An autofocus apparatus sets a portion of an image frame as an AF area. Then, in first image-pickup, acquires first image data for the AF area within the image frame according to a first light flux from an object passing through an aperture of the diaphragm when the diaphragm is not shifted. Further,

An autofocus apparatus sets a portion of an image frame as an AF area. Then, in first image-pickup, acquires first image data for the AF area within the image frame according to a first light flux from an object passing through an aperture of the diaphragm when the diaphragm is not shifted. Further, in second image-pickup, acquires second image data for the AF area within the image frame according to a second light flux from the object passing through the aperture of the diaphragm when the diaphragm is shifted in one vertical direction with respect to the optical axis. A cross correlation between the first image data and the second image data is computed, and a distance up to a focus position of the focal lens as well as a direction thereof is computed according to the cross correlation. Then, the focal lens is driven to the focus position.

The method of claim 1, further comprising defining a second view that specifies how data collected by the first component is to be displayed, wherein the navigation interface provides an option for users to select between at least the first and second views to view data collected by an instance of the first component. 3. The method of claim 1, wherein the first component is configured to collect data describing a status of at least one element of machinery within a manufacturing facility. 4. The method of claim 1, wherein the first component is configured to collect real-time data from back-end data sources. 5. The method of claim 4, wherein the first component is further configured to collect non-real-time data from at least one back-end database. 6. The method of claim 1, wherein the first component represents a business unit that is replicated within the business entity. 7. The method of claim 6, wherein the first component is configured to collect data from a disparate set of back-end data sources that are associated with each such replicated business unit. 8. The method of claim 6, wherein the first component comprises a second component that represents a business sub-unit that exists within each replicated business unit, said second component being associated with a second view that specifies how data associated with the business sub-unit is displayed. 9. The method of claim 8, wherein the navigation interface represents each such business sub-unit within a navigation node structure as a child of the respective business unit to which that sub-unit corresponds. 10. The method of claim 1, wherein the first component comprises multiple members, and wherein the step of connecting the multiple instances of the first component to respective sets of back-end data sources comprises connecting each member of each instance of the first component to a different respective back-end data source. 11. The method of claim 1, wherein defining the first view comprises defining an animation, said animation providing an image that changes in appearance in response to fluctuations in data collected from a back-end data source. 12. The method of claim 1, wherein defining the first view comprises including within the first view a hyperlink to a second view that corresponds to a second component. 13. The method of claim 1, further comprising generating a second component that represents a second type of business element that exists within the business entity, wherein the second component contains the first component, and wherein the navigation interface permits a user to drill down from an instance of the second component to a corresponding instance of the first component to view data collected by the first component. 14.
