摘要:
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 ) = ∫ b x [ 1 / r ( ξ ) ] ⅆ ξ ( 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.

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.

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.

There is provided a disc array control method and apparatus for controlling access to a disc drive consisting of a plurality of second data obtained by dividing a first data and a plurality of discs for storing the error correction data for the second data. Particularly, the disc array control method and apparatus of the present invention determines the information consisting of disc storing a plurality of the second data and address on the disc, data size of a plurality of second data and disc storing the error correction data and address on the disc to make equal the time required for access to a plurality of second data and error correction data and executes the access to the disc drive on the basis of the determined information. Thereby, the time required for access to the error correction data and sub-blocks can be set to equal time and the real-time property can be assured while maintaining high reliability.

A reordering device 1.sub.-- 1 rearranges the segments of each block of time series data comprised of a plurality of blocks in block units. A selecting device 2.sub.-- 1 selects from among a plurality of time series data S1.sub.-- 1 to 1.sub.-- 4 rearranged by the reordering device 1 by switching in accordance with the speed and transmits the corresponding segments of the selected time series data sequentially to the reordering device 3.sub.-- 1 etc. as the streams S2.sub.-- 1 etc. The repeat reordering device 3.sub.-- 1 rearranges the segments contained in the stream S2.sub.-- 1 in units of blocks so as to restore the original order and transmits this rearranged time series data.
