Image sensing apparatus and method generating electronic mark data based on white balance detections

An image sensing method, comprising:

• sensing an image of an object and outputting an image signal corresponding to the image of the object;
• automatically adjusting white balance of the image signal corresponding to a change of the image signal;
• detecting a change point of the white balance corresponding to at least an adjustment value of the white balance while the image of the object is being sensed at the image sensing;
• generating electronic mark data for adjusted white balance based on time information of the change point detected at the detecting a change point;
• and
• recording the image signal to a recording medium and recording the electronic mark data to a recording medium, correlating in time the electronic mark data to points in the image signal when the electronic mark data is recorded.
