Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic flowchart illustrating a control method of an image pickup apparatus according to an embodiment of the present disclosure. The display control method shown in the embodiments of the present disclosure may be applied to an image capturing device, which may be independent, such as a camera, a video recorder, or the like, or may be integrated with other devices, such as a camera of a camera.
Since the photoelectric conversion elements generally store the generated charges through corresponding capacitors, when the brightness of light received by a part of the photoelectric conversion elements in the array of the photoelectric conversion elements is too high, the amount of generated charges exceeds the upper storage limit of the capacitors, for example, the generated charges is greater than a preset charge amount, such a photoelectric conversion element belongs to an overexposed photoelectric conversion element, and may be referred to as a first photoelectric conversion element, the excess charges are transferred to a second photoelectric conversion element which is closer to the first photoelectric conversion element, for example, less than the preset distance, and the generated charges are less than or equal to the preset charge amount. Wherein, predetermine electric quantity and predetermine the distance and can confirm according to actual conditions.
This causes a larger amount of electric charge to be stored in the capacitor corresponding to the second photoelectric conversion element than is actually generated by the second photoelectric conversion element, which is generally located around the first photoelectric conversion element, so that a ring of areas with higher luminance is formed around the area corresponding to the first photoelectric conversion element in an image, causing a glare problem.
As shown in fig. 1, a control method of an image capturing apparatus according to an embodiment of the present disclosure may include:
in step S1, detecting an amount of power generated by the photoelectric conversion elements in the photoelectric conversion element array, and determining a first photoelectric conversion element in which the generated amount of power is greater than a preset amount of power;
in step S2, a glare area having a luminance greater than an actual luminance due to the amount of electricity generated by the first photoelectric conversion element being greater than a preset amount of electricity is determined in the image;
in step S3, the brightness of the glare area is reduced when an image is generated.
According to the embodiment of the disclosure, the first photoelectric conversion element which is overexposed in the photoelectric conversion element array can be determined, the glare area with the brightness larger than the actual brightness caused by the fact that the electric quantity generated by the first photoelectric conversion element is larger than the preset electric quantity in the image is determined, and then when the image is generated, the brightness of the glare area is pertinently reduced, so that the problem caused by overexposure of the first photoelectric conversion element can be overcome, other areas without the glare problem in the image cannot be influenced, the brightness of other areas is prevented from being reduced and is not consistent with the actual brightness, and details are favorably displayed.
It should be noted that, in the embodiments of the present disclosure, the detection of the electric quantity generated by the photoelectric conversion element in the photoelectric conversion element array may be the detection of the electric quantity generated by the photoelectric conversion element in the photoelectric conversion element array during shooting of one frame of image, or the detection of the electric quantity generated by the photoelectric conversion element in the photoelectric conversion element array during shooting of multiple frames of images. The operation of reducing the brightness of the glare area may be performed on the current frame image after the glare area is determined, and/or on the next frame or frames of images.
Fig. 2 is a schematic flowchart illustrating another control method of an image pickup apparatus according to an embodiment of the present disclosure. As shown in fig. 2, on the basis of the embodiment shown in fig. 1, the reducing the brightness of the glare area includes:
in step S31, the photoelectric conversion rate of the first photoelectric conversion element is decreased.
In one embodiment, the photoelectric conversion rate of the first photoelectric conversion element can be reduced, and accordingly, when the first photoelectric conversion element receives light rays with the same brightness, the generated charges are reduced, so that the situation that the capacitance corresponding to the first photoelectric conversion element reaches the storage upper limit and the stored charges in the capacitance do not reach the storage upper limit is avoided, the charges in the capacitance cannot be transmitted to the second photoelectric conversion element near the first photoelectric conversion element, and the glare problem cannot occur.
Even if the capacitance corresponding to the first photoelectric conversion element reaches the storage upper limit, the charges generated continuously by the first photoelectric conversion element can be reduced, and further the charge quantity transmitted to the second photoelectric conversion element near the first photoelectric conversion element by the capacitance is reduced, so that the glare phenomenon around the corresponding area of the first photoelectric conversion element in the image is relieved.
In one embodiment, the storage upper limit of the capacitance corresponding to each photoelectric conversion element in the photoelectric conversion element array is ideally the same, and when an excessively strong light is irradiated on the first region of the photoelectric conversion element array, which causes a glare phenomenon in the first region around the corresponding region in the image, the capacitances corresponding to the first photoelectric conversion elements in the first region all reach the storage upper limit, and the brightness of the corresponding region in the image is the same.
