     DETAILED DESCRIPTION  
      One skilled in the art will recognize that the herein described components (e.g., steps), devices, and objects and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are within the skill of those in the art. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar herein is also intended to be representative of its class, and the non-inclusion of such specific components (e.g., steps), devices, and objects herein should not be taken as indicating that limitation is desired.  
       FIG. 1  depicts one implementation of an exemplary environment in which the methods and systems described herein may be represented. In the depicted exemplary environment  100 , illustrated are a variety of exemplary sensors: a digital video camera  102  operated by one or more users represented by user  104 , where the digital video camera  102  may have a capability to record audio input; a digital video camera  106  used in conjunction with a digital still camera  108 , where the digital video camera  106  and/or digital still camera  108  may either or both have a capability to record audio input, both operated by one or more users represented by user  110 ; and a sensor suite  112  comprising more than one sensor represented by sensor  114  and sensor  116  (wherein the sensors  114  and  116  may be but need not be physically co-located, and may be but need not be of the same type, e.g., sensor  114  may be an infrared device and sensor  116  may be a radar device, or, e.g. sensor  114  may be a microphone and the sensor  116  may be an infrared/visible light device), the sensor suite being operated by one or more users represented by user  118 . Taken by themselves, each of the sensors  114  and  116  are exemplary of single independent sensors, and further, either of the sensors  114  or  116  may be audio sensors. The exemplary sensors may represent a variety of devices for the detection and/or the recording and/or the transmission of imagery aspects, e.g., images, and/or audio aspects, e.g., instances of particular voices and/or instances of particular sounds, including but not limited to microphones, digital video cameras, digital still cameras, digital sensor (e.g. CCD or CMOS) arrays, and radar sets. The exemplary users  104 ,  110 , and/or  118  may, for example, operate the exemplary sensors manually or may supervise and/or monitor their automatic operation. The exemplary users  104 ,  110 , and/or  118  may operate the exemplary sensors in physical proximity to the sensors or remotely. The exemplary sensors may also operate autonomously without exemplary users  104 ,  110 , and/or  118 .  
      The exemplary sensors may be used to detect and/or record and/or transmit images and/or sounds and/or other data related to a wide variety of objects, represented in  FIG. 1  by exemplary objects, a sphere  120  and a cube  122 . The sphere  120  and/or the cube  122  may be reflectors and/or emitters of electromagnetic radiation such as visible light and/or microwaves, reflectors and/or emitters of particulate radiation such as electrons and/or neutrons, and/or reflectors and/or emitters of sonic energy. The sphere  120  and the cube  122  are representative of any object(s) or groups of objects, images and/or emitting and/or reflecting sources of sounds and/or other related data which may be detectable and/or recordable and/or transmissible by the exemplary sensors, including but not limited to persons, animals, buildings, roads, automobiles, trucks, aircraft, ships, spacecraft, landscape and/or seascape features, vegetation, and/or celestial objects. When used together in any given example herein, the exemplary sphere  120  and the exemplary cube  122  generally represent two distinct objects which may or may not be of the same or of a similar type, except where otherwise required by the context, e.g., a sphere  120  and a cube  122  used together in an example may represent a first particular object and a second particular object, e.g., a particular person and a particular building, or a particular first aircraft and a particular second aircraft, respectively. When used alone in any given example herein, the designated exemplary object, e.g., the sphere  120  or the cube  122 , generally represents the same object, except where otherwise required by the context, e.g., a sphere  120  used alone in an example generally represents a single object, e.g., a single building, and a cube  122  used alone generally represents a single object, e.g., a particular person.  
      Each of the exemplary sensors may detect and/or record and/or transmit images and/or sounds and/or other related data of the exemplary objects in a variety of combinations and sequences. For instance, the digital video camera  102  may detect and/or record and/or transmit an image and/or sound and/or other related data of the sphere  120  and then an image and/or sound and/or other related data of the cube  122  sequentially, in either order; and/or, the digital video camera  106  may detect and/or record and/or transmit a single image and/or sound and/or other related data of the sphere  120  and the cube  122  together.  
