2024-05-03libcamera: libipa: camera_sensor: Add Sony IMX283 sensor propertiesKieran Bingham
Provide the IMX283 camera sensor properties and registration with libipa for the gain code helpers. The test patterns exposed by the IMX283 do not map well to the current set of test pattern controls supplied by libcamera. These are left intentionally unimplemented.

2024-04-20android: camera_device: Always clear descriptors_ in stop()Anle Pan
When flush() is called and then a new stream configuration is set, the descriptors_ queue might have a chance to be not cleared in stop(), as the Camera is already in Stopped state. This will prevent further requests from being completed in sendCaptureResults() as the descriptors_ queue is not empty. To fix the issue, clear the descriptors_ even if the Camera State is Stopped. As a drawback the libcamera::Camera::stop() function might be called twice, but this is allowed by the Camera state machine, and the second call is guaranteed to be a nop.

2024-04-16libcamera: software_isp: Apply black level compensationMilan Zamazal
Black may not be represented as 0 pixel value for given hardware, it may be higher. If this is not compensated then various problems may occur such as low contrast or suboptimal exposure. The black pixel value can be either retrieved from a tuning file for the given hardware, or automatically on the fly. The former is the right and correct method, while the latter can be used when a tuning file is not available for the given hardware. Since there is currently no support for tuning files in software ISP, the automatic, hardware independent way, is always used. Support for tuning files should be added in future but it will require more work than this patch. The patch looks at the image histogram and assumes that black starts when pixel values start occurring on the left. A certain amount of the darkest pixels is ignored; it doesn't matter whether they represent various kinds of noise or are real, they are better to omit in any case to make the image looking better. It also doesn't matter whether the darkest pixels occur around the supposed black level or are spread between 0 and the black level, the difference is not important. An arbitrary threshold of 2% darkest pixels is applied; there is no magic about that value. The patch assumes that the black values for different colors are the same and doesn't attempt any other non-primitive enhancements. It cannot completely replace tuning files and simplicity, while providing visible benefit, is its goal. Anything more sophisticated is left for future patches. A possible cheap enhancement, if needed, could be setting exposure + gain to minimum values temporarily, before setting the black level. In theory, the black level should be fixed but it may not be reached in all images. For this reason, the patch updates black level only if the observed value is lower than the current one; it should be never increased. The purpose of the patch is to compensate for hardware properties. General image contrast enhancements are out of scope of this patch. Stats are still gathered as an uncorrected histogram, to avoid any confusion and to represent the raw image data. Exposure must be determined after the black level correction -- it has no influence on the sub-black area and must be correct after applying the black level correction. The granularity of the histogram is increased from 16 to 64 to provide a better precision (there is no theory behind either of those numbers).

For now, only BGR888 output format, which is the simplest one to use, is supported but nothing prevents adding support for other output formats if needed. Nevertheless, they would typically need byte reordering or other conversions for PPM file format.

2024-03-20apps: lc-compliance: Check that requests complete successfullyNícolas F. R. A. Prado
When a request fails to queue it is completed but with its status set to RequestCancelled. Add a check in the requestComplete callback to make sure that the request was completed successfully. For the SimpleCaptureUnbalanced test we need to do this check only if the capture isn't over yet, otherwise the few extra requests that get cancelled at the end, which is the normal behavior, will make the test fail.

This is incorrect, as the V4L2 API provides such a flag. Use it to replace the workaround.

The CameraSensor class has grown a lot since its creation, with many functions added for different types of purposes. They are not grouped by categories in the class definition, generating confusion when reading the header file.

The CameraSensor::updateControlInfo() function is a wrapper around the same function of the V4L2Subdevice class. It was meant to be called by pipeline handlers that modify the sensor configuration directly, bypassing the CameraSensor::setFormat() function. This never happened, and the function is called once only, internally to the CameraSensor class. No external users are foreseen, drop the function and call V4L2Subdevice::updateControlInfo() directly.

2024-03-15libcamera: v4l2_subdevice: Add V4L2Subdevice::Route structureLaurent Pinchart
The V4L2Subdevice class deals with streams in two places: - In routing tables, streams as expressed as a pad number and a stream number in a v4l2_subdev_route instance. - In the format and selection get and set functions, streams as expressed using the Stream structure, which binds the pad number and stream number. Expressing streams in different ways requires pipeline handlers and other helpers to convert between the two representations. This isn't much of an issue yet as libcamera has little stream-aware code, but it is expected to increasingly become a burden. To simplify the API, introduce a V4L2Subdevice::Route structure that mimicks the kernel v4l2_subdev_route structure but represents streams as V4L2Subdevice::Stream instances. This will improve seamless integration of routes, formats and selection rectangles.

2024-03-15libcamera: v4l2_subdevice: Replace Routing::toString() with operator<<()Laurent Pinchart
The main (and only at the moment) use case for the Routing::toString() function is to print a representation of the routing table in a log message. The function is implemented using an std::stringstream, and the returned std::string is then inserted into an std::ostream. This is inefficient. Replace the function with a specialization of the operator<<() and use it in the caller.

Extend the V4L2Subdevice API with stream support for the functions that get and set formats and selection rectangles. Add a Stream structure to identify a subdev pad and stream, and use it to extend the V4L2Subdevice functions that get and set formats and selection rectangles with stream support. To preserve the existing pad-based API, implement overloaded functions that wrap the new stream-based API. This allows callers that are not stream-aware to use a simpler pad-based API, instead of having to explicitly set the stream number to 0 in all API calls.
