Abstract: In a vehicular camera, an image generation unit generates at least one image of a directional view from a vehicle, and an object recognition unit recognizes a target object in the at least one image. A region identification unit identifies, in the at least one image, a specific region in the target object recognized by the object recognition unit. A vehicle control unit performs a vehicle control task based on the recognized target object. A mosaic unit identifies a specific region in the at least one image corresponding to the specific region in the at least one image, and performs a mosaic task to thereby blur a mosaic region in the second image. The mosaic region includes at least the specific region in the at least one image.

Abstract: A histogram generator generates a histogram based on luminance values of respective pixels of an image. The histogram represents a relationship between each of the luminance values of the image listed in a predetermined axis and the number of pixels for the corresponding one of the luminance values. An image corrector calculates, based on the histogram, a luminance increment caused by the light reflected from the cover member, and translates, based on the luminance increment, the histogram in a negative side of the predetermined axis of the histogram to accordingly generate a corrected histogram. The corrected histogram has (i) an estimated least luminance value lower than the least luminance value, and (ii) an estimated most luminance value lower than the most luminance value. The image corrector generates, based on the corrected histogram and the image, a corrected image.

Abstract: In an image processing apparatus, an image acquirer is configured to acquire a captured image from a camera mounted to a vehicle. A histogram generator is configured to generate a histogram representing a relationship between a luminance and a pixel count of the captured image. The pixel count is a number of pixels in the captured image. An image corrector is configured to generate a corrective tone-curve for correcting the relationship between the luminance and the pixel count of the captured image based on the histogram of the captured image, and correct the captured image using the corrective tone-curve to generate a corrected image. The corrective tone-curve is a tone-curve representing a relationship between input and output values of luminance.
