An imaging system () includes an imaging unit () configured to capture an image of a target object while the imaging unit () being mounted on a movable apparatus (); and an exposure condition determination unit () configured to determine any one of a fixed exposure condition and an automatic exposure (AE) condition, as an exposure condition, based on a distance detected between the movable apparatus () and the target object.

Imaging system which determines an exposure condition based on a detected distance

An image processing device includes an image input unit, a shake-amount measuring unit, a shake correcting unit, a dividing unit, a feature-value calculating unit, and an enhancement processing unit. The image input unit receives an input of an image in chronological order. The shake-amount measuring unit measures an amount of shake of an image. The shake correcting unit corrects shake of the image in accordance with the amount of shake measured. The dividing unit divides the image corrected into multiple areas. The feature-value calculating unit calculates a histogram indicating a feature value of an image, for each of the divided areas. The enhancement processing unit determines processing details of enhancement processing to change a form of the histogram for each of the areas in accordance with the measured amount of shake of the image, and conducts enhancement processing on the area based on the histogram calculated for each area.

Image processing device and recording medium

An image processing system, an image processing device, and image processing method are provided. Each of the image processing system, the image processing device, and the image processing method includes dividing an image into a plurality of areas according to a predetermined division condition, measuring an optical transmittance of each of the plurality of divided areas or data correlating with the optical transmittance as transmittance data, calculating the optical transmittance or the data correlating with the optical transmittance from the image as the transmittance data, determining a parameter for adjusting a contrast for each of the plurality of areas according to the transmittance data obtained by the measuring or the calculating, and adjusting a contrast of each one of the plurality of areas using the parameter determined by the determining.

A projection display device according to the invention includes a separating unit that assigns X separation information for identifying a type of an image to each pixel by using a characteristic amount of the input image, a luminance detecting unit that detects a luminance of a screen, a first determining unit that determines a first target region indicating a region on which halftone processing of converting the number of gradations is performed on the input image by using the X separation information, and a halftone processing unit that executes the halftone processing that varies depending on the luminance on the first target region.

Projection display device, projection display method, and computer program

An image projecting apparatus includes an image projecting unit configured to project received original image data on an image projection surface; an area identifying unit configured to identify an obstruction area in which different content is displayed as compared to a normal projection surface to be projected based on the original image data; and a layout modifying unit configured to modify a layout of an object included in the original image data that is projected, on the basis of the object and the obstruction area on the image projection surface.

Image projecting apparatus, image processing method, and computer-readable storage medium

A detecting unit detects output-prohibit area information indicating an output-prohibit area from image data. An identifying unit identifies the output-prohibit area in the image data based on the output-prohibit area information detected by the detecting unit. A masking unit performs a masking on the output-prohibit area identified by the identifying unit. A rearranging unit rearranges an image of an area other than the output-prohibit area over the output-prohibit area on which the masking is performed by the masking unit. An outputting unit outputs image data obtained by rearranging the image by the rearranging unit.
