Documentation Examples Functions Blocks Videos Answers Main Content Count active dimensions of pixel streamDescriptionThe HV Counter block analyzes a video stream and returns the current count of lines per frame and pixels per line. The block also delays control signals of the pixel stream to correspond with the count result. Use this block for algorithms that use the location of a pixel within a frame or region of interest.This waveform shows the pixel-stream control signals and resulting counter outputs for the first two lines of a video frame that has 10 pixels per line. The HV Counter block has a latency of two cycles to return the current counter values.ExamplesPortsThis block uses a bus for frame control signals associated with each pixel of a pixel stream. This interface enables the block to operate independently of image size and format. All Vision HDL Toolbox™ blocks use the same streaming interface. The block accepts and returns a bus containing five control signals. The control signals indicate the validity of each pixel and its location in the frame.

Actual read/writes.Many versions ago, I recognized that some games rely on this register for timing (since its increments are deterministic). My previous implementation was partial. All games tested were playable, but some exhibited unexpected behaviour.A game named Sanxion uses a text fade effect whereby the text disappears pixel-by-pixel, randomly. However, when run in zxian, the fade effect occurred in strips, rather than randomly. I investigated this by analyzing CPU instruction execution counts. This led me to a LD A, R instruction, which was executed just enough times (coinciding with the fade animation) to be interesting.Following the LD A, R, in version 24 I've improved the implementation. Specifically, R is correctly incremented as a 7bit counter, and not an 8bit counter. That is, it now goes from x1111111 to x0000000, keeping bit 7 unchanged.The error modes of games were noteworthy. They exhibited strange and interesting effects when R was not incremented correctly. Here's a summary, categorized by R incrementing strategy used.R not incremented - Games like Defender of the Crown no longer animates fighting soldiers.R incremented as 8bit counter, normal frequency - Ping Pong's paddle graphics are corrupted, and gameplay timing is off.R incremented as 8bit counter, lower frequency - Robin of the Wood's soldiers can disappear or be corrupted; Robin's hits make no sounds; menu sounds are bad.R incremented 7bit counter, normal frequency - No side effects observed.Development screenshotsPixel Counter Sensor Or Something?

The Basler Ace 2 a2A2448-23gcPRO GigE Vision camera offers great value with advanced features.Using a Power over Ethernet (“PoE”) configuration, a single cable may be used to apply camera power and to transfer data between this camera and a PC, keeping cable runs to a minimum. An auxiliary connector is provided for terminating the input and output signal – there is one of each. The input may be configured to trigger image acquisition, reset the frame counter, or reset the software trigger count. The output may be configured to indicate acquisition trigger wait, exposure active, flash window, or timer active. Or the output may be controlled via a PC. The auxiliary connector may be used to power the camera if PoE is not available.The Basler ace 2 provides a full set of features to address a wide range of applications. Pixel data can be output in 8 or 12 bit depth. You may adjust the camera’s black level, gain, area of interest, input debounce, and trigger delay. It features automatic exposure control, pixel binning, horizontal image mirroring, event reporting, sending of test images, and a programmable lookup table. There are also “chunk” features that include a frame counter, time stamp, trigger input counter, and CRC checksum calculator. Note that not all features may be available when using third-party software.Because this camera is GigE Vision and GenICam compliant, there are many third party software applications and API’s that are compatible. Basler offers their royalty-free Pylon SDK with support for most operating systems.The Basler ace 2 is available in "Basic" and "Pro" versions. Both feature a status LED on the back, a removable IR cut filter, and robust M8 I/O connector. This is the Pro version, which adds:> Compression Beyond can reduce required bandwidth and/or increase the frame rate over GigE, using either lossless or lossy compression.> Pixel Beyond for uncomplicated "virtual" adjustment of sensor pixel size and characteristics.> PGI features work directly inside the camera to deliver the best image quality without reducing frame rate or increasing computer load.> Support for parameter sequencers to rapidly cycle certain parameter values, such as exposure.Note that Compression Beyond requires Pylon (Viewer, API, or GenTL Producer) to decompress images. The compression ratio will vary with camera configuration and image content.. Pixel Counter. The pixel counter shows the number of pixels in an area of the image.
