Abstract: Systems and methods for adaptive compression mode selection for memory buffers such as those used in or with a portable computing device (“PCD”) are presented. During operation of the PCD a first compression mode is selected for a buffer and the buffer is formatted to the first compression mode. Any access to the buffer by a component of the PCD, core of the PCD or software application running on the PCD is monitored. Based on the amount and/or type of access to the buffer, a second compression mode for the buffer is selected. The buffer is formatted to the second compression mode, providing a cost effective ability to adaptively format buffers based on the component(s), cores(s), and/or software application(s) accessing the buffers, and allowing for improving or optimizing bandwidth, memory footprint, resource conflict, power consumption, latency, and/or performance of component(s), core(s), or software application(s) accessing buffers as desired.

Abstract: A method, an apparatus, and a computer program product for processing touchscreen information are provided. The method may include receiving touchscreen data that includes node values representative of signals generated by a touchscreen panel, generating a first data frame including difference values, and transmitting the first data frame over a control data bus. Each of the difference values may be calculated as a difference between one of the node values and a different node-related value wherein the first data frame has a predefined size. The first data frame may be configured to permit a receiver of the first data frame to reconstruct the touchscreen data without information loss.

Abstract: Certain aspects relate to systems and techniques for compressing image data using pattern mode compression schemes. A pattern mode compression scheme can reduce the amount of data stored in a frame buffer to reduce power costs of an image display system. In some implementations, pattern mode compression can be suitable for compression of pixel blocks having a limited color palette with one or more pixels of a different foreground color, and a slope-enabled pattern compression can be suitable for compression of pixel blocks having a gradient. Input pixel values can be compared against a dynamically-populated, fixed size pattern entry database to determine whether pattern mode compression or slope-enabled pattern mode compression should be used to compress the image block.

Abstract: Methods and apparatus improve static region detection in an imaging pipeline. An imaging pipeline may perform detection of static regions of an image at multiple stages of the pipeline. For example, as static regions may be eliminated from further processing by the imaging pipeline, static region detection performed at an early stage of the pipeline may provide for maximized power savings. As images early in the pipeline may contain artifacts inhibiting detection of some static regions, additional static region detection may be performed after further image processing. For example, static region detection may be performed for a second time after some filtering is applied to images in the pipeline. Regions previously characterized as dynamic may be characterized as static later in the pipeline due to a reduction of noise for example provided by the filters, and differences between the static region detection at different positions within the imaging pipeline.

Abstract: Certain aspects relate to systems and techniques for compressing image data using mixed mode compression schemes. A mixed mode compression scheme can reduce the amount of data stored in a frame buffer to reduce power costs of an image display system. In some implementations, mixed mode compression can be suitable for compression of pixel blocks having one or two color channels exhibiting a relatively low variation in pixel intensity with the remaining channel or channels exhibiting a relatively high variation. The pixel values in each color channel of an RGB or YCoCg image can be analyzed to determine how many channels are a smooth component and how many channels are a variant component, and mixed mode compression can be selected and implemented based on the color channel analysis to adaptively and individually compress the color channels.

Abstract: Techniques and systems are provided for processing image data. For example, an image signal processor can obtain (e.g., from a host processor) a first setting change indicator value indicating a change in parameter settings of the image signal processor. The image signal processor can obtain an image frame from an image sensor, and can determine a second setting change indicator value from the image frame. The second setting change indicator value can be provided to the image sensor from the host processor. The second setting change indicator value indicates a change in parameter settings of the image sensor. The image signal processor can compare the first setting change indicator value to the second setting change indicator value, and can determine whether to process the image frame or to drop the image frame based on comparing the first setting change indicator value to the second setting change indicator value.
