Mobile communication terminal had a function of transformation for a picture

Abstract: PURPOSE: A mobile communication terminal including an image conversion function is provided to display images per area to a 3D space based on distance information of a 2D image. CONSTITUTION: A coordinate selection unit(110) selects 2D coordinates from a real time photographing image. An area partition unit(120) divides space which is formed by the selected 2D coordinates. An image photographing unit(130) photographs the divided space images. A distance measurement unit(140) measures the distance about the space images. An image processing unit(150) displays the space images which is photographed in a 3D space to the 3D space.

Image processing method, image processing apparatus, and imaging apparatus

Abstract: PROBLEM TO BE SOLVED: To satisfactorily correct deterioration of image quality caused by a change in the attitude of an imaging apparatus.SOLUTION: An image processing apparatus 20 comprises an image acquisition unit 22 which acquires as an input image an image generated by imaging via an optical system 11 by an imaging apparatus 10; an attitude acquisition unit 21 which acquires information representing the attitude of the imaging apparatus taken at the time of imaging; a filter acquisition unit 21 which creates or selects an image conversion filter in accordance with the attitude represented by the information; and a processing unit 22 which performs filtering processing on the input image using the image conversion filter. The image processing apparatus 20 can be included in the imaging apparatus.

Image processing device, image forming apparatus, and computer-readable non-transitory storage medium with image processing program stored thereon

Abstract: An image processing device includes a data acquisition unit, an instruction receiving unit, an image conversion pattern storage unit, and an image processing unit. The image conversion pattern storage unit stores a plurality of image conversion patterns having different dot thinning ratios and scaling ratios corresponding to the respective image conversion patterns, in which the image conversion patterns having smaller dot thinning ratios are mapped to greater scaling ratios. The image processing unit reads the image conversion pattern mapped to the scaling ratio designated for the n-up printing out of the image conversion pattern storage unit when the instructions to carry out the n-up printing and the toner-saving printing are received by the instruction receiving unit, and performs image processing on the image data acquired by the data acquisition unit using the image conversion pattern.

Image correction device, image correction method and program

Abstract: PROBLEM TO BE SOLVED: To display an image with sufficient appearance without applying a load to a distribution side of the image even if a distribution destination of the image does not have an image conversion function corresponding to a device characteristic of a display device.SOLUTION: A device information acquisition section 103 of a server 1 acquires device characteristic information on a display section 401 of an electronic terminal 4 of a user. A simulated image generating section 102 generates a simulated image obtained by simulating a distribution object image stored in an image data storing section 105 on the display section 401 in response to acquired device information and transmits the simulated image to a display section 301 of an electronic terminal 3 of a creator with the distribution object image. The creator compares the simulated image with the distribution object image, and corrects the distribution object image if need. The distribution object image is corrected from a plurality of electronic terminals 4 so that luminosity shift in two display sections where the luminosity shift is maximum in a positive direction and a negative direction is reduced among the display sections 401, for example.

Method for image conversion with error diffusion

Abstract: A method of image conversion takes an original print ready image at a first resolution scaling and orientation, and simulates printing that image by creating (12) a representation of a page at the particular resolution, scaling and orientation. The image is then periodically sampled (14) through the page with an aperture that corresponds to the desired output. Because the resolution, scaling and/or orientation of the "print" and "scan" are distinct, the aperture "sees" areas which may correspond to more than a single pixel on the original image, and thereby may derive a signal that is gray, i.e., the aperture may see an area that is neither completely black or white, and the image data derived will be considered gray. The gray image data, which may be definable at several bits per pixel, is then made print-ready by reducing (16) the number of bits defining each pixel to a valid output state (0, 1 for a typical binary printer, 0, 1, 2, 3 for a quaternary printer, etc.). The reduction step is accomplished through error diffusion methods that maintain the local area gray density level. In color applications, each of the bitmaps representing a color separation, be it 2, 3, 4 or any other number, is treated independently with the same method.
