Claims (5)

An imaging device having a plurality of pixels that convert an optical image formed on the imaging surface into a video signal, a focus lens that forms the optical image on the imaging surface, and the focus for adjusting the focus of the optical image and focusing means for moving the lens, Bei example an electronic zoom means for performing an electronic zoom to the optical image,
The focus means moves the focus lens by a first movement amount when the magnification of the electronic zoom performed by the electronic zoom means is the first magnification, and the magnification of the electronic zoom is changed to the first magnification. An electronic camera , wherein the focus lens is moved by a second movement amount larger than the first movement amount in the case of a second variable magnification smaller than the magnification .   2. The electronic camera according to claim 1, wherein the focusing unit increases the amount of movement of the focus lens when a predetermined zoom ratio of the electronic zoom performed by the electronic zoom unit is less than one.   2. The focus unit according to claim 1, wherein when the predetermined zoom ratio of the electronic zoom performed by the electronic zoom unit is less than 1, the focus unit moves the focus lens to a position deviated from the in-focus position. Electronic camera.   4. The electronic camera according to claim 2, wherein the electronic zoom means performs the electronic zoom in a state where the resolution of the image sensor is reduced.   5. The electronic camera according to claim 4, wherein the electronic zoom means reduces the resolution of the image sensor by thinning out the plurality of pixels.
