Abstract
A circuit device includes an image splitting circuit, a first output terminal group to an n-th output terminal group, and a switching circuit. The image splitting circuit splits input image data into first image data and second image data. The switching circuit allocates the first image data to any i output terminal groups among the first output terminal group to the n-th output terminal group, and outputs the first image data from the i output terminal groups to a first display. The switching circuit allocates the second image data to any j output terminal groups among output terminal groups obtained by excluding the i output terminal groups from the first output terminal group to the n-th output terminal group, and outputs the second image data from the j output terminal groups to a second display.
Claims14
A circuit device comprising:
- an image splitting circuit configured to split input image data into first image data to be displayed on a first display and second image data to be displayed on a second display;
- a first output terminal group to an n-th output terminal group, n being an integer of 3 or more;
- and
- a switching circuit configured to allocate the first image data and the second image data to the first output terminal group to the n-th output terminal group, wherein
- the switching circuit is configured to:
- allocate the first image data to any i output terminal groups among the first output terminal group to the n-th output terminal group, and output the first image data from the i output terminal groups to the first display, i being an integer of 1 or more and n−1 or less;
- allocate the second image data to any j output terminal groups among output terminal groups obtained by excluding the i output terminal groups from the first output terminal group to the n-th output terminal group, and output the second image data from the j output terminal groups to the second display, j being an integer of 1 or more and n-i or less;
- split the first image data into first channel data to i-th channel data;
- allocate the first channel data to the i-th channel data of the first image data to a first output terminal group to an i-th output terminal group among the i output terminal groups in a first mode;
- and
- allocate the i-th channel data to the first channel data of the first image data to the first output terminal group to the i-th output terminal group among the i output terminal groups in a second mode,
