An information processing apparatus and method is disclosed wherein setting data to be used in image pickup can be set precisely to perform desired image pickup. The information processing apparatus may include a recording control section configured to control recording of image data obtained by image pickup and setting data used in the image pickup, and a reproduction section configured to reproduce the setting data. The information processing apparatus may further include an acceptance section configured to accept a variation amount to a value corresponding to the setting data inputted by a user, and a variation section configured to vary the setting data reproduced by the reproduction section based on the variation amount accepted by the acceptance section. The recording control section may control recording of the setting data varied by the variation section. The invention can be applied typically to a personal computer.

Information processing apparatus and information processing method as well as program

An image sensing apparatus and method utilizing an image sensor, an auto white balance adjustment section, a change point detection section, and an electronic mark data generation section. The image sensor senses an image of an object and outputs an image signal corresponding to the image of the object. The auto white balance adjustment section automatically adjusts white balance of the image signal corresponding to a change of the image signal. The change point detection section detects a change point of the white balance corresponding to at least an adjustment value of the white balance while the image sensor is sensing the image of the object. The electronic mark data generation section generates electronic mark data for adjusted white balance based on time information of the change point detected by the change point detection section.
