摘要： PROBLEM TO BE SOLVED: To ensure that easily visible display is performed in spite of a fluctuation in the observation environment. SOLUTION: The picture data adjusted in the number of pixels in a number-of-pixel adjustment processing section 1 is separated to Y (luminance) data and C (chromaticity) data in YC separation processing section 2. The Y data is subjected to gradation correction processing meeting a gradation correction signal 81 in a gradation correction processing section 3. The C data is subjected to saturation correction processing meeting a saturation correction signal 82 in a saturation correction processing section 5. The Y data subjected to the gradation correction and the C data subjected to the saturation correction are converted to RGB data in a YC/RGB conversion processing section 6 and is subjected to prescribed color subtraction processing in a color subtraction processing section 7 and is outputted. An observation environment decision section 8 decides the observation environment of a display element 33 based on the information associated with the observation environment and outputs the gradation correction signal 81 and saturation correction signal 82 meeting the observation environment.

摘要： PROBLEM TO BE SOLVED: To provide a camera and an apparatus for recording additional information of an image capable of recording items of additional information desired by a user with required information accuracy. SOLUTION: After a user selects an 'additional information' menu from a setting picture displayed on a camera for recording additional information such as a photographing condition or the like by each photographed image and confirms the setting of additional information at present, the user can enter propriety of revision of the setting. When the user gives instruction to revise the setting, the camera displays a list of additional information items to be settable and also displays the remaining capacity of an additional information recording area and the number of setting available items together with the current setting contents. The user can designate any one of 'OFF (no recording)', 'STD ON (recording with ordinary accuracy)', and 'Fine (recording with high accuracy)' as to each information item. When photographing is executed after the designation of the items to be recorded and information accuracy, the additional information is recorded on an image file according to the setting. Moreover, the item can be deleted/added after the image recording. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide an image processor capable of improving the tone of an image photographed under restricted exposure conditions according to utilizations and features of an image input device. SOLUTION: A Y/C conversion part 18 converts R, G and B data of the inputted image into a brightness signal Y and chroma signals Cr and Cb. A Y histogram calculation part 20 produces a histogram of the brightness signal Y. A LUT (look-up table) calculation part 22 calculates a correction coefficient for flattening the histogram and calculates the LUT for correcting the brightness signal Y. The correction coefficient is adjusted by an intensity coefficient inputted from an intensity coefficient input part. The intensity coefficient is a coefficient for applying an inclination to the correction of the brightness signal Y and preset by the type, characteristics, an installation place, and the utilizations of the image input device 12. The intensity coefficient is set according to the system to be used so as to correct the tone according to the system. COPYRIGHT: (C)2003,JPO