The intensity of the light irradiated on the first region generally decreases from the central point to the outside, and for the first photoelectric conversion element generating the electric quantity greater than the preset electric quantity, that is, the first photoelectric conversion element at the central point generates the most electric quantity, and the first photoelectric conversion element further to the outside generates the less electric quantity.
If the reduction amplitudes of the photoelectric conversion rates for all the first photoelectric conversion elements are the same, the electric quantity generated by the inner first photoelectric conversion element may still fill the corresponding capacitor, while the electric quantity generated by the outer first photoelectric conversion element may not fill the corresponding capacitor, so that the brightness of the corresponding area of the outer first photoelectric conversion element in the image is lower than the brightness of the corresponding area of the inner first photoelectric conversion element in the image, and thus the brightness of the area of the image where the brightness is the same is different.
When the photoelectric conversion rate of the first photoelectric conversion element is reduced, for the first photoelectric conversion elements at different positions, the reduced photoelectric conversion rate may be reduced by different proportions, for example, the reduced photoelectric conversion rate of the first photoelectric conversion element at the outer side is less than that of the first photoelectric conversion element at the inner side, so as to ensure that the brightness of the area, which should have the same brightness, in the image is still the same after the reduction of the photoelectric conversion rate.
Fig. 3 is a schematic flowchart illustrating a control method of still another image pickup apparatus according to an embodiment of the present disclosure. As shown in fig. 3, on the basis of the embodiment shown in fig. 1, the reducing the brightness of the glare area includes:
in step S32, when a time period during which the first photoelectric conversion element outputs a current to the capacitor corresponding to the first photoelectric conversion element reaches a first preset time period, the output of the current to the capacitor corresponding to the first photoelectric conversion element by the first photoelectric conversion element is interrupted. The first preset duration can be set according to needs.
In an embodiment, when a duration of a current output from the first photoelectric conversion element to the capacitor corresponding to the first photoelectric conversion element reaches a first preset duration, the current output from the first photoelectric conversion element to the capacitor corresponding to the first photoelectric conversion element is interrupted, so that a process of the capacitor corresponding to the first photoelectric conversion element receiving the charge transmitted by the first photoelectric conversion element does not exceed the first preset duration, which is beneficial to preventing the capacitor used for storing the charge generated by the first photoelectric conversion element in the first photoelectric conversion element from reaching an upper storage limit, and the capacitor stored charge does not reach the upper storage limit, so that the charge in the capacitor is not transmitted to the second photoelectric conversion element near the first photoelectric conversion element, and a glare problem does not occur.
Even if the capacitance corresponding to the first photoelectric conversion element reaches the storage upper limit, the charge quantity continuously stored by the capacitance can be reduced, and further the charge quantity transmitted to the second photoelectric conversion element nearby the first photoelectric conversion element by the capacitance is reduced, so that the glare phenomenon around the corresponding area of the first photoelectric conversion element in the image is relieved.
Fig. 4 is a schematic flowchart illustrating a control method of still another image pickup apparatus according to an embodiment of the present disclosure. As shown in fig. 4, based on the embodiment shown in fig. 1, the reducing of the brightness of the glare area:
in step S33, when a period of time in which the first photoelectric conversion element outputs a current through photoelectric conversion reaches a second preset period of time, interrupting electrical connection between the first photoelectric conversion element and the second photoelectric conversion element;
the second photoelectric conversion element is a photoelectric conversion element which is in the photoelectric conversion element array and is away from the first photoelectric conversion element, and the generated electric quantity is smaller than or equal to the preset electric quantity. The second preset duration may be set as desired.
In one embodiment, for the second photoelectric conversion element, an excess charge generated by the first photoelectric conversion element is transferred to the second photoelectric conversion element, and for this purpose, when a duration of the output current of the first photoelectric conversion element through photoelectric conversion reaches a second preset duration, the electrical connection between the first photoelectric conversion element and the second photoelectric conversion element is interrupted, so that even if a capacitance corresponding to the first photoelectric conversion element reaches an upper storage limit, the excess charge transferred to the capacitance by the first photoelectric conversion element is not transferred to the second photoelectric conversion element, thereby avoiding a glare phenomenon around a corresponding area of the first photoelectric conversion element in an image.
