Hung - Web page: https://patentgrep.com/patent/US12764398B2 ## CPC - H04N 23/45: for generating image signals from two or more image sensors being of different type or operating in different modes, e.g. with a CMOS sensor for moving images in combination with a charge-coupled device [CCD] for still images - H04N: PICTORIAL COMMUNICATION, e.g. TELEVISION ## Abstract In some examples, an electronic device comprises a first camera to capture an image using a lens, a second camera to detect movement of an eye, and a controller coupled to the first and second cameras. The controller is to provide a signal combining a portion of the image captured by the first camera, and eye movement data indicating the movement of the eye detected by the second camera. ## Claims ### Claim 1 An electronic device, comprising: a first camera to capture an image using a lens; a second camera to detect movement of an eye; and a controller coupled to the first and second cameras, wherein the controller is to divide the image into a plurality of portions, wherein a quantity of the plurality of portions corresponds to a ratio of a capture frequency of the second camera to a frame rate of the first camera, and wherein the controller is to provide a signal combining: a portion of the image captured by the first camera from the plurality of portions; and eye movement data indicating the movement of the eye detected by the second camera. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the signal does not contain all of the image. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the electronic device includes a buffer to store the captured image. ### Claim 4 (depends on 1) The electronic device of claim 1, wherein a size of the portion of the image is based on the frame rate of the first camera and the capture frequency of the second camera. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the controller is to produce the signal consistent with any one of a Mobile Industry Processor Interface (MIPI) Camera Serial Interface (CSI), Camera Link, Universal Serial Bus (USB), and Institute of Electrical and Electronics Engineers (IEEE) 1394 specifications. ### Claim 6 (depends on 1) The electronic device of claim 1, wherein the first camera includes one of a complementary metal oxide semiconductor (CMOS) sensor or a charge-coupled device (CCD) sensor. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the first camera has a global shutter. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the controller is to, based on a change of the capture frequency of the second camera, adjust a quantity of a plurality of portions into which a second image captured by the first camera is divided. ### Claim 9 (depends on 1) The electronic device of claim 1, wherein each portion of the plurality of portions corresponds to an instance of a plurality of instances of capturing eye movement data by the second camera. ### Claim 10 (depends on 9) The electronic device of claim 9, wherein the controller is to: for each particular portion of the plurality of portions: combine the particular portion with the eye movement data captured in the instance corresponding to the particular portion to generate combined data; and provide the combined data on a hardware channel. ### Claim 11 A non-transitory, computer-readable medium storing executable code which, when executed by a controller, causes the controller to: receive an image captured by a first camera; store the image to a buffer; receive, from a second camera, eye movement data indicating movement of an eye; divide the image into a plurality of portions, wherein a quantity of the plurality of portions corresponds to a ratio of a capture frequency of the second camera to a frame rate of the first camera; and provide a signal combining the eye movement data and a portion, but not all, of the image from the plurality of portions. ### Claim 12 (depends on 11) The computer-readable medium of claim 11, wherein the first camera has a global shutter. ### Claim 13 (depends on 11) The computer-readable medium of claim 11, wherein a size of the portion of the image is based on the frame rate of the first camera and the capture frequency of the second camera. ### Claim 14 (depends on 11) The computer-readable medium of claim 11, wherein the first camera includes one of a complementary metal oxide semiconductor (CMOS) sensor or a charge-coupled device (CCD) sensor. ### Claim 15 (depends on 11) The computer-readable medium of claim 11, wherein the executable code, when executed by the controller, causes the controller to, based on a change of the capture frequency of the second camera, adjust a quantity of a plurality of portions into which a second image captured by the first camera is divided. ### Claim 16 (depends on 11) The computer-readable medium of claim 11, wherein each portion of the plurality of portions corresponds to an instance of a plurality of instances of capturing eye movement data by the second camera. ### Claim 17 An electronic device, comprising: a camera with a rolling shutter to capture a plurality of portions collectively representing an image; a biometric sensor to capture biometric data, wherein a quantity of the plurality of portions corresponds to a ratio of a capture frequency of the biometric sensor to a frame rate of the camera; and a controller coupled to the camera and the biometric sensor, the controller to: receive a portion of the image from the plurality of portions, and the biometric data; and provide a signal combining the portion of the image and the biometric data. ### Claim 18 (depends on 17) The electronic device of claim 17, comprising a buffer to store the portion of the image for subsequent access. ### Claim 19 (depends on 17) The electronic device of claim 17, wherein the controller is to produce the signal consistent with any one of a Mobile Industry Processor Interface (MIPI) Camera Serial Interface (CSI), Camera Link, Universal Serial Bus (USB), and Institute of Electrical and Electronics Engineers (IEEE) 1394 specifications. ### Claim 20 (depends on 17) The electronic device of claim 17, wherein each portion of the plurality of portions corresponds to an instance of a plurality of instances of capturing biometric data by the biometric sensor.
