TL;DR: In this paper, an image processing device that receives a plurality of individual images including at least two images that form a stereoscopic image and generates a display image displaying the plurality of input individual images simultaneously on a display unit is presented.
Abstract: An image processing device ( 10 a ) that receives a plurality of individual images including at least two images that form a stereoscopic image and generates a display image displaying the plurality of input individual images simultaneously on a display unit. The image processing device includes an image conversion unit ( 111 ) that converts at least one image among the input images that form the stereoscopic image into a planar image, and an image generation unit ( 151 ) that generates the display image by synthesizing the planar image that has been converted by the image conversion unit ( 111 ) and an image among the plurality of input images that has not been converted into a planer image by the image conversion unit ( 111 ).

TL;DR: In this paper, the authors proposed a method for detecting compromised applications and an apparatus, the method comprising: calculating a verification code of an application installed on a terminal; after the application is launched, acquiring a first image associated with an upload operation of the application, the upload operation being triggered by using a function of the program; processing, by using the verification code, data of the first image, and generating a second image according to the processed data, a visual effect of the second image being similar to that of the original image; and providing the two image to a server.
Abstract: A method for detecting a compromised application and an apparatus, the method comprising: calculating a verification code of an application installed on a terminal; after the application is launched, acquiring a first image associated with an upload operation of the application, the upload operation being triggered by using a function of the application; processing, by using the verification code, data of the first image, and generating a second image according to the processed data, a visual effect of the second image being similar to that of the first image; and providing the second image to a server. The server compares whether the verification code obtained from image conversion is identical to an official verification code, so as to determine validity of a current application program. The invention enables a verification code of an application to be hidden in normal user data and reported, so as to provide the advantage of preventing hackers from detecting an integrity check process.

TL;DR: A moving image compression device has an obtaining unit, an image conversion unit, and a compression processing unit as mentioned in this paper, where the obtaining unit obtains a RAW moving image having plural frames associated in an order of imaging, the frames having pixels of three different color components which are disposed periodically according to a color array with two rows and two columns.
Abstract: A moving image compression device has an obtaining unit, an image conversion unit, and a compression processing unit. The obtaining unit obtains a RAW moving image having plural frames associated in an order of imaging, the frames having pixels of three different color components which are disposed periodically according to a color array with two rows and two columns. The image conversion unit separates, in a target frame, a first pixel group corresponding to a first color component of odd rows and a second pixel group corresponding to the first color component of even rows, and alternately arrays, in a time base direction, a first image including the first pixel group and a second image including the second pixel group. The compression processing unit performs inter-frame prediction coding compression on the first image and the second image.

TL;DR: In this paper, an X-ray image conversion screen for reflection geometry Xray imaging devices that detects, by an optical detector, an emission image from the Xray incidence surface side of the x-ray conversion screen is presented.
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray image conversion screen with which it is possible to capture an X-ray image with high sensitivity that excels in picture quality.SOLUTION: Provided is an X-ray image conversion screen for reflection geometry X-ray imaging devices that detects, by an optical detector, an emission image from the X-ray incidence surface side of the X-ray image conversion screen. The X-ray image conversion screen includes a support substrate 2 and a phosphor layer 3 laminated on the support substrate, the phosphor layer containing an oxysulfide gadolinium phosphor, with at least one selected from the group consisting of Tb, Pr, Ce, Yb and Eu used as an activator. When an X-ray of effective energy 30 keV or greater is incident from the surface on the side of the phosphor layer where the support substrate is nonexistent, luminous energy y emitted from the surface satisfies formula (1): y≥1.15x (where, x represents luminous energy emitted from the surface when an X-ray of effective energy 30 KeV or greater is incident from the surface of an X-ray scintillator screen DRZ-high from Mitsubishi Chemical Co.).SELECTED DRAWING: Figure 1
