We all know Canon is now busy making next-generation vlogging cameras. And their R&D team working with the DPAF technique to introduce an AI blur function inside the camera. So, once you will push the AI Blur button the Camera will automatically set your lens to its Max aperture, and then with the help of DPAF pixels advance AI algorithms (BLRrmax) the camera will allow users to fine-tune the type of bokeh or introduce more blur.
Although the Patent is very NEW, So we can expect such a feature in the Canon camera sometime in 2023 or later.

To provide an imaging apparatus that suppresses an overlap of a blur with respect to an in-focus region when imaging for a composite image of depth composition while maintaining a sense of resolution.SOLUTION: The imaging apparatus (digital camera 100) has an imaging unit 22 that captures a plurality of images captured with angles of view at least parts of which are overlapped with subjects and at different focal positions, a system control unit 50 that acquires distance information of the subjects and acquires a difference in distances based on the distance information to set a diaphragm value based on the difference in distances, and an image processing unit 24 that synthesizes a plurality of images. The imaging unit 22 captures a plurality of images with the diaphragm value set by the system control unit 50.SELECTED DRAWING: Figure 2
The image processing unit 24 calculates some blurring rates by performing the above calculation on all adjacent regions (for example, regions 511 and 513 in FIG. 5, and regions 512 and 513).
In step S405, the image processing unit 24 sets the maximum blur rate calculated in step S404 as the maximum blur rate.
Next, in step S305, the system control unit 50 determines the aperture value based on the allowable blur amount.
The allowable blur amount referred to here may be preset depending on the properties of the lens or the like, or may be set by the user.
Next, in step S305, the system control unit 50 determines the aperture value based on the allowable blur amount.
The allowable blur amount referred to here may be preset depending on the properties of the lens or the like, or may be set by the user.
First, the amount of blur d on the imaging unit 22 can be calculated by the following (Equation 5).
However, D represents the effective aperture, and BLRrmax represents the maximum blur rate estimated in step S304.
