A method and apparatus are provided for correcting for optical misalignment of the dual (left and right) images produced by a stereo electronic endoscope, or of the corresponding dual images produced by coupling electronic imaging devices to each of two monocular teaching ports of a stereo optical endoscope. The stereo image alignment technique comprises electronically capturing the video image data of the dual images, and subsequently processing that data electronically to correct for optical alignment errors. The method involves digitizing the electronic data and digitally performing the equivalent of vertical image shift, and / or image size change, and / or image rotation as required to correct for any visual image misalignment.

The present invention relates to an image processing apparatus and an image processing program, and an image processing method for making various operations be performed more comfortably. A rotation input section 14 is provided substantially at the center of a mobile phone 1. When the rotation input section 14 is rotated in a clockwise or counterclockwise direction, an image displayed on a display section 13 is rotated to be displayed. In addition, when the rotation input section 14 is pressed at an upper, lower, left or right portion thereof toward inside of the mobile phone 1, a display range of the image displayed on the display section 13 is switched. For example, in a case where a map is displayed, the map is rotated when the rotation input section 14 is rotated, and the map is scaled up / down when a predetermined position of the rotation input section 14 is pressed. The present invention may be applied to mobile phones.

Rotation in the storage domain is a one-one function with the domain equal to the range. This permits an image to be rotated in place. Each image size implies at least one garland of closed chains of pixels. Each image includes a spanning set of these garlands. Rotation in place moves each pixel to the next location on its garland. On completion of a garland by return to the initial pixel, pixels on the next garland are moved. Image rotation is complete after all the garlands have been traversed.

A conversion control unit divides a transform coefficient into code blocks. A storing device has a storage capacity corresponding to data size of the code blocks. To the conversion control unit, rotation / inversion control information including information of the rotation angle and the inverting direction is input. The conversion control unit generates a control signal on the basis of the rotation / inversion control information and sub-band information of the transform coefficient. An address generating unit generates a write address on the basis of a control signal. By accessing the storing device in predetermined order on the basis of the write address at the time of writing the code block to the storing device, an image rotating / inverting process is performed.

Image rotations of 90°, 180° and 270° and horizontal and vertical mirroring image transformations are performed losslessly and with greatly enhanced speed by processing orthogonal transform coefficients in a zig-zag order with direct storage of S (size) values, reassociated R (run of zero valued coefficients) from an adjacent coded orthogonal transform value and a non-zero valued transformation coefficient in reverse zig-zag order. Cache misses are avoided by processing values which are not widely separated in the coded data and other features of the technique and memory accesses are reduced to accelerate processing while extremely little computation is required. These effects are substantially augmented when intermediate codes having certain attributes including coding of zero valued coefficients and flagging certain code features are employed.
