Abstract: Provided are devices for camera cleaning and flare reduction for vehicles, which can include a cleaning device for cleaning a transparent window of a housing containing a camera system. The devices can include optical panels with different properties that can be moved in front of the transparent window for flare reduction. Methods are provided which can include analyzing at least one image to determine a presence of an optical flare within the at least one image, and, based on detecting the optical flare, causing at least one optical panel to be moved into a position in front of a lens of the imaging device. Computer program products are also provided.

Abstract: Provided are methods for processing raw data for sensors with multiple color channels, which can include receiving raw image data associated with an image sensor, wherein the raw image data includes a plurality of groups of pixels including a first group of pixels associated with a first filter and a second group of pixels associated with a second filter. The methods may also include generating, from the raw image data, a plurality of wavelength-based data groups including a first wavelength-based data group and a second wavelength-based data group. The first wavelength-based data group may include first pixels corresponding to the first group of pixels and the second wavelength-based data group may include second pixels corresponding to the second group of pixels. The methods may also include encoding the first wavelength-based data group and the second wavelength-based data group. Systems and computer program products are also provided.

Abstract: Provided are methods for cascade camera image signal processing (ISP) tuning, which can include receiving first image data at a first time associated with a first image sensor of a camera, generating at least one tuned first ISP block parameter for at least one first ISP block based on the first image data and first tuning criterion, receiving second image data at a second time, and generating at least one tuned second ISP block parameter for at least one second ISP block based on the second image data and second tuning criterion. Some methods described also include tuning parameters of at least one ISP block of a camera after receiving tuned parameters. Some methods describe also include generating an image using ISP blocks tuned using various tuning criteria. Systems and computer program products are also provided.
