Abstract: The techniques of this disclosure are applicable to backlight display devices. For such devices, the backlight may have different backlight intensity settings in order to promote power conservation. The techniques of this disclosure may apply different adjustments to the display, depending on the backlight intensity setting. In one example, different color correction matrices may be applied for different backlight settings in order to achieve desirable adjustments in the device at the different backlight settings. The adjustments described herein may address chrominance shifts due to different backlight settings as well as cross-talk between color channels. The techniques may also be applicable to organic light emitting diode (OLED) displays that have different luminance settings, and some described techniques may be applicable to displays that have static or fixed luminance output.

Abstract: An apparatus and method are disclosed wherein a depth map is generated using a single camera (e.g., single lens of a camera) and multiple images are captured by the camera. In one example, a single digital camera is used to capture a set of images corresponding to a set of lens positions based on lens position data. In this example, the lens position data may be either uniform or nonuniform lens position data. The method and apparatus determines focus metric information for each of a plurality of regions of interest in each image of a set. A determination is made of a best lens position for each of the regions of interest based on the focus metric information from the images in the set and are stored as data in a depth map. Image generation operations are then performed based on the generated depth map, such as determining whether or not to use a flash to capture a final image, to determine a type of color operation to be performed on the final image, or any other suitable image generation operation. In one example, the depth map is generated by selecting a best focus metric among the various images that were captured for a particular region of interest. Once the depth map is generated using data from the multiple images, depth map based control logic then determines how to use the depth map to effect an image processing operation. Among other advantages, multiple cameras need not be employed nor do external light sensors need be employed to generate a depth map for use in image processing operations. Other advantages will be recognized by those of ordinary skill in the art.

Abstract: An n bit D/A decoder is formed using P-type and N-type transistor switches, instead of convention CMOS switches. Each P-type and N-type switch may be formed of fewer transistors than those used to form a CMOS switch, thereby reducing the overall transistor count. The decoder may be used to decode digital values to non-linear GAMMA corrected analog output voltages.

Abstract: To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.

Abstract: Described herein are methods, systems and apparatus to improve imaging sensor production yields. In one method, a stereoscopic image sensor pair is provided from a manufacturing line. One or more images of a correction pattern are captured by the image sensor pair. Correction angles of the sensor pair are determined based on the images of the correction pattern. The correction angles of the sensor pair are represented graphically in a three dimensional space. Analysis of the graphical representation of the correction angles through statistical processing results in a set of production correction parameters that may be input into a manufacturing line to improve sensor pair yields.

Abstract: A graphics multi-media integrated circuit (GMIC) is connected to a host processor over two serial links: a half duplex bi-directional serial link which accords to a protocol defined for a display serial interface, and a uni-directional serial link which accords to a compatible protocol defined for a camera serial interface. The GMIC receives packets according to the protocol from the host over the half duplex bi-directional serial link and processes these packets. The GMIC sends packets according to the protocol to the host over the uni-directional serial link. A packet from the host can request a processing operation by the GMIC or can initiate a memory operation at the memory of the GMIC. The GMIC can also send packets to the host to initiate a memory operation at the memory of the host. The GMIC may be connected to a display over a bi-directional serial link according to the display serial interface protocol and to a camera over a uni-directional serial link and a bi-directional control link according to the camera serial interface so that the host controls the display and camera indirectly through the GMIC.
