To provide an image decoding method allowing decoding of a multiview video even when no prefix NAL units are used. The image decoding method includes: parsing NAL units of a base view; decoding an image of the base view; parsing MVC extension parameters of a non-base view; searching whether or not prefix NAL units for a base view are present; either computing MVC extension parameters for the base view when no prefix NAL units are present or parsing the MVC extension parameters of the base view when prefix NAL units for the base view are present; and decoding the non-base view using the MVC extension parameters of the base view and the MVC extension parameters of the non-base view.

In a moving image coder for coding each of a plurality of blocks obtained by dividing an input image, an effective area that can be referenced in an inter-frame coding reference image is defined. A reference area is detected that should be referenced for the inter-frame coding of a target block in the reference image. For the reference area belonging to the effective area, an image in the above reference area is outputted. For the reference area not belonging to the effective area, a prediction image for the inter-frame coding is generated by outputting a supplemental image. The input image is coded by using the prediction image.

In motion search using a PE array, a technique is provided for enabling high-speed calculation while avoiding bank conflict without increasing a memory for storing pixels outside the screen. When pieces of pixel data of a plurality of lines to be read from the memory 3 (reference image memory 30 ) exist in a same bank, the conflict bank anticipatory read control unit 10 reads pixel data of a line in advance, and a read data holding circuit 20 holds the data until timing for inputting to a PE array unit 4 . Accordingly, bank conflict can be avoided when reading pixel data from the memory 3 , so that smooth pipeline processing by the PE array unit 4 can be realized.

PROBLEM TO BE SOLVED: To provide an image reader by which sufficient amount of pixel value information for collation (similarity calculation) or the like can be obtained through the storage of pixel values of a few pixel numbers. SOLUTION: An image reader 100 is provided with an image storage means, that stores image information consisting of a set of pixel values and with a coordinate transformation information storage means that stores coordinated transformation information to replace at least either of x or y coordinate value of input coordinates with coordinate values for access to the image storage means, and also with a coordinate replacement means that accesses the coordinate transformation information storage means for replacing the x or y coordinate values inputted for accessing the image storage means, and an image read means 104 that accesses the image storage means to extract a pixel value on the basis of the x coordinate value or they coordinate value, outputted from the coordinate replacement means and/or on the basis of they coordinate value or the x coordinate value that is received and not replaced.
