Title: Gradation conversion method for picture
Inventor: NUMAKURA TAKASHI
IPC: G03F3/08
Filed: 1989-05-31
Abstract: PURPOSE:To obtain an excellent print picture having a picture characteristic with fidelity to an object by using picture information relating to a luminous quantity such as 1st order exposure obtained from the object as a basis. CONSTITUTION:A density characteristic curve being a characteristic of a recording medium indicating the correlation between picture information in correlation with a density of an original picture obtained from the recording medium (longitudinal axis-D-value) and a picture information value in correlation with luminous quantity made incident on the recording medium from an original picture (lateral axis-X-value) is specified. Then the picture information value in correlation with luminous quantity of a picture element corresponding to the picture information value in correlation with the density of an optional picture element on an original picture is obtained. Then the picture information value in correlation with the luminous quantity of the original picture thus obtained is converted into a gradation intensity by using a specific gradation conversion equation. Thus, the tone of the original picture is reproduced with fidelity.

Title: Portable video telephone terminal
Inventor: SABURI KAZUMITSU
IPC: H04M1/656
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To enable two-way communication that automatically answers when an incoming call comes and includes at least an image. SOLUTION: A personal identification number for specifying the other party allowed to perform automatic answering speech communication and mode information showing whether or not an automatic answering mode is set are stored in a memory. When an incoming call comes, a CPU first decides whether the automatic answering mode is set (S2) and collates the personal identification number in received call out data with the personal identification number stored in the memory (S4) in the case the decided result is 'Yes'. As a result, when the personal identification numbers coincide with each other, automatic answering is set and two-way communication through an image and sound is made available (S5).  Meanwhile, when the automatic answering mode is not set, when the personal identification number is not inputted yet or when the personal identification numbers do not coincide, normal answering is performed (S3).

Title: Improvement of color correction table
Inventor: SUYAGARAJIYAN BARASUBURAMANIAN
IPC: H04N1/46
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of measurement items through the selection of a few improved colors and to improve a color correction table within a smaller time at a lower cost. SOLUTION: A color image forming system has a color correction table 10 connecting to a printer 12. A set xi of improved colors is selected to decide the accuracy of the system. The selected number of improved colors is less than the number of locations in the color correction table 10, i.e., 1 to 50%. The printer 12 prints out a color patch of a corresponding color to decide a corresponding photometric value x' for each improved color (x). An improved table 16 is generated, where the value x' is mapped onto the value (x) by using an error difference between the values x, x'. An interpolator 22 interpolates a known error over the improved table based on a total of weighting of known errors. The weighting is inversely proportional to the Euclid distance of interpolated errors from the known errors.
