摘要： PROBLEM TO BE SOLVED: To provide a video transmitting method that transmits a video picture encoded in a video format that reduces deterioration in image quality.SOLUTION: First, a decoding area upper limit is set as 1.5 HD (where HD=HDh×HDv, HDh: HD horizontal width, HDv: HD vertical width), and a gazing region size is set as HD as preconditions (step S1). Next, a tile size is set as a=HDh/x, and b=HDv/x (where x represents a real number), and x satisfying the decoding area upper limit is found (step S2). For example, it is determined that x=5 (step S3). With each tile set such that its horizontal size is HDh/5 and its vertical size is (1+(1/5))HDv, tile division and encoding are performed while vertically shifting the tile in units of HDv/5 (step S4). When the gazing region size is an HD size, a video picture in new tiles is transmitted each time the gazing region is moved vertically by HDv/5 and horizontally by HDh/5 (step S5).

A device characteristic calculating portion 107 calculates an input/output characteristic combining the image input unit 103 and the image output unit 104 based on the color of the image of the color chart and the color of the color chart. A device-characteristic correction-information calculating portion 108 calculates correction information for correcting a deviation of color information of the input/output characteristic because of the combination of the image input unit 103 and the image output unit 104 based on the input/output characteristic. An image conversion unit 109 converts a color image of the subject input from the image input unit 103 by using the correction information.
