All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The imaging device provided by the embodiment comprises at least two lenses, a light through hole, an image sensor and a controller.
The lens is used for capturing light generated by a shot object, guiding the propagation direction of the entering light and converging the entering light to a photosensitive surface of the image sensor. In practice, the lens assembly is composed of optical lenses and/or other optical elements, and the lenses used may be spherical lenses or aspherical lenses, which are within the protection scope of the present invention. The number of the lenses is not limited in this embodiment, and is set according to the actual application requirements in specific implementation.
The lenses are provided with diaphragms with different sizes respectively, and the lenses are provided with different light transmission amount ranges respectively. The lens has a small-sized diaphragm, the light flux amount of the small-sized diaphragm is small, and light passing through the lens is small during shooting; the lens has a large-sized diaphragm, and the light passing amount is large, so that the light passing through the lens is large during shooting.
The light through hole is correspondingly arranged at one end of the lens facing the image sensor, and the selection of which lens is used for framing shooting is controlled by controlling the opening or closing of the light through hole.
In this embodiment, the arrangement and position of each lens are not limited, and the distance between the lenses is preferably as small as possible to ensure the consistency of the captured images. Optionally, at least two lenses may be arranged in sequence, and the plurality of light passing holes are arranged in sequence corresponding to the respective lenses. Referring to fig. 1, the image pickup apparatus shown in fig. 1 is illustrated as an image pickup apparatus including two lenses, wherein the image pickup apparatus includes a first lens 10 and a second lens 11 arranged in sequence, and light passing holes 12 provided in one-to-one correspondence with the respective lenses.
The image sensor is used for receiving light generated by a shot object, entering the lens and passing through the lens, and forming an image of the shot object through photoelectric conversion. The image sensor forms an image based on a photoelectric imaging principle, and can perform image processing to finally obtain a shot image.
In specific implementation, the image sensor may adopt a CCD element array, a CMOS element array or an APD (avalanche photo diode) element array, and the configuration thereof may be in the form of a linear detector, an area detector or a single-point detector. It will be appreciated that other types of photo-imaging devices may be used.
Preferably, referring to fig. 1, the present imaging apparatus employs one image sensor 13, and each lens faces the same image sensor 13, so as to ensure consistency of the captured images.
In the camera device, the controller is used for sensing the intensity of the external light, controlling the light through hole corresponding to one lens with the corresponding size aperture to be opened according to the intensity of the external light, and controlling the light through holes corresponding to other lenses to be closed so that the image sensor receives the light passing through the corresponding lens to form an image of a shot object.
In specific implementation, referring to fig. 1, the controller includes a photosensitive element 14 for sensing the intensity of the external light, the photosensitive element is an optical element whose at least one parameter value changes with the illumination intensity, and the intensity of the external light is sensed by using the characteristic of the photosensitive element. In practice, the light sensor 14 may be a light sensor, or other types of light sensors may be used, and are within the scope of the present invention.
Next, a mode in which the controller controls the lens to be selected according to the intensity of the external light in the imaging apparatus will be described.
Specifically, the controller is specifically configured to control the light through hole corresponding to the lens with the aperture of the corresponding size to be opened according to the intensity of the external light, and the size of the aperture of the selected lens is in negative correlation with the intensity of the external light. When the controller selects the lens according to the intensity of the external light, if the intensity of the external light is large, the lens with the small-size aperture is selected, and the corresponding light through hole is controlled to be opened; if the external light intensity is small, a lens with a large-size aperture is selected, and the corresponding light through hole is controlled to be opened. In specific implementation, a corresponding control algorithm can be formed in the controller through programming, a relational expression of the aperture size of the selected lens and the external light intensity is established, and the controller selects the lens according to the current sensed external light intensity according to the relational expression and the control algorithm.
In particular, the controller may be a CPU chip.

Therefore, when the external light intensity is high, the lens with the small-size aperture is selected for shooting, the light transmission amount of the lens is small, light passing through the lens is small, the phenomenon that a shot image is too bright is avoided, and the image effect is ensured; when the external light intensity is small, a lens with a large-size aperture is selected for shooting, the light passing amount of the lens is large, light rays passing through the lens are large, the situation that a shot image is fuzzy is avoided, and the image effect is guaranteed.
Correspondingly, the embodiment of the invention also provides electronic equipment which comprises the camera device.
