DETAILED DESCRIPTION
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is applicable to other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting. As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product.
Now referring to FIG. 1, an embodiment of the present invention uses technology found in cameras (or from other sensing devices) having one or more user-configurable options. For instance, one digital camera model may allow the photographer to change the ISO sensitivity, exposure time, use manual or auto focus methods or a multitude of other configurable options. In some cases a photographer (or other technician) may be focused on a certain scene or task with the camera with a fixed set of options. A short time later the photographer may change scenes or viewpoints but fails to change the necessary camera settings. While the settings may be usable in the new situation, they may not be optimal. If photos are taken of the new scene using the old settings the photographs may be suboptimal.
Other examples include handheld devices such as smartphones or tablet PCs with build in camera function or programmable handheld devices that simply require manual settings prior to use, e.g. devices that allow to measure radiation, gas, temperature or provide any other type of sensor input. In the particular case of photographic sensors, some cameras will attempt to determine the type of scene and make corrections on the fly. However, the photographer who uses manual or semi-manual settings in a changing environment must rely on memory and skill to ensure correct settings. An embodiment of the present invention uses a process to check for dynamic environment element changes.
Still referring to FIG. 1, a process determines at least one setting on a user's device, e.g. a camera and/or video, sensor(s) (110). The process continues by detecting a change in a dynamic environment element that could affect an optimal setting for the determined setting (120). If a change has been detected, the user is notified that a change has occurred (130). The notification may produce audible warnings, flash warning lights or some other else to warn the user that current settings may no longer be optimal. Examples of environmental elements may include light, distance, power for flash or shuttle control, buffer size or some other protocols. Using the camera as example, the dynamic range of a photographic sensor refers to the sensors ability to distinguish detail in (relatively) very bright and very dark areas of a scene. A common technique for extending a camera's dynamic range is to take 2 or more photos of the same (stationary) scene at different exposures. This technique is known as “Bracketing”. During a photo shoot a photographer requires a bracketed sequence for a High Dynamic Range shot. In this case, the settings must be changed to aperture priority to take advantage of the lens depth of field capability. However, in some cases the camera must be set for manual focus. In this case the photographer should be alerted if the angle/distance of the camera changes or if there is a significant change in the scene (light, contrast, etc.).
Referring to FIG. 2, another embodiment of the present invention uses another process for determining at least one setting on a user's device, e.g. a camera, sensor(s) (210). The process continues by detecting a change in a spatial event that could affect an optimal setting for the determined setting (220). If a change has been detected, the user is notified that a change has occurred (230). The notification may produce audible warnings, flash warning lights or some other else to warn the user that current settings may no longer be optimal. Examples of spatial events may include GPS positioning or local orientation. An example may include a device which might be set to operate based on its sensor input and certain customer settings, which was performed at sea level, yet other measurement at higher altitude might render some of the settings obsolete.
Referring to FIG. 3, yet another embodiment of the present invention uses yet another process for determining at least one setting on a user's device, e.g. a camera and/or video, sensor(s) (310). The process continues by detecting a change in timing that could affect an optimal setting for the determined setting (320). If a change has been detected, the user is notified that a change has occurred (330). The notification may produce audible warnings, flash warning lights or some other else to warn the user that current settings may no longer be optimal. An example of a timing event may include shooting sunrise or sunset images. As one familiar shooting such images timing of the shot is important. Usually there is only a small window to capture the image before the current setting becomes less than optimal.
Referring to FIG. 4, still another embodiment of the present invention uses still another process for determining at least one setting on a user's device, e.g. a camera and/or video, sensor(s) (410). The process continues by detecting a change in custom settings that could affect an optimal setting for the determined setting (420). If a change has been detected, the user is notified that a change has occurred (430). The notification may produce audible warnings, flash warning lights or some other else to warn the user that current settings may no longer be optimal. Examples of a custom setting changes include a setting change in both the aperture and shutter settings.
Referring to FIG. 5 an exemplary implementation according to an embodiment of the present invention is depicted. A user's device 500 includes a plurality of sensors 502. The user's device 500 may be a camera, video camera, a smart phone, personal computer or a computer tablet. The internal sensors 502 can include light metering elements, a GPS device, a timing device, and a distance measuring device. One output of the internal sensors 502 element is received by a settings generator 504. The settings generator 504 determines the settings for the user's device 500. An output processing and display unit 510 receives the settings as determined by the settings generator 504. The output processing unit and display 510 then displays the image before the picture is taken. While the output processing and display unit 510 is ready to capture the image, a detection unit 506 also receives current sensor reading signals from the internal sensors 502. If the detection unit 506 detects a change in sensors readings based upon a previous output of settings generator 504 a signal is set to a warning generator 508. The warning generator 508 produces audible and flash warning lights to warn the user that current settings may no longer be optimal. The warning generator 504 also sends a signal to the output processing and display unit 510 to inhibit the capturing of the image unless the user overrides the warning generator 508.
Referring now to FIG. 6, this schematic drawing illustrates a hardware configuration of an information handling/computer imaging system in accordance with the embodiments of the invention. The system comprises at least one processor or central processing unit (CPU) 610. The CPUs 610 are interconnected via system bus 612 to various devices such as a random access memory (RAM) 614, read-only memory (ROM) 616, and an input/output (I/O) adapter 618. The I/O adapter 618 can connect to peripheral devices, such as disk units 611 and tape drives 613, or other program storage devices that are readable by the system. The system can read the inventive instructions on the program storage devices and follow these instructions to execute the methodology of the embodiments of the invention. The system further includes a user interface adapter 619 that connects a keyboard 615, mouse 617, speaker 624, microphone 622, and/or other user interface devices such as a touch screen device (not shown) to the bus 612 to gather user input. Additionally, a communication adapter 620 connects the bus 612 to a data processing network 625, and a display adapter 621 connects the bus 612 to a display device 623 which may be embodied as an output device such as a monitor, printer, or transmitter, for example.
