Higher overall etch rate and throughput for atomic layer removal (ALR) is achieved. The reaction is a self-limiting process, thus limiting the total amount of material that may be etched per cycle. By pumping down the process station between reacting operations, the reaction is partially “reset.” A higher overall etch rate is achieved by a multiple exposure with pump down ALR process.

The specification and drawings present a new method, apparatus and software product for enhancing a dynamic range of an image with a multi-exposure pixel pattern taken by an image sensor of a camera for one or more color channels, wherein a plurality of groups of pixels of the image sensor have different exposure times (e.g., pre-selected or adjusted by a user through a user interface using a viewfinder feedback, or adjusted by a user through a user interface after taking and storing RAW image, etc.). Processing of the captured image for constructing an enhanced image of the image for each of the one or more color channels can be performed using weighted combination of exposure times of pixels having different pre-selected exposure times according to a predetermined criterion.

A panoramic high-dynamic range (HDR) image method and system of combining multiple images having different exposures and at least partial spatial overlap wherein each of the images may have scene motion, camera motion, or both. The major part of the panoramic HDR image method and system is a two-pass optimization-based approach that first defines the position of the objects in a scene and then fills in the dynamic range when possible and consistent. Data costs are created to encourage radiance values that are both consistent with object placement (defined by the first pass) and of a higher signal-to-noise ratio. Seam costs are used to ensure that transitions occur in regions of consistent radiances. The result is a high-quality panoramic HDR image having the full available spatial extent of the scene along with the full available exposure range.

Techniques for creating a High Dynamic Range (HDR) image within a consumer grade digital camera from a series of images of a scene captured at different exposure levels, and displaying the HDR image on the camera's built-in display are provided. The approach employs mixing images of the series to incorporate both scene shadow and highlight details, and the removing of “ghost” image artifacts appearing in the mixed HDR image resulting from movement in the scene over the time the series images are captured. The low computational resource utilization of the image mixing and ghost removal processing operations, along with the ability to commence image mixing and ghost removal prior to the acquisition of all series images, can significantly reduce the time required to generate and display a tone mapped HDR image.

A method for resolution enhancement of a still-image made by a digital imaging device. The method allows the use of high-aperture-ratio sensing arrays that produce resolution-enhancement, independent of the angle of view. Resolution-enhancement is achieved using a multiple-exposure technique of a sub-pixel overtap in conjunction with a whole-pixel shift. The method suppresses color-aliasing in a multiple-exposure native-resolution mode and enables the use of a single camera for single-exposure and multiple-exposure modes.

The purpose of the invention is to provide a solid model creation apparatus that is small in size and inexpensive. A multiplicity of blue LEDs are prepared, optical fibers are connected thereto, and GRIN lenses are arranged at the ends of the tips of the respective optical fibers to constitute an exposing head 23. The exposing head 23 forms images of the end faces of the respective optical fibers in a photocurable resin exposure region 24 as light spots 55. The diameter of a light spot 55 is, for example, 0.5 mm, but the size of a pixel 71 within the exposure region 24 is much smaller; for example, 62.5mu. The multiplicity of optical fibers at the exposing head 23 are arrayed in a matrix such that they are displaced in staggered fashion so that respective light spots 55 are lined up at the pitch 62.5mu of the pixels 71 in the primary scan (Y-axis) direction. As the exposing head 23 scans the exposure region 24 in the secondary scan (X-axis) direction, all of the light spots capable of directing light onto appropriate pixels, these being the respective pixels 71 to be cured within the exposure region 24, are turned on and multiple exposure is carried out.
