Abstract: Preview mode low-resolution readouts occur, and then a shutter button on a camera is pressed, which causes an image sensor cleanout operation to occur. Following the cleanout, a high-resolution readout occurs. As rows of sensor values are read, the first rows are rows corresponding to a pre-defined horizontally-extending shielded area. There are no valid area sensor elements to either side of the horizontally-extending area. Data values read from the horizontally-extending area are used to determine optical black (OB) values that are then used to adjust the valid area values read out of the image sensor in that same frame. The same OB values are used throughout the adjusting of the valid area values of the entire frame. No values from the preview readouts are used in the OB value determination, so there is a clean break between the preview mode OB level and the high-resolution capture OB level.

Pixel data is read based on the determined read positions. When a pixel to be read overlaps two pixels, pixel data of the pixel to be read is produced (interpolated) from pixel data pieces. In this manner, the effects of camera shake are corrected. The present invention is applicable to video cameras.

By using horizontal electrodes to selectively assert predetermined vertical-driving signals of the vertical CCDs, the vertical CCDs receive and vertically transmit the image signals (charges) of active pairs of vertically adjacent rows. Each active pair of adjacent rows is separated by (at least) two (a pair of) inactive adjacent rows, and the image signal (charges) of the active pair of adjacent rows represent all three colors (R, G, B) of one line (or one field) of real-image pixels.

Abstract: An automatic exposure (AE) sensor includes a line-selecting circuit for line selection between horizontal lines and vertical lines, in addition to components of a typical AE sensor. The line-selecting circuit temporally filters a SYNC pulse for notifying a subsequent circuit about a pulse timing of an imaging signal to select a line to be read out and to cause the subsequent circuit to change an active pixel region. The number of selected lines is determined by an external input. The active pixel region is reduced when the AE sensor is incorporated in a device having a low performance CPU, thereby reducing load on the CPU. The active pixel region is increased when the AE sensor is incorporated in a device having a high performance CPU, thereby effectively using the CPU performance to achieve higher density control.

Abstract: A CPU 14 drives the CCD2 by switching its driving mode between an omission readout mode and a summation readout mode. Summing the signal charge of pixels in the summation readout mode offers an increased sensitivity. The omission readout mode reduces smear. The summation readout mode calls for reading out to the vertical transfer paths all red pixel signal charges of the two-color filters aligned along each vertical transfer path. While charge readout voltages are applied to a specific system of charge readout electrode systems, vertical transfer is performed to sum pixels of a like color on each vertical transfer path. Charges of the green pixels are read to the vertical transfer paths so as not to be mixed with the red signal charges. By combining vertical transfer with selective readout, pixels of the respective same colors are summed on the vertical transfer paths or the horizontal transfer path.
