Image transfer system, image transfer method, image reception apparatus, image transmission apparatus, and image pickup apparatus

An image transfer method, which is performed by an image transfer system including an image transmission unit that transmits an image and an image reception unit that receives the image transmitted from the image transmission unit, the image transfer method including the steps of:

• scaling down, by the image transmission unit, the image;
• transmitting, by the image transmission unit, the scaled-down image to the image reception unit;
• calculating, by the image reception unit, an angle between a line displayed in the image transmitted from the image transmission unit and a horizontal direction of the image in correspondence with pixels included in the image;
• scaling up, by the image reception unit, the image transmitted from the image transmission unit;
• and
• removing, by the image reception unit, an aliasing component of the scaled-up image based on the calculated angle.

An image reception apparatus for receiving an image from an image transmission apparatus, the image reception apparatus being configured to:

• calculate an angle between a line displayed in the image scaled down by the image transmission apparatus and a horizontal direction of the image in correspondence with pixels included in the image;
• scale up the image transmitted from the image transmission apparatus;
• and
• remove an aliasing component of the scaled-up image based on the calculated angle corresponding to the pixels.
