Refer toCh. 8 – Viewing, Editing, and Annotating Images for details on viewing and modifying image sequencefilesImage Captures in Other ProceduresIn addition to the basic image captures, the Camera menu contains options in which one image capture isused to prepare the camera for the final image capture They include:• Set Chip Imaging Area• Set Spot Metering Area• Compute Exposure• Recall Previous Exposure• Compute White Balance Values• Get Bias Frame• Get Thermal Frame• Get Flatfield ImageInsightB/WInsight B/W camera users will not see Compute White Balance Values option (or the corresponding toolbarbutton).Because they are used prior to a final image capture, several of these options are discussed as a part of theimage setup process. In such cases, the text of the manual refers back to the appropriate section of Chapter5 - Preparing to Take a Picture.Set Chip Imaging AreaThe Set Chip Imaging Area selects a specific portion of the CCD chip. This option is available once animage has been captured. Using just a small portion of the available area on the CCD chip is usefulbecause:• The download time will be shorter.• The file size will be smaller and easier to manage.To avoid confusion when defining the region of the image that you want to capture, it is important torealize that there are two separate coordinate systems in use:• The coordinate system of the CCD chip• The coordinate system of the displayed imageThe coordinates displayed on the Status Bar as the cursor is moved over a displayed image are always“displayed image” coordinates. The coordinates displayed in the Set Chip Imaging Area dialog box arealways CCD chip coordinates. These coordinate systems match only if the orientation of an image has notchanged (i.e., it has not been flipped or rotated).Because the SPOT software tracks orientation changes, you can select a Chip Imaging Area on anydisplayed image, regardless of whether the orientation has changed: the Set Chip Imaging Area dialog boxwill correctly display the region of the CCD chip that you designated as the imaging region. However,because of the different coordinate systems, the coordinates that you see on the Status Bar (i.e., whenmoving the cursor over the displayed image) may not match the coordinates that appear in the Set ChipImaging Area dialog box if the image was flipped or rotated.User Guide to the SPOT Insight Camera 127
