Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include determining a fixation point of a user's eyes. Location information associated with a first virtual object to be presented to the user via a display device is obtained. A resolution-modifying parameter of the first virtual object is obtained. A particular resolution at which to render the first virtual object is identified based on the location information and the resolution-modifying parameter of the first virtual object. The particular resolution is based on a resolution distribution specifying resolutions for corresponding distances from the fixation point. The first virtual object rendered at the identified resolution is presented to the user via the display system.

There is provided a small sized imaging apparatus which can measure with high accuracy a color distribution of a surface of an object, in which a light intensity distribution on a predetermined surface in a direction substantially perpendicular to an optical axis is uniform, and a change in an amount of light in a direction along the optical axis is reduced, and an illuminating unit which used in this imaging apparatus. (The imaging apparatus) Includes a light source section (210) which supplies illuminating light, a diffusing section (211) which diffuses by reflecting the illuminating light from the light source section (210), and aperture sections (212a and 212b) which allow to emerge diffused illuminating light, and the aperture sections (212a and 212b) has an aperture diameter D which allows the diffused illuminating light to emerge as a substantially parallel light.

A fuel gas production apparatus includes a vaporization mechanism, a reforming mechanism, a PSA mechanism, a supply passage, a combustion air supply mechanism and an ECU. The vaporization mechanism has a combustion catalyst for vaporizing a fuel. The reforming mechanism reforms the vaporized fuel to obtain a reformed gas. The PSA mechanism refines the reformed gas by removing impurities to produce a fuel gas. The impurities removed by the PSA mechanism are continuously supplied as a heat source fuel to the vaporization mechanism through the supply passage. The combustion air supply mechanism supplies combustion air to the vaporization mechanism. The ECU controls the amount of the combustion air supplied to the vaporization mechanism synchronously with the change in the amount of heat energy of the impurities supplied to the vaporization mechanism.

An avatar display system in virtual space, an avatar display method in virtual space, and a computer program in which avatar motion data is thinned out within a certain time due to the circumstances of a system and is intermittently distributed. Accordingly, when avatars try to high-touch with each other, the avatars go too far before the hands touch each other in the transmission of coarse motion data, and thus a natural avatar operation cannot be performed. When avatars are intended to perform an operation with contact, such as a high touch operation between the avatars, as the avatars approach each other, a transmission interval in which data required for rendering avatars such as motion data, or rendered avatar data is transmitted from a server to a client terminal is made smaller, and a more natural avatar contact operation can be performed.

The present invention provides an ink jet printing apparatus and an ink jet printing method which are capable of stabilizing the amount of ink ejection and of printing a high-definition image by selecting a driving condition with heat conductivity of an electrothermal converter being taken into consideration. The heat conductivity from a heater to ink is classified into heater ranks, and, on the basis of the heater rank, a voltage of a drive pulse to be applied to the heater is changed.
