摘要:
This invention makes it possible to produce a high quality synthesized panoramic image when it is difficult to highly precisely shift the image pickup direction. The present invention provides an image pickup apparatus for synthetically generating a first image, or a whole image of an entire object of shooting, the apparatus comprising an image pickup section that sequentially changes the image pickup direction and picks up section of images of the object of shooting to be imaged, a reading section that reads second images, each having a predetermined width and constituting a part of the image picked up on an imaging plane in the image pickup section, a defining section that defines a reading range of each second image to be read by the reading section, a relative position identifying section that identifies the relative position of each second image relative to the first image, and a synthesizing section that generates the first image by sequentially and synthetically combining the second images read out by the reading section, the defining section being adapted to determine the first quantity of movement of each second image by referring to the relative position thereof as identified by the relative position identifying section and define the reading range of the second image to be read out next according to the first quantity of movement.
摘要:
A whole image showing the entire range of the object of shooting is generated by picking up unit images, each constituting a part of the scenic range to be imaged, by sequentially shifting the image pickup direction, cutting out image regions of a predetermined size, each constituting a part of each of the unit images picked up in the image pickup step, so as to produce overlapping areas and sequentially and partly superposing the image region. The noise components of the image regions are uniformized to improve the image quality by cutting out image regions as to make two or more than two image regions overlap each other in average for the position of each unit image of the whole image to be generated.

A signal conversion apparatus which converts an input signal x from an image sensor into an output signal y by a function relation represented by Expression 1: y=f(x)=∫bx[1/r(ξ)]dξ (1) where b is a predetermined constant, ξ is an integration variable corresponding to a value of the input signal x, and r(ξ) is a quantization step function before removal of a noise of the input signal x, which determines an increment of the input signal x to an increment of the output signal y.

An image processing apparatus includes a pattern generating unit that generates a plurality of two-dimensional array patterns, a radiating unit that emits light in each of the two-dimensional array patterns generated by the pattern generating unit to irradiate an object with the light, a spectrum measuring unit that measures the spectrum of the light, which is emitted from the radiating unit and is reflected by the object, in a plurality of frequency bands to generate spectral data, a transmission-rate calculating unit that calculates the transmission rate of each frequency band on the basis of the two-dimensional array patterns and spectral data blocks associated with the respective two-dimensional array patterns, and an image generating unit that generates an image in a desired frequency band on the basis of the transmission rates calculated by the transmission-rate calculating unit.
