Continuous Mode image capture & output
Snapshot Mode image capture & output
The state diagram of M64285K is shown above. The sequence to control M64285K is explained below. (1) Reset all the registers and counters. RESET is set to "L" (asynchronous to CLK). Reset state is in the Standby state. (2) Set the contents of the registers. There are 16 sets of registers, consisting of 4 bits each. The input data is composed of 8 bits. The leading 4 bits are for address and the following 4 bits are for data. The input data is latched at the rising edge of SCLK. When LOAD goes "H", the contents of the register become fixed at the rising edge of CLK. (3) Start image capture. After the contents of all the registers are fixed, START is asserted in synchronous with the rising edge of CLK. Then the control counters are reset to the initial value specified by the registers, and the image capture sequence starts. After the accumulation time defined by the registers 4 ~ 7, the analog image signals are outputted serially. The STRB pulse is outputted in synchronous with the above. The number of active data on one frame is 1024 for the 2D image, 64 for the projection image, and 1 for the pixel average data; the number of data outputted in each modes is fixed by the combination of the above. When this chip finishes outputting the defined number of data, in the snapshot modes (MD3=1), it automatically falls into the Standby state. In the continuous modes (MD3=0), once the image capture sequence starts, this chip carries on outputting the image data, unless START is asserted again or STOP bit is set to "H" to force the chip into the Standby state. The contents of the registers can be changed in the Standby state. When START is asserted in the standby state or in the continuous image capture sequence, the control counters are, again, reset to the initial value specified by the registers, and the image capture sequence starts. If the register contents are changed before asserting START, M64285K outputs the data in a different mode. In the continuous output modes, register No. 2 including the STOP bit is the only register that is allowed to be set.

STOP bit forces the chip into Standby state from the continuous image capture state. When "STOP = 1" is set, image capture sequence stops and the chip falls into the Standby state, with preserving the register contents. Afterwards, STOP bit is automatically reset to "0". This bit is allowed to be set in the continuous output modes. M64285K can output the inverted STRB signal. If needed, set STINV to "1", else, set it to "0". M64285K outputs the optical black level before outputting the image data. BSTRB selects whether to output the STRB pulse at the optical black level output timing. If needed to be ON, set BSTRB to "1", else, set it to "0". POWSV selects the Power Save state, in which power consumption is suppressed by reducing the AMP current to be 1/10 while the chip is not outputting the analog data (ex.: just after RESET, or in the accumulation period). The default state for POWSV is 1 (ON). Besides, if the STDBY bit is 1, power consumption is further suppressed by completely cutting the AMP current while the chip is in the Standby or Halt state.

Projection Image Continuous Mode ( MD = 0100 ) Right figure shows the projection operation. Two dimensional (2D) input image pattern is illuminating the image plane, and all the pixel data in each columns and each rows are taken average followed by 32 column projection data output and 32 row projection data output in sequence. It is a kind of Image compression, in which 1024 bytes output data in the 2D form is compressed to 64 bytes data. Therefore the readout time and the processing cost in the subsequent part is widely reduced. Also, the data range of projection is the same as the 2D image data.

In Offset Subtraction this case, by only setting the Gain higher, the output easily exceed the A/D conversion range. M64285K is able to subtract some offset from the data before amplification. By means of this function, as shown in the figure, it becomes possible to obtain high contrast image in the optimum range. OFST register decides the magnitude of this offset. The output data is obtained after subtracting the value in the table below from the image data, under the standard gain condition (0 dB). The offset value to be subtracted is proportional to the gain. If there is no need of subtracting offset, as in the case of capturing normal image in full range, set the OFST Register 00000.

13. Operational Timing 13.1. Chip Reset * Register Set * Image Capture Start The registers are set after resetting the chip. The timing chart below shows the operation up to the image capture. RESET is done asynchronous with CLK. The input data, SIN, which is used to set registers is inputted serially asynchronous with CLK and latched to the registers by the LOAD signal. Detailed timing of SIN and LOAD is given in "13.2. Register Set". After the contents of all registers have been decided, START is inputted in synchronous with the rise of CLK. Then, the counter used for controlling purposes is reset to the initial value which is specified by the register. Now, the image capture starts. If the period of LOAD or START is longer than 2 CLKs, the valid timing is the first CLK rise for LOAD, and the last CLK rise for START.

13.3. Image Data Output Image data is outputted from VOUT serially. Simultaneously, the STRB signal is outputted as the timing reference for A/D conversion. The STRB is basically in synchronous with the rising edge of CLK, and its pulse width ("H" level) is 4. However the pulse width ("H" level) becomes 2 only when DOC = 4. At the timing of outputting the optical black pixel (OBP), STRB pulse is outputted only in the case BSTRB = 1. OBP timing is shown by the hatched STRB pulse or the hatched box. 13.3.1. 2D Image : Continuous Output * MD = 0000
