In a low resolution mode, some pixels of the readers image sensor array are clock out at normal clock out speed sufficient to develop electrical signals accurately reflecting the intensity of light at the respective pixel positions, while other pixels of the array are either not clocked out or are clocked out at a higher clock out rate which may be insufficient to allow development of electrical signals that accurately represent light incident on the image sensor's sensor array but which nevertheless, results in a reduction of the overall frame clock out rate of the frame of image data. An optical reader according to the invention operates in a low resolution frame clock out mode to capture a low resolution parameter determining frame of image data at high speed, reads pixel data from the parameter determination frame to determine an operation parameter based on actual illumination conditions, then utilizes the operation parameter in operating an optical reader.
SUMMARY OF THE INVENTION According to its major aspects and broadly stated, the present invention is a method for controlling an optical reader to reduce the reader's parameter determination delay. According to the invention, an image sensor is adapted to clock out image data from an image sensor according to two modes of operation, a ��low resolution�� clock out mode of operation and a ��normal resolution�� clock out mode of operation.
In a low resolution mode, some pixels of the reader's image sensor pixel array are clocked out at a normal clock out speed sufficient to develop electrical signals that accurately represent the intensity of light incident on the pixel array, while other pixels of the array are either not clocked out or are clocked out at a higher clock out rate which is insufficient to allow development of electrical signals that accurately represent the intensity of light at the respective pixels but which nevertheless, result in an increase in the overall frame clock out rate of the frame of image data. In a normal resolution mode of operation the image sensor is caused to clock out electrical signals corresponding to each pixel of the array at a constant ��normal mode�� speed which is a speed sufficient to ensure that the electrical signal corresponding to each pixel accurately represents the intensity of light incident on the pixel.
By contrast, an image sensor of the present invention is made to operate under two major frame capture modes, a ��low resolution�� frame clock out mode and a ��normal resolution�� frame clock out mode. In a ��low resolution�� mode of operation, an image sensor according to the invention is operated to clock out electrical signals corresponding to some pixels of an image sensor array at a high clock out rate and other pixels of the image sensor at a normal clock out rate. Clocking out a portion of the electrical signals using a faster than normal clock out rate results in a reduction in the overall frame clock out time while clocking out a portion of the signals at a normal clock out rate enables the generation of pixel data sufficient to enable determination of parameter settings for use in subsequent frame captures. In a ��normal resolution�� mode of operation the image sensor is operated to clock out electrical signals corresponding to pixels of the array using a single uniform clock out speed as in prior art readers. The low resolution mode of operation may also be carried out by clocking out electrical signals corresponding to only a portion of a frame's pixels and not clocking out electrical signals corresponding to the remaining pixels.
A reader configured in accordance with the invention clocks out and captures in a memory storage location at least one parameter determination frame of image data in a ��low resolution�� frame capture mode, reads pixels of the parameter determination frame in establishing at least one operation parameter that is based on actual illumination conditions, utilizes the determined operation parameter in clocking out a subsequent frame of image data in a ��normal resolution mode,�� then captures and subjects the frame of image data clocked out utilizing the operation parameter to image data searching, decoding, and/or recognition processing. The reader may be adapted to decode a decodable symbol represented in a frame of image data developed utilizing a determined operating parameter.
Processor 44 is preferably devoted primarily to controlling the image acquisition process, the A/D conversion process and the storage of image data, including the ability to access memories 46 and 47 via a DMA channel. Processor 44 may also perform many timing and communication operations. Processor 44 may, for example, control the illumination of LEDs 22, the timing of image sensor 32 and an analog-to-digital (A/D) converter 36, the transmission and reception of data to and from a processor external to reader 10, through an RS-232, a network such as an Ethernet, a serial bus such as USB, a wireless communication link (or other) compatible I/O interface 37. Processor 44 may also control the outputting of user perceptible data via an output device 38, such as a beeper, a good read LED and/or a display monitor which may be provided by a liquid crystal display such as display 82. Control of output, display and I/O functions may also be shared between processors 42 and 44, as suggested by bus driver I/O and output/display devices 37�� and 38�� or may be duplicated, as suggested by microprocessor serial I/O ports 42A and 42B and I/O and display devices 37″ and 38��. As explained earlier, the specifics of this division of labor is of no significance to the present invention.
In a ��low resolution�� frame clock out mode of the invention, however, control circuit 40 causes image sensor 32 to clock out electrical signals corresponding to the pixels of the array at least two speeds during a single frame capture period. During a single frame clock out period, control circuit 40 controls image sensor 32 so that some pixels are clocked out at normal clock out rate sufficient to develop electrical signals accurately representing the intensity of light at the respective pixel positions, while other pixels are either not clocked out or are clocked out at a clock out rate which may be insufficient to allow development of electrical signals that accurately represent the intensity of light at the respective pixels but which nevertheless results in a reduction of the overall frame clock out time of the frame of image data being clocked out.
FIG. 1 a shows a schematic diagram of an exemplary image map frame that is clocked out according to the low resolution frame clock out mode of the invention and then captured into memory 45. The image map is divided into ��zones�� of valid data and invalid data. Valid zones 84 shown are rows of pixels that are clocked out at a normal clock out speed while invalid zones 86 shown are rows of pixels that are clocked out at a faster clock out speed, which is normally (but not necessarily) a speed insufficient to allow development of electrical signals accurately representing the intensity of light at a pixel.
Using CMOS fabrication techniques, image sensors are readily made so that electrical signals corresponding to certain pixels of a sensor can be selectively clocked out without clocking out electrical signals corresponding to remaining pixels of the sensor. CMOS image sensors are available from such manufacturers as Symagery, Pixel Cam, Omni Vision, Sharp, Natural Semiconductor, Toshiba, Hewlett-Packard and Mitsubishi. Further aspects of a partial frame clock out mode are described in commonly assigned application Ser. No. 09/766,806 entitled ��Optical Reader Having Partial Operating Mode�� now U.S. Pat. No. 6,637,658 filed concurrently herewith and Frame incorporated herein by reference.
The invention is also conveniently realized with use of an image sensor having an image sensor discharge function. Image sensors having a discharge function are typically adapted to receive a discharge clock out signal which when active results in all pixels of a frame being read out at a high clock out rate insufficient to allow development of electrical signals. In presently available readers having a directional function, a control circuit sets the discharge clocking signal to an active state while clocking out an initial ��discharge period�� frame of image data immediately after reception of a trigger actuation. This initial discharge process removes any residual charges built up on image sensor 32 prior to capturing a first frame including valid pixel data.
Referring to time line 92 corresponding a prior art reader it can be seen that a substantial parameter determination delay is present without use of a low resolution frame capture mode according to the invention. At time T0, control circuit 40 activates a frame discharge control signal so that residual charges built up in the storage locations of buffer memory 32 b are eliminated or ��cleaned�� during clock out period CPO.