      Similarly, the digital video camera  106  may detect and/or record and/or transmit an image and/or sound and/or other related data of the sphere  120  and of the cube  122  sequentially, in either order, and/or of the sphere  120  and the cube  122  together, before, after, partially simultaneously with, or simultaneously with an operation of the digital still camera  108 . The digital still camera  108  may detect and/or record and/or transmit an image and/or sound and/or other related data of the sphere  120  and of the cube  122  sequentially, in either order, and/or of the sphere  120  and the cube  122  together, before, after, partially simultaneously with, or simultaneously with an operation of the digital video camera  106 .  
      Similarly, the sensor  114  and the sensor  116  of the sensor suite  112  may detect and/or record and/or transmit an image and/or sound and/or other related data of the sphere  120  and of the cube  122  sequentially, in either order, and/or of the sphere  120  and the cube  122  together, before, after, partially simultaneously with, or simultaneously with respect to each other.  
      Such images and/or sounds and/or related data may be recorded and/or transmitted via a computer or computers represented by the network  124  and/or directly to a processor  126  and/or processing logic  128 , which accept data representing imagery aspects and/or sounds and/or related data pertaining to the exemplary objects. The processor  126  represents one or more processors that may be, for example, one or more computers, including but not limited to one or more laptop computers, desktop computers, and/or other types of computers. The processing logic  128  may be software and/or hardware and/or firmware associated with the processor  126  and capable of accepting and/or processing data representing imagery and/or sounds and/or other related data aspects of the exemplary objects from the exemplary sensors and from memory in the case of data stored in memory. Such processing may include but is not limited to comparing at least a portion of the data from one sensor with at least a portion of the data from the other sensor, and/or applying a mathematical process and/or heuristic process to at least a portion of the data from one sensor with at least a portion of the data from the other sensor, and/or accepting input related to the analysis, manipulation, and/or retention of data from the sensors, including but not limited to live, substantially live, and/or retained data, e.g., stored in memory. Such processing may also include, but is not limited to, deriving third data from the combining at least a portion of the data from one sensor with at least a portion of the data from another sensor.  
      The digital video camera  102 , the digital video camera  106 , the sensor  114  and/or the sensor  116  (operating as components of sensor suite  112  or separately as single independent sensors) may be capable of detecting and/or recording and/or transmitting information representing audio input and accepting input representing information for the manipulation and/or retention of such audio information, including but not limited to accepting input for a designation of a reference designator in a video/audio data stream (e.g., a data stream including video and/or audio information) originating from one of the exemplary sensors via detection and/or transmission and/or playback; accepting input for a designation of a temporal beginning designator and/or a beginning demarcation designator in such a video/audio data stream; accepting input for a designation of a temporal ending designator and/or an ending demarcation designator in such a video/audio data stream; and accepting input for retaining at a high resolution a portion of such a video/audio data stream beginning substantially at the temporal beginning designator and/or the beginning demarcation designator and ending substantially at the temporal ending designator and/or the ending demarcation designator. Such input may include confirmation of previous input. Further, the processor  126  and/or the processing logic  128  may be capable of receiving such a video/audio data stream from the exemplary sensors and/or from other computing resources and/or capable of playback of such a video/audio data stream that has been previously retained within the processor  126  and/or the processing logic  128  and/or elsewhere. In addition, processor  126  and/or the processing logic  128  may be capable of accepting input representing information for the manipulation and/or retention of such audio information, including the input described herein in connection with the exemplary sensors.  
      In accepting input, an embodiment may accept input initiated in a variety of ways, including but not limited to initiation by one or more human users such as the users  104 ,  110 ,  118 , and/or  130 ; by the action of one or more processors and/or processing logic integral with, associated with, and/or operably coupled to a device such as the digital video camera  102 ; by the action of a one or more processors such as the processor  126  and/or by processing logic such as the processing logic  128 ; and/or by a combination of human and processor/processing logic interaction, such as a user  130  interacting with the digital still camera  108  and/or the processor  126  and/or the processing logic  128 .  
