An image pickup apparatus and an electronic device according to an embodiment of the present application are described below with reference to fig. 1 to 4. The arrows in fig. 4 indicate the moving direction of the photo sensor chip module 106.

As shown in fig. 1 and 4, a first embodiment of the present application provides an image capturing apparatus, which includes a housing 102, a lens module 104, a photo-sensing chip module 106, a driving member 108, and a rolling member 122. The photo sensor chip module 106 is disposed in the housing 102, and the lens module 104 is mounted in the housing 102 and spaced apart from the photo sensor chip module 106; the driving member 108 includes a first driving portion 110 and a second driving portion 112, the first driving portion 110 is disposed on the housing 102, the second driving portion 112 is disposed on the photo sensor chip module 106, and the first driving portion 110 and the second driving portion 112 cooperate to drive the photo sensor chip module 106 to move, so as to change a distance between the photo sensor chip module 106 and the lens module 104; one of the photo sensor chip module 106 and the housing 102 is provided with a receiving groove, and the rolling member 122 is disposed inside the receiving groove and contacts with the other one of the photo sensor chip module 106 and the housing 102 to roll in the process of lifting the photo sensor chip module 106.

Particularly, for the image capturing apparatus, the weight of the photo sensor module 106 is much lower than that of the lens module 104, which makes the driving force required for driving the photo sensor module 106 to move in the embodiment of the present application small, and particularly compared with the design scheme of driving the lens module in the related art, the driving force of the driving member 108 can be significantly reduced, and the structure is simplified. Thus, as shown in fig. 4, in the case that the driving members 108 provide the same driving force, the embodiment of the present application can drive the photosensitive chip module 106 with a larger weight; under the condition that the driving member 108 provides the driving force with the same magnitude, the embodiment of the application can drive the photosensitive chip module 106 with the same weight for a longer distance, thereby improving the focusing range of the camera device.

In addition, as shown in fig. 1 and 4, the photo chip module 106 is disposed inside the housing 102 and has a certain distance from the lens module 104, which enables the embodiment of the present application to directly use the internal space of the housing 102 to drive the photo chip module 106 to move.
