Title: Electronic photographic method
Inventor: YAMAZAKI TOORU
IPC: G03G15/01
Filed: 1981-01-09
Abstract: PURPOSE:To perform other discoloring and color conversion as well as erasing of black part by using a single layer photoreceptor, by respectively forming a nonmagnetic toner image in correspondence with the black part of an original image and that in correspondence with the colored part of an original image. CONSTITUTION:After a photosensitive drum 1 is uniformly charged with a charger 2, the exposure of image is made by an exposure 3. Electrostatic latent image of the part corresponding to the black part is formed by using a red filter as a color decomposition filter 4. Uniform charge is made by a charger 2 while keeping a black magnetic toner on the photoreceptor drum 1 to form electrostatic latent image corresponding to the black and red parts by using a cyan filter afterwards. Development is made by a development device 6 accommodating a nonmagnetic toner to obtain the nonmagnetic substance layer toner image corresponding to the colored part of the original. Thus, the black part is erased by using a single-layer photoreceptor and color decoloring and conversion can be made also.

Filed: 1983-01-10
Abstract: PURPOSE:To simplify the constitution and to attain high speed response by extracting a part corresponding to a color burst signal in an output of a level comparing means as a phase discriminating signal. CONSTITUTION:Each output of an adder circuit 12 and a subtractor circuit 13 is applied to a level comparision circuit 14, which compares a signal level of each output of the adder circuit 12 and the subtractor circuit 13, and when a signal level of the output of the adder circuit 12 is larger than the signal level of the output of the subtractor circuit 13, the circuit 14 produces a, e.g., high level output and when other than the case, the circuit 14 produces a low level. Thus, while the phase of the color burst signal is discriminated by a signal adding a PAL chrominance carrier signal having the color burst signal and an output of a delay means delaying the PAL chrominance carrier signal and a signal in response to the difference of both the signals, the pahse discriminating signal is generated at each other 2H depending on the phase of the color burst signal, then the constitution not including a period detector or the like is attained.