      Accepting input from one or more human users such as the users  104 ,  110 ,  118 , and/or  130  may include but is not limited to accepting input initiated by interaction with various interface devices such as computer mouse devices, keyboards, and graphical user interfaces; with interface devices that detect sound, such as microphones; with interface devices that detect electromagnetic radiation, such as visible and/or infrared light sensors and cameras; and with interface devices that present visual interface features such as graphical user interfaces.  
      Accepting input initiated by the action of one or more processors and/or processing logic, such as the processor  126  and/or the processing logic  128  may include but is not limited to accepting input initiated by a processor and/or processor logic analysis of a data stream including detection of video/imagery/audio data that satisfies certain conditions and/or parameters that require or indicate the usefulness of designation of those aspects or of reference points indicating the presence and/or limits of those aspects. For example, the processor  126  and/or the processing logic  128  may, in an analysis of a video/imagery/audio data stream, whether the stream be live, substantially live, or retained data, detect the beginning of voice of a particular person of interest whose vocal characteristics are available to the processor  126  and the processing logic  128  and which are used to define detection/recognition parameters, and the processor  126  and/or the processing logic  128  may, upon detection of the voice using those parameters, initiate input to designate a portion of the data stream including the voice for retention.  
      Accepting input initiated by a combination of human and processor/processing logic interaction, such as a user  130  interacting with the digital still camera  108  and/or the processor  126  and/or the processing logic  128 , may include but is not limited to a user such as user  110  interacting with the digital video camera  106 , the processor  126 , and the processing logic  128  to review a video/imagery/audio data stream, detect video/imagery/audio aspects of interest such as images and voices of particular people and to designate for retention, command retention of, and retain those aspects of interest.  
      With regard to accepting input designating a video/imagery aspect and/or an audio aspect of a video/audio data stream, such input may represent an indication from an exemplary user  104 ,  110 ,  118 , and/or  130 , or from the processor  126  and/or the processing logic  128 , of a video/imagery aspect and/or an audio aspect, e.g., video/imagery/audio information of interest, such as a particular human voice or a particular mechanical sound, e.g., an auto engine, or the relative absence of sound, such as a relative silence between two human speakers or two musical phrases, and/or an image of a particular person of interest. Such designation may be for the purpose or purposes of, e.g., retention at high resolution, interactive review of the portion of the video/audio data stream of interest, or analysis of the portion of interest. A video/imagery aspect and/or an audio aspect may be characterized at least in part by a temporal beginning, a temporal ending, an intensity and/or range of intensities and/or distribution of intensities, a frequency and/or range of frequencies and/or distribution of frequencies.  
      With regard to input for a designation of a reference designator in a video/audio data stream, such input may represent an indication from an exemplary user  104 ,  110 ,  118 , and/or  130 , or from the processor  126  and/or the processing logic  128 , of video/imagery/audio information of interest, such as a particular human voice or a particular mechanical sound, e.g., an auto engine, or the relative absence of sound, such as a relative silence between two human speakers or two musical phrases, or an image of a particular object of interest. The reference designator may be designated in the video/audio data stream such that it falls within and/or references a place within the portion of the video/audio data stream comprising the particular video/imagery/audio aspect of interest. The reference designator may be designated via initiating input in a variety of ways, including but not limited to pressing a button on a computer interface device, manipulating features of a graphical interface such as pull-down menus or radio buttons, speaking into a microphone, and/or using the processor  126  and/or the processing logic  128  to initiate automatically such input when the data in a video/audio data stream satisfies some criteria for video/imagery/audio data of interest.  
