device and coupled to the user interface circuit, comprising
- a high pass filter coupled to the adjustable digital image capture device and
- a comparison circuit coupled to the input of the high pass filter and to the output of high pass filter, and
- means for storing the output of the comparison circuit into the current focus store,
- whereby the high pass filter detects the sharpness of edges and when compared with a sum of the same image provides a degree of quality measure;
- and
- the adjustable digital image capture device coupled to the user interface circuit.
12 more elements
A method for operating an Internet-based camera, the method comprising the following steps:
- cueing an installer through an indicator to begin adjusting digital image capture device,
- cueing an installer through an indicator to stop adjusting digital image capture device, and
- concluding a first client session and initiating a second client session comprising transmitting a camera status and a status on the command to focus the camera received in the first client session.
An Internet-based camera apparatus comprising:
- a network interface whereby a client session may be established with a server to transmit status and request commands,
- at least one output indicator whereby an installer receives feedback on his recent inaction or action,
- a user interface driver circuit coupled to at least one output indicator and further coupled to a focus engine circuit,
- the focus engine circuit coupled to a digital image capture device and further coupled to the network interface and to the user interface driver circuit, wherein the focus engine circuit comprises
- a comparison means,
- an image summing means, and
- a high pass filter.
4 more elements
An internet-based digital camera comprising
- means to switch between normal and optimization modes,
- means to detect relative quality, and
- means to provide feed back to a user on the relative quality, whereby the user is cued to optimize quality within a tolerance range.
