The present invention relates to a system and method of viewing pairs of perspective images of 3-D objects (i.e. stereoscopic image pairs) displayed from a CRT display surface in a time-multiplexed or field-sequential manner, and more particularly to a universal method of generating control signals for synchronously changing the optical state of liquid crystal (LC) shutter panels through which the time-multiplexed perspective. images can be sequentially viewed in a substantially flicker-free manner by the left and right eyes of a human viewer, independent of whether the images are displayed on NTSC, PAL, VGA or SVGA styled CRT display devices.

A printer-built-in image-sensing apparatus including a camera which performs image sensing with film exposure, and a printer which prints an image sensed by the camera. After a shutter button has been pressed and image sensing with strobe light emission has been performed, if printing is instructed by pressing of a print button, then electric charging a capacitor of a strobe circuit is made after the completion of the print operation. Otherwise, the charging of the capacitor is started immediately after the image sensing. In this case, even if printing is instructed during the electric charge, printing is started after completion of the electric charge. Thus, electric consumption upon print operation can be reduced and fluctuation of voltage can be suppressed.

By suppressing deviation of dot-formation positions stemming from insufficient accuracy in conveying a printing medium due to eccentricity of a conveying roller, a printed image in which unevenness is less visible is obtained.

Moreover, the nozzles used when the nozzle-use range is narrowed are not fixed, and are switched to be used as appropriate. This prevents only certain nozzles from being used concentratedly, and allows all of the nozzles to maintain substantially the same ejection performance.
