JEITA CP-3451 Explication - 140 - �|If the captured scene type as well as saturation, sharpness and contrast are recorded, it is up to the reader which of these to use. �|Processing examples are given in the table below for each objective. Explication Table 1 Examples of Processing for Different Scene Types Processing Objective Processing Example Normal To make the ordinary scenery look more attractive Normal processing Landscape To     make     the     landscape scenery look more attractive Enhancement  of  contrast,  saturation, and sharpness Portrait To   make   the   subject   look more attractive Memory color correction of skin color Night Scene To make the night scene look more attractive Inhibition of soft tone correction Noise reduction 7.3.12GainControl Tag Information This tag indicates the degree of overall image gain adjustment. [Writer] �|The writer records the difference in gain in relation to the default (factory setting) sensitivity. The default sensitivity may differ for each writer. �|If there is more than one default value, this tag is not used. [Reader] �|The reader can estimate the degree of noise occurrence in accord with the recorded value. �|Other tags (exposure time, shutter speed, brightness, captured scene type, etc.) may be used as supplementary information. 7.3.13    Contrast/Saturation/Sharpness Tag Information The Contrast tag indicates the direction of contrast processing applied by the camera when the image was shot. The Saturation tag indicates the direction of saturation processing applied by the camera when the image was shot. The Sharpness tag indicates the direction of sharpness processing applied by the camera when the image was shot. [Writer] �|The writer records the difference in contrast, saturation and sharpness in relation to the default (factory setting) values. �|The defaults may differ for each writer. [Reader] �|The reader should understand that the recorded values are for the purpose of print processing and should avoid over-correction or processing that defeats the purpose of the recorded values. �|Processing examples are given in the table below for each objective.
