Image generating apparatus, and image generating method and program

An image generating method comprising:

• storing a pixel value in a pixel value storing unit;
• storing, in an acquisition management data storing unit, acquisition management data that is used in common to a plurality of frame images and indicates whether or not to acquire a pixel value of each of pixels included in the frame images from the pixel value storing unit;
• determining, with regard to the plurality of frame images, based on the acquisition management data, whether or not to acquire the pixel value of each of the pixels included in the frame images from the pixel value storing unit;
• acquiring, from the pixel value storing unit, a pixel value of a pixel determined to have a pixel value acquired from the pixel value storing unit;
• and
• determining the pixel value of each of the pixels, wherein,
• in the storing the pixel value, the pixel value of the pixel determined to have the pixel value acquired from the pixel value storing unit is stored in the pixel value storing unit,
• in the determining the pixel value, with regard to the pixel determined to have the pixel value acquired from the pixel value storing unit, a pixel value acquired from the pixel value storing unit is determined as the pixel value of the pixel, and
• in the determining the pixel value, with regard to a pixel determined to have a pixel value not acquired from the pixel value storing unit, a predetermined value is determined as the pixel value of the pixel.

A non-transitory, computer readable storage medium containing a program, which when executed by a computer, causes the computer to conduct an image generating method by carrying out actions, comprising:

• storing a pixel value;
• storing acquisition management data that is used in common to a plurality of frame images and indicates whether or not to acquire a pixel value of each of pixels included in the frame images from the pixel value storing unit;
• determining, with regard to the plurality of frame images, based on the acquisition management data, whether or not to acquire the pixel value of each of the pixels included in the frame images from the pixel value storing unit;
• acquiring, from the pixel value storing unit, a pixel value of a pixel determined to have a pixel value acquired from the pixel value storing unit;
• and
• determining the pixel value of each of the pixels, wherein,
• in the storing the pixel value, the pixel value of the pixel determined to have the pixel value acquired from the pixel value storing unit is stored in the pixel value storing unit,
• in the determining the pixel value, with regard to the pixel determined to have the pixel value acquired from the pixel value storing unit, a pixel value acquired from the pixel value storing unit is determined as the pixel value of the pixel, and
• in the determining the pixel value, with regard to a pixel determined to have a pixel value not acquired from the pixel value storing unit, a predetermined value is determined as the pixel value of the pixel.
