The time-of-flight ranging sensor 154 is disposed on the portion of the first flexible circuit board 152. In some embodiments, the time-of-flight ranging sensor 154 includes a light transmitter (not shown) and a light receiver (not shown). In some embodiments, the time-of-flight ranging sensor 154 also includes a packaging structure of the light transmitter and the light receiver. In some embodiments, as Figure 1 and Figure 2 As shown, the TOF module 150 further includes a filter 156, which is adjacent to the TOF sensor 154 and is disposed in the opening 130a of the rotating member 130. The filter 156 is configured to allow light of a specific wavelength range to pass through the filter 156 and then reach the light receiver of the TOF sensor 154.

[0056] Figure 5 FIG. 4 is a top view of a sensing array of a time-of-flight ranging sensor according to an embodiment of the present invention. Figure 5 As shown, the TOF sensor 154 has a sensing array 1542, and the sensing array 1542 has a plurality of sensing points (not shown) arranged in an array. In some embodiments, the sensing array 1542 is arranged in a non-circular and non-regular polygonal area (which corresponds to the imaging screen of the lens module 124), for example, in a rectangular area, but the present invention is not limited thereto. When the rotating member 130 is rotated, the camera module 120 and the TOF module 150 (including the sensing array 1542 of the TOF sensor 154) also rotate, so that the distribution area of ​​the sensing array 1542 still corresponds to the imaging screen of the lens module 124.

[0057] In some embodiments, Figures 2 to 4 As shown, the image capture device further includes a switching module 160. The switching module 160 includes a switching board 162 and a circuit 164. The switching board 162 is disposed in the housing 110 and is close to the back of the lens module 124. In some embodiments, Figure 4 As shown, the first flexible circuit board 152 of the time-of-flight ranging module 150 is connected to the adapter board 162. In some embodiments, the first flexible circuit board 152 is connected to the back side of the adapter board 162. In some embodiments, as Figure 3 and Figure 4 As shown, one end of the first flexible circuit board 152 is fixed to the lens module bracket 122, and the other end is fixed to the adapter board 162. One end of the line 164 is connected to the back of the adapter board 162. The first flexible circuit board 152 is electrically connected to the line 164 through the adapter board 162. In some embodiments, Figures 2 to 4As shown, the lens module 124 further includes a second flexible circuit board 1244, which is connected to the adapter board 162. In some embodiments, the second flexible circuit board 1244 is connected to the back of the adapter board 162.

In some embodiments, the image capture device further includes a main board (not shown), and the other end of the line 164 is connected to the main board; in other words, the line 164 is electrically connected between the adapter board 162 and the main board. In this way, the distance data of the object sensed by the time-of-flight ranging sensor 154 of the time-of-flight ranging module 150 can be sequentially transmitted to the processor (such as a SOC processor) of the main board through the first flexible circuit board 152, the adapter board 162 and the line 164 for calculation, and the calculated signal is then sequentially transmitted to the second flexible circuit board 1244 through the line 164 and the adapter board 162 to control the lens module 124 to perform fast focusing.

[0058] In some embodiments, Figures 2 to 4 As shown, the adapter module 160 further includes a line bracket 166, which is adjacent to the back side of the adapter plate 162. Figure 4 As shown, the line bracket 166 has a central opening 166c, and the line 164 passes through the central opening 166c. When the rotating member 130 is rotated, the adapter plate 162 and the line 164 fixed on the back thereof will rotate. In some embodiments, the line bracket 166 is configured to prevent the line 164 from being hooked into a nearby groove or being pulled when the line 164 rotates.

[0059] In some embodiments, Figure 4 As shown, the line support 166 also has a strip opening 166s, which is connected to the central opening 166c. In some embodiments, when the line support 166 needs to be moved away from the adapter plate 162 (for example, during reprocessing or maintenance), the operator can rotate the line support 166 so that a portion of the line 166s close to the line support 166 overlaps or substantially overlaps with the strip opening 166s, so that the operator can easily lift up the line support 166 and move it away from the adapter plate 162.

[0060] In some embodiments, Figure 2 As shown, the image capture device further includes a heat sink 170, which is disposed between the second flexible printed circuit board 1244 and the adapter board 162. The heat sink 170 is configured to help components nearby to dissipate heat, so that the image capture device can operate for a long time.
