Abstract: The present disclosure relates to an imaging device, an imaging method, an electronic apparatus, and an onboard electronic apparatus for suppressing the flicker caused by light sources over a wide range of frequencies.With the present technology, multiple images are captured consecutively at uneven intervals in a single-frame period of a video before being blended. This removes the flicker efficiently. The uneven capture timing in the single-frame period is made the same for multiple frames. This makes it possible to prevent low-frequency flicker from getting higher in frequency. The present disclosure may be applied to onboard cameras, for example.

Abstract: There is provided an image capturing apparatus comprising an image capturing unit. A control unit controls the image capturing unit to capture a first image having exposure unevenness caused by flicker in a light source. A detection unit detects a timing at which there is a low change in a light amount caused by the flicker, based on the exposure unevenness in the first image. An accepting unit accepts an image capturing instruction. The control unit controls the image capturing unit to capture a second image at the detected timing in response to the image capturing instruction.

Abstract: An approach is provided to adjust a camera shutter lag. In the approach, data is collected that corresponds to an ambient light found in a physical environment with the ambient light being controlled using a pulse-width modulation (PWM). The pulse-width modulation corresponds to a PWM timing model. When an exposure request is received, the camera shutter lag is calculated using the PWM timing model. The calculated shutter lag is based on a future point in time at which the ambient light of the physical environment is predicted to be at a selected light output level, such as a power level selected by the user of a camera. When the calculated camera shutter lag has expired, a shutter of the camera is opened causing a camera lens to be exposed that results in a captured exposure.
