Abstract

The invention provides an image signal processing apparatus, an image signal processing method and a program. The image signal processing apparatus includes multiple color support distortion correcting units receiving a color signal of a correction target image, performing image distortion correction of a color based on a lens distortion characteristic and generating a correction image supporting the color. Each of the multiple color support distortion correcting units performs processing of receiving a reference signal indicating a pixel position in an input image applied to calculate a pixel value of an output correction image, and setting a pixel value of the pixel position indicated by the reference signal in the input image as an output pixel value.

Description

technical field [0001] The present disclosure relates to an image signal processing device, an image signal processing method, and a program. Specifically, the present disclosure relates to an image signal processing device, an image signal processing method, and a program that perform processing of suppressing color shift caused in a display unit. Background technique [0002] A display device (ie, a head-mounted display (HMD)) mounted on the head to view images is widely known. The head-mounted display has an optical unit for each of the right and left eyes, and is configured to be able to control vision and hearing when used with an earphone. When configured so as to be completely isolated from the outside world when attached to the head, virtual reality is augmented while viewing and listening. Also, the head mounted display may reflect different images to right and left eyes, and may present a 3D image when images with parallax are displayed for the right and left eye...
