There is no possibility of the occurrence of an unnecessary event. An imaging device includes a photoelectric conversion section including a plurality of photoelectric conversion elements, each of the plurality of photoelectric conversion elements being configured to photoelectrically convert incoming light into an electrical signal, a first detection section that detect a detection signal in a case where an absolute value of an amount of change in the electrical signal generated by each of the plurality of photoelectric conversion elements exceeds a predetermined threshold, a flicker determination section that determines whether or not a detection signal caused by a flicker of a light source is included in the detection signals detected by the first detection section, and a second detection section that detects a detection signal caused by a factor other than the flicker, from among the detection signals detected by the first detection section, in a case where it is determined that the detection signal caused by the flicker is included.

An image capturing apparatus comprising an image capturing unit; a flicker detection unit; and a control unit configured to cause, in parallel, an execution of a first image capturing operation in which the image capturing unit is caused to periodically capture an image for storage and a second image capturing operation in which the image capturing unit is caused to periodically capture an image for display, wherein the control unit: in the first image capturing operation, causes the image capturing unit to perform capturing in accordance with a peak timing of a flicker; and in a case where an accumulation period in the first image capturing operation and an accumulation period in the second image capturing operation overlap, changes a timing of capturing in the second image capturing operation.

The present disclosure discloses an image flicker detection method that includes the steps outlined below. An image retrieving is performed to retrieve a current image. A current variation ratio between first rows of pixels of the current image and second rows of pixels in a previous image is calculated. When both the current variation ratio and a previous variation ratio are determined to be larger than a ratio threshold, a detected flicker number is incremented. When the detected flicker number is determined to be larger than a flicker number threshold, a flicker condition is determined to occur. When the detected flicker number is determined to be not larger than the flicker number threshold, the current image becomes the previous image and the current variation ratio becomes the previous variation ratio such that a next image becomes the current image to repeat the above steps.

An optical filter in the optical filter assembly and the lens are parallel and located on different planes, and when the optical filter is in a filtered state, the optical filter is located on one side of the photosensitive element facing the lens for reducing an intensity of light entering the photosensitive element.

An image sensor includes a plurality of pixels, where each of the plurality of pixels includes a photodiode. The image sensor is configured to capture images of a scene exposed with a flickering light source by for each of the plurality of pixels, acquiring a value representative of a light level at a corresponding pixel by gradually varying a value of sensitivity of the corresponding pixel.

Systems and methods are disclosed herein to detect pixels exhibiting anomalous behavior in captured image frames. In some examples, temporal anomalous behavior may be identified, such as flickering pixels exhibiting large magnitude changes in pixel values that vary rapidly from frame-to-frame. In some examples, spatial anomalous behavior may be identified, such as pixels exhibiting values that deviate from an expected linear response in comparison with other neighbor pixels.

There is provided an optical sensor that acquires a first image frame corresponding to a first flicker period and acquires a second image frame corresponding to a second flicker period. The optical sensor respectively adds pixel data of every two pixels in neighboring rows of the first image frame and the second image frame to generate a low-resolution image frame for the motion detection.