      With regard to input for designation of a temporal beginning designator and/or a beginning demarcation designator in a video/audio data stream, such input may represent an indication from an exemplary user  104 ,  110 ,  118 , and/or  130 , or from the processor  126  and/or the processing logic  128 , of a point in the video/audio data stream at which a portion of interest of the video/audio data stream begins, such as (but not limited to) the end a relative silence (e.g., silence except for background and/or artifact noise) occurring last before a designated reference designator, the beginning of the sound of interest or of one or more of the sounds accompanying a sound of interest, or the end of a sound occurring last before a designated reference designator, or the beginning of a video image of a particular person of interest. The temporal beginning designator and/or the beginning demarcation designator may be designated in the video/audio data stream such that it falls within and/or references a place at or near the beginning of the portion of the video/audio data stream comprising the particular sound of interest. The temporal beginning designator and/or the beginning demarcation designator may be designated via initiating input in a variety of ways, including but not limited to pressing a button on a computer interface device, manipulating features of a graphical interface such as pull-down menus or radio buttons, speaking into a microphone, and/or using the processor  126  and/or the processing logic  128  to initiate automatically such input when the data in a video/audio data stream satisfies some criteria for demarcation of video/imagery/audio data of interest.  
      With regard to input for designation of a temporal ending designator and/or an ending demarcation designator in a video/audio data stream, such input may represent an indication from an exemplary user  104 ,  110 ,  118 , and/or  130 , or from the processor  126  and/or the processing logic  128 , of a point in the video/audio data stream at which a portion of interest of the video/audio data stream ends. The temporal ending designator and/or the ending demarcation designator may represent the point in the video/audio data stream falling at the end of a portion of interest, such as (but not limited to) the end of the presence of an image of a vehicle of interest, the end a relative silence (e.g., silence except for background and/or artifact noise) occurring just after the end of the sound of interest or of one or more of the sounds accompanying a sound of interest, or the end of a sound occurring just after a designated reference designator. The temporal ending designator and/or the ending demarcation designator may be designated in the video/audio data stream such that it falls within and/or references a place at or near the end of the portion of the video/audio data stream comprising the particular sound of interest. The temporal ending designator and/or the ending demarcation designator may be designated via initiating input in a variety of ways, including but not limited to pressing a button on a computer interface device, manipulating features of a graphical interface such as pull-down menus or radio buttons, speaking into a microphone, and/or using the processor  126  and/or the processing logic  128  to initiate automatically such input when the data in a video/audio data stream satisfies some criteria for video/imagery/audio data of interest.  
      With regard to input for retaining at a high resolution a portion of a video/audio data stream, including but not limited to a video/imagery/audio aspect of a video/audio data stream, such high resolution retention includes but is not limited to storage of a relatively large amount of data, compared to storage of portions of the data stream not selected for high resolution retention, as described herein. Such input may include but is not limited to designation of a high resolution value, e.g., 0.5 MB/second, and/or frequency spectrum characteristics, e.g., lower and upper frequency cut-offs. For example, the user  130  may provide input to the processor  126  and/or the processing logic  128  to identify a portion of a video/audio data stream for retention at high resolution, e.g., input designating an audio aspect of a video/audio data stream and/or input designating a video/imagery aspect of a video/audio data stream. The processor  126  and/or the processing logic  128  may accept the input, enabling the identified portion (e.g., a designated audio aspect) to be stored with high fidelity relative to the source video/audio and with a relatively small proportion of data (if any) discarded, while the portion or portions not selected for high resolution retention may be stored at a relatively lower resolution, e.g., with a relatively higher proportion of data discarded, e.g., to save storage resources.  
