Optical flow is calculated for each patch on the basis of two images, and then a region having low confidence and a region having high confidence are separated depending on confidence of the optical flow, and the optical flow in the region having low confidence is interpolated using the optical flow in its surrounding regions.

A method for merging real and synthetic images in real time is comprised of the steps of providing a first signal containing depth and image information per pixel about a real image. A second signal containing depth and image information per pixel about a synthetic image is provided. The depth information corresponding to the real image and the depth information corresponding to the synthetic image for each pixel are compared. Based on the comparison, either the image information corresponding to the real image or the image information corresponding to the synthetic image is selected and combined. Because the image information is compared based on depth, any interaction such as occluding, shadowing, reflecting, or colliding can be determined and an appropriate output generated

A system to be installed within a room for detecting indoor condition data such as the interior area of the room and the number and position of occupants therein comprises an LED array for emitting a spotlight to form a multiplicity of light spots one by one successively as dispersed on the interior surface of the room at approximately equal spacings. The spotlight is projected from the array on the interior surface and concentrated on a one-dimensional PSD upon reflection. The indoor condition data is calculated by using triangulation for the optical system and output currents of the PSD as input signals.

A sublimation type thermal transfer color video printer generates a heating pulse having a duration corresponding to the tone level of the pixel to be printed, according to the data in a reference tone table stored in a memory, to energize the corresponding heating element of a thermal heat during the duration. The tone table includes a variable data which is the basis of determining the duration of the first energizing pulse required up to right before the coloring of a recording paper, and a fixed data which are the bases of determining the durations of subsequent energizing pulses. A variable value multiplied by these fixed data is set in a separate register. The variable data in the tone table and the variable value in the register are rewritten according to change in temperature of the thermal head.

Thermal transfer video printer having improved temperature correction

The thermal transfer printer of the present invention is provided with a cam follower mounted on a thermal transfer head in one body and an eccentric cam, which is controlled within a semicircle so as to be positioned at either a first position for releasing it from the cam follower to press the thermal transfer head to a platen or a second position for pressing it to release the thermal transfer head from the platen, as a construction for pressing the thermal transfer head to the platen and releasing the thermal transfer head from the platen, whereby the mechanism for pressing the thermal transfer head to the platen and releasing the thermal transfer head from the platen itself can be remarkably small-sized and is simple in action due to its remarkably small working quantity, the printer can be small-sized as a whole and improved in reliability of operation as well as durability. Furthermore, the thermal transfer printer can be stably carried out the subsequent controls after initial powering, since the positional relation between the thermal transfer head and the platen is controlled so as to be initially set to the predetermined relation without delay when it is initially powered.
