In a distance information obtaining device comprising an image pickup device (10) for picking up an optical image of an object to produce a picture signal, and a signal processing unit (18) for processing the picture signal to produce a processed signal representative of distance information between the image pickup device and each point of the object, the signal processing unit produces a reference signal by using a reference picture signal derived from the image pickup device on a preliminary ...

An image projection device includes a distance measuring device which determines a screen distance between the image projection device and a screen. An image sensor captures a shape of the screen and a screen detector detects a sensor-view shape of the screen from the captured image of the screen. The sensor-view shape of the screen is transformed to a projector-view shape of the screen by a coordinate transformer based on the screen distance. A controller modifies an image to be projected so as...

By using a spectral reflectance of a projection plane or color information under a light source, which is stored in wall color storage means 4, matrix calculation means 5 calculates a conversion matrix, and mixing amounts R, G, B of primary colors of an input image are converted into corrected mixing amounts R', G', B', and they are projected by means of a projector. Thereby, even in a case where a wall is colored, correct color reproduction is made in a colorimetric manner.

A method and a system for video recording, in which scenes desired by a user can be recorded, are provided. Even at a case that the user sets the starting time and the ending time of a program beforehand and its broadcasting time is changed, and at a case that the user does not know the contents of the program in detail, the program or the scenes desired by the user can be recorded by the method and the system. The method for video recording provides the steps of; detecting an inputted face imag...

A method and a device of light source discrimination, skin color correction, and color image correction, and storage medium thereof capable of being read by a computer always enable reproducibility, of color to be maintained highly regardless of difference of light source. There is calculated color distribution of portion of a face or skin in image by color distribution calculation section. There is compared the color distribution with distribution of skin color taken photograph under respective...

An enquiry face image shot by a video camera and the like is collated with face image data converted into database. The data converted into the database are three-dimensional shape data of surfaces of faces and color image data. Shooting conditions (an angle and lighting directions) of the enquiry image are supplied to the data, and thereby a color image of each person's face from the database in accordance with the shooting conditions is generated. By comparing the color image with the enquiry ...

For obtaining distance information between an image pickup device (10) and an object (11) illuminated by a monochromatic beam selected by a diffraction grating (18) from an optical beam generated by an optical beam generator (27), a distance information obtaining device comprises an activating device (33) for simultaneously activating the beam generator and the image pickup device a predetermined time duration so that the optical beam generator generates an optical beam while activated and so th...

A coloring support apparatus comprises a table storage section to store a coloring table having an emphasis column for describing the degree of color emphasis of a domain in a linear graphic image to be colored, and a color coordinate column for describing a color coordinate value in any color space in the domain to be colored for each image element constituting the linear graphic image, a whole color tone column for describing the impression of coloring; a color number determination section for...

In an image deforming method and an image deforming apparatus, a portion of an input image is geometrically deformed to be outputted therefrom. Input and output image buffers keep input and output image data items, respectively. An image deforming method and a partial deformation region are specified in an image deformation specification unit. For each pixel of the output image, a before-deformation coordinate value calculating section calculates coordinate values thereof before the deformation....