      Retention of a portion, e.g., a video/imagery/audio aspect, of a video/audio data stream at a relatively high resolution and retention of portions of the video/audio data stream not included in the portion designated for retention at the high resolution may result in storage of the portion not included in the portion to be retained at the high resolution at one or more resolutions that do not use all of the data available, such that the portion not to be retained at the high resolution is degraded in storage. Degradation of a portion not included in the portion retained or designated for retention at high resolution may be achieved by retaining the not-included portion at one or more lower resolutions, where the one or more lower resolutions may be a function of the distance in the video/audio data stream between the portion to be retained at a high resolution and the portion to be retained at one or more lower resolutions, including but not limited to degrading blocks of data not included in the high resolution portion according to their distance from the high resolution portion (e.g., degrading to one lower resolution a portion between 0 and 60 seconds from the high resolution portion, and degrading to another, even lower resolution a portion between 60 and 120 seconds from the high resolution portion, and so on). One or more inputs may be accepted to set one or more rules by which a portion of a video/audio data stream not included in a portion designated for high resolution retention is degraded and/or retained at one or more lower resolutions. One or more inputs for degradation may be accepted to specify parameters including but not limited to one or more specific resolution values (e.g., 12 kB/sec and/or 20 kB/sec), one or more frequency range characteristics, and/or one or more frequency distribution characteristics. Degradation to one or more lower resolutions may be correlated to one or more specified frequency ranges and/or one or more specified frequency distribution characteristics, such as specific lower resolutions for all sounds above 100 Hz, and/or between 2 kHz and 20 kHz, and/or below 5 kHz, and/or one or more specific lower resolutions for all sounds conforming to a specific frequency distribution characteristic of a particular human voice or musical instrument, and/or, with regard to video/imagery, specific lower resolution for parts of a video/audio data stream that do not include video/imagery of a particular color range. Degradation to one or more lower resolutions may be correlated to the time frame in which a portion of a video/audio data stream has been detected and/or recorded and/or transmitted and/or stored, e.g., video/audio data detected and/or recorded and/or transmitted and/or stored within a week may be retained at the resolution at which it was detected and/or recorded and/or transmitted and/or stored, while data detected and/or recorded and/or transmitted and/or stored between one and two weeks ago may be degraded to 80% of the resolution at which it was detected and/or recorded and/or transmitted and/or stored, and data detected and/or recorded and/or transmitted and/or stored between two and four weeks ago may be degraded to 60% of the resolution at which it was detected and/or recorded and/or transmitted and/or stored, and so on. One or more inputs may be accepted to confirm previous inputs or default values related to degrading data and/or retaining such data at a relatively lower resolution value. One or more inputs may be accepted for degrading a portion of a video/audio data stream not included in a portion designated for retention at high resolution. Inputs may include but not be limited to tactile, sonic, and/or visual inputs. Such an input may be initiated by an action by a user  104 ,  110 ,  118 , or  130 , e.g., pressing a mouse button and/or speaking into a microphone, or the input may be initiated by operation of some hardware/software/firmware, e.g., audio processing software such as the processor  126  and/or the processing logic  128 , or it may be initiated by some combination of human and automated action.  
      In addition to accepting inputs for degrading to at least one lower resolution a portion of a video/audio data stream not included in a portion designated for retention at high resolution, degrading and/or retaining at a lower resolution a portion of a video/audio data stream not included in a portion designated for retention at high resolution may also be performed. Retention at one or more lower resolutions may be performed, e.g., by using one or more memory locations associated with and/or operably coupled to the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or the processing logic  128 . Degradation may be performed by methods including but not limited to data compression and/or data redaction.  
      With respect to this example, input for the identification of a particular portion for retention at a relatively higher resolution does not preclude input for the storage of a distinct and/or an overlapping portion of the data stream at a distinct higher resolution compared to the retention resolution of one or more portions not identified for retention at a higher resolution, e.g., one or more portions of a data stream may be identified for retention at one or more relatively high resolutions. Similarly, input for the identification of a particular portion for retention at a relatively lower resolution does not preclude input for the storage of a distinct and/or an overlapping portion of the data stream at a distinct lower resolution compared to the retention resolution of one or more portions identified for retention at a higher resolution, e.g., one or more portions of a data stream may be identified for retention at one or more relatively lower resolutions.  
