Detailed Description

Embodiments of the present application are illustrated in the drawings and, for purposes of clarity, numerous implementation details are set forth in the following description. It should be understood, however, that these implementation details should not be used to limit the application. That is, in some embodiments of the present application, details of these implementations are not necessary.

As shown in the drawings, the present application provides an image pickup apparatus 1 that can be applied to an electronic apparatus such as a notebook, a tablet, or a home camera. After the electronic device of the present application sets a simple command through the internal system, it can control the light emitting component 15 in the camera device 1 to emit light, so that the photosensitive effect of the sensor 131 is saturated, thereby generating an overexposed image effect, and thus, the camera device 1 can not acquire a normal image.

In the present embodiment, the imaging device 1 includes a substrate 11, a camera 13, and a light emitting element 15. The camera 13 includes a sensor 131 and a lens assembly 133, the sensor 131 is disposed on the substrate 11, and the lens assembly 133 is disposed on the sensor 131. The light emitting assembly 15 is disposed at one side of the sensor 131, and the light emitting assembly 15 is used for emitting yellow light and transmitting the yellow light to the camera 13. When the sensor 131 senses yellow light emitted from the light emitting element 15, the image captured by the sensor 131 is overexposed. In the present embodiment, the wavelength range of the light generated by the light emitting element 15 is 577nm-595nm, the light in this range appears yellow to human eyes, and according to the relationship between the wavelength of the light and the saturation photocurrent, the saturation current required for the yellow light in this wavelength range is relatively small, and the number of emitted photoelectrons is small, so that the light emitting element 15 can saturate the sensor 131 with relatively small power, that is, the light emitting element 15 in the present embodiment can more efficiently achieve overexposure of the image captured by the sensor 131.

Furthermore, the lens assembly 133 further includes a lens holder 135 and a lens group 137, the lens holder 135 has a first accommodating portion 1351 and a second accommodating portion 1353, the first accommodating portion 1351 is communicated with the second accommodating portion 1353, the lens holder 135 is disposed on the base plate 11, the sensor 131 and the light emitting element 15 are disposed in the second accommodating portion 1353, the lens group 137 is mounted in the first accommodating portion 1351 and corresponds to the sensor 131, the lens group 137 has a first end 1371 and a second end 1373, and the first end 1371 of the lens group 137 is disposed toward the second accommodating portion 1353. The yellow light emitted from the light emitting element 15 is distributed in the second accommodating portion 1353 and enters the lens set 137 from the first end 1371 and exits from the second end 1373.

As mentioned above, the lens holder 135 includes a first side wall 1355, a top wall 1357 and a second side wall 1359, a bottom edge of the second side wall 1359 is connected to the base plate 11, a top edge of the second side wall 1359, which is remote from the base plate 11, is connected to an outer peripheral edge of the top wall 1357, an inner peripheral edge of the top wall 1357 is connected to a bottom edge of the first side wall 1355, the second side wall 1359 and the top wall 1357 together define a second receptacle 1353, and the first side wall 1355 defines a first receptacle 1351. The light emitting assembly 15 has a light emitting face 151, the light emitting face 151 facing the top wall 1357. The light emitting surface 151 of the light emitting element 15 emits light. When the light from the light emitting element 15 is reflected and dispersed by the top wall 1357 and the second side wall 1359, the second container portion 1353 is filled with light, a portion of the light is transmitted by the lens set 137, and a portion of the light is received by the sensor 131. Since the yellow light of the light emitting element 15 can improve the overexposure efficiency of the sensor 131, the image captured by the sensor 131 can be overexposed only by the light of the yellow light reflected and dispersed in the second accommodating portion 1353 without providing a corresponding light guide element for the light emitting element 15. In one embodiment, the inner surfaces of the top wall 1357 and the second side wall 1359 have a light reflection structure, so that the light is reflected by the light reflection structure and is focused to irradiate towards the sensor 131 and/or the first end 1371 of the lens group 137.

Please refer to fig. 5, which is a schematic diagram of a second embodiment of the present application. As shown in the figure, the light-emitting surface 151 of the light-emitting element 15 may also be disposed toward the sensor 131, that is, the light-emitting surface 151 of the light-emitting element 15 is disposed in a direction away from the second side wall 1359, so that the light of the light-emitting element 15 can be directly projected in the direction of the sensor 131 or/and the first end 1371 of the lens set 137, and the light is not irradiated by reflection, so that the intensity of the light is not reduced.

In addition, the camera 13 further includes an optical filter 139, and the optical filter 139 is disposed between the sensor 131 and the lens assembly 133. Wherein the filter 139 is located in the second receiving portion 1353 and is fixed to the top wall 1357.

Wherein the switch element 17 is a mosfet.

In the present embodiment, the user sets the internal system of GPIO (General Purpose Input Output) and uses the control signal as a means for automatically controlling the switch element 17. The control signal of the present embodiment is a high level signal, and the high level and the low level are used as a means for automatically controlling the switch element 17. When the control circuit 19 is in the high state, it turns on the switch element 17 to activate the light emitting element 15 to emit yellow light, which saturates the photosensitive effect of the sensor 131, so that the camera 13 cannot acquire normal images. On the contrary, when the control circuit 19 is in a low level state, the switch element 17 is not turned on, and the light emitting element 15 is not turned on, so that the camera 13 can be normally used.
