Condensation associated with the collection and identification of airborne particles is detected. Upon the detection, one or more condensation countermeasures are triggered to address the condensation.

An image processing apparatus according to a first aspect of the present invention acquires a first image and a second image in a first image acquisition mode, or a second image acquisition mode in which a second image acquisition ratio is higher than in the first image acquisition mode, on the basis of a detection result of a specific target (whether or not a specific target has been detected, what type of specific target). For example, in accordance with whether or not a specific target has been detected and the type of specific target, the first image and the second image can be acquired in the first image acquisition mode in a case where the necessity for acquiring the second image is low, whereas the first image and the second image can be acquired in the second image acquisition mode, in which the second image acquisition ratio is high, in a case where the necessity for acquiring the second image is high.

There is provided a system (100) comprising a light source (110), an imaging unit (120) configured to capture a plurality of images of an subject, wherein each of the plurality of images is captured at an exposure time shorter than the wave period of the pulsed illumination, wherein the pulse frequency of the illumination is not a multiple integral of the frame rate at which the images are captured, and wherein a total time during which the plurality of images is captured is at least half of the wave period of the pulsed illumination, and a control unit (130) configured to: obtain a predetermined number n of candidate images, generate a sorted list of pixels by sorting respective pixels, apply a set of weights to the respective sorted list of pixels, and generate an estimated ambient light corrected image based on the plurality of weighted and sorted lists of pixels.

An imaging system includes a light emitter that emits light toward the surroundings of a vehicle, an imager that captures an image of a range including a region that is illuminated with light emitted by the light emitter, and a difference image generator that generates (n−1) difference images from n captured images captured by the imager (n is an integer no smaller than 3). The difference image generator generates a difference image based on an image included in the n captured images and captured while the light emitter is on and an image included in the n captured images and captured while the light emitter is dimmed.

A method for detecting lost image information via a lighting device and an optical sensor. The lighting device and the optical sensor are controlled so as to be chronologically aligned with each other. A visible spacing region in an observation region of the optical sensor is determined from the chronological alignment of the control of the lighting device and the optical sensor. A recording of the observation region with the optical sensor is generated via the aligned control. Image information is identified in the recording in regions outside of the spacing region visible in the image, so as to make the identified image information accessible.