      Further, a video/imagery aspect may be designated for retention or retained at a particular resolution on the basis of a presence or absence of some audio aspect of a video/audio stream, and an audio aspect may be designated for retention or retained at a particular resolution on the basis of a presence or absence of some video/imagery aspect of a video/audio stream. For instance, the presence of an image of a particular person of interest in a video/audio data stream may serve as the basis for a designation of an audio aspect of the video/audio data stream for retention at high resolution, and vice versa.  
      A particular portion identified for retention at a high or a low resolution may include more than one data set that may generally be considered to constitute a “frame” in a video/audio data stream. With respect to this example, digital video cameras  102  and/or  106  are representative of any sensor or sensor suite capable of detecting and/or recording and/or transmitting video/audio input as one or more data streams representing the video/audio information. Such input may be initiated in a variety of ways, including but not limited to pressing a button on a computer interface device, manipulating features of a graphical interface such as pull-down menus or radio buttons, speaking into a microphone, and/or using the processor  126  and/or the processing logic  128  to initiate automatically such input when the data in a video/audio data stream satisfies some criteria for video/imagery/audio data of interest.  
      With regard to retaining at a high resolution a portion of a video/audio data stream, e.g., a video/imagery/audio aspect of the video/audio data stream, such retention may include storage in computer memory, such as memory associated with and/or operably coupled to the processor  126  and/or the processing logic  128 .  
      The exemplary sensors may be capable of detecting and/or recording and/or transmitting one or more imagery and/or sound and/or other related data aspects of the exemplary objects, the one or more imagery aspects and/or sound and/or other related data aspects being defined in part, but not exclusively, by exemplary parameters such as focal length, aperture (f-stop being one parameter for denoting aperture), t-stop, shutter speed, sensor sensitivity (such as film sensitivity (e.g., film speed) and/or digital sensor sensitivity), exposure (which may be varied by varying, e.g., shutter speed and/or aperture), frequency and/or wavelength, focus, depth of field, white balance (and/or white point, color temperature, and/or micro reciprocal degree or “mired”), signal/noise ratio, an identified voice of a person or machine, and/or flash (sound aspects are described elsewhere herein). Some or all of the parameters that may define at least in part imagery and/or sounds and/or other related data aspects may have further defining parameters. For example, a frequency and/or wavelength parameter may be associated with one or more bandwidth parameters; and a flash parameter may be associated with one or more parameters for, e.g., duration, intensity, and/or special distribution. Note that although certain examples herein discuss bracketing and/or imagery aspects and/or exemplary parameters in the context of more or less “still” images for sake of clarity, techniques described herein are also applicable to streams of images, such as would typically be produced by digital video cameras  102 / 106  and thus the use of such, and other, exemplary terms herein are meant to encompass both still and video bracketing/aspects/parameters/etc. unless context dictates otherwise. For instance, the bracketing might include bracketing over, say, 20 frames of video.  
      Each of the exemplary sensors may detect and/or record and/or transmit one or more imagery aspects and/or sound aspects and/or other related data aspects of an exemplary object at more than one setting of each of the available parameters, thereby bracketing the exemplary object. Generally, “bracketing” includes the imagery technique of making several images of the same object or objects using different settings, typically with a single imagery device such as digital video camera  106 . For example, the digital video camera  106  may detect and/or record and/or transmit a series of imagery aspects of the cube  122  at a number of different f-stops; before, after, partially simultaneously with, and/or simultaneously with that series of imagery aspects, another digital video camera  106  and/or another type of sensor, such as sensor  114  may detect and/or record and/or transmit a series of imagery aspects of the sphere  120  and of the cube  122  at a number of different white balances. The processor  126  and/or the processing logic  128  may then accept, via the network  124  or directly, data representing the imagery aspects detected and/or recorded and/or transmitted by the digital video cameras  106  or by the digital video camera  106  and the sensor  114 . The processor  126  and/or the processing logic  128  may then combine at least a portion of the data from one of the sensors with at least a portion of the data from the other sensor, e.g., comparing the data from the two sensors. For example, deriving an identity of color and orientation from the bracketing imagery aspect data of two cubes  122  from digital video camera  106  and sensor  114 .  
