The imaging optical module has an object lens group, in which an axial symmetric phase coding is added, to produce an axial symmetric spherical aberration. A point spread function (PSF) and an image with extended depth of field can be obtained with a predetermined level of similarity. The phase/intensity converting module converts the phase change of the light passing the phase object, into an image light with change of light intensity.

摘要： An auto-focusing lens module includes an object lens, a liquid zooming unit, and an image lens group. The object lens and the liquid zooming unit receive an object image in front and condense the image into a first-stage output light. A zoom quantity is determined by an external control on the liquid zooming unit. The image lens group including a first and second lens receives the first-stage output light to transmit a second-stage output light. The first lens has a first and second surface, in which the second surface is farther than the first surface to the liquid zooming unit and has a convex curving surface protruding toward an image sensor. The second lens has a first and second surface, in which the first surface has a concave curving surface indenting toward the image sensor to adapt at least a portion of the convex curving surface of the first lens.

摘要： A method and an apparatus for designing an image restoration filter and a method and an apparatus for restoring an image by using the image restoration filter are provided. A test image is captured by an imaging system to obtain image information of the test image. The image restoration filter is then calculated according to original image information of the test image and the image information obtained by the imaging system through a numerical method, such that the obtained image information after being processed by the image restoration filter has a better similarity to the original image information. Thereafter, an image captured by the imaging system is processed by using the image restoration filter as a kernel, so as to resolve the problems of image blur and distortion caused by the optical path and the imaging system.

摘要： A zoom lens formed in a small size adaptable to a thin and portable device, having three lens groups, including, from the object plane to the image forming plane: a first lens group with a negative power, a second lens group with a positive power and a third lens group with a positive power. By controlling the ratio of the focal length of the second lens group and the focal length of the tele-photo end, image distortion may be controlled, and the total length of the lens may be reduced to shrink the size of the lens. Hence production costs may be reduced, which is important to mass production.
