摘要： An apparatus and method for detecting a three-dimensional image. The apparatus includes a projector which projects a reference light on an object; an image sensor which senses an image of the object; and a controller for controlling the projector and the image sensor, wherein the image sensor includes an aperture that restricts the passage of entering light; and an aperture controller for setting an aperture value for the aperture when receiving a two-dimensional image input, and setting an aperture value for the aperture when receiving a three-dimensional image input. The aperture value is set based on the intensity of received reference light. A processing unit determines the position of the object based on a relationship between an illumination direction of the reference light at the determined time center Npeak and an entrance direction of the reference light relative to the target pixel. A flicker detector detects a change frequency in light received by the image sensor, and the controller controls the image sensor to sense frames of an image at a frequency which is a multiple of the detected change frequency.

摘要： An image reader capable of outputting excellent quality read images, without illumination irregularities, similar to that of flat documents even when the document surface is curved as in the case of book-like documents. An image reader provided with a memory to store correction data to correct differences of illumination of each pixel of a document image, and which corrects the read information of each pixel in a document image using correction data corresponding to the measured height of a document surface among correction data stored in the memory. For one aspect, this image reader is constructed so as to correct a group of read information corresponding to a set of pixels arrayed in one direction by excluding specific frequencies among the illumination distribution from the set.

摘要： In a solid-state image sensing device, a method for driving the solid-state image sensing device, and an image sensing system incorporated with the solid-state image sensing device of the invention, pixel signals having two or more different photoelectric conversion characteristics to be outputted from a pixel section are amplified by using an analog gain with respect to each of the photoelectric conversion characteristics for outputting the amplified pixel signals. This enables to reproduce an image having a wide dynamic range while suppressing lowering of the frame rate.
