A system includes a storage device storing a set of instructions and at least one processor in communication with the storage device. When executing the instructions, the at least one processor is configured to cause the system to obtain a first operation mode of the optical filter and determine a brightness value of visible light of ambient light. The at least one processor may also cause the system to obtain a brightness threshold related to the first operation mode, compare the brightness value of the visible light of the ambient light with the brightness threshold, and determine whether a switching condition is satisfied based on the comparison result. Upon the determination that the switching condition is satisfied, the at least one processor may further cause the system to switch the first operation mode of the optical filter to a second operation mode.

The accuracy of rolling shutter distortion correction for captured images is improved. Posture information corresponding to a line of an input image is calculated. Then, a first virtual line, which is a line in a line direction of the input image for which the posture information calculated is common, is rotated according to the posture information to obtain a second virtual line on the output image. For each pixel of the output image, a corresponding second virtual line is calculated, and posture information is obtained on the basis of the corresponding second virtual line. Then, for coordinates of each pixel of the output image, the reference coordinates on the input image corresponding to the pixel coordinates is calculated using the associated posture information. By cutting out the output image from the input image on the basis of the reference pixel, highly accurate distortion correction can be realized even in a case where the camera posture differs depending on the line.

A control section 45 sets an exposure timing and an exposure period for imaging pixels for acquiring an imaging picture and light intensity detection pixels for detecting intensity of illumination light individually by an imaging section 21. A correction gain calculation section 32 calculates a flicker correction gain for each of the imaging pixels on the basis of pixel signals generated by the imaging pixels and pixel signals generated by the light intensity detection pixels. A flicker correction section 33 uses the flicker correction gain for each imaging pixel calculated by the correction gain calculation section 32 to perform flicker correction of the imaging pixel. Accordingly, an imaging picture can be obtained on which the influence of fluctuation of the intensity of emission light is reduced irrespective of the positional relationship between an illumination apparatus and an imaging object.

An imaging system includes an imaging device that images a predetermined imaging area, an illumination device that performs irradiation with illumination light so as to illuminate an imaging area and is capable of adjusting a light amount of the illumination light for each of local regions narrower than the imaging area, and a control unit that controls the imaging device and the illumination device. Then, a high-luminance region having a luminance value exceeding a predetermined luminance range is detected in an image captured by the imaging device, and a light amount of illumination light with which the illumination device irradiates a local region corresponding to the high-luminance region is determined to be a reduction light amount reduced to be less than a light amount with respect to overall of the imaging area. The present technology can be applied to, for example, a camera system for operation.

A compound-eye capturing apparatus provided with a plurality of imaging devices captures a plurality of items of image data with the same image quality. First pixels for generating first pixel signals are arranged in a first pixel array part. Second pixels for generating second pixel signals are arranged in a second pixel array part. A first setting part sets an exposure time and a first gain for the first pixel signals on the basis of an appropriate exposure value. A second setting part adjusts the first gain on the basis of a difference in sensitivity between a first monocular camera module provided with the first pixel array part and a second monocular camera module provided with the second pixel array part, and sets the adjusted first gain as a second gain for the second pixel signals. A control part causes the first and second pixel array parts to be exposed over the exposure time. An amplification part amplifies the output first and second pixel signals by the first and second gains.
