ethod and device for colour adjustment // 2628532
FIELD: physics.SUBSTANCE: method of colour adjustment is proposed, and it comprises: obtaining frame data from a frame buffer; converting the frame data from the original colour space to the linear original colour space by a reverse gamma correction process to obtain the frame data in the linear original colour space; converting the frame data in the linear original colour space to a linear target colour space to obtain frame data in the linear target colour space; and performing gamma correction of the frame data in the linear target colour space using the target gamma coefficient to obtain the frame data in the target colour space.EFFECT: in the invention by performing the inverse data frame gamma correction process from a frame buffer, transformation past inverse gamma correction on frame data in the linear target colour space and performing the frame data to gamma correction in the linear target colour space for receiving the frame data in the target colour space, solved the problem of inconsistent effects display of the same data frame to multiple devices, the effect is realised in accordance to coordinated display and the same data shot on different devices.9 cl, 5 dwg

ethod for correcting gradation and device or method for determining thresholds for epsilon-filter // 2611005
FIELD: physics.SUBSTANCE: each value of the discrimination threshold corresponding to each obtained luminance value, which is intended to be assigned for each panel gradation unit, is received by the gradation correcting method. The pixel value corresponding to each discrimination threshold value is obtained for each panel gradation unit. The threshold epsilon-filter value is obtained by the inverse gamma-correction of the relationship between the distinct values of the discrimination threshold corresponding to the panel gradation units and the maximum panel output value. Based on the linear approximation function, they are obtained by the method of the least squares. The threshold epsilon-filter value is defined as the increasing function of the pixel value on the basis of the permitted number of steps of the discrimination threshold values and is changed according to the central pixel value.EFFECT: reduction of the image distortion caused by the halo effect.12 cl, 9 dwg

Colour selection system // 2505867
FIELD: physics.SUBSTANCE: computer implemented method for assisting in colour selection involves associating, depending on a mathematical equation derived from measurements of psycho-physical responses of a certain set of test subjects to a first set of control colours, a colour emotion score with each of a second set of colours that are numerically defined in a colour library; displaying on a visual user interface a combination of at least three colours from the colour library; displaying on the visual user interface the combined colour emotion score for said combination of colours; the combined colour emotion score is calculated using a controller as follows: (a) calculating for each unique colour combination pair of adjacent colours the colour emotion score of a pair of adjacent colours using a first equation depending on the colour emotion score of each colour of the pair of adjacent colours; (b) calculating for each unique colour combination pair of non-adjacent colours the colour emotion score of a pair of non-adjacent colours using a second equation depending on the colour emotion score of each colour of the pair of non-adjacent colours; (c) wherein the combined colour emotion score = 1/n (Σ colour emotion score of the pair of adjacent colours + Σ colour emotion score of the pair of non-adjacent colours), where n is the total number of unique pairs of adjacent and non-adjacent colours of the colour combination.EFFECT: facilitating colour selection using a controller without the need for the user to select a primary colour.48 cl, 17 dwg

ethod for generation of sprite // 2405205
FIELD: information technologies.SUBSTANCE: sprite represents images of irregular shape overlaid over background images, preferably online. Generated sprite has specified first multitude of possible values of non-transparent colours of pixels and at least one value of pixel colours identifying transparent colour of pixel. Sprite is generated using initial data, including the first data structure specifying colour image with specified second multitude of possible colours of pixels, and the second data structure specifying non-transparent part of specified sprite. Compliance of colours of the first data structure and possible non-transparent colours of sprite is partial projection of the specified second multitude into the specified first multitude, where augmentation of area of identification of specified partial projection to the specified second multitude is the multitude, capacity of which is considerably lower than capacity of the specified second capacity, besides to identify the value of colours included into the specified first multitude and complying with colour of pixel from the first data structure, the following actions are taken: if pixel of the first data structure has colour that does not belong to the specified area of identification, then value of this pixel is established as equal to colour being one of nearest to initial colour of pixel and included in the specified area of identification; specified partial projection is applied to colour of pixel of the first data structure.EFFECT: improving sprite generation reliability.5 cl, 2 dwg

Interactive carrier and method for control of additional data for it // 2374701
FIELD: information technologies.SUBSTANCE: player, in which interactive disk is installed, obtains access to server, which provides additional content in the form of audio/video data recorded on interactive disk prior to reproduction of interactive disk, and obtains updated information of additional content from server; addresses to obtained updated information and decides, whether arbitrary file contained in additional content list related to audio/video data has been updated; requests initial file contained in list or updated file, specified in updated information, and obtains requested initial or updated file.EFFECT: expansion of functional resources.19 cl, 5 dwg
