Dual aperture zoom camera with video support and switching / non-switching dynamic control
A dual-aperture zoom digital camera operable in both still and video modes. The camera includes Wide and Tele imaging sections with respective lens/sensor combinations and image signal processors and a camera controller operatively coupled to the Wide and Tele imaging sections. The Wide and Tele imaging sections provide respective image data. The controller is configured to output, in a zoom-in operation between a lower zoom factor (ZF) value and a higher ZF value, a zoom video output image that includes only Wide image data or only Tele image data, depending on whether a no-switching criterion is fulfilled or not.
1. A camera controller operatively coupled to a Wide camera imaging section that provides Wide image data, and to a zoom Tele camera imaging section that provides Tele image data,
wherein the camera controller is configured to evaluate if a no-switching criterion is fulfilled or not fulfilled,
wherein if the no-switching criterion is fulfilled at a zoom factor value (ZF) higher than an up-transfer ZF, then the camera controller is further configured to output a zoom video image that includes only Wide image data,
or if the no-switching criterion is not fulfilled, then the camera controller is further configured to output at the same ZF higher than the up-transfer ZF a zoom video output image that includes only transformed, digitally zoomed Tele image data.
2. The camera controller of claim 1 , further comprising a user control module for receiving user inputs and a sensor control module for configuring a Wide camera image sensor and a Tele camera image sensor to acquire the Wide and Tele image data based on the user inputs.
3. The camera controller of claim 1 , wherein the camera controller is further configured to combine in still mode, at a predefined range of ZF values, at least some of the Wide and Tele image data to provide a fused output image of an object or scene from a particular point of view.
4. The camera controller of claim 2 , wherein the camera controller is further configured to combine in still mode, at a predefined range of ZF values, at least some of the Wide and Tele image data to provide a fused output image of an object or scene from a particular point of view.
5. The camera controller of claim 1 , wherein the camera controller is configured to register Tele image pixels to a matching pixel set within Wide image pixels to obtain a fused image and wherein the point of view is a point of view of a Wide camera.
6. The camera controller of claim 2 , wherein the camera controller is configured to register Tele image pixels to a matching pixel set within Wide image pixels to obtain a fused image and wherein the point of view is a point of view of a Wide camera.
7. The camera controller of claim 3 , wherein the camera controller is configured to register Tele image pixels to a matching pixel set within Wide image pixels to obtain the fused image and wherein the point of view is a point of view of a Wide camera.
8. The camera controller of claim 4 , wherein the camera controller is configured to register Tele image pixels to a matching pixel set within Wide image pixels to obtain the fused image and wherein the point of view is a point of view of a Wide camera.
