Dual aperture zoom camera with video support and switching / non-switching dynamic control

A zoom digital camera, comprising:

• a first imaging section that includes a first fixed effective focal length (EFL1) lens with a first field of view (FOV1) and a first sensor, the first imaging section operative to provide first image data of an object or scene;
• a second imaging section that includes a second fixed effective focal length (EFL2) lens with a second field of view (FOV2) that is narrower than FOV1 and a second sensor, the second imaging section operative to provide second image data of the object or scene;
• and
• a camera controller operatively coupled to the first and second imaging sections and configured to evaluate if a no-switching criterion is fulfilled or not fulfilled, wherein if the no-switching criterion is fulfilled in a zoom-in operation between a lower zoom factor (ZF) value and a higher ZF value at a zoom factor (ZF) higher than an up-transfer ZF, the camera controller is further configured to output a zoom video output image that includes only first image data, wherein if the no-switching criterion is not fulfilled, the camera controller is further configured to output a zoom video output image that includes only transformed, digitally zoomed second image data, and wherein EFL2>1.5×EFL1.
