Image capture with adjustment of imaging properties at transitions between regions

摘要

Image capture by using an imaging assembly having spectral sensitivities which are tunable in accordance with a capture parameter. First and second capture parameters are applied respectively to first and second regions of a scene, and a preview image is captured and displayed, together with a user interface which permits a user to adjust a transition of the capture parameter at a boundary between the first and second regions. Further preview images may be captured and displayed until the user is satisfied with the appearance of the preview image at the boundary of the first and second regions. A final image is captured using the first and second capture parameters together with any adjustment to the transition of the capture parameters at the boundary between the first and second regions.

1. An apparatus comprising:
an imaging assembly for capturing an image of a scene, wherein areas of the imaging assembly have respective spectral sensitivities which are tunable in terms of intensity and color in accordance with respective capture parameters; and a display screen for displaying a user interface, wherein a user selects multiple regions of interest of the scene including a first region and a second region, wherein for each selected region of interest, a capture parameter corresponding to the region of interest of the scene is selected, including a first capture parameter and a second capture parameter, wherein the display screen is further constructed to display a user interface to adjust capture parameter transitions between the selected regions of interest by (a) adjusting respective values of capture parameters of areas of the tunable imaging assembly corresponding to a boundary, (b) accepting and determining respective points of interest within the selected regions of interest, (c) changing a transition of the capture parameter by adjusting a curve between the points of interest by adjusting intermediate points between the points of interest and without adjusting the values of the capture parameter for the points of interest, (d) revising the capture parameters based on the capture parameter adjusted and the transition of the capture parameter adjusted, (e) calculating spatial mask values to be applied to the tunable imaging assembly based on the revised capture parameters, and wherein in a case that a target imaging property is a target range for brightness, the capture parameter is revised by computing a brightness change parameter based on a comparison of original brightness values in the image with the target range of brightness for the selected regions and an adjusted transition of a brightness value at a boundary between regions, and combining the brightness change parameter with the capture parameter.
