Canon is working on the development of a process that is designed to facilitate the correct adjustment of tilt-shift lenses to control the depth and depth of the depth of field. In the Live View mode, Canon uses variable grid lines on the LCD monitor or in the electronic viewfinder, which can be used to specify the desired range of focus. This is the result of a patent application published by the Japanese Egami blog in early May.
Next step Electronic Perspective Correction?
However, new TS lenses, which provide the camera with corresponding information about the adjustment as well as new cameras, can process the corresponding information. However, the values for the adjustment determined by such camera lens combinations for certain motif conditions would have to be adjusted manually on the lens. A motorized tilt-shift lens, as would be necessary for an automatic setting according to the camera prescription, appears to be hardly realizable.
Unlike the variation of the depth of focus, which can not be influenced electronically in normal cameras, a perspective correction of falling lines by the camera's image processor is likely to be more electronically possible than by mechanical lens adjustment. A touchscreen monitor would make it easy to make a predefined preset by simply dragging straight lines through the touchscreen.

The higher the pixel number of a camera, the greater the reserves for such an electronic solution. One of their advantages would be that, right from the beginning of the recording, and not later in the image processing on the computer, one sees which image areas are cut off in the perspective correction so that the image section can be extended as far as necessary.