      Exemplary digital video cameras  102  and/or  106  may also be capable of detecting and/or recording and/or transmitting video/audio input as one or more data streams representing the video/audio information. Exemplary users  104  and/or  110  and/or another person and/or entity such as user  130  may provide input to the digital video camera  102  and/or the processor  126  and/or the processing logic  128  to select at least a portion of a data stream representing the video/audio information for retention at high resolution (where retention at high resolution is as described herein), e.g., imagery such as an image of a particular object and/or an audio aspect such as an instance of a particular voice and/or an instance of a particular sound. With respect to this example, digital video cameras  102  and/or  106  are representative of any sensor or sensor suite capable of detecting and/or recording and/or transmitting video/audio input as one or more data streams representing the video/audio information.  
      Those skilled in the art will appreciate that the explicitly described examples involving the exemplary sensors (the digital video camera  102 , the digital video camera  106 , the digital still camera  108 , and the sensor suite  112  including sensor  114  and sensor  116 ), the exemplary users (users  104 ,  110 , and  118 ), the exemplary objects (the sphere  120  and the cube  122 ), the network  124 , the exemplary processor  126 , and the exemplary processing logic  128  constitute only a few of the aspects illustrated by  FIG. 1 .  
      Following are a series of flowcharts depicting implementations of processes. For ease of understanding, the flowcharts are organized such that the initial flowcharts present implementations via an overall “big picture” viewpoint and thereafter the following flowcharts present alternate implementations and/or expansions of the “big picture” flowcharts as either sub-steps or additional steps building on one or more earlier-presented flowcharts. Those having skill in the art will appreciate that the style of presentation utilized herein (e.g., beginning with a presentation of a flowchart(s) presenting an overall view and thereafter providing additions to and/or further details in subsequent flowcharts) generally allows for a rapid and easy understanding of the various process implementations. In addition, those skilled in the art will further appreciate that the style of presentation used herein also lends itself well to modular and/or object-oriented program design paradigms.

For example, operation  1606  may include accepting input, via the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128 , to remove a first digital file including a retained portion of a video/audio stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices, when an examination of another set of retained data, such as an off-line library of archived video/imagery/audio records of persons and vehicles, indicates that an archived file at the size of the first digital file exists and is accessible to the user, such as user  130 , if such an archived file is required.  
       FIG. 17  shows a high-level logic flowchart of an operational process. The depicted operational process may include one or more of the following operations:  1700 ,  1702 ,  1704 ,  1706 ,  1708 ,  1710 , and/or  1712 .  
      Operation  1700  depicts accepting input to retain the portion of the data stream in a third digital file if a further retention condition is met, wherein the third digital file is smaller than the second digital file. Operation  1700  may include, for example, accepting input, via the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128 , to retain a portion of a video/audio data stream in a third digital file stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices, where the portion has been stored in a second digital file and the third digital file is smaller than the second digital file, if a further retention condition is met, such as the passage of a predetermined period of time from the retention of the portion in the second digital file with no accesses of the second digital file.  
      Operation  1702  shows accepting input to remove the second digital file if a further removal condition is met. Operation  1702  may include, for example, accepting input, via the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128 , to remove a second digital file including a retained portion of a video/audio stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices, if a further removal condition is met, such as a verification that a third digital file including at least a portion of the data included in the second digital file has been retained.  
      Operation  1704  depicts retaining the portion of a data stream in the first digital file. For example, operation  1704  may include retaining a portion of a video/audio data stream in a first digital file stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices.  
      Operation  1706  shows retaining the portion of the data stream in the second digital file if the retention condition is met. Operation  1706  may include, for example, retaining a portion of a video/audio data stream in a second digital file stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices, if a retention condition is met, such as a predetermined temporal distance range including a distance in the video/audio data stream between the portion and another portion designated for high-resolution retention.  
