A full-range image detecting system including a planar light source, an image capturing device, a light sensing device, a processing unit and a measuring module is provided. The planar light source projects a photo image with periodical variations onto an object. The image capturing device captures a reflective photo image reflected from the object. The light sensing device detects the coordinates of at least three measuring points on the object for fitting a plane. The processing unit calculates a phase variation of the reflective photo image after phase shift, a relative altitude of the surface profile of the object according to the phase variation, and an absolute altitude of the surface profile of the object with respect to the plane to obtain an information of absolute coordinate. The measuring module detects the surface of the object according to the information of absolute coordinate of the object.

An image capture apparatus that can aid in the generation of desired three-dimensional data, and a control method for the same are provided. Based on parallax images obtained by using an image sensor, three-dimensional information of a subject included in the parallax images is obtained. A comparison is made between a resolution of the three-dimensional information set and a resolution of a predetermined formative apparatus, and whether or not recapturing is required is judged.

An imager may include depth sensing pixels that provide an asymmetrical angular response to incident light. The depth sensing pixels may each include a substrate region formed from a photosensitive portion and a non-photosensitive portion. The depth sensing pixels may include mechanisms that prevent regions of the substrate from receiving incident light. Depth sensing pixel pairs may be formed from depth sensing pixels that have different asymmetrical angular responses. Each of the depth sensing pixel pairs may effectively divide the corresponding imaging lens into separate portions. Depth information for each depth sensing pixel pair may be determined based on the difference between output signals of the depth sensing pixels of that depth sensing pixel pair. The imager may be formed from various combinations of depth sensing pixel pairs and color sensing pixel pairs arranged in a Bayer pattern or other desired patterns.

An imaging device is provided that includes an image blur evaluator, an imaging processor, a distance map generator and a filter. The image blur evaluator evaluates the amount of blurring due to a camera shake. The imaging processor captures a plurality of secondary images of the same object at different lens positions by driving a photographing lens. The distance map generator prepares a distance map including distance information of the objects captured in each area of an image based on the contrast in each of the areas. The filter reduces noise in the distance map. A relatively large filter size is selected for the filter when blurring is evaluated to be relatively large and a relatively small filter size is selected for the filter when the evaluated blurring is relatively small.

A range finder adapted for finding the object distance of a subject having a specific height includes a shell unit, an objective lens assembly, a magnifying unit having multiple selectable magnification ratios, and a range finding unit. The range finding unit includes a scale, a pointer, and a mark. The object distance of the subject is known by comparing the scale and the pointer in an imaging plane when an end of an image of the specific height of the subject formed on the imaging plane is aligned with the mark.
