ABSTRACT:
In a color picture image recording apparatus using a photosensitive and pressure-sensitive recording sheet having on its surface pressure rupturable microcapsules each containing a photosensitive material and a chromogenic material selected from cyan, magenta and yellow, and a mechanical strength of the microcapsule varies when exposed, a color tone of a reproduced picture image can easily be adjusted by the provision of a filter unit. The filter unit is used in conjunction with a radiation unit which radiates onto the photosensitive and pressure-sensitive recording sheet a light carrying a color image of an original to form a latent image, and includes filters each selectively passing a light of a particular wavelength which causes to vary the mechanical strength of one of the cyan-, magneta-and yellow-containing microcapsules. Each of the filters is movably disposed on a light path so as to change its filtering characteristic, whereby when the photosensitive and pressure-sensitive recording sheet is pressure-developed, the color tone of the reproduced color image can be adjusted.
