An apparatus is disclosed for displaying to a viewer an image stereoscopically representing a three-dimensional object to be displayed. The apparatus includes: an emitter emitting light, having an intensity modulating section capable of intensity modulation for modulating an intensity of the light emitted from the emitter; a wavefront-curvature modulator capable of wavefront-curvature modulation for modulating a curvature of wavefront of the light emitted from the emitter; and a controller controlling the intensity modulation and the wavefront-curvature modulation, based on a luminance signal indicative of luminance of the image, and a depth signal indicative of depth of the image. The depth signal is a signal corresponding to depth data produced in a rendering process for the object to be displayed.

Image display apparatus and signal processing apparatus

An optical scanning device is constituted without using any arc sin .theta. correction lens, while maintaining quality of an image. The optical scanning device comprises an optical flux generator, a resonance-type deflection element, a drive signal generator and a dot clock generator that is configured to sequentially generate dot clocks which satisfy a first, second and third condition, wherein the optical flux generator radiates the optical fluxes having brightnesses corresponding to the clock cycles of the dot clocks generated by the dot clock generator.

In accordance with a printing data, resistive thermo-generating elements in a thermal head are selectively heated to a relatively high temperature and a heat-fusible solid ink on an ink ribbon is thereby melted and the melted ink is transferred to a printing paper, thereby printing characters on a printing sheet. The printed characters can be erased by contacting to the printed portion of the printing sheet the ink ribbon heated by the thermal head to a relatively low temperature. In order to prevent the printing and erasing qualities from being deteriorated due to the change in the environmental temperature, the duration of current application to the resistive thermo-generating elements is compensated for individually for printing and erasing modes in response to the change in the environmental temperature.