      Operation  1708  shows removing the first digital file if the removal condition is met. For example, operation  1708  may include removing a first digital file including a portion of a video/audio data stream and stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices if a removal condition is met, such as an absence of a predetermined amount of storage space, such as 3.0 GB.  
      Operation  1710  illustrates retaining the portion of the data stream in a third digital file if the further retention condition is met. For example, operation  1710  may include retaining a portion of a video/audio data stream in a second digital file stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices, if a further retention condition is met, such as the passage of a preselected period of time between the retention of the portion in second digital file larger than the third digital file without any accesses by a user such as user  130 .  
      Operation  1712  illustrates removing the second digital file if the further removal condition is met. Operation  1712  may include, for example removing a second digital file including a portion of a video/audio data stream and stored on the digital video camera  102  and/or the digital video camera  106  and/or the sensor  114  and/or the sensor  116  and/or the processor  126  and/or processing logic  128  and/or on some storage unit operably coupled to one or more of those devices if a removal condition is met, such as an absence of a predetermined amount of storage space, such as 3.0 GB.  
      Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.  
      The foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or examples. Insofar as such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof. In one embodiment, several portions of the subject matter described herein may be implemented via Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), digital signal processors (DSPs), or other integrated formats. However, those skilled in the art will recognize that some aspects of the embodiments disclosed herein, in whole or in part, can be equivalently implemented in integrated circuits, as one or more computer programs running on one or more computers (e.g., as one or more programs running on one or more computer systems), as one or more programs running on one or more processors (e.g., as one or more programs running on one or more microprocessors), as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and or firmware would be well within the skill of one of skill in the art in light of this disclosure. In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies equally regardless of the particular type of signal bearing media used to actually carry out the distribution. Examples of a signal bearing media include, but are not limited to, the following: recordable type media such as floppy disks, hard disk drives, CD ROMs, digital tape, and computer memory; and transmission type media such as digital and analog communication links using TDM or IP based communication links (e.g., packet links).  
      In a general sense, those skilled in the art will recognize that the various aspects described herein which can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or any combination thereof can be viewed as being composed of various types of “electrical circuitry.” Consequently, as used herein “electrical circuitry” includes, but is not limited to, electrical circuitry having at least one discrete electrical circuit, electrical circuitry having at least one integrated circuit, electrical circuitry having at least one application specific integrated circuit, electrical circuitry forming a general purpose computing device configured by a computer program (e.g., a general purpose computer configured by a computer program which at least partially carries out processes and/or devices described herein, or a microprocessor configured by a computer program which at least partially carries out processes and/or devices described herein), electrical circuitry forming a memory device (e.g., forms of random access memory), and/or electrical circuitry forming a communications device (e.g., a modem, communications switch, or optical-electrical equipment).  
      Those skilled in the art will recognize that it is common within the art to describe devices and/or processes in the fashion set forth herein, and thereafter use engineering practices to integrate such described devices and/or processes into image processing systems. That is, at least a portion of the devices and/or processes described herein can be integrated into an image processing system via a reasonable amount of experimentation. Those having skill in the art will recognize that a typical image processing system generally includes one or more of a system unit housing, a video display device, a memory such as volatile and non-volatile memory, processors such as microprocessors and digital signal processors, computational entities such as operating systems, drivers, and applications programs, one or more interaction devices, such as a touch pad or screen, control systems including feedback loops and control motors (e.g., feedback for sensing lens position and/or velocity; control motors for moving/distorting lenses to give desired focuses. A typical image processing system may be implemented utilizing any suitable commercially available components, such as those typically found in digital still systems and/or digital motion systems.

      All of the above U.S. patents, U.S. patent application publications, U.S. patent applications, foreign patents, foreign patent applications and non-patent publications referred to in this specification and/or listed in any Application Data Sheet, are incorporated herein by reference, in their entireties.  
      The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.  
      While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
