摘要： A plurality of setting data stored in a serial register 11 and externally supplied replacement data are inputted into selectors 12. Either of the setting or replacement data is provided to the respective one of the setting inputs S.sub.1 -S.sub.n in a digital signal processing unit 10. Each of the selectors 12 usually selects the setting data. When a selector 12 is specified by a decoder 13 based on address data, it only selects the replacement data. When the replacement and address data are suitably set, the computation condition of the digital signal processing unit 10 can be partially changed without rewriting of the setting data in the serial register 11.

摘要： According to the present invention, it is possible to display an image signal with as a high picture quality as would have been obtained with a solid image pick-up device having color filters arrayed in a mosaic pattern. The image signal obtained from the solid image pick-up device with a Bayer array of the three primary colors of R, G, and B is separated by a color separation circuit 4 into R-color, G-color, and B-color signals. These color signals are attenuated by filters 6, 8, 10 respectively at half a horizontal sampling frequency in order to suppress the occurrence of moire noise. The G-color filter circuit 8 has a narrower attenuation band width than that of the R-color filter circuit 6 and the B-color filter circuit 10. These color signals thus filtered are adjusted in level at a white balance circuit 12 and then mixed by addition at a mixer 14, thus generating a luminance signal. By narrowing the attenuation band width of the G-color signal, the resolution can be kept high while suppressing the occurrence of moire noise.

摘要： In an image signal processor with which a group of control variables, having relevance to one another, stored in registers are activated synchronously with the switching of a picture, when a host sets the control variable group in the registers, mutual coherency is secured even if the setting operation extends beyond a pulse of a vertical synchronous signal (VD). In order to realize this, an operation for setting a control variable group in a register block (20) by the host, and an operation for reflecting the control variable group in a DSP block (22), are separately performed. After setting of the control variable group, the host sets H level in a VLAT register (30). In correspondence with this operation, a control portion (24) updates an output of a latch circuit (36). As a result, the control variable group is activated from the register block (20) to the DSP block (22).

摘要： An image signal is input to two LPFs having different transmission characteristics. A selector chooses one of outputs of the respective LPFs and delivers the chosen output to a gamma correction circuit. The switching of the selector is controlled by a filter control circuit. In the filter control circuit, a comparator compares an exposure time E of a current frame with a threshold value R. The selector is controlled so as to select an output of one of the LPFs that has a lower cutoff frequency and a greater noise component elimination effect than the other LPF does if the exposure time E is longer than or equal to the threshold value R.

摘要： Exposure control for a solid-state imaging apparatus can be completed in a short time. First exposure information D1 and second exposure information D2 are prepared. The first exposure information D1 is for adjustment of an exposure time L for a CCD (1) through extension or reduction in the unit of one horizontal scanning period; the second exposure information D2 is for direct designation of an exposure time L. When the power is switched on, the second exposure information D2 is selected for supply to a timing control circuit (3). After a lapse of a predetermined time, the first exposure information D1 is then selected.

摘要： An analog image signal is converted into a digital image signal which is in turn subjected to various types of processing procedures. The resulting digital image data is added to synchronizing data having the same range of data change as that of the image data to generate image data containing the synchronizing data. This image data is then converted into an analog image signal. An offset signal is applied to the analog image signal to adjust the voltage level of the synchronizing signal for obtaining an image signal containing a correct synchronizing signal.

摘要： In an image signal processing apparatus, line memories conventionally provided at a latter stage of the apparatus in order to convert a VGA image signal into a CIF image signal are eliminated. Image data of the VGA held in a unit of one line in plural line memories 60 provided in a digital signal processing circuit are weighted and added in a VLPF 62. A factor setting part 76 of the VLPF 62 changes weighting factors according to a positional relation between a position of a generation object line of the CIF and a line of the VGA. The weighting factors are determined so that a characteristic of trapping ½ of a vertical sampling frequency fv is also obtained. The VLPF 62 uses the weighting factors to trap fv/2, and changes the position of the vertical sampling point to a position of each line of the CIF image.
