Image processing device for adjusting characteristic data based on reference image and image display apparatus using the same

Abstract: In an image display apparatus of the present invention, at a predetermined timing, a characteristic data setting module actuates a reference image signal generation module to generate an analog reference image signal, based on reference image data prepared in advance. The characteristic data setting module then controls a signal selector module to select the analog reference image signal. An A-D converter module converts the analog reference image signal selected by the signal selector module into a digital image signal according to preset characteristic data. The characteristic data setting module adjusts the characteristic data set in the A-D converter module to make image data expressed by the digital image signal input from the A-D converter module into an image conversion processing module approach to the reference image data. This arrangement ensures easy adjustment of the operating characteristics of the image display apparatus.

Backup image stitching method and device based on binocular camera

Abstract: The invention discloses a backup image stitching method and device based on a binocular camera. The method comprises the following steps: acquiring an image collected by the binocular camera, converting the image to generate a aerial view, acquiring rotation angle and speed information of a front shaft center point of a vehicle, computing the rotation amount and translation amount of the current frame image relative to a starting frame image according to the rotation angle and the speed information, performing image conversion on the current frame image according to the rotation amount and thetranslation amount, and stitching the converted image to a starting frame, and then acquiring the backup trajectory of the vehicle, and displaying the backup trajectory on a panoramic image, therebydisplaying a large-angle backup image top view to a user. The accuracy of the backup image is effectively improved, the use demand of the user is satisfied, and the user experience is improved.

Apparatus and method for transforming an image in a mobile device

Abstract: An image conversion device in a mobile apparatus and a method thereof are provided to support a real-time making environment for an image obtained from the field, thus a user can make the user's own UCC in real time as registering the UCC in a web environment A pen style converter(206a) converts an original image into a pen style by using a separation Gaussian filter, and outputs the converted pen style A cartoon style converter(206b) converts the original image into a cartoon style, and outputs the converted cartoon style A mosaic generator(206c) generates a photo mosaic to be applied to the original image, based on an optimum photo image set The mosaic generator applies the generated photo mosaic to the original image to output the image An image output unit outputs the outputted images to an output device

Image generation apparatus and method for energy subtraction

Abstract: PROBLEM TO BE SOLVED: To reduce influences of a motion artifact in generating a radiographic image for energy subtraction by continuous exposure of radiation of three times or more. SOLUTION: In an image generation apparatus for energy subtraction, a detection part in an X-ray detector 2 detects radiation of N patterns (N is a natural number of 3 or larger) different in energy distribution continuously exposed to a subject for each pattern and an image conversion part converts the detected radiation into a digital image signal, so that digital image data for the radiographic image representing the subject is generated. To the image generation apparatus for energy subtraction, a photography control unit 4 for controlling the image generation apparatus so that the number of pixels of the radiographic image obtained by the N-th radiation exposure becomes larger than that of the radiographic image obtained by the first to the (N-1)th radiation exposures, is added.

3D-image conversion apparatus and method for adjusting depth information of the same

Abstract: A 3D-image conversion apparatus and a method of adjusting depth information of the same are provided. The three-dimensional (3D) image conversion apparatus includes a depth information generator which generates depth information with regard to an input image; an object detector which detects an object having parallax exceeding a preset range in a left-eye image and a right-eye image corresponding to the input image based on the generated depth information; a depth information adjuster which adjusts depth information of the object by adjusting the parallax of the detected object to be within a preset range; and a rendering unit which renders the input image according to the adjusted depth information. With this, a viewer's fatigue can be minimized in the case of converting a 2D image into a 3D image.
