A photographing apparatus is disclosed. A photographing apparatus according to one embodiment comprises: a first image sensor; a second image sensor; and at least one processor functionally coupled to the first image sensor and the second image sensor, wherein the at least one processor may be configured to: obtain, by using the first image sensor, a first image which includes a first pixel, a second pixel adjacent to the first pixel, and a third pixel adjacent to the second pixel in an area other than the area in which the second pixel and the first pixel are adjacent; obtain, by using the second image sensor, a second image which includes a fourth pixel associated with the first pixel on the basis of the position thereof, and a fifth pixel adjacent to the fourth pixel and associated with the second pixel on the basis of the position thereof; determine whether a difference in luminance between the first pixel and the second pixel falls within a designated range; and, when the difference in the luminance between the first pixel and the second pixel falls within the designated range, generate color information corresponding to at least one of the first pixel and the second pixel at least on the basis of the color information of the fourth pixel and the color information of the fifth pixel.

Systems and methods for extended color processing on Pelican array cameras in accordance with embodiments of the invention are disclosed. In one embodiment, a method of generating a high resolution image includes obtaining input images, where a first set of images includes information in a first band of visible wavelengths and a second set of images includes information in a second band of visible wavelengths and non-visible wavelengths, determining an initial estimate by combining the first set of images into a first fused image, combining the second set of images into a second fused image, spatially registering the fused images, denoising the fused images using bilateral filters, normalizing the second fused image in the photometric reference space of the first fused image, combining the fused images, determining a high resolution image that when mapped through a forward imaging transformation matches the input images within at least one predetermined criterion.

An interactive projector is provided with a projection section adapted to project an image on a screen surface, a detection section, and a correction section. The detection section detects presence or absence of contact of the pointing element with the screen surface based in a relationship between a difference between a Z-coordinate value of the pointing element and a Z-coordinate value of the screen surface, and a difference threshold value set in advance. The correction section corrects at least one of the Z-coordinate value of the screen surface, the Z-coordinate value of the pointing element, and the difference threshold value based on a history of the Z-coordinate value of the pointing element.

In general, techniques are described that facilitate processing of color image data using both a mono image data and a color image data. A device comprising a monochrome camera, a color camera, and a processor may be configured to perform the techniques. The monochrome camera may capture monochrome image data of a scene. The color camera may capture color image data of the scene. A processor may determine a parallax value indicative of a level of parallax between the monochrome image data and the color image data and determine that the parallax is greater than the parallax threshold. The processor may further combine, in response to the determination that the parallax is greater than the parallax threshold, a luma component of the color image data with a luma component of the monochrome image data to generate a luma component of enhanced color image data.
