These functions are described in detail below. First, the various modes are shown below. These modes are switched using control data D13 to D14 SMD. D14 D13 0 0 0 1 1 0 1 1 Description of operation Electronic shutter stopped mode High-speed/low-speed shutter mode HTSG control mode The electronic shutter data is expressed as shown in the table below using D18 to D27 SHD as an example. MSB D27 0 LSB D26 D25 D24 1 1 1 1 C D23 D22 D21 D20 0 0 0 0 3 D19 D18 1 1 SHD is expressed as 1C3h . [Electronic shutter stopped mode] During this mode, all shutter data items are invalid. SUB is not output in this mode, so the shutter speed is the accumulation time for one field. [High-speed/low-speed shutter mode] During this mode, the shutter data items have the following meanings. Symbol Data Description SVD D10 to D17 Number of vertical periods specification (00h SVD FFh) SHD D18 to D27 Number of horizontal periods specification (000h SHD 3FFh) SPL D28 to D35 Vertical period specification for high-speed shutter operation (00h SPL FFh) The period during which SVD and SHD are specified together is the shutter speed. Concretely, when specifying high-speed shutter, SVD is set to "00h". (See the figure.) During low-speed shutter, or in other words when SVD is set to "01h" or higher, the serial interface data is not loaded until this period is finished. The vertical period indicated here corresponds to one field in each drive mode. In addition, the number of horizontal periods applied to SHD can be considered as (number of SUB pulses - 1). Note) The bit data definition area is assured in terms of the CXD2470R functions, and does not assure the CCD characteristics. - 19 - CXD2470R VDI SVD SHD V1A SUB WEN SMD 01 01 SVD 02h 00h SHD 10Fh 050h Further, SPL can be used during this mode to specify the SUB output at the desired vertical period during the low-speed shutter period. In the case below, SUB is output based on SHD at the SPL vertical period out of (SVD + 1) vertical periods. SPL VDI SVD SHD V1A SUB WEN SMD 10 01 SPL 01h 00h SVD 02h 00h SHD 10Fh 0A3h Incidentally, SPL is counted as "00h", "01h", "02h" and so on in conformance with SVD. Using this function it is possible to achieve smooth exposure time transitions when changing from low-speed shutter to high-speed shutter or vice-versa. - 20 - CXD2470R [HTSG control mode] During this mode, all shutter data items are invalid. The V1A/B and V3A/B ternary level outputs are stopped, so the shutter speed is the value obtained by adding the shutter speed specified in the preceding vertical period to the vertical period during which these readout pulses are stopped as shown in the figure.
