Image conversion device

Abstract: PROBLEM TO BE SOLVED: To correct an image of an output video signal without increasing the circuit scale and processing load on a device, and also without deteriorating the picture quality of the output video signal even when an input video signal and the output video signal are different in frame rate. SOLUTION: When a count value of a period counter is 1 (S105), a motion vector rate conversion unit reads a first coefficient KAn out of a motion vector conversion table (S106). Arithmetic processing (MVx=MVn×KAn) for performing rate conversion on a motion vector MVn of 50 Hz that a motion vector detection unit detects in S103 is performed to obtain a motion vector MVx of 60 Hz (S107). Once the MVx is outputted from the motion vector rate conversion unit, an image correction unit performs image correction processing to a video signal of 60 Hz outputted from the image rate conversion unit using the MVx according to predetermined algorithm (S108).

Communication system and mobile terminal

Abstract: A communication system is equipped with a mobile terminal and a controller of an industrial machine for forming a shaped product. Mutual communications are carried out between the controller and the mobile terminal. The mobile terminal includes an image capturing unit for capturing an image of an object to be imaged, an image conversion unit which converts the captured image data captured by the image capturing unit and generates converted image data according to an image format rule corresponding to the controller, a setting data creation unit which creates setting data for the converted image data, so that the converted image data can be used by the controller, and a data transmission and reception unit which carries out communications with the controller and transmits the converted image data and the setting data to the controller.

Method for compensating details of digital image

Abstract: The invention relates to a method for compensating details of a digital image, which is applied to compensate the details of an original image picked up by a digital pick-up device. The method comprises the steps of: loading the original image, carrying out at least one image treatment procedure for the original image to generate a temporary storage image, storing detail data of the temporary storage image, meanwhile, carrying out at least one image conversion program for the temporary storage image selectively, and carrying out a mixing program for the temporary storage image subjected to the image conversion program and the detail data stored in advance to obtain a complete image.

Image conversion display device

Abstract: PURPOSE:To perform image conversion at high speed, by adding values set at two registers corresponding to the content of the image conversion by two adders fitting to the scan of a converted image, calculating the image element of an original image, and reading out image information from an image memory CONSTITUTION:The values of the X-axis and the Y-axis of a reproducing image element that become the starting point of the display of the converted image are set on the registers 1 and 6, respectively, and the displacement quantities of the coordinate values in an X-axis and a Y-axis directions in the original image between the reproducing image elements neighboring to each other of the converted image in a sub scan direction are set at the registers 2 and 7, respectively, and the displacement quantities in the X-axis and the Y-axis directions in the original image between adjacent two reproducing image elements in a main scan direction of the converted image are set at the registers 4 and 9, respectively An accumulator 3 performs addition and accumulation by inputting the contents of the registers 1 and 2 as initial values corresponding to scan by the instruction of an indicator 14, and an accumulator 5 outputs the value of the X-axis by adding and accumulating the content of the register 4 on the above value Similarly, an accumulator 10 outputs the value of the Y-axis An indicator 11 reads out the image information of the image element represented by the X-axis and the Y-axis values from the image memory 12 in order, and displays them on a display device via a video signal generator 13

Display system for driving vehicle

Abstract: PURPOSE: A driving assist display system for a vehicle is provided to calculate the moving distance of a vehicle based on the moving distances of feature points before and after movement, thereby easily grasping the position relation between peripheral obstacles and vehicles. CONSTITUTION: A driving assist display system for a vehicle comprises a vehicle detection unit(12), a feature point extracting unit(17), an image conversion unit, and an image synthesizing unit. The vehicle detection unit detects the state of a vehicle. The feature point extracting unit processes video and extracts feature points. The image conversion unit converts overlapped images using the feature points of the images according to the state of the vehicle. The image synthesizing unit synthesizes an created image with the real image, wherein the created image is created based on three-dimensional position relation by the feature point extracting unit and the real image is obtained by capturing the surrounding of the vehicle using a camera(14).
