Abstract: A projection system is provided which includes a projection lens and a spatial optical modulation device (SOM) for projecting an image in response to an inputted picture signal. A control unit enables the selection, via an image adjustment menu, of at least one of a rotational deformation adjustment in which a projected image is rotated and a keystone deformation adjustment in which the projected image is deformed into a rectangle, and the control unit applies a rotational deformation adjustment and a keystone deformation adjustment to the projected image based on an item selected in the image adjustment menu in response to a deformation indication inputted from a keys/indicators unit, so as to deform the projected image.

Abstract: When a user selects an initial brightness adjustment quantity setting mode by a mode key operation of a digital camera, an initial brightness adjustment quantity setting screen is displayed on a liquid crystal display in place of an initial screen. When the user inputs and sets an arbitrary initial brightness adjustment quantity by a cursor key operation, the input and set initial brightness adjustment quantity is stored in a non-volatile memory. Thereafter, when a power supply is turned off and then the power supply is again turned on, the brightness adjustment operation relative to an imaging device is executed by using the initial brightness adjustment quantity stored in the non-volatile memory.

Abstract: In a color image printing apparatus, image data is printed on a recording paper by using a thermal printing head through ink ribbons constructed of cyan, magenta, and yellow-colored ribbons. A single pixel of the image data is formed by a preselected dot number of areas. Within this area, the cyan, magenta, and yellow colors are printed out by dot numbers corresponding to density data of the respective colors. The cyan color data is printed out in such a way that while the density data thereof is increased, the dot number is successively increased from a predetermined printing position within this area. The magenta and yellow color data are printed out in such a manner that while the density data thereof are increased, the dot numbers are successively increased from different printing positions other than the above-described cyan printing position.
