A circuit device includes a storing section configured to store a rendering image and a warp processing section. The warp processing section includes a coordinate converting section, a coordinate-address converting section, and an output section. The coordinate converting section converts, with coordinate conversion based on warp parameters and rotation correction parameters, an output coordinate, which is a coordinate on a display image, into an input coordinate, which is a coordinate on the rendering image. The coordinate-address converting section converts the input coordinate into a read address of the storing section. The output section reads out pixel data of the rendering image from the read address of the storing section and outputs, based on the read-out pixel data, pixel data in the output coordinate of the display image.

Circuit device, display system, and electronic apparatus

A circuit apparatus includes a memory unit and a warp processing unit. The memory unit stores a warp object image. The warp processing unit performs warp processing on the warp object image and generates a display image displayed in a display area. The warp processing unit performs the warp processing on an image of a first view object of the warp object image based on a first warp parameter for vibration correction and distortion correction. Further, the warp processing unit performs the warp processing on an image of a second view object of the warp object image based on a second warp parameter for the distortion correction.

Circuit apparatus, display system, and image processing method

A circuit device includes a storage circuit, an image conversion circuit, and an error detection circuit. The storage circuit stores received first image data. The image conversion circuit executes an image conversion by a coordinate conversion on the first image data by outputting a reference coordinate indicating a pixel position on the first image data and outputting second image data based on pixel data that is read from the storage circuit based on the output reference coordinate. The error detection circuit executes error detection on the reference coordinate output by the image conversion circuit.

Circuit device and error detection method

A control system includes: an image processing circuit; a first error detection circuit configured to perform first error detection on second image data; a first error code value generation circuit configured to generate a first error code value based on the second image data; a transmission interface circuit; a reception interface circuit; a second error code value generation circuit configured to generate a second error code value based on the second image data; a second error detection circuit configured to perform second error detection based on the first error code value and the second error code value; and a control circuit configured to output a control signal when an error is detected in at least one of the first error detection and the second error detection.
