A compact high quality and lightweight symbol generator for projecting symbolic information into the field of view of a viewfinder is provided. The symbol generator comprises at least one ESBG device sandwiched between a pair of transparent plates which together function as a total internal reflection lightguide, switching electrodes and means for coupling illumination into the lightguide. Each ESBG device contains information encoded in a multiplicity of separately switchable grating regions. A plurality of independently switchable transparent electrodes elements, substantially overlay the separately switchable grating regions. When no electric field is applied, the ESBG device is in its diffracting state and projects images of said information towards the viewer. The projected images are surimposed onto an image of the external scene. When an electric field is applied the ESBG no longer diffracts and hence3 no information is displayed. In a further embodiment of the invention, the symbol generator could be configured to provide symbols of different colors by arranging for different symbols to contain ESBGs optimized for the required wavelengths and LEDs of appropriate spectral output. In a yet further embodiment of the basic invention several ESBG panels could be stacked such that by selectively switching different layers it is possible to present a range of different symbols of differing colors at any specified location in the field of view.

The invention allows an image printing on a wide range of print media regardless of how much ink the print media absorb, without sacrificing a high printing flexibility of an ink jet printing system. To this end, the image forming method of this invention includes: a process of modifying a surface of an intermediate transfer body by applying energy to the surface; a process of ejecting ink onto the surface-modified intermediate transfer body by using an ink jet printing device; and a process of transferring ink from the intermediate transfer body to a print medium.

A light flux control member has a back face provided with a recess and a ring-like-recess-portion surrounding the recess. Output light of a point-like-light-source (light emission element) is incident to the recess and the ring-like-recess-portion. Incident light to the recess is emitted from a light control emission face after inner-propagation. Incident light to the ring-like-recess-portion is refracted as to hardly generate inner-propagation light deflected to directions near to a direction of reference optical axis L, resulting in outgoing from any part of the light control emission face, or, if some outgoing occurs from the light control emission face, such outgoing occurs only at an outer periphery portion of the light control emission face. As a result, illumination light quality is avoided from being reduced by appearance of conspicuous ring-like bright part. In addition, uniform illumination light can be supplied to a broad angle range. Even if a plurality of point-like-light-sources are arranged at intervals, respective light fluxes originated from respective point-like-light-sources are well mixed.
