Abstract: 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.

Abstract: An image dividing circuit includes an input interface circuit that receives input image data configured by a total number of horizontal pixels HT, an image data dividing circuit that divides the input image data into first to n-th output image data, and an output interface circuit that includes output circuits for first to n-th channels that output the first to n-th output image data. The parameter n is an integer greater than or equal to 3, and the parameter HT is not an integer multiple of the parameter n. An output circuit for an i-th channel outputs i-th output image data in which at least one of the total number of horizontal pixels and the total number of vertical lines in the i-th channel has been variably adjusted. The parameter i is an integer greater than or equal to 1 but smaller than or equal to n.

Abstract: 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.

Abstract: A circuit device includes an image processing circuit and a comparison circuit. The image processing circuit performs a first mapping process and a first rotation process on an input image to generate an image for a head up display. The image processing circuit performs, on an image, a second mapping process that is a reverse mapping process of the first mapping process and a second rotation process that is a reverse rotation process of the first rotation process to generate an image. The comparison circuit performs a comparison between the image and the image and outputs a result of the comparison as information for detecting an error in the image.

Abstract: A circuit device (100) includes a coordinate transform circuit (20) and a mapping processing circuit (30). The coordinate transform circuit (20) performs coordinate transformation from an input coordinate (IXY1) to an output coordinate (QXY1). The mapping processing circuit (30) generates a second image (IMG2) to be displayed in a display panel for displaying an image in a curved screen display by performing mapping processing on a first image (IMG1) that is input based on the output coordinate (QXY1). The coordinate transform circuit (20) performs the coordinate transformation from the input coordinate (IXY1) to the output coordinate (QXY1) by performing computation processing using a second or more order polynomial representing the coordinate transformation.

Abstract: A circuit device 100 includes an error detection circuit 110 and a processing circuit 120. The error detection circuit 110 obtains a glare index value, which is an index value indicating glare of a head-up display, based on image data IMD for head-up display. The error detection circuit 110 determines whether or not a glare index value has exceeded a first threshold value, and when the glare index value exceeds the first threshold value, detects occurrence of a first glare error. When occurrence of a first glare error is detected, the processing circuit 120 performs processing corresponding to the first glare error.
