Image encoding device and image encoding method with distance information
View Patent ↗An image encoding device includes a single image pickup unit generating image data by shooting a subject, an image compression unit generating digital image data by encoding the image data, a distance measuring unit measuring a distance to the subject during the shooting, and a multiplexing unit generating multiplexed data based on the digital image data and the measured distance by multiplexing distance data indicating the distance to a subject of each of given pixel blocks of the digital image data onto the digital image data.
1. An image encoding device comprising:
a single image pickup unit configured to generate image data by shooting at least one subject;
an image compression unit configured to generate digital image data by compressing the generated image data;
a distance measuring unit configured to measure a distance to the subject when the image pickup unit performs the shooting;
a multiplexing unit configured to generate multiplexed data based on the digital image data and the measured distance by appending, in a header part of the digital image data, distance data indicating a distance to a subject of each of given pixel blocks of the digital image data to the digital image data; and
an image conversion unit configured to generate right-eye image data and left-eye image data in accordance with a parallax occurring at a viewpoint defined during the shooting by horizontally moving each subject data included in the digital image data in a right direction and a left direction based on the distance data obtained for each of the given pixel blocks by using the generated multiplexed data.
2. The image encoding device according to claim 1 , wherein the image conversion unit calculates an amount of the movement of the each subject in the right direction and the left direction based on data of a distance to a background of the digital image data and data of a distance to the subject.
3. An image encoding method comprising the steps of:
generating image data by shooting at least one subject by using a single image pickup unit;
generating digital image data by compressing the generated image data;
measuring a distance to the subject when the image pickup unit performs the shooting at the image-data generating step;
appending, in a header part of the digital image data, distance data indicating a distance to a subject of each of given pixel blocks of the digital image data to the digital image data based on the digital image data encoded and generated at the digital-image-data generating step and the distance measured at the measuring step; and
generating right-eye image data and left-eye image data in accordance with a parallax occurring at a viewpoint defined during the shooting by horizontally moving each subject data included in the digital image data in a right direction and a left direction based on the appended distance data obtained for each of the given pixel blocks.
